Do galaxies shrink with time?

Albeit Universe is expanding seemingly (Hubble 1929), the astronomers have found recently, the galaxies are actually shrinking with time. Because a true galaxy-size increase would be incompatible with standard cosmology, if not with the laws of gravity, authors indicate the presence of systematical errors in Sloan Digital Sky Survey. Albeit I do believe, this finding is actually consistent with particle dispersion model of Universe expansion, in which objects smaller then the wavelength of CMBR are expanding with time, but the objects larger then the CMBR wavelength are collapsing instead in analogy with capillary wave dispersion at the water surface.

In accordance with this model many phenomena related to red shift actually disappaer for CMBR wavelengths (CMBR photons cannot disperse with itself). Shrinking of galaxies is therefore consistent with AWT model of surface ripples dispersion at the water surface and with time symmetry of omnidirectional Universe expansion, predicted with AWT. The Universe should expand seemingly in light shorter then the wavelength of CMBR, which is known as a red shift (Hubble 1929).


In light of wavelengths larger then CMB wavelength a blue shift and attenuation of light with distance should be actually observed. The attenuation of distant radio source with distance has been already observed, too. Last July, US astronomers announced surprising results from a high-altitude balloon experiment called ARCADE-2, which had made careful measurements of the sky at radio wavelengths. The background radio emission, which is the component smoothly distributed across the whole sky, was several times brighter than anyone was expecting.

Aether Wave Theory cannot predict the absolute value of the gain observed in this moment - but it predicts, at the wavelength of CMBR this gain should be zero, which is what has been actually observed. Actually it's just a consequence of fact, for structures larger then the wavelenght of CMBR the gravity dominates over quantum effects (pressure of CMBR), so that such objects are collapsing. Because these objects are observable only with light of comparable wavelength, the Universe should appear collapsing, when being observed in radiowaves.

Regarding blue shift of radiowave source, it has been observed possibly, too as a Pioneer maser anomaly (compare the LaViolette's blueshifting prediction). Blue shift is notoriously difficult to observe, because of lack or reliable reference sources of known frequency (hydrogen vibration spectra of remote sources are absorbed heavily with interstellar gas). But some man-made objects are already remote enough to observe blueshift with artificial sources of radiowaves.

It means, the time arrow is actually violated, our Universe doesn't travel through time in one direction. One half of Universe expands due the pressure of radiation and its entropy increases. The second part (this one larger then ~2 mm) collapses with its gravity instead and its entropy goes down.

Is dark matter of large gallaxies supersymmetric to black holes?

This post is a reaction to recent NS article "Missing dark matter mystery in small galaxies". It's well known, large galaxies and galactic clusters are relatively abundant to dark matter with compare the smaller ones. This finding could have certain meaning in AWT cosmology, in which large gallaxies were formed by evaporation of central black holes, whereas smaller ones were formed rather by accretion (i.e. by classical mechanism with respect to contemporary cosmology). Another ideas presented in connection with this model  was dark star origin of gallaxies and the shielding effect of dark matter. This effect is understandable with respect to AWT mechanism, because of large content of antimatter considered in dark matter, which could have antigravity action at large distances. Presence of heavily ionized atom nuclei trapped makes dark matter detectable by X-ray telescopes, like Chandra.



It would mean, dark matter is in fact super-symmetric effect of black holes inside of galaxies. Without presence of central black holes the galaxies cannot contain material particles around it, because of no evaporation. This idea could have some meaning in holographic theory of Universe, too. This could explain both absence of dark matter outside, both black holes outside of small galaxies. 


But the whole subject is still quite speculative in this moment and additional observational data are required. Recently Hubble has found another evidence of dark matter presence near small galaxies. This study demonstrated, that the low-velocities of stars observed around dwarf galaxies are infact compatible with galaxy formation in dark-matter haloes. Stellar orbits in the outer regions of the resulting elliptical are very elongated, which can explain the observed velocities even in the presence of large amounts of dark matter.

AWT and Big Bang theory.

In AWT the relevance of Big Bang theory is closely related to the concept of "Observable universe" and the "edge of observable space-time", which depends (as everything in AWT) on duality between insintric and exsintric perspective. According to the theory of cosmic inflation and its founder, Alan Guth, the entire universe could be (at least) 1023 to 1026 times as large as the observable universe, which roughly correspond the speed of gravitational waves propagation through observable Universe.

From insintric perspective we can apply principle "Similia simillibus observatur" (only things of similar nature can interact mutually in observation) - so we can consider, Universe is composed of many different combinations of Aether states, whereas we are composed from limited number of such states, being only part of Universe. If the probability of occurrence of our particular combination of states decreases with distance, then the probability, we could interact with the rest of Universe decreases with distance as well. Therefore we can observe "edge of space", but we cannot reach it, because we would evaporate first in unfriendly ("hot") vacuum around it.

