Unanswered question about our visible
universe in the standard Big bang model is, surprisingly
enough, the contents of the Universe. Obviously, we can only directly `see’
matter that emits light particles, but today it turned out as a fact that most
of the matter in our observable Universe actually does not emit light [ They
are either the dark matter/ or dark energy]. For example, the visible parts the
of galaxies are thought to be surrounded by much larger `haloes’ of dark
matter, with a size up to 30 times that of the visible part. There also exist
dark galaxies as Rupak Bhattacharya told. If all this matter were visible, the
night sky would probably look pretty much like van Gogh’s `Starry night’.

Even though we
can only have indirect evidences for the
existence of this dark matter, we do have a reasonable idea yet of what it is.
About 4%- 5% of the matter of this
Universe is only visible. Another 5% is invisible `normal matter’, that is,
baryons (protons and Neutrons) and electrons. This is probably in the form of
massive compact

**halo objects**, such as**brown dwarfs**,**white dwarfs**,**planets and possibly black holes**. Roughly 25% of the matter of the Universe is thought to be `**cold dark matter’**(CDM), that is, heavy non-relativistic exotic particles, such as axions or WIMPS (weakly interacting massive particles). CDM tends to collapse (or `clump’) into the haloes of galaxies, dragging along the dark baryons with it**. Finally, 65% of the contents of this Universe is thought to be in the form of a `cosmological constant’, that is, Dark energy of the vacuum and probably “The gravity” : this can also be thought of as cosmic antigravity or the weight of space! Unlike CDM, this never clumps: it tends to**make the Universe `**blow up’ by making it expanding faster and faster like a balloon blowing with air**( given at bottom of this Blog). In other words,**it forces an accelerated expansion which, according to recent data, has begun very****recently. These data have been taken very skeptically by some people. In particular,****a period of future acceleration of the Universe, while not posing any problems for****cosmologists, would be somewhat problematic for string theory, as we know****it. However, this is not a basis for judgment: `data’ is not a dirty word, `assumption’ and `conjecture’ are in fact dirty words to me. These ingredients are needed for cosmological model building. One may starts with a theoretical model, `adds in’ cosmological parameters such as the age, matter, contents and so forth and computes its observational consequences. One must then compare notes with observational cosmologists and see whether the model is in agreement with our observations: if it does not agree then one had better to start again. In the hope of eliminating some of the shortcomings of the “Big Bang model or Standard Model of Universe Creation”, one needs to then generalize the model, and yet unexplored extra dimensions are a good places to look for answers.****Strings**and

**extra**

**dimensions**. It is now believed that the unification of the known fundamental interactions of nature requires theories with additional space-time dimensions. Indeed, the only known theory of gravity that is consistent with quantum mechanics is string theory, which is formulated in at least 10 dimensions (Polchinski 1998)-however we human being never can experience those Extra dimensions space time. Only in mathematics and in theory they can exist. It is not the fault of creator of the universe vaccum ,space time but our eyes and brain power does not permit to see other spaces. Even though there are at present no robust ideas about how one can go from these theories to our familiar low-energy space-time cosmology in four dimensions (three spatial dimensions plus time), it is clear that such a process will necessarily involve procedures known as dimensional reduction and compactification. These concepts are mathematically very elaborate, but physically quite simple to understand. Even if the true `theory of everything’ is higher dimensional, one must find how it would manifest itself to observers like us who can only probe four dimensions. Note that this is more general than simply obtaining low-energy or other limits of the theory.

On the other hand, given that we only
seem to be able to probe four dimensions, we must figure out why we cannot see
the others or, in other words, why (and how) they are actually hidden from us.
A simple solution is, to make these extra dimensions compact and very small.

**What is Gravity**Newton

**Of what force/ or what matter is it then composed? Rather the question may be asked of What Particles the gravity force is made of? Is it the Dark matter? Is it the Dark Energy? Is it the Higg Boson? Or is a zero mass Rupak particle? Is it simple wrapped up**

__space__-__time__?
For over a century, since Albert Einstein published his first paper
on his general theory of
relativity in 1905, physicists have struggled to resolve fundamental
differences between quantum theory and the continuum or yang miller field
theory. The field approach should have no singularities [Big bang or Big
crunch]; but the quantum approach has only singularities. Max Planck formulated
quantum theory in 1900, and Einstein could however successfully applied it in
1905 to electromagnetic radiation, when Einstein first hypothesized the photon
particle in Particle Physics, the inheritors of quantum theory, used a paradigm
of ballistic matter in non-reactive flat space, that was originally fashioned
using the Rutherford atomic model for the fixed nucleus and its orbiting
electrons, which was patterned after the solar system by Rutherford to win
Planets highest honor& Prize- a Nobel prize. The laws of conservation of
momentum and energy, and orbital dynamics did not translate well from the very
large realm to the very small, resulting in necessary modifications such as Rutherford atomic model, to
explain interactions of matter at relativistic speeds approaching "

**de Broglie waves**. Relativity, the successor to**field theory**,**had been there after repeatedly tested and was proven using atomic clocks, accelerated particles, and star light aberration of CS Chandrasekhar NL.**But other than explanations involving passenger trains and observers as originally presented by Einstein, relativity lacks a working visualization model like the*c*" the speed of light. Very little is found in scientific literature regarding common ground from which both particle physics and relativity can be derived. All of theoretical physics suffers from the lack of a definitive visualization model to guide research. The majority of developments in theoretical physics are driven by purely mathematical concepts and extensions of current theory.
The
most recent attempt at achieving common ground,

**that of String Theory**, fell victim in this struggle and was reduced to so called**Super Symmetry String Theory ,**being reinterpreted as super-short string segments embedded within the theoretical quark particles. Each miniaturized "super string" is supposed to have free ends whipping at the speed of light.**Exactly where from the required string tension comes from to support super high frequencies with unrestrained ends, and where the power comes from to sustain the oscillations, was never addressed till date**. Also left unanswered is any relevance of whipping ends inside the theoretical sub-atomic quark, to the transmission of light in free space. Compactifying string theory within the unobserved quark particle effectively marginalized string theory and ended its threat to the status quo.**What is space time?**

In physics,

**spacetime**(or*space–time)*is any mathematical model that combines space and time into a single continuum. Spacetime is usually interpreted with space being three-dimensional and time playing the role of a fourth dimension that is of a different sort than the spatial dimensions. According to certain Euclidean space perceptions, the universe has three dimensions of space and one dimension of time. By combining space and time into a single manifold, physicists have significantly simplified a large number of physical theories, as well as described in a more uniform way the workings of the universe at both the super galactic and subatomic levels. The concept of space-time combines space and time within a single coordinate system, typically with three spatial dimensions: length, width, height, and one temporal dimension: the time. Dimensions are components of a coordinate grid typically used to locate a point in a certain defined "space" as, for example, on the globe by latitude and longitude. In space time, a coordinate grid that spans the 3+1 dimensions locates "events" (rather than just points in space), so time is added as another dimension to the grid, and another axis. This way, you have where and*when*something is. Unlike in normal spatial coordinates, there are restrictions for how measurements can be made spatially and temporally. These restrictions correspond roughly to a particular mathematical model which differs from Euclidean space in its manifest symmetry. We live in a 3+1 dimensional space time with symmetry principles^{ }that, in the case of special relativity, require that the laws^{ }of physics be invariant under space time transformations. Symmetry^{ }and asymmetry have been powerful organizing concepts in a host^{ }of disciplines, including in physiology, biology, art and mathematics. More than a century^{ }ago, van’t Hoff pointed out a connection between molecular^{ }chirality and the fundamental symmetries in physics . In^{ }the case of biology, Pasteur was the first to recognize ‘‘symétrie’’^{ }at the molecular level and concluded from data on (+)- and (-)-tartaric^{ }acid that they represented non super imposable mirror images of^{ }each other (Fig. 1). Kelvin later introduced the term*chirality*^{ }for this type of asymmetry
Previously, from various important experiments at low
speeds,

