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.

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.

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.

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.

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.