This is basically anthropocentric "black hole model" of Universe formation, which introduces evolutionary absolute reference frame: if we evolved in certain part of Universe, it's because, the conditions were relatively favorable for us here and if we would travel outside of from this pretty place, we can only face problems there. It's evident, every surface of matter, like hot star or black hole forms such natural boundary of observable Universe for us and it's even possible, matter in remote galaxies evolved into exotic forms of matter, which would annihilate (i.e. explode) less or more completely in direct contact with us.

Exsintric perspective of Universe is less real but more optimistic and it has no apparent boundary: the probability of our particular combination of states decreases, but the number of new combinations increases even faster with distance, so we can always find a some friendly combinations of states there. Until space-time is formed by "friendly combinations" of states, it means, we are observing free space, so we can travel through it without apparent limit and danger - but there's no certainty, we aren't just moving in circles during this, because concept of distance and free space is tautological here. From AWT follows, real appearance of Universe is a formed by nested foam mixture of insintric and exsintric perspective: there are many places, where we can finish in our travel prematurely (planets, stars and black holes) - but in general Universe appears as an empty free space due the Olbers paradox.

Olbers paradox is a consequence of Cosmic Microwave Background Radiation (CMBR), which is behaving like subtle density fluctuations of space (i.e. gravitational waves) violating Lorentz and Poincaré symmetry, which results in gradual dispersion of light into hidden dimensions of space-time in analogy to spreading of splash ripples at the water surface. This analogy follows directly from concept of dense Aether of AWT, but it's not completely new, as it was proposed independently by James Clifford Cranwell between years 2001 and 2007. Mr. Cranvell's concept was bright, but it illustrates clearly, without active (self)promotion no idea has chance to become famous in fast expanding Internet space, if it has no immediate usage for sufficiently large group of people - no matter how brilliant it is. Unfortunately Mr. Cranvell didn't recognize the power of dense Aether concept as such and he turned his attention to derived concept of omni-directional expansion of space-time, which is apparently more abstract and it can be interpreted in dual way by AWT.



For observer of transversal waves at water surface the speed of ripples increases fast with distance (they change into gravitational waves), which can be interpreted from the perspective of this observer as an omni-directional expansion of space-time with distance. The same situation is relevant for observation of distant parts of our Universe via light waves.

At sufficient distance from observer wavelength of transversal waves ceases to zero, which can be interpreted by this observer as an initial singularity of Big Bang theory, or like surface (event horizon) of black hole (cosmic void), which observer occurs. From AWT follows, these models may be of certain relevance from perspective of numerical models - but they're all invariant to observer localtion. We can compare this situation to observation of landscape under haze - visibility scope will be limited by dispersion of light, but it will move accordingly to actual location of observer.

Because this effect is apparently nonlinear, we can explain dark energy phenomena in the same way. From outside we can see, these ripples get more dense gradually, until they disperse completely. The same effect appears at cosmological scale like slowing the speed of light in dense environment, surrounding every source of radiation, so it can be used for explanation of cold portion of dark matter and its connection to Hubble constant as well. Whereas from perspective of insintric observer, Universe appears like we would travel through density gradient, forming event horizon of black hole (some string theorists are talking about "throat of dark brane" in this connection).

From more general view of AWT this evolution is just an illusion, which follows from insintric observational perspective inside of fractal Aether foam, because we are connecting the observation of microscopic scale with the future of Universe expansion, the past with observation of vast cosmic space. Evolution of large objects is the more slow, the larger these objects are and Universe as a whole doesn't really evolve at general scale. The only question is, whether such general perspective is achievable for human creatures by experiments, i.e. by different way then just by pure human imagination.

Nevertheless, from AWT follows, Big Bang theory would suffer by fundamental problems in near future, which are of both of practical, both philosophical (ontological) nature. Observational problem with Big Bang is, we can observe well developed and separated galaxies in the Hubble ultra-deep field, when the Universe was just 2 - 3 billions of years old. And Milky Way galaxy is more then ten billions of years old, so that these ancient galaxies have not enough time to separate and develop. This conclusion was supported by recent observation of well developed galaxies (with very low speed of star formation) in ultradeep field of refurbished Hubble telescope in contrary to standard cosmological model based on Big Bang theory, in which star formation couldn't occur during dark era of universe formation.