**time was believed to be independent of motion, progressing only in forward direction, at a fixed rate**in all reference frames; however, later in early mid 20^{th}century, high-speed experiments revealed that time can be slowed down at higher speeds (with such slowing called "**time dilation**" explained in the theory of Einstein "**special theory of relativity**" ). Many powerful experiments later have confirmed time dilation, such as in atomic clocks, on board a Space Shuttle running slower than synchronized Earth-bound inertial clocks and at subatomic particles level the relativistic decay of muons from cosmic ray showers.**So time is always variable in space time**. The duration of time can therefore vary for various events and various reference frames. When dimensions are understood as mere components of a grid system, rather than physical attributes of space, it is easier to understand the alternate dimensional views as being simply the result of coordinate transformations. The term**has taken on a generalized meaning beyond treating space-time events with the normal 3+1 dimensions (including time). It is really the combination of space and time. Other proposed spacetime theories include additional dimensions—normally spatial but there exist some speculative theories that include additional temporal dimensions and even by some those included some other dimensions that are neither temporal nor spatial.***space-time***How many dimensions are needed to describe the visible universe is still an open question today**.**Speculative theories such as string theory suggests that vibrating strings that exist in 10 dimensions underpin the observable Universe [string theory no-3] or 26[string theory no-1]**dimensions ,when**M-theory predicts minimum 11 dimensions**:**10 spatial and 1 temporal**, but**the existence of more than four dimensions would only appear to make a difference at the subatomic**. For physical reasons, a spacetime continuum is mathematically defined as a four-dimensional, smooth, flat connected with__level or micro universe level__**Lorentzian manifold**(*M*,*g*). This means the smooth Lorentz metric*g*has signature . The metric determines the geometry of spacetime, as well as determining the**geodesics**of particles and light beams. About each point (event) on this manifold, coordinate charts are used to represent observers in reference frames. Usually,**Cartesian coordinates**(*x*,*y*,*z*,*t*) are used. Moreover, for simplicity's sake, the speed of light*c*is usually assumed to be unity. A reference frame (observer) can be identified with one of these coordinate charts; any such observer can describe any event*p*. Another reference frame may be identified by a second coordinate chart about*p*. Two observers (one in each reference frame) may describe the same event*p*but obtain different descriptions. Usually, many overlapping coordinate charts are needed to cover a manifold. Given two coordinate charts, one containing*p*(representing an observer) and another containing*q*(representing another observer), the intersection of the charts represents the region of spacetime in which both observers can measure physical quantities and hence compare results. The relation between the two sets of measurements is given by a non-singular coordinate transformation on this intersection. The idea of coordinate charts as local observers who can perform measurements in their vicinity also makes good physical sense, as this is how one actually collects physical data—locally. For example, two observers, one of whom is on Earth, but the other one who is on a fastest rocket to pluto, may observe a comet crashing into Jupiter or in pluto (this is the event*p*). In general, they will disagree about the exact location and timing of this impact, i.e., they will have different 4-tuples (*x*,*y*,*z*,*t*) (as they are using different coordinate systems). Although their kinematic descriptions will differ, dynamical (physical) laws, such as momentum conservation and the first law of thermodynamics, will still hold. In fact, relativity theory requires more than this in the sense that it stipulates these (and all other physical) laws must take the same form in all coordinate systems. This introduces tensors into relativity, by which all physical quantities are represented.**Spacetime in theory of special relativity**: The geometry of spacetime in special relativity theory is described as the

**Minkowski metric**on R

^{4}. This spacetime there is called Minkowski space. The Minkowski metric is usually denoted by η and can be written as a four-by-four matrix: where the Landau–Lifshitz spacelike convention is being used. A basic assumption of relativity is that coordinate transformations must leave spacetime intervals invariant. Intervals are invariant under Lorentz transformations. This invariance property leads to the use of four-vectors (and other tensors) in describing physics. Strictly speaking, one can also consider events in Newtonian physics as a single spacetime. This is

**Galilean-Newtonian relativity**, and the coordinate systems are related by Galilean transformations. However, since these preserve spatial and temporal distances independently, such a spacetime can be decomposed into spatial coordinates plus temporal coordinates, which is not possible in the general case.

**Spacetime in general relativity_:**In

**general relativity**theory, it is assumed that spacetime is curved by the presence of matter (energy), this curvature being represented by the

**Riemann’s tensor**particles. In special relativity, the Riemann tensor is identically zero, and so this concept of "non-curvedness" is sometimes expressed by the statement

**Minkowski spacetime is flat**

*.*Many space time continua have physical interpretations which most physicists would consider bizarre or unsettling. Let me tell you that for example, a compact space-time has closed, time-like curves, which violate our usual ideas of causality (that is, future events could affect past ones). For this reason, mathematical( theoretical) physicists like me usually consider only restricted subsets of all the possible spacetimes. One way to do this is to study "realistic" solutions of the equations of general relativity. Another way is to add some additional "physically reasonable" but still fairly general geometric restrictions and try to prove interesting things about the resulting spacetimes. The latter approach has led to some important results, most notably the

**Penrose–Hawking singularity of the time which ultimately was disproved**

**Quantized spacetime**

**[3+1 spacetime**] or

**Rogers**

**Penrose_ S.W Hawking”s Space time concept**In the general theory of relativity, space time is assumed to be so smooth, flat and continuous—and not just in the mathematics. In the theory of quantum mechanics, there is an inherent discreteness present in physics. In attempting to reconcile these two theories, it was sometimes postulated by some physicists like Penrose And Hawking that space time should be quantized also at the very smallest scales.

**Current theory is focused on the nature of space time at the Planck scale. Causal sets, loop quantum gravity string theory, and black hole thermodynamics**

**, all these theories predicts a quantized spacetime with agreement order of magnitude.**Loop quantum gravity makes precise predictions about the
geometry of

**spacetime at the Planck scale**. Privileged character of 3+1 spacetime Reasoning about spacetime is always limited by the scientific evidence and technology available. For example, in the latter 20th century, experiments with many particle accelerators revealed that protons gained mass when accelerated to super & super high speeds, and the time required for particle decay and other physical phenomena rose. Special relativity predicted this. Authors here are writing before Einstein's discovery of special relativity were unaware of these facts, so that their views were often mistaken, even fanciful.

**In the Universe,**(

^{ }there are two kinds of dimensions, spatial**bidirectional) and temporal (unidirectional**).

**Let the number of spatial dimensions be**

*N*and the number of temporal dimensions be*T*. That*N*=3 and*T*=1, setting aside the compactified dimensions invoked by string theory and undetectable to date, can be explained by appealing to the physical consequences of letting*N*differ from 3 and*T*differ from**1**. Immanuel Kant once argued that 3-dimensional space was a consequence of the inverse square law of universal gravitation. While Kant's argument is historically important, John D. Barrow in 2002 said that it "...gets the punch-line back to front: it is the three-dimensionality of space that explains why we see inverse-square force laws in Nature, not vice-versa

**." This is because the law of gravitation o**r any other inverse-square law follows from the concept of flux, from

*N*=3, and from 3-dimensional soloid objects having surface areas proportional to the square of their size in a selected spatial dimension.

