Aether based explanation of dark matter

Before month I listed four explanations of dark matter, which are plural from AWT perspective:
  1. consequence of limited light speed spreading through expanding space-time
  2. surface tension effect of bell curve shaped gravity field
  3. application of mass-energy equivalence to Einstein field equation
  4. result of variable surface/volume ratio to energy spreading by principle of least action
But we can use even more illustrative explanation, linked to dispersion of energy by background field of CMB photons formed by gravitational waves (GWs), which manifests like weak deceleration equivalent to product of Hubble constant and speed of light. This dispersion is direct manifestation of hidden dimensions on both large scales, both small scales, because it manifests as a shielding effect of these photons at Casimir force distance scale. We can say, Casimir force is a shielding effect of GWs, whereas the Pioneer anomaly is subtle deceleration effect caused by dispersion by GWs. Both these forces results in violation of Newton law at small scales, which manifests itself by anomalous deceleration at large scales and as such it violates the equivalence principle of general relativity - it's as easy, as it is.

We can even find a direct analogy of this deceleration in our "pocket model" of observable Universe at water surface. From local perspective of every observer, whose size is evolutionary adjusted to wavelength of capillary waves (human distance scale) such surface is covered mostly by transversal waves, where the energy spreads in maximal speed from his insintric perspective, so he can interact with largest space-time possible (the speed of transversal waves is minimal from exsintric perspective, instead).

But the particle character of water environment manifests by dispersion of surface waves by tiny density fluctuations of underwater, which results into gradual change of transversal character of capillary waves into longitudinal one (i.e. into gravity waves). This dispersion decreases the speed of waves from exsintric perspective, which manifests like omni directional Universe expansion from insintric perspective or like subtle deceleration, which effectively freezes the spreading of surface waves, which can be interpreted like spreading of these waves in environment of gradually increasing density. We can observe this effect easily by splash ripples, formed by capillary waves. On the example bellow such waves are formed by bursting of bubbles at water surface, which can be interpreted like radiative decay of unstable particle in vacuum into gamma photons. By this interpretation dark matter effects, like Pioneer anomaly are related closely to the Universe expansion: for example the anomalous deceleration of Pioneer spacecraft (0.87 ± 0.13 nm/s2) is equal to product of Hubble constant and speed of light (a = Hc), which agrees well (±10% error) with value observed.



From this perspective every object is surrounded by virtual massive field which originates from massive field of virtual photons, i.e. the field of density fluctuations, which are manifesting in GWs formed by gravitons expanded by inflation and which is forming vacuum foam - and in this context it's quite natural and easily predictable effect following from AWT directly. Just the immense density of vacuum and common disbelief in Aether concept has caused, the effect of background field dispersion wasn't linked to dark matter observations and Pioneer anomaly before many years. Here's still plenty of room "at the bottom" of basic human understanding. Note that in this context the further search for GWs has no meaning, because we have observed them already like background noise of GWs detectors and their scope is limited by Casimir force scope in the same way, like scope of extradimensions and Lorentz symmetry violation at low scale.

As J.C. Cranwell (archive) pointed out, prof. Stephen Hawking has blundered by his own image... This picture comes from his book "A briefer history of time" at page 29 and it illustrates the energy wave spreading in particle environment. It's easy to see the waves getting further apart from each other as time increase, while Hawking is still claiming, the Lorentz invariance is "difficult to reconcile" with Newton theory. Of course it is, because it leads not only into Lorentz invariance, but into dark matter and expanding universe observations. This example just illustrates, how everyone sees, what he wants to see and Hawking the physmatic sees waves of constant wavelength in picture, which illustrates exactly the opposite.

Four approaches to dark matter

As J. Duffield once pointed out, people often say, gravitational anomalies are evidence for dark matter, but they aren’t. Dark matter is a hypothesis that attempts to explain the evidence. The evidence is the gravitational anomaly, instead. The dark matter phenomena can be explained in context of existing theories at least four ways, which appear nearly equivalent phenomenologically. The another approach, based on dispersion in particle field based is illustrated here:
  1. The simplest explanation of dark matter (DM) is based on AWT, by which every gravity field is a result of density gradient of Aether. At the case of massive bodies the highest density gradient exists just at the surface of massive object. This density gradient is a source of additional weak gravity field of negative curvature, which attracts and collects the particles of negative surface too, the particles of antimatter in particular - which is one of the ways, in which such interpretation of DM may be tested.



    From AWT follows, the idea of gravitational singularity of general is conceptually wrong, as every high curvature of Aether density would manifests like another source of matter density, which would balance the singularity at the center. This is a direct consequence of gradient driven reality (i.e. the fact, nature doesn't like jumps and steps).


  2. Another explanation may be based on general relativity in connection to mass-energy equivalence. We can consider again, maximal curvature of space-time of every massive object exists at the surface of this object. This curvature is equivalent to energy density of space-time, which is equivalent to mass density by E=mc^2 formula (this approach was formalized by J. Bekenstein and Rudi V. Nieuwenhove recently.) This additional mass density balances the curvature of the space-time, which has caused gravity field originally.



    Note that large space-time curvature at the surface of massive object will lead to violation of buoyancy condition, because mass/energy density may become higher here, then at the center of massive object - which would lead to undulations of space-time and indeterministic quantum mechanics behavior - so it suggests a route, how to implement quantum gravity solution, at least locally.