Ontological problem of Big Bang theory is, it brings more questions, then answers - not saying about the problem of initial singularity. It can explain red shift, but it cannot explain dark energy. And it requires inflation, which appears like ad-hoced concept from contemporary perspective, although it can be interpreted as a phase transition of Aether easily and it can be reconciled with ekpyrotic cosmology in such way. But from general perspective it seems, all these models are just plural result of dispersive nature of Aether environment. The analogy of Universe evolution with stellar and galactic evolution is just apparent, because from very general and remote perspective Universe behaves like atemporal stuff (perceived mass/energy density of Aether increases ad infinitum).

Is dark matter composed of antimatter?

The origin of matter-antimatter asymmetry was a struggling problem of mainstream physics and cosmology for many years. By AWT antimatter never disappear from observable Universe, it was only finely divided (evaporated) into streaks of dark matter. These streaks are surrounding all massive bodies, including galaxies and stars, so that the concentration of antiparticles is especially easy to detect around black holes at the centers of most large galaxies. This prediction was presented a two years before and now recent ATIC and PAMELA observations seems to support it, while interpreting the source as a result of WIMPS annihilation. This is particularly because contemporary particle physics is quite desperate for funding. Guessing that dark matter consists of exotic particles may mean more funding to search for such particles.


AWT explanation doesn't consider WIMPS mechanism though, because WIMPS are supersymmetric bosons mediating surface tensions forces of strangeletes, i.e. large dense clusters of particles, which are supposed to form dark matter here. Such clusters would be of primordial origin, i.e. something like microscopic black holes in the S1/Z2 Randall - Sundrum (RS) braneworld model, which currently belongs into unverified hypothesis, as the only stable strangelets-like particles known so far are the atom nuclei. It's highly improbable, swarms of such thingies would be responsible for observed dark matter effects like gravitational lensing or Pioneer anomaly and even if they would exist, it's not necessary to consider their bosons (i.e. WIMPS) as the main source of dark matter gravitation - because no WIMP can exist standalone without its superpartner. Such explanation therefore just illustrates deep conceptual confusion of mainstream physics, which is overspecialized, so it cannot confront & reconcile inconsistently labeled ideas coming from various areas of physics mutually.

Instead of this, AWT explains mechanism of primordial origin of antimatter more naturally. We can consider black holes as a dense mixture of hot matter and antimatter in the form of graviton foam, analogous to foam of density fluctuations, formed briefly after condensation of supercritical fluid. In this foam particles are foam excitations are tied to inner surface gradients of foam bubbles, while the antiparticles are formed by outer surface of membranes (string theory uses a concept of string loops attached to branes, instead). But these particle gradients are never quite equivalent: the inner gradient are always of smaller diameter and higher curvature, therefore they're more stable, then the outer surface gradients. This is a general consequence of fact, we are always smaller, then the observable Universe generation, despite how far we can observe it, so that the particles forming environment are always of opposite chirality with compare to particles forming an objects in it.
Currently quantum foam forming vacuum is expanded heavily and its bubbles are formed by very thin walls, so here's rather subtle difference between particles and antiparticles behavior, as characterized by so called CP symmetry violation - but at the beginning of universe the situation was completely different. Graviton foam was very dense there and it was formed by rather spherical bubbles with thick walls. Inside of such foam the particles of antimatter were transformed into particles of matter readily, by the same way, like small bubbles in foam are collapsing on behalf of those larger ones or small flakes of snow sublime on behalf of large crystals, thus making snow "grainy". If such mixture would cool slowly, it would transform completely back into radiation again - but we were lucky: due the fast expansion of space-time during inflation era a subtle portion of matter and antimatter particles was left unreacted, so we are still here, being surrounded by voluminous streaks of dark matter composed of sparse unreacted particles of matter and antimatter separated by EM charge interactions against gravitational collapse (note the connection of AWT to H. Alfven's ambiplasma cosmology here.).


Because their negative curvature, the antiparticles tends to move toward gravity field so it separates from resulting condensate of matter and surrounds it by the same way, like particles forming the outer gradient of soap bubble membrane are surrounding those, which are forming inner surface of it. Standard model in combination with inflationary cosmology provides an mainstream explanation of this evolution. At the very beginning of Universe was very dense, so that weak nuclear force responsible for matter-antimatter interaction was a large distance interaction here. Because as we know, the matter annihilate with antimatter in direct contact, i.e. whenever weak interaction takes place, matter was annihilated with matter readily. But because the Universe expanded fast during inflation, weak nuclear force has become a short distance interaction (and it remained until now) - so that subtle portion of antimatter particles remained separated from the rest of matter safely.