**In particular, a sphere of radius**In 1920, Paul Ehrenfest showed that if we fix

*r*has area of 4π*r*^{2}. More generally, in a space of*N*dimensions, the strength of the gravitational attraction between two bodies separated by a distance of*r*would be inversely proportional to*r*^{N}^{-1}.*T*= 1 and let

*N*>3, the orbit of a planet about its sun cannot remain stable. The same is true of a star's orbit around the center of its galaxy. Ehrenfest also showed that if

*N*is even, then the different parts of a wave impulse will travel at different speeds. If

*N*>3 and odd, then wave impulses become distorted. Only when

*N*=3 or 1 are both problems avoided.

**In 1922, Hermann Weyl showed that Maxwell's theory of electromagnetism works only when**,

*N*=3 and*T*=1, writing that this fact "...not only leads to a deeper understanding of Maxwell's theory**but also of the fact that the world is four dimensional, which has hitherto always been accepted as merely 'accidental,'become intelligible through it. Finally, Tangherlini showed in 1963 that when**Max Tegmark expands on the preceding argument in the following anthropic manner

*N*>3, electron orbitals around nuclei cannot be stable; electrons would either fall into the nucleus or disperse.**. If**.

*T*differs from 1, the behavior of physical systems could not be predicted reliably from knowledge of the relevant partial differential equations. In such a universe, intelligent life capable of manipulating technology could not emerge**Moreover, if**. (This is not a problem if the particles have a sufficiently low temperature.) If

*T*>1, Tegmark maintains that protons and electrons would be unstable and could decay into particles having greater mass than themselves*N*>3, Ehrenfest's argument above holds; atoms as we know them (and probably more complex structures as well) could not exist. If

*N*<3, gravitation of any kind becomes problematic, and the universe is probably too simple to contain observers. For example, when

*N*<3, nerves cannot overlap without intersecting.In general, it is not clear how physical law could function if

*T*differed from 1. If

*T*>1, subatomic particles which decay after a fixed period would not behave predictably, because time-like geodesics would not be necessarily maximal

*N*=1 and

*N*=3 and

*T*=1—which happens to describe the world about us. Curiously, the cases

*N*=3 or 4 have the richest and most difficult geometry and topology. There are, for example, geometric statements whose truth or falsity is known for all

*N*except one or both of 3 and 4.

*N*=3 was the last case of the Poincare conjecture to be proved.For an elementary treatment of the privileged status of

*N*=3 and

*T*=1, see chpt. 10 (esp. Fig. 10.12) of Barrow;for deeper treatments, see §4.8 of Barrow and Tipler (1986) and Tegmark. Barrow has repeatedly cited the work of Whitrow.

**String theory was built on the hypothesis that the "universe is wiggly**" and theory hypothesizes that matter and energy are composed of tiny vibrating strings of various types, most of which are embedded in dimensions that exist only on a scale no larger than the Planck length. Hence

*N*=3 and

**So what about the space time in the string theory**?

**. I can rather call this invisible double helix the**

*Space-time is defined there as an invisible, underlying matrix woven from a double helix having one atomic diameter cross-section and infinite length, always traveling at the speed of light "c" along its axis*. It is the power source and regulator of the entire universe**Space-time Helix (STH)**because it defines the limits and dimensions of space by its ubiquitous presence and extension. It marks time at the most fundamental level by its resulting crest-to-crest sine wave spacing (wavelength),

**while traveling at**. The STH produces all known rotational phenomena without actually rotating. A traveling helix gives the appearance of rotation without actually rotating, yet it can induce rotation in an intersecting plane of detection through which it slides. We tend to think of a helix in terms of the “Archimedes' screw in which a rotating screw lifts water; the screw turns and the water doesn't. The STH works in the opposite manner;

*c*; and the term "helix" incorporates its cork-screw shape**the STH doesn't rotate but it causes rotation of the electrons and nucleons formed by two intersecting space-time helices**. If the STH were forced to rotate, it would soon twist into a hopeless knot.As long as the double helix travels longitudinally at speed

*c*in a balanced state without lateral displacement or vibration, it remains hidden and does not intrude into our reality.

**Once the STH is disturbed laterally or longitudinally, by being struck or forced out of balance, it is capable of producing all known vibrational frequency particles**,

**both short-lived and long-lived**. The STH is the hidden power source for all that exists and occurs in the universe. The STH is described as follows –[ A Personal Communication with Prof Pranab Kumar Bhattacharya to Robby York And from previously Published Blogs of Professor Pranab kumar Bhattacharya with 7 all comments “

__Time__**s nothing more than fixed periodicity established at the most primal level.**

__i__**The basic time is the standard of the entire material universe, shared by every atom, is the rotational frequency of its constituent electrons, and the corresponding rotational frequency of its nucleons that are paired to its electrons by the STH structure**.

**Time renormalizes at every electron, proton and neutron in the universe**because an STH imposes its rotational frequency on an intersecting node-paired STH, which in turn is forced to the same rotational frequency by the STH it intersects. That is why the universe, other than for spectral red shift or spectral blue shift does not appear to radically depart from a common time base.

**Relativistic time dilation**

**occurs when a pair node (atom) is accelerated to speeds approaching the speed of light**

*c*.**At higher speeds of light such as with tachyons the**two space-time helices are drawn into a narrow "V" trailing the atom, but each STH continues to course through the atom from a lagging position toward the leading position. If one STH is oriented by direction of flow opposite to the direction of travel of the atom, this opposing STH folds to trail the atom, for the simple folk reason that it is impossible to push a rope (see Figure 3). A rope can only be pulled because it is flexible, just like the STH. The rope, in this case the STH opposing the direction of travel, folds as the atom drags it along.

**In normal space-time, time can flow only in one direction, unless the STH is stiffened by an intense magnetic field. As the speed of the atom approaches**If it were possible to move an atom at speed

*c*, both helices become more aligned in the direction of travel.*c*, the two helices would become essentially overlaid and could be treated as a single helix with uniform rotation. Rotation speed of the electron depends upon the differential between the speed of the pair node (atom) through space, and the speed of the STH which always travels at speed

*c*. As the differential decreases, the apparent rotational speed of the electron slows .At speed

*c*, the speed of the atom and electron would match the speed of the STH, so the STH could no longer force the electron to rotate; time for the atom and electron would stop, and the electron would become a stationary node riding the STH. An atom cannot be pushed to speed

*c*, because of relativistic mass increase which prevents the atom from reaching speed

*c*. The same behavior would be true for nucleons in the atom. Time dilation is [shown in Equation as mentioned bellow]relativistic which relates the motion of one observer to another without benefit of an underlying matrix common to both observers. The Clopton Model provides an inertial frame of reference travelling at speed

*Relativistic mass increase*is linked to relativistic time dilation. At higher speeds the two space-time helices are drawn into a narrow "V" trailing the atom (see Figure 4). As the moving atom approaches speed

*c*, the "V" narrows even more, so that the atom is physically dragging along both of the space-time helices.

**It was entirely possible that the universe is made of only one STH string, wrapped countless times around the universe like a ball of yarn stretching and expanding as a shell**(see Big Bang and the Shape of the Universe). As an accelerating atom approaches the speed of light and time slows for the atom, it becomes mechanically coupled to the space-time helix, so that the atom is actually attempting to drag the entire universe (see Relativistic Time Dilation, above). The formula for relativistic mass increase shows that the mass of any body becomes infinite at speed

*c*, so matter can never be accelerated to the speed of light. The given formula for relativistic mass increase is shown in Equation 2.