The similar phenomena occurs during accretion of matter and during explosions of collapsars, i.e. the quasars, neutron and quark stars. While matter and antimatter annihilate in direct contact under formation of gamma radiation (i.e. EM field), in abundance of strong electromagnetic or gravitational field this process can be reversed under so called matter-antimatter pairs production. Strong magnetic field causes a separation of resulting particles and antiparticles near magnetars and spinning black hole, whereas gravity field is less effective in doing this in general, but it can separate even particles, which are differing just by their lepton charge, not only EM charge. In general, massive particles are attracted to inner part of gravity field gradient of positive curvature, whereas antiparticles were attracted by field gradient after its inflexion point, i.e. by its negative curvature. This resulted into separation of matter and antimatter particles. Note that the same mechanism (only applied to different dimensional scale) could explain chirality distribution, observed in nearby galaxies along streaks of dark matter and polarization of CMB.


While such process appears completely different from perspective of classical physics, it has a number of analogies in it, in fact, because it's driven by curvature of surface gradients in all cases. During fast condensation a mixture of water droplets of different sizes appears. But the smaller droplets have always a higher tension of vapor, so they're evaporating of behalf of these larger ones. When such condensation occurs as a consequence of fast vapor expansion (for example in Wilson cloud chamber expanded by piston), then the smaller droplets travels at the large distance from center of expansion, until they don't evaporate completely. After then they're forming an areas of more saturated vapor surrounding more "lucky" droplets, which have condensed at rest and which tends to evaporate. By AWT the dimensional scale, separating the matter evaporation from condensation roughly corresponds the human dimensional scale and wavelength of CMB photons, as it brings the highest complexity into Universe evolution. Particles smaller then CMB photons would condense into particles of matter, whereas the larger particle would expand into streaks of dark matter. From certain point of view antimatter is livin in inverse/reciprocal time arrow inside of observable Universe - it evaporates while the normal matter condenses, which is the reason, why the antimatter is finely dispersed over whole Universe.


The above example can be generalized in terms of unsteady-state thermodynamics, as described by Le Chattelier principle. For example, when we cool sooting candle flame by blowing of cold wind or by insertion of cold teaspoon, we can obtain a thin layer of soot. In this analogy, the flame corresponds the collapsar radiating an energy and the soot and oxygen are analogy of common matter and antimatter. As we know, these particles of these components reacts readily in mutual contact (i.e. they're "annihilate") - but when separated fast from flame by cooling of mixture or by adiabatic expansion of environment, they can remain intact and fast cooling freezes this metastable equilibrium on behalf of presence of the original components.

By AWT we can find an analogies to matter-antimatter separation even in biological and social evolution, where exist so called division of labor between different molecules and sexes, which are exhibiting a sort of chirality, too. AWT model explains, why this chirality was important during life formation in liposomes at human scale. Currently energy density of society is relatively high, which enables a high level of emancipation. But at the very beginning of human society the survival / fitness of community has depended on division of labor heavily, so today men are traveling for jobs at distance, while women are working near their homes - although they're not required to do so. But despite of low level of symmetry violation the complete exchange of male/female roles would lead to annihilation of social structures (i.e. family condensate in particular) by the same way, like switching of role left-handed proteins and right-handed sugars would lead to death of most of living organisms immediately. These analogies help us to understand, how deeply the chirality is working inside of our Universe at different dimensional scales.

AWT considers the existence of chirality as a byproduct of Universe inflation, i.e. the consequence of its fast cooling after brane collision, but such process occurs analogously at most dimensional scales, for example during collapse of stars and black holes, just in less or more pronounced way. The concept of omnidirectional Universe expansion enables to describe this process in terms of spatialized time, i.e. as a process of nonuniform propagation of transversal and longitudinal energy waves through hyperspace, but removal of space-time symmetry prohibits us in using of many temporal analogies, which could simplify the deeper understanding of this unsteady process.

We can just ask, why astronomers, who are looking for missing antimatter in Universe from the very beginning of BigBang theory (Lemaître 1931) didn't considered the posibility, dark matter may be composed of antimatter from the very beginning of dark matter observation (Fritz Zwicky, 1933). In another way - why publicity should pay scientists for seventy years of research of another explanations, if they ignore these most simplest one? This situation isn't very new here and it just illustrates, science needs a thorough public control by the same way, like every other branch of society. Arrogance of mainstream science proponents isn't in place here, as it often covers the incompetence.

AWT and human scale

By AWT the Universe appears like being formed by infinitely nested field of density fluctuations of Aether. The human brain is one of such fluctuation, due its large time scale it can interact/observe a huge portion of space-time both into past of Universe expansion (the cosmic scale), both into future of it (the Planck scale). Because of symmetry of mutual interaction, human scale appears exactly at the middle of observable space-time scale. The human scale is defined by the average size of neurons inside of human brain (lowest entropy observable inside of our Universe generation) or by wavelength of cosmic microwave background radiation (CMB) (about 1.7 cm), which is apparently chaotic (highest entropy density observable). Under furthersome conditions, the violation of Lorentz symmetry can be observed by naked eye as a Brownian motion at Planck scale or like gravity lensing at cosmic scale - due CPT symmetry violation the Planck scale appears more close to human scale, then the cosmic one.

The wavelength 1.7 cm is invariant with respect to AdS-CFT duality, because it corresponds the wavelength, when the character of energy spreading changes from longitudinal waves to transversal one. From AWT perspective the CMB corresponds the capillary waves at water surface, which are spreading along it by the lowest speed at wavelength of 1.73 cm from exsintric perspective, enabling to interact with as large space-time, as possible and allowing the most advanced evolution of matter inside it. Classical quantum mechanics cannot handle gravity (phenomena) at all and quantum noise blurs in CMB noise above human scale by the same way, like relativity is limited by CMB noise (GZK limit, CMB Doppler anisotropy, etc.) in its predictions.

From cosmological perspective, the wavelength of CMB (1,7 cm) corresponds the outer diameter of Universe or the wavelength of Hawking radiation of tiny black hole, whose lifespan corresponds the age of our Universe generation (13.7 GYrs) - so we can say, the CMB is Hawking radiation of the black hole, which we are living in, i.e. red-shifted radiation of most distant quasars. The foamy character of energy spreading enables to see the event horizons of our Universe both from inside, both from outside via CMB radiation (i.e. the event horizons of most distant quasars observable). The larger (gravitational waves) or shorter waves (gamma radiation) are of limited scope with compare to CMB due the dispersion (GZK limit) in analogy to capillary waves spreading at water surface (compare the celerity curve bellow). The energy density of 3D space-time (roughly given by third power of Planck constant, i.e. 1oE+96 J/m3) corresponds the mass density of black hole, which is forming it.


From AWT follows, every Aether fluctuation of diameter bellow 1.7 cm will dissolve into photons and neutrinos, while the larger objects will collapse into heavier objects and evaporate by the same way. The black holes of diameter bellow 1.7 cm can evaporate via Hawking radiation during observable Universe lifespan, while these larger ones will evaporate by accretion radiation - so we can say, such objects are the most stable objects inside of observable Universe generation and accretion radiation is AdS-CFT dual to Hawking's one (massive objects bellow 1.7 scale falling into event horizon would appear like tiny quantum fluctuations from distant perspective outside of black hole due the immense space-time compactification around it). The density of largest black holes existing inside of observable Universe (with 10+9 times the mass of the sun, which has a radius of event horizon about 109 km) should be comparable with human scale (1 kg per dm3).

Curvature instability is scale invariant. During Big Bang event, all particles were formed by supersymmetric gravitons, the average size of which corresponded the wavelength of CMB photons. During universe evolution the larger gravitons condensed into particles and objects of observable matter, while the smaller fluctuations have evaporated into antiparticles of matter, which were dispersed by its repulsive gravity into clouds of dark matter, surrounding the objects of normal matter. The same criterion can be applied for planet and planetoids formation or even for predators-prey relationship of biosphere. Only pieces larger then some 1.7 cm can serve as a nuclei for accretion and subsequent gravitational growth, or they would become dispersed by radiation pressure of CMB photons. The smaller pieces of matter tends to condense as a whole in large clusters, instead (large means > 1.7 cm).


From AWT follows, the size of photons is given by interference of light wave with graviton background of Planck length scale, forming the quantum foam background of universe. From interference condition follows, the size of wave packet is equal to their wavelength size exactly at the 1.7 cm scale, which effectivelly means, microwave photons are serving both like particles, both like waves, i.e. by the same way, like gravitons in previous generation of Universe, expanded during inflation or like graviton waves in future generation of Universe before its gravitational collapse. The photons of larger wavelength cannot exist, because they tend to condense spontaneously with these smaller ones into solitons of negative rest mass (axions, or so called tachyon condensate).

Even tiny droplets and bubbles in mixtures tends to shrink and evaporate bellow 1.7 cm scale, while larger droplets and bubbles expands and fragments. The least stable droplets of 1,7 cm diameter (liposomes) could started the evolution of life at shallow places of ancient oceans (i.e. inside of multiphase environment of the largest possible complexity). The repeated breakdown by surf waves enabled them to compete for collection and/or (later) production of surfactants, which enabled them to remain as stable, as possible. Whole evolutionary process lasted whole Universe age, because AWT makes no conceptual difference between evolution of inorganic matter and organic life. Therefore it's nothing very strange, the quantum nature and size of neural standing waves corresponds the size of Universe scope, perceivable just by these waves (i.e. quantum gravity standing wave, forming the observable Universe generation). The increasing density of Universe resulting from vacuum foam collapse corresponds the expansion of the scope of human consiusness, capable to comprehend an increasing space-time portion of Aether chaos complexity during time.