**So what is string theory? Why it is required?**

The Great Mathematician, Pythagoras could be however according myself called the first known string theorist. Pythagoras, an excellent lyre player, figured out the first known string physics - the harmonic relationship. Pythagoras could some how realize that vibrating Lyre strings of equal tensions but of different lengths would produce

**harmonious notes**(i.e. middle C and high C) if the

**ratio of the lengths**of the two strings were a

**whole number**. Pythagoras discovered this by looking and listening. Today that information is more precisely encoded into mathematics, namely the wave equation for a string with a tension T and a mass per unit length . If the string is described in coordinates as in the drawing below, where x is the distance along the string and y is the height of the string, as the string oscillates in time t, then the equation of motion is the one-dimensional wave equation will be according to me=

δ

^{2 }y(x,t)/ δt^{2 =}√^{ }T/m δ^{2}y(x,t )/ δx^{2}=v^{2}_{w/}δ^{2}y(x,t )/ δx^{2 }_{ }**where v**. When I was solving the equations of motion, I also need to know the "boundary conditions" of the string. Let's me suppose that the string is fixed at each end and has an un stretched length L. The general solution to this equation can be then written as a sum of "normal modes", here labeled by the integer n, such that ; y(x,t)=Σ_{w}is the wave velocity along the string^{α}_{n=1[}a_{n}cos nπv_{w t}/L+b_{n}sin nπv_{w}t/L]sinπx/L .The condition for a normal mode is that the wavelength be some integral fraction of twice the string length, or λ_{n}=2L/n. The frequency of the normal mode is then

According to Centuries greatest scientist Einstein's theory, a relativistic equation has to use coordinates that have the proper

The classical equation can be then written as per me

_{n}=nv_{w/}2L . The normal modes are what we hear as notes in a base Guitar. Notice that the string wave velocity v_{w}increases as the tension of the string is increased, and so the normal frequency of the string increases as well.. This is why a base guitar string makes a higher note when it is tightened. But that's for a non relativistic string, one with a wave velocity much smaller than the speed of light. How then do I write the equation for a relativistic string?According to Centuries greatest scientist Einstein's theory, a relativistic equation has to use coordinates that have the proper

But then I have to face one problem, because in the string theory , a string always oscillates{ who knows why it is always oscillating] in space and time, and as it goes on oscillates, it sweeps out a two-dimensional surface in space time that I can call it now a**world sheet**(compared with the**world line**of a particle). In the**So there will be a clear difference between the space coordinate along the string, and the time coordinate. But in a relativistic string theory, we wind up having to consider the**__non relativistic string,__**world shee**t of the string as a**two-dimensional space time**of its own, where the division between space and time depends upon the observer.The classical equation can be then written as per me

The

represents the approximate distance scale at which string effects should become
observable.

**In the generic quantum string theory, there are quantum states with negative norm, also known as ghosts**. They are made of thus anti particles This happens because of the minus sign in the space time metric, which implies that**So there ends up being extra unphysical states in the string spectrum.**

**In 26 space time dimensions, these extra unphysical states wind up disappearing from the spectrum. Therefore. bosonic string quantum mechanics is only consistent if the dimension of space time is 26**and it appears to me absurd to me. Why we do not then see all those extra Space time dimension if I exist. Are they Wrapped up. Who then wrapped them up?

**By looking at the quantum mechanics of the relativistic string normal modes, one can deduce that the quantum modes of the string look just like the particles**

**we see in space time, with mass that depends on the spin according to the formula**

Please remember that boundary conditions are very important for string
behavior. Strings can be open, with ends that may travel at the speed of light c, or strings
may be closed, with their ends joined in a ring.

**The main alternative theory of the origin of the structures (mass) of the universe are these cosmic strings or super heavy strings****which are predicted too form in the early universe by the Grand Unified****Theory (GUT) in inflationary “ Big Bang model**.**Loops of such cosmic strings were then seed****of all the galaxies**. They were**super heavy strings, formed at phase transition or****condensation that took place when the universe was cooled after GUTS in the very early universe**.**Kibble{ Will he get ever the Nobel Prize in physics?- he should} had once suggested that GUTS strings played an important role in the****evolution of the Universe and the strings provided the in-homogenity leading to the formation of galaxies.**In the very early universe**Strings were predicted to be formed at symmetry breaking phase transition**by those in grand unified theories (GUTS) in which vacuum ( space Time) had the appropriate topology.**Cosmic Strings were the****configuration of the matter**fields, which owe their topology of the space of degenerate vacuum,**produced in the phase transition**, in the early universe. Let me ignore the internal structure of the strings and treat them as one-dimensional object with tension. In the resting frame of the strings, the mass per unit length μ to the tension.**The equality of the line of the density and the tension caused the typical velocity associated with large vibration on the strings to be close to speed of light.**The strings cannot end but can either close on themselves or can be extended to infinity.**The closed strings are****loops.**
Whenever two long strings cross each other, they
exchange ends, or `inter commute' (case (a) in the figure below). We had
already encountered this apparently strange fact when we discussed the strings
in the context of nematic
liquid crystals. In particular, a long string can inter commute with
itself, in which case a loop will be produced (this is case (b) below).

As with any object in tension, strings would also
accelerate so as to try to become straight. Damping of the string motion was
due to their non gravitational interaction with other matter, those become
negligible as soon as the strings were formed.

Example**Strings that extended outside the horizon were conformably stretched by the cosmic expansion**.**Thus at a given epoch, these strings were straight on their length & scale, but were smaller then the horizon size, but was quiet convoluted on large scale lager then this. The typical velocity was associated with the straightening of a string and was close to the speed of light and**the velocity field of the string extending outside the horizon was relativistic and approximately constant over scale much smaller than a horizon size.**Once a loop entered the horizon it no longer expanded but rather started oscillate with a period comparable to light travel time across it. This motion was damped by gravitational radiation causing the size & period of the loop to decrease approximately linearly with time**The Fractional decrease in size, period,& mass of the strings in one oscillation was given by equation* Gμ where G is Gravitational constant.**A string will decrease to zero size in a finite amount of time loosing its energy by Gravitational Radiation**. The distribution of strings in our universe was not quite so well understood1]

These pictures show

1) a full three-dimensional simulation of the inter commuting of two cosmic strings...

**The reconnection and `exchange of partners' when two strings intersect. In this three-dimensional simulation, the strings approach each other at half the speed of light. Notice the radiation of energy and the production of a small interaction loop in the aftermath of the collision [ Picture By Rupak Bhattacharya].**

2]

The scattering of two vortices is highly non-trivial; the two vortices approach and form a donut from which the emerge at right-angles have `exchanged halves'

3]

Both long cosmic strings and small loops will emit radiation. In most cosmological scenarios this will be

**gravitational radiation**, but electromagnetic radiation or axions can also be emitted in some cases (for some specific phase transitions). Here is a single, oscillating piece of string

4]

*Radiation fields from the oscillating shown above. A transverse cross-section of the fields has been made at the point of maximum amplitude. Notice the four lobes of the radiation (a quadrupole pattern) which is characteristic of all cosmic string radiation*

5] The effect of radiation is much more dramatic for loops, since they lose all their energy this way, and eventually disappear. Here you can see what happens in the case of two interlocked loops. This configuration is unlikely to happen in a cosmological setting, but it is nevertheless quite enlightening. Notice the succession of compicated dynamic processes before the loop finally disappears

. After formation, an initially high density string network begins to chop itself up by producing small loops. These loops oscillate rapidly (relativistically) and decay away into gravitational waves.

*The net result is that the strings become more and more dilute with time as the universe expands.*From an enormous density at formation, mathematical modelling suggests that today there would only be about 10 long strings stretching across the observed universe, together with about a thousand small loops!