The anthropocentric question, whether 1.7 cm distance scale is adjusted by evolution or it just enables the best visibility of Universe remains a tautology by Aether theory, because from AWT follows, every object which is product of less or more long term evolution has tendency to remain adapted to its environment and vice-versa. The scope of observable Universe always depends on entropy density of observer (i.e. number of time events/mutations involved) - the primitive organisms can see their Universe smaller, the more intelligent larger accordingly.

Big Bang and Olbers paradox

Classical explanation of Olber's paradox is, the dark matter between stars prohibits us to see the light of stars filling whole night sky. Such explanation is relevant for most distant active gallactic nuclei (AGN), observable only in infrared due the dust cover (so called the spherical dust galaxies revealed by Spitzer infrared telescope).

If we consider the finite speed of light, then the fact night sky is black would mean, the Universe can be larger, then the finite speed of light allows. Big Bang theory considers, light emanated by primordial matter was of very high frequency, therefore it can be observed as a CMB by now. If we consider cosmological principle of uniform isotropic universe, then the presence of CMB supports rather idea of infinitely large Universe, from which only the visible portion of light can be perceived. Radiofrequency part of CMB is forming a thermal noise of matter at the zero temperature (ZPE). As we can see, Olber's paradox cannot be used as an evidence of finite Universe and Big Bang theory reliably. AWT is assuming, observable Universe generation appears like rather common AGN from outer perspective, therefore our Universe doesn't differs very much from another quasars (white holes), which are observable inside of our Universe by Copernican principle.

Anthropic principle and Universe evolution

By AWT the evolution of living matter is just a continuation of evolution of inorganic matter, while the Aether foam concept is most pronounced here: the neural net is an analogy to tissue foam, which is analogy to liposome foam, which is an analogy to mechanic foam at the fluid-gas interface, which is just another level of foam of water clusters, atom orbitas and string fluid inside of atom nuclei and vacuum itself (quantum graviton foam). This insight was reformulated recently on background of thermodynamics.

By AWT the quantum foam is of natural evolutionary character, because the density fluctuations of foam are behaving like tiny optical lenses, they're focusing energy waves into itself like food while competing mutually, so that just the most stable and dense fluctuations can survive from long perspective. From this perspective whole Universe appears to be of the same character, being formed by giant fluctuation of Aether foam, evolved during long Universe history into its present state. The concept of Universe evolution was disputed in notion of expyrotic and multiverse bubble cosmology, Darwinian aspects of Universe evolution were popularized by Lee Smolin in his "Theory of Cosmological Natural Selection" on background of causal evolution of spin networks.

By AWT the concept of Universe evolution is dual to the anthropic principle, the fine-tuned Universe principle in particular by which the Universe appears as the best place adopted for human life evolution due the especially well balanced combination of physical constants. As such it serves as on of main arguments for creationism, which is considered as a dual theory to evolution by AWT. Deeper insight learn us, every product of long term evolution will consider its environment well balanced and nothing very special is about it.

For example sharks are so well adopted to the life at the bottom of ocean due their long term evolution, so they can start to believe in "selachimorphacentric" principle easily: they're condemned to believe in "Big Shark" divinity, which has created the bottom of oceans especially well balanced and suited to shark needs. Surprisingly enough, such trivial insight wasn't never mentioned in connection to anthropic principle by my information, while it's quite apparent and it renders whole anthropic principle a bit redundant on behalf of evolutionary theory by my opinion.

Is Earth at the heart of a giant cosmic void?

This post is a reaction to the NewScientist article of the same name. By AWT the Universe is behaving like interior of very dense star, where the energy spreads along surfaces of foamy density fluctuations, similar to those, which we can observe during condensation of every dense particle system. Now we can start to think:

"If such environment would be completely homogeneous, could we see something from it?"

Of course not - our ability to see some matter or phenomena is given by the fact, the randomness of system is violated in certain space and/or time. For example, we can see a laser ray in atmosphere just because such atmosphere is a bit inhomogeneous. The laser ray on the picture bellow is FASOR used at the Starfire Optical Range for LIDAR and laser guide star experiments is tuned to the sodium D2a line and used to excite sodium atoms in the upper atmosphere. In vacuum we could never see some ray from outside.

http://superstruny.aspweb.cz/images/fyzika/astronomy/sodium_laser.gif

But the very same reason, which enables us to see the stars, red shift or expansion of Universe means, it's related to some dispersion and divergence in less or more distant perspective. It's tic for tat: if you want to see at least something predictable and regular, such regularity and symmetry would be always broken in less or more distant perspective (compare the geometry of density blog interactions, as described herein). It means, when we can see a light of distant stars, it's just because the vacuum contains some inhomogeneities, which can serve for causal energy spreading in transversal waves. But just these inhomogeneities are the very reason, why such causality is violated in less or more distant perspective, because you cannot separate causal fluctuations of vacuum from these random ones.

http://superstruny.aspweb.cz/images/fyzika/astronomy/universe_horn.gif
Therefore the light of distant stars appears reddish, and the speed of this redness is accelerated with distance (and the speed of its speed as well). This is because the same reason, which serves for light spreading is the reason of its dispersion, which we can perceive as a red shift and expansion of space-time. We can observe it as a omni-directional Universe expansion. And this expansion even proceeds the faster, the farther is the distance, from which we are observing it. We are calling it a dark energy. By AWT our ability to see at least something is always connected with nonlinearity of this observation in less or more global perspective. Of course, this cannot serve as an evidence of geocentric model, because it's merely an observational illusion, which is relative to each observer in Universe. We can compare to keeping of lantern inside of dense fog: after then our Universe would appear like spherical zone of iluminated fog symmetric to our location, no matter when we are staying right now.

In fact, we should observe the very same effects even at the water surface, when we would use the surface water waves as the only source of information about our neigbourhood, because water surface is never quite homogeneous, as it always contains a Brownian noise fluctuations. But these density fluctuations cannot be seen from surface wave perspective directly, they would appear like quantum chaos instead by deforming the images of other objects at proximity.

Dual view to Universe expansion by AWT

By AWT both volume of Universe, both dimensionality of that volume is virtually infinite. But the speed of energy spreading is limited and the energy density of light, coming from higher dimensions is limited as well (in fact, we are still looking for gravitational waves). We can compare this situation to the illumination of foggy street by lantern. The street can huge, but we can see just a limited illuminated spherical part from it because of dispersion: the farther the light source is, the more the street appears dim and shifted toward longer wavelengths. At the case of Universe observation, we are interpreting this red shift as a result of omni-directional Universe/space-time expansion). By such way, at the certain distance the light intensity will cease to zero, we will reach the physical limit of the observability of Riemann's Universe sphere. This doesn't mean, the Universe has some limit at the surface of sphere - we just cannot see it by using of light in causal way anymore.

Due the symmetry of time arrow, we are limited by the same way not in cosmic scale, but in micro-scale as well. At the Planck scale the dispersion will take place and the neighborhood will disappear in quantum chaos. Due the Universe expansion we can interpret every look into distance as a look into past, while every observation of microscopic scale we can interpret as a look into distant future of our Universe. And both these views are principally limited not by the physical size of Universe, but by character of causal energy spreading. We are using a transversal light waves for collection of information, but at the distant scale the casual Universe character becomes dim a and blurry because of prevailing longitudinal character of energy waves.

To understand these connection by illustrative way, we can use a simple surface water model. The water surface is serving as a local space-time for surface wave spreading in transversal waves by the same way, like the vacuum is serving for spreading in transversal light waves. But this transversal character is violated by the dispersion of underwater inhomogeneities the more, the more the scale becomes different from characteristic wavelength of surface wave spreading, which has character of material constant.


As we can see from so called celerity curve, the surface waves are spreading by different speed, which depends on their wavelengths: here exists some minimum, during which the transversal character of surface waves becomes most pronounced and the waves will spread by slowest speed - the waves of 1,27 cm in wavelength are called capillary waves and they're not influenced by dispersion very much. From perspective of hypothetical creatures, living at the water surface this surface would appear most large at this wavelength (which corresponds the wavelength of CMB, by the way) - because energy spreads by the lowest speed here.

Because the light dispersion increases both toward lower, both higher wavelengths, our Universe would appear smaller when observed with the light of these wavelengths. We can observe it as a so called GZK limit at the case of gamma rays, for example. This is a natural consequence of the dispersive nature of vacuum, whenever the wavelength of light will shift from the optimal frequency by celerity curve. We should realize, we cannot detect the change in light speed directly in local measurements, because we are using the very same waves both for time, both for space measurements, so that the light speed will remain always very invariant. What we can observe directly is just a red shift in the characteristic spectrum frequencies of distant stars and galaxies.

The main problem in understanding of all these connections remains the fact, the people are observing the wave spreading from nonlocal, outer perspective, i.e. they're using the another, faster waves in observation and description of wave spreading phenomena. For example, when observing a surface wave spreading by using of light waves, the Galileo transform will take the place and everything appears normal from classical physics perspective, i.e. no relativity is here.
While at the vacuum we are used to observe the light wave spreading just by light waves, simply because we haven't no another, faster waves available. This introduces a new observational perspective, in which the relativistic effects are manifesting. The whole relativity is simply a result of classical physics of wave spreading, as being observed from perspective of these waves itself - that's all.