In fact the network dynamics is such that the string density will eventually stabilize at an exactly constant level relative to the rest of the radiation and matter energy density in the universe. Thus the string evolution is described as

**`scaling'**or scale-invariant, that is, the properties of the network look the same at any particular time

*t*if they are scaled (or multiplied) by the change in the time. This is schematically represented below:

After
the phase transition, the strings were formed in a random network of
self-avoiding curves/loops. Some of the strings were in closed loops and some
were as infinite strings. The distribution of strings so happened that a
constant number of loops entered the Horizon. If the infinite strings would
simply straighten out, then the numbers of open
strings across the horizon-sized volume would also increase with time and
strings would soon come out to dominate the density. Velenkin
.A [Physics Review D23, p852; 1981] showed
that the geometry produced by the gravitational field near a length of straight
string is that of Minkowski space with a three dimensional wedge taken out of
each space like slice. The vertex of the wedge lies along the length of the
string and the angle subtended by missing wedge lies in rest frame of the
string and is equated asδπGμThe two exposed faces of the strings are thus
identified. Thus the Space Time remained flat everywhere except along the Strings , where it was highly curved. If
Gμ<<1, then the stress energy of the strings would produce only small
(lenier) perturbations from the metric
of rest of the universe. Because
the matter in the Universe did not produce
significant purturbation from the Minkowski metric
Space ,on scale ,less then horizon, the Gravitational field at a point much
closer to a length of a string would be
essentially then the same as gravitational field at a similarly located point in
Minkowski space. In the rest of frame of
the strings, all particles were when passing
, the strings were deflated by an angle 8πG μ
with respect to all particles passing on other side of the strings. The
magnitude of discontinuity in temperature(While
passing of particles) across the string was
δT/T= 8πGβ, where β=Transverse Velocity
of the strings which was typically
was close to Unity. This Jump of temperature persisted on angular
distance away from the string,
corresponding to the present angular size of the radius of curvature of the strings.
The magnitude of temperature jump was then independent of the Red shift (Z) at
which Light Rays reaching to us, passed by the strings. If we calculate the general properties of microwave sky anisotropy in string mode , then let us assume that microwave photons were last scattered at Red shift Z
1s. In a perfectly homogenious
Universe ,the matter became mostly
neutral and optically then at Z˜ 1000. However in a Universe with strings, there will be large
amplitude in homogeneity on small scale and the heat output from objects forming at or before Zγee may re -ionize
the plasma. If the plasma were kept fully
ionized then Z1s>10 and we have 1000>Z1s>10,the angle subtended by a
horizon-sized volume space at Z

_{1c}is o_{1s}^{-1/2}<<1. One would do expect to see on a round patch of sky of strings per horizon volume at red shift Z, will project to one length of string of angular size o if z<z1s. These strings will be moving relativistic ally, as they were unable to straighten themselves out of these length scale. In the modern Gauge theories of fundamental interaction of the Vacuum was far from being nothing. Rather it is now recognized as a dynamical object that was in different state. The current state of vacuum affects the properties such as masses and interaction of any particles put into it. Although the vacuum is thought to lie in it’s ground state ,that with the lowest state of energy, this state had not always been the same. Thus in the early universe when the particle component [ordinarily matter and radiation] was at a very high temperature, the vacuum adjusted it’s state in doing so modified the properties of particles so as to minimize the free energy of the entire system. [Vacuum plus particles. ] e i. the vacuum went into higher energy state in order to lower the energy of hot plasma by even greater amount. As the universe cooled to keep the entire system at the lowest possible energy at a given temperature , the vacuum had to change eventually, ending up in it’s present state which is nearby the true or zero temperature vacuum. It was possible in early universe that as the Universe expanded , the cooling happened too rapidly for the vacuum to find it’s true ground state and the vacuum was frozen into ground state with defects. Defects that probably could occur in a three dimensional space could be Zero dimensional (Monopoles), Two dimensional (Domain walls) or One dimensional (Strings). The Strings are macroscopic objects. In most cases of cosmological interest they have no ends and are either infinitely long or closed in a loop**At GUT’s the Strong, Weak and Electromagnetic forces behaved as if, they had equal strength,**much as line defects found in the crystal.

**Because of their enormous tension**

**ε/G , the net work of the Strings were formed in the phase transition. In this Theory the Strings contributed only a small fraction of mass of the Universe.**

**The Galaxies were formed by Accreating of ordinary matter about the Strings.**

**The Strings were stretched by subsequent expansion of the Universe on waves, on a given scale and began to oscillate then. The strings underwent Oscillation in which the Transverse intertia acted as weight and the restoring forces were provided by longitudinal tension of the strings.**As a result of oscillation in such that the scale entered the particles horizon and whenever the strings crossed itself and exchanged particle partners and produced closed Oscillating loops of the Strings with long life(Peebles.

**The Strings actually underwent Oscillation in which the Transverse inertia**acted as weight and the resting force was provided longitudinal tension of the strings

**. The gravitational field of these strings loops caused accretion of matter around them.**Brosche. P.J in the journal of Astrophysics stated that

**angular momentum of an astronomical object is proportional directly t square of mass and constant of proportionality is comparable to String Theories, which suggest that the Universe had evolved through hecrchial breaking of rotating or oscillating strings and the angular momentum with mass between various classes of different objects ranging from planets to super clusters**(brosche.PZ.J-Astrophysics Vo 57; P143; 1963). For the almost past three and half decades, a variety of Grand Unified Theories (GUT’S) had been developed to unify the strong and electro weak interactions at an energy scale of 10

^{16}Gev.

**GUTs are Gauge invariant point field theories (yang Mills), which do not incorporate Gravitational forces**and henceforth there remains few theoretical constrains on the possible internal symmetry group. The most favored Guts theories are based on the special unitary group Su (5), the special orthogonal Group SO (10) or the Exceptional Group E

_{6}. In such Guts theories “Quark’ and “Leptons” make up three of these families, are unified in one family. Super symmetries an important ingredient in Guts. It is a symmetry that relates to “Fermions” and particles of different spins. But supper symmetry is not an internal symmetry but amounts to an extension of the Space &time in super space that includes extra spinorial anti commuting co-ordinates as well ordinary co-ordinates.

**Super Symmetry requires particles Known as” s-quarks”, s leptons”, winos, Zinos, R –particles( a zero mass Rupak Particles} which have yet to be discovered. Super gravity theories are point field theories that incorporate local or gauged supper symmetry and thereby enlarging Einstein Theory of relativity. T**he basic idea of Gauge theory is that a continuous Symmetry or global invariance properties of Lagaragian field theory that can be made into a local invariance by introducing compensating gauge field in to the theory. This means that given a field theory, which possesses symmetry such as U

_{1}(1), Su (2), Su (3) or any other U group.

**The theory can be extended to a gauge theory, which has the symmetry at each part in the space-time individually**.

**The new symmetry is then called gauge symmetry**because it implies that we can choose our measuring standard gauge differentiate through out space-time without changing physics of the theory.

**The most familiar example of a gauge theory is Electromagnetism. In Quantum Electrodynamics the quantum field theory of electromagnetic interactions are charged particles and Boson (photon) is the most successful gauge theory**. The behavior of a relativistic String moving in space-time differs significantly from that of a structure less point particle. Unlike a point particle, a classical relativistic string has an infinite number of vibrational modes with arbitrarily high frequencies and angular momentum.

**This means that in quantum theory, a single string has an infinite number of states with masses sand spins which increases without limit.**The string theories were developed in early 1970s as model of strong interaction physics.