In AWT this local perspective is called an internal perspective, because the observer remains involved in experiment. For example, we can observe a gravitational lensing both from internal perspective, when the space-time becomes curved and the light path remains straight, both from outer perspective, when the space-time remains flat and the light path becomes curved.



It's rather consequence of widespread belief in power of relativity, both these perspective are interpreted by relativity theory, while just the internal perspective remains fully consistent with it, in fact. The outer perspective always violates the Lorentz invariance, because the speed of light spreading in vacuum cannot remain constant, or the light wouldn't spread by curved path. The gravitational lensing, as we are observing it usually is rather sort of quantum mechanics phenomena, the quantum gravity in particular. We cannot prove the curvature of space-time at distance, everything, what we can observe is curved path of light, so that the interpretation of gravitational lensing by relativity is rather sort of conjecture from strictly causal perspective.

AWT, inflation and brane cosmology

AWT reconciles the brane cosmology (so called ekpyrotic Universe) with Guth's concept of cosmic inflation and Big Bang cosmology by modeling of condensation of matter inside of dense star, collapsing by it's own gravity by assumption, the gravitational collapse has started from many places at the same moment. The spherical zones of condensing vacuum has intersect mutually under formation of foamy structure of metastable shock waves, similar to condensation of supercooled liquid or supersaturated solution:


As the result, observable matter has condensed both into sparse particle clouds, both into dense overheated droplets of metastable matter, so called quasars, sitting in the nodes of resulting foamy structure of dark matter. The finely divided matter has formed small galaxies and stellar clusters without central black holes by mechanism of gradual gravitational collapse, which doesn't differ significantly from contemporary mainstream cosmology. But the formation of large galaxies was completely different by AWT.


After releasing of pressure, quasars have started to evaporate their excessive matter into radiation, which has condensed partially near quasars, whenever the intensity of gravitational field has decreased bellow certain value. The quasars were surrounded by particles of matter and antimatter, which have exchanged their mass by radiation on behalf of observable matter. The resulting particles were formed by atom nuclei up to silicon, which recombined with electrons under formation of heavy clouds of dense dust, surrounding the active galactic nuclei. The particles of dust were kept at the safe distance by radiative pressure of central quasars inside it. The newly formed galaxies were of spherical shape and they were only slightly radiative because of strong light absorption by dust particles.

The central quasars were formed by "naked singularities", i.e. neutrino stars without event horizons. When the excessive mass of quasar has evaporated, the quasars were covered by event horizons with exception of polar jets (compare the black hole theory in previous post). This symmetry violation has given the flat shape and rotation to resulting galaxies, which were tossed like pizza dough. At the very end, the black holes rested at the centers of galaxies as a cold remnants of quasars with weak antimatter signal around it and the spherical shape of galaxies was restored gradually by tidal forces.


The dual AWT cosmology is based on understanding, the observable matter is metastable phase in contact with vacuum and it has tendency to evaporate at elevated temperature and/or gravity field intensity. Therefore the matter must be formed by another mechanism and the black holes can play an active role in it. In addition, a recent observation supports the above model by presence of giant black holes and sparsely distributed, but well developed galaxies composed of heavy elements even at the most distant/old parts of Universe. This model considers upper limit of giant black holes, above which the matter is radiated, not swallowed by black holes. This upper limit follows from modified theory of gravity, the quantum gravity in particular, as predicted by AWT.

Remark 1: This idea was originally presented before three years and it was recently disputed in Nature News and NewScientist article, so it belongs into testable predictions of AWT, because we can observe remnants of this process both by stars formation near black hole inside of our gallaxy, both by galaxies formation near distant qausars.

Remark 2: This idea has relevance to so called shock wave cosmology of black holes, as proposed by J. Smoller and B. Temple [PNAS, 2002]. I hope, these connections will make whole stuff more interesting for the rest of cosmologists.

Remark 3: While cosmologists are aware of the fact, the brane collisions should left some traces on CMB background, it seems, nobody tried to connect the foamy structure of dark matter with is concept of penetrating branes - supposedly because nobody has considered their material nature and because ekpyrotic cosmology is illustrated quite abstract and meaningless way.
Remark 4: Anonymous barkster user has noted a simmilarity of black hole jets with jets formed by collision of water (mem)branes. This connection has really some relevance here, as by AWT black hole jets are temporal artifacts too and it can be interpreted as a product of spontaneous symmetry breaking of event horizon.