**A Meson has thought of as a string with a quark attached to one end while an anti-quark to the other end**. The string tension (T) was supposed to be _1Gev

^{2}and the excited states of the string were supposed to be hadrons. The main theories were “Boson Theory” [Boson particle are particles in the name of Prof. S.N. Bose of kolkatta, W.B ,

**Super string theories, that evolved from spinning string theories, that incorporated suppersymetry and had no Tachyonic ground states**. Super string theories hence offered the possibility of constructing a consistent quantum theory that unifies all interactions including the gravity and natural mass scale set by string tension (T) in Plank scale [ T

^{1/2}=10

^{9}Gev]. The excited states were so massive that they could be taken to be infinitely heavy and the theory can be approximated by an effective point field theory of the mass less state only. At energy scale bellow the planks scale the string looks like a point.

**One of the constrains in any string theory is that all string theories contain mass less spin-1 and Spin-2 particles which are associated with “yang mills Gauge Boson” and Gravitation.**Furthermore the original “Bosonic String Theory” required 26 space time dimension whereas super string theory only ten(10) dimensional space Time

**. We live in only three (3) dimensional Universe and we can at best imagine Four (4) dimensional space-time. Then where are these Extra Six Dimension in super string theory? Or extra 22 dimensions Bosonic String theory**?

**May be these extra dimensions are curled up**[they may be as large as our three dimension or may be too small to see and only in mathematical presence] coiled up and finally became very small by compactification in super string theory.

**There are three types of Super String theories**

**. Type 1 super string theory**describe the dynamics of open strings that have their free end points. The string carries quantum numbers in the n-dimensional, defining representation of a classical group G=S0 (n) or the simplistic group USP (n) at their end points SU (n). This is similar to the way in which “quark quantum numbers” were incorporated in the original string picture of mesons.

**Inflation was the only way of explaining several of otherwise extra ordinary initial conditions of the universe. But for fine tuning of inflation required a critical density of the universe. T**hus at least 85% of the universe could not be then the baryons matter and more then 60% of the matter of this Universe so did not cluster again into galaxies. The density of the matter on the universe must be greater then the baryonic upper limit .To make the things a little more difficult, it was said, that” the special co-relation function of rich cluster of galaxies had revealed strong clustering of very large scale up to 150 MPC.” This co-relation function of clustering of galaxies was 18 times stronger then the special co-relation function of galaxies.

**It was also found that the largest scale of the universe seem to look filamentous [Strings are filamentous] with large voids and large clumps . W**ith the GUTs an excellent way appeared to produce the distribution of size of universe. In normal generation and application of GUTs [a fluctuational spectrum with equal powering all scale formed naturally] it was assumed that there was no special co-relation between large scale and small clumps. They each had a random probability of occurring anywhere in the universe.

**On the other hand, it means, that strings are still being produced in the some spectrum, somewhere, &in some size**. Different proposals so had been put to solve the problem. But no models could solve it, as long as it was assumed that the primordial fluctuation had random phases. For example- a model based on Neutrinos produces both critical density and large-scale structure [filaments, voids, cluster co-relation function] but did not account for early formation of galaxies (Bachcall.N- J Astrophysics Vol 270; p20; 1983). Models evoking heavy or slow moving particles [like Gev mass photinos, gravitinos, axions, planetary mass black holes] however fits the small scale structure galaxy co-relation function, formation of time & so forth as well as building hierarchal to yield clusters but it do not allow critical density of the universe to be reached.]. Even the hybrid models, - with low- mass and huge - mass ions also runs problem, because of low- mass particles smear out the small-scale structure of universe.

**A more natural solution of the problem might be non-random phases of string model. J.E Peebles (Nature Vol-311; P517; 1984) noted that the non random phases of string model of the Universe yields large scale filaments and voids, as super heavy strings attract galaxies and cluster and gives string cluster- cluster co-relation**. Work by J.E. Peebles showed that a model based on clustering of galaxies about filaments [here strings] fit higher 3 and 4 points co-relation function for galaxies as well as hierarchical clustering. This model also enables density growth in some areas without producing a large universal background anisotropy and so

**could enable baryons to be dark matter on**

**galaxy and cluster state with non-baryonic stuff being a critical density background as dark energy. The degree of random to nonrandom phases in such a model depends upon density of strings in the space. In the limit of space being completely filled with strings, the strings picture also gives random phases.**Even if strings densities are large enough to randomize phases, their mere existence would still alter galaxy –in formation, calculation, because it were the strings rather then matter that would carry the fluctuation.

**The basic things of string theory say that-:**

*

**we live in accelerating and expanding universe today******String theory support the inflation theory where a period of rapid expansion happened in the early universe history.*******Most of the theories in the string theory are focused on understanding of theory of unbroken super-symmetry**. ******In string theory De-Sitter Space can arise only when super-symmetry is broken ( Rupak Bhattacharya& Ritwik Bhattacharya’s( 7/51 of Purbapalli Sodepur Kol-110 W.B India) Theory).**Breaking supper-symmetry in the string theory requires us to come face to face with problem of moduli stabilization. In string theory Vacuum with N≥2 super-symmetry, there are many flat direction or modules.

The flat directions are however very bad in cosmology**. Flat directions cause however problems in standard model. They ruin the successful prediction of Big Bang Theory**.
The big Question hat one of author of this

**Does the string theory allows at all De sitter Universe? Vacuum with negative cosmological constant to anti de-sitter space and Inflation theory of Big Bang?”**This was of course a great question, exactly not yet solved.

It is known that the de- Sitter space can only
arise if super symmetry is only broken. In string
theory with ≥2 super-symmetry there are many flat directions. The energy as we
go along these spaces is a constant & in fact vanishes identically and
these flat directions are bad news from the part of Big Bang cosmology.
Cosmology flat directions cause problems in standard model of Big Bang and ruin
the successful prediction of Big bang nucleo-synthesis. In these
compactifications besides curling up the extra dimensions preserved in the
string theory to small size, fluxes are also turned on along the compactified
directions. The fluxes includes higher form generalization of magnetic fluxes
in the electromagnetism turning them on charges, the potential in moduli
spaces, so that new minima arise in regions or field space where the potential
can be calculated with control. The value of Cosmological constant in this
minima can also be can also be calculated with a positive value give rise to
De-Sitter universe.

The String theory
started its journey in the
late 1960s as a very important tool
to explain the strong forces between nuclear atomic particles, but was
replaced in the 1970s by the more successful New York . Scientists discovered that string
theory could be as useful as QCD in explaining the strong nuclear forces
involved in a

**quantum chromodynamics (QCD) theory**.String theory went off in its own direction, acquiring ever more baroque layers of mathematical complexity. Some physicists found it anathema that the only way the resulting theories could be tested required energies far higher than those achievable in particle accelerators. But in 2005, string theory did find its way, albeit indirectly, into one accelerator: the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory in**quark–gluon plasma**.This new state of matter, comprising the basic constituents of protons and neutrons, was created in the hot mash-ups of gold ions generated at the RHIC. The key to this discovery was a mathematical technique in string theory that embodies the principles of holography, in which information contained in a higher dimension can be embedded in one fewer dimensions — just as a three-dimensional image can be stored within a flat, two-dimensional hologram. The latest claim for string theory is that it is a key tool in explaining the normal behavior of materials that conduct electricity without any resistance at relatively high temperatures. The theory that explains conventional superconductivity at temperatures close to absolute zero is well-developed — but the theory that explains the behavior of a second class of materials, which can superconduct at temperatures as high as 70K, remains something of a mystery**There remain always a fundamental asymmetry in the distribution of the**

The primary amino acid sequence determines the structure and^{ }function of a protein. The two most common structural motifs^{ }are the -helix and ß-sheet. Although -helices are^{ }now more abundant in proteins than ß-sheets, it is^{ }thought that the ß-sheet occurred earlier during chemical^{ }evolution . Generally, L-amino acids form a right-handed^{ }helix; a right-handed helix exhibits optical rotation of its^{ }own. Similarly, ß-sheets are not flat but, if made^{ }of L-amino acids, exhibit a right-handed twist when viewed along^{ }their strands. This right-handedness of turn arises from energetic^{ }constraints in the bonding of L-amino acids; a chain consisting^{ }of D-amino acids would produce sheets with a left-handed twist^{ }.^{ }Indeed, the circular dichroism (CD) spectrum produced by the^{ }all-D enantiomer of the full-length ß-amyloid peptide^{ }(42 amino acid residues) was a mirror image of the spectrum^{ }obtained with the natural all-L enantiomer, indicating that^{ }the two enantiomers had opposite optical rotation .

__STH and Gravity__
Gravity however
may be defined as an invisible, underlying matrix woven from a double helix
having one atomic diameter cross-section and infinite length, always traveling
at the speed of light "Newton who worked out so many useful formulas to apply
when working with the actions of gravity was pressed for an explanation as to
how gravity works he stated that the force of gravity is due to God himself.
Prof. Albert Einstein NL considered
gravity and came up finally with theories of “General Relativity” which is the
notion that gravity is due to a "bend" in space time and was able to
present the situation such that gravity had no "force” Ie not any particle.
Light
from a distant object (like a galaxy) gets bent by the gravity of a second
object that lies along the line of sight between us and the first object as

*c*" along its axis.**Gravity is probably the real power source and regulator of the entire our visible universe. Space-time helix interactions,**I can call this invisible double helix the Space-time Helix (STH) ,because it defines the limits and dimensions of space by its ubiquitous presence and extensions. It marks time at the most fundamental level by its resulting crest-to-crest sine wave spacing (wavelength), while traveling at*c*; and the term "helix"{ Reference-1} incorporates its cork-screw shape{1}.__The STH produces all known rotational phenomena without actually rotating__. A traveling helix gives the appearance of rotation without actually rotating, yet it can induce rotation in an intersecting plane of detection through which it slides. We tend to think of a helix in terms of the “Archimedes' screw in which a rotating screw lifts water; the screw turns and the water doesn't. The STH works in the opposite manner; the STH doesn't rotate but it causes rotation of the electrons and nucleons formed by two intersecting space-time helices. If the STH were forced to rotate, it would soon twist into a hopeless knot. As long as the double helix travels longitudinally at speed*c*in a balanced state without lateral displacement or vibration, it remains hidden and does not intrude into our reality. Once the STH is disturbed laterally or longitudinally, by being struck or forced out of balance, it is capable of producing all known vibrational frequency particles, both short-lived and long-lived[1}.__The STH is the hidden power source for all that exists and occurs in the universe[1]__. The**Gravity and Gravitation****is that hidden power force for all that exists and occurs in the universe as per authors view**^{ }**. There are four****forces**commonly recognized in particle physics: strong nuclear force, electromagnetic force, weak nuclear force, and gravitational force, in descending order of their relative strength. To that list, I would like to add gyroscopic force, as an expression of the right hand rule. The Clopton Model does not require boson particles to transmit force because the invisible STH acts directly on coupled matter. Force is the direct interaction of the space-time helix with long lived and short lived particles. The space-time helix is the answer to Einstein’s concerns about "action at a distance." Specific forces will be discussed in the sections that follow.**Like magnetism, gravity is indeed the result of warped space-time;****but in the case of gravity, the STH flow is bi-directional, or more properly, multi-directional.**Space-time is a double helix; and matter or light which is composed of the STH will follow the path laid out by the STH, not because it is the least path, but because it is the only path. Zero-rest-mass photons ride the space-time helices as modulated distortions. Space-time helices are deflected and warped by the lens effect of matter through which they pass, yielding gravity and magnetism. Light photons can be stripped from one STH and applied to another STH at a pair node.**Light can therefore be deflected near a planet or a star by free floating pair nodes (e.g., hydrogen atoms) held in the gravity of the heavenly body. Both the deflection of space-time helices, and the renormalization between STH pairs, contribute to the apparent bending of light near a star or planet.****light is a photon particle and particles mast have a mass**. The simplest of example is Einstein rings. We decided Gravity is an 'Is' and the force of Gravity is Gravitation. So OK science can measure the force - Gravitation - but it can't measure Gravity because it just 'Is'.**.**__If God is an entity so is Gravity____Thus Gravity is the same as God our at least a partner in God's doings.__^{}
Unlike the familiar ‘normal’ matter that makes up
stars, gas and dust, ‘dark’ matter is invisible but its presence can be
inferred through its gravitational influence on its surroundings. Physicists
believe that it makes up 22% of the mass of the Universe (

**]. But, despite its pervasive influence, no-one is sure what dark matter consists of and it is still a hypothetical matter but whose presence in the universe could be inferred from observed gravitational effect. Dark matter could be 85% of the total observable matter in the universe.**__compared with the 4% of normal matter and 74% comprising the most mysterious ‘dark energy’-__*dark energy*makes up a large part of the Universe, more than 70 %, and it is an enigma, perhaps the greatest in physics today
The ‘true nature’ of dark matter could be revealed by new computer modeling
work. The modeling, published in

*Science*, suggests in a universe dominated by “warm” dark matter the first stars could have formed from fragments of filaments thousands of light-years long (study abstract, commentary). “The filaments would have been about 9,000 light years long, which is about a quarter the size of the Milky Way galaxy,” according to study leader Liang Gao of Durham University in the UK. “They would have fragmented in a huge burst of star formation, a spectacular event to contemplate.”{The Great Beyond Nature.com Posted by Daniel cressey on 17^{th}Sept 2007]**Is**

The same unexplained force—dark energy—that causes the universe to fly apart at an accelerating pace is also stifling the growth of galaxy clusters, new research shows. These clusters, cloudlike swarms that are the largest accumulations of matter in the universe, grew rapidly during the first 10 billion years of cosmic time but, due to the dark energy, they can no longer continue to grow.

A giant hole”
in the universe had been discovered recently by astronomers from Minnesota . Investing an
area of the sky known as the WMAP Cold Spot, Lawrence Rudnick and his
colleagues found a very large void empty of stars, gas and even dark matter
which is nearly 6 billion trillion miles of emptiness or void .Astronomers had
long known that there are big voids in the universe, and think they can explain
them with their theories as to how large scale structures first formed. But
those theories are very hard put to
describe a void of such a huge void in
the large-scale evolution of the Universe
even by gravitational collapse

One common
view of cosmological constants is as asymptotic states. For example, the speed
of light c is (in special relativity) the maximum velocity of a massive
particle moving in ®at space-time. The gravitational constant G de nes the
limiting potential for a mass that does not form a black hole in curved
space-time. The reduced Planck constant ~ ² h=2º is the universal quantum of
action (and hence de nes a minimum uncertainty). Similarly, in string theory
there is also a fundamental unit of length (the characteristic size of the
strings). So for any physical theory we know of, there

*Cosmology with varying constants*2683should be one such constant. This view is acceptable in practice,[*Phil. Trans. R. Soc. Lond.*A (2002) on March 2, 2010 rsta.royalsocietypublishing.org] .Gravity may be also called the electromagnetic force- a force terms like nuclear forces the " in classical or is it just a distortion of space as per general theory of relativity?**How does gravity work**? " In general theory of relativity gravity is defined as the warping of the space-time due to the presence of matter and energy. This seems to imply that space/time has some form of fabric matrix. Can we not detect the gravity directly? Do we not have a gravity meter? The real answer is “No”. But why not? if it is a measurable force. The gravity is made of a particle may be called Gravitons. I assume the gravitons of all mass in our local universe, are in touch with one another. As we move farther graviton communication between masses stops. As the universe is and farther away from our local universe, at what point (distance or velocity) does expanding faster than speed of light, it seems to me there will be no graviton communication with masses outside of our local universe (distant galaxies). Personally, I like the thought of gravitons of all mass in the entire universe being in constant communication with one another. If one mass moves anywhere in the universe, all of the other mass gravitons will know its movement. ""I like it too but wonder if the gravitons communicate instantly or at C. no one has yet detected a graviton or a gravitational wave.

Is Gravity is
made of a particle that gave mass to other particle like Rupak Particle-a zero
mass particle/ or newly discovered
particle at LHC that gave mass or Higgs
particles?

Gravity should
then has ‘Speed of Gravity". There seem to be a general agreement the
speed of gravity is the speed of light, but may be less. We do not know yet. Do
any one Knows? Why then can we not measure it ? I can measure light intensity. I can measure velocity of Light as it is a particle and has wave length .I
can calculate recession velocity by red shift. I can see the spectrum of
elements detected. There are all sorts of cleaver methods of detecting what we
did not previously know.If a distant galaxy mass can be seen as visible light emitted. Why can I not
measure then gravity? Is a big question before me

**Now our Cosmos is growing for this Gravity-:**
It was not the first time that an astronomical
discovery had revolutionized our ideas, understanding about
our observable Universe. Think ! Just only a hundred years ago!, Our
Universe was then considered to be a
calm and peaceful place, no larger and nothing beyond than our own galaxy, “the
Milky Way”. The cosmological clock was ticking reliably and steadily and the
Universe was then eternal. Soon, however, a radical shift resulted changed our
believed picture. At the beginning of the 20th century, If I am not wrong
enough , one amateur American astronomer, Henrietta Swan Leavitt, could find a
way of measuring distances to far away stars then our galaxy. At the time,
women astronomers were denied access to viewing through the large telescopes,
but they were frequently employed for the cumbersome tasks of analyzing
photographic plates. Henrietta Leavitt, studied thousands of such pulsating
stars, she called them California ,
so they were able to show that almost all galaxies are moving away from us. Why ? They were then studying the so-called

*Cepheids*, and found that the brighter ones had longer pulses. Using this information, Leavitt could calculate the intrinsic brightness of Cepheids. If the distance of just one of the Cepheid stars is known, the distances to other Cepheids can be established easily– the dimmer its light, so the farther away the star-she told. A reliable standard candle was born, a first mark on the cosmic yardstick that is still used today. By making use of Cepheids, astronomers soon concluded that the “Milky Way” is just one of many billions of galaxies in the Universe. And in the 1920s, the astronomers got access to the world’s then-largest telescope Mount Wilson in*redshift (Z)*that occurs when a source of light is receding from us. What we Cardiologists and radiologists see as Doppler effect. The light’s wavelength gets stretched, and the longer the wave, the redder its colour. The conclusion then came that the galaxies are rushing away from us and from each other, and the farther away they are, the faster they move – this is known finally established as Hubble’s law.**So the Universe is growing and Expanding Rapidly**.

The coming and going of the
cosmological constant what was observed in space had already been suggested by
theoretical calculations. In 1915, The great Prof Albert Einstein N.L published his “General
Theory of Relativity”, which turned later as the foundation stone of our
understanding of the Universe ever since. The theory described ,what I did
understand whether a Universe that has to either shrink or to expand as essence
of the theory. This was a very disturbing conclusion before the physicists.
This disturbing conclusion was finally reached about a decade before the
discovery of the ever-fleeing galaxies. Not even Einstein could reconcile the
fact that the Universe was not static ( J.B Narlieker &Hoyel Steady State
Universe theory). Expansion of universe is not in fact wanted by scientists and
the concept was troublesome. So in order to stop the unwanted cosmic expansion
by then scientists, Einstein added further a constant to his equations that he
called it as”

*the cosmological constant”*. Later, Einstein considered the insertion of the cosmological constant was a big mistake by him. However, with the observations made in 1997–1998 that was awarded this year’s Nobel Prize, we can conclude that Einstein’s cosmological constant – put in for the wrong reasons – was actually brilliant. The discovery of the expanding Universe was a groundbreaking first step towards the now standard view that the Universe was created in the Big Bang almost 14 billion years ago. Both time and space began that very moment-. Ever since, the Universe has been expanding; like raisins in a raisin cake swelling in the oven, galaxies are moving away from each other due to the cosmological expansion. But where are we heading? When Einstein got rid of the cosmological constant and surrendered to the idea of a non-static Universe, he related the geometrical shape of the Universe to its fate. Is it open or closed, or is it something in between – a flat Universe?**An open Universe**is one where the gravitational force of matter is not large enough to prevent the expansion of the Universe. All matter is then diluted in an ever larger, ever colder and ever more empty space.

**In a closed Universe**, on the other hand, the gravitational force is strong enough to halt and even reverse the expansion. So the Universe eventually would stop expanding and fall back together in a hot and violent ending, a

*Big Crunch*.

**Most cosmologists, however**,

**would prefer to live in the most simple and mathematically elegant Universe: a flat one**, where the expansion is believed to decline. The Universe would thus end neither in fire nor in ice. But there is no choice. If there is a cosmological constant, the expansion will continue to accelerate, even if the Universe is flat.

**From here to eternity**

So what is it that is speeding up the
Universe?

**It is called***dark energy**and is a challenge for physics, a riddle that no one has managed to solve yet. Several ideas have been however proposed. The simplest is to reintroduce Einstein’s cosmological constant, which he once rejected. At that time, he inserted the cosmological constant as an anti-gravitational force to counter the gravitational force of matter and thus create a static Universe. Today, the cosmological constant instead appears to make the expansion of the Universe to accelerate. The cosmological constant is, of course, constant, and as such does not change over time. So dark energy becomes dominant when matter, and thus its gravity, gets diluted due to expansion of the Universe over billions of years. According to scientists, that would account for why the cosmological constant entered the scene so late in the history of the Universe, only five to six billion years ago. At about that time, the gravitational force of matter had weakened enough in relation to the cosmological constant. Until then, the expansion of the Universe had been The cosmological constant could have its source in the vacuum, empty space that, according to quantum physics, is never completely empty. Instead, the vacuum is a bubbling quantum soup where virtual particles of matter and antimatter pop in and out of existence and give rise to energy. However, the simplest estimation for the amount of dark energy does not correspond at all to the amount that has been measured in space, which is about 10*^{120}times larger (10 followed by 120 zeros). This constitutes a gigantic and still unexplained gap between theory and observation – on all the beaches of the world there are no more than 1020 (1 followed by 20 zeros) grains of sand. It may be that the dark energy is not constant after all. Perhaps it changes over time. Perhaps an unknown force field only occasionally generates dark energy. In physics there are many such force fields that collectively go by the name*quintessence*, after the Greek name for the fifth element. Quintessence could speed up the Universe, but only sometimes. That would make it impossible to foresee the fate of the Universe. Whatever dark energy is, it seems to be here to stay. It fits very well in the cosmological puzzle that physicists and astronomers have been working on for a long time. According to current consensus, about three quarters of the Universe consist of dark energy. The rest is matter. But the regular matter, the stuff that galaxies, stars, humans and flowers are made of, is only five percent of the Universe. The remaining matter is called*dark matter*and is so far hidden from us. The dark matter is yet another mystery in our largely unknown cosmos. Like dark energy, dark matter is invisible. So we know both only by their effects – one is pushing, the other one is pulling. They only have the adjective “dark” in common.