  3. Another model of dark matter may be based on general relativity and concept of omnidirectional Universe expansion. The Lense-Thirring effect is based on constant speed of energy spreading in curved space-time, which leads to reference frame dragging. If we introduce an omnidirectional space-time expansion, it will be pronounced the more, the more the space-time is curved already. This will gradually lead to freezing of energy spreading in expanding space-time, which will therefore move like single body from distant observer perspective. For example, Pioneer anomaly is based on acceleration, which is proportional to product of Hubble constant and speed of light. It can serve as an indicia, the limited speed of light and omnidirectional expansion of space-time itself is sufficient for explanation of dark matter behavior.

    The surface-tension model of AWT is still more intuitive here, though: we can imagine, the gravity field of galaxy behaves like single giant water droplet, the surface of which is behaving like water surface. And energy spreads always slower at the water surface, then through underwater or above the surface. It means, at surface layer of every gradient of gravity field the light or gravity spread in slower speed, then at the bulk. The space-time moves here like more dense and rigid body, which we can observe by rotational curves of individual stars at the galactic boundaries.
  4. The most abstract explanation of dark matter phenomena may be based on pure geometry of omnidirectional space-time expansion, where the volume of every area of space-time increases faster, then its surface. Because geometry of energy spreading is given by Lagrangian (which follows from diffusional Aether model on background), the energy spreading through bulk (via longitudinal waves) switches itself into surface spreading (via transversal waves) in less or more distant perspective - thus creating a new reference frame, because human creatures can consider only surface transversal waves in causal energy spreading at distance.
The problem of math models is, they become poorly conditioned, when large number of parameters or postulates is involved. As we can see, even qualitative models may lead to similar results here - so it may be difficult to distinguish between then. The increasing number of various theories becomes a brake of the intersubjective understanding of reality, after then - which isn't quite accidental here, because dark matter is a quantum gravity phenomena and a manifestation of hidden dimensions of space-time. We cannot have a formal model of gravity based on quantum mechanics, while retaining full determinism of general relativity. Mainstream physics was trapped in determinism of consecutive logics, on which formal math is based.

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.



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 dark matter

Dark matter (DM) is weak gravitational lensing phenomena, occurring mostly at the presence of another massive bodies, albeit some DM galaxies exists by the same way, like galaxies without apparent presence of DM. It was revealed by Swiss astrophysicist Fritz Zwicky of the California Institute of Technology in 1933. Currently DM has many plural interpretations / explanations, some of which are related to dark energy phenomena, which can be considered dual to DM, being observed from insintric perspective only.

The simplest explanation of dark matter (DM) is provided by concept of omnidirectional universe expansion in connection to limited speed of energy spreading. This expansion is accelerated near massive bodies, so that the photons spreading from massive bodies are occasionally freezing in expanding space-time. This concept can be extended by geometrodynamics, which explains for example the formation of dark matter rings around rotating objects (galaxies) and gravitational anomalies of satellites, passing through equatorial plane of Earth or solar system rotation. Acceleration of Pioneer anomaly supports this explanation of DM particularly well, because its value (0.87 ± 0.13 nanometers/s^2) agrees with the product of Hubble constant and speed of light at range of roughly ±10%.



Quantum gravity approach based on modified relativity provides anther explanation of DM by modification of Einstein's equations of general relativity. Because every massive object has a zero gravity field at this center, gravitational field of massive bodies exhibits it's own mass/energy density, which increases curvature of space-time at places at the inflexion point of gravity field gradient. Limited speed of light introduces a "dark energy" density gradient into every sufficiently large area of space-time filled by matter by uniform way. At the moment, when space-time curvature becomes sufficiently high (typically at the case of large scale and/or high energy density), an event horizon is formed automatically (typically at the center of large galaxies). Near surface of black holes the high mass/energy density of gravity field gradient can even lead into violation of buoyancy condition and into formation of undulating wave packet, which can be described by quantum mechanics. Therefore modified general relativity models leads to quantization of gravity and they were formalized by many theories, by Heim, Yilmaz or Beckenstein in context of MOND theory in particular.



Therefore by AWT dark matter is simply manifestation of surface tension energy of every density gradient of vacuum, which is forming gravity field of massive bodies. This surface tension behaves like weak repulsive force analogous to surface tension of tiny mercury droplets (which are repelling mutually), i.e. it decreases a action of gravity of massive body due it's increased energy density at 40+ MPsc distance scale. Surface tension phenomena are most pronounced near surface of neutron stars and black holes, where they lead into quantum wave behavior of their surface, but they manifest itself by weak repulsive force even inside of our solar system (compare the Pioneer spacecraft anomaly, Allais effect and other phenomena).

It should be noted, all these explanations are equivalent and/or dual on background, because particles of matter can be interpreted by nested curvature of spacetime by the same way, like nested quantum waves.

Recently, DM was interpreted by supersymmetry (SUSY) phenomena, too. Surface tension effects can be observed for tiny dense clusters of elementary particles, so called strangelets, which are supposed to be mediated by specific heavy boson particles, so called WIMPS. This illustrates, how surface tension phenomena at microscale can be related to surface tension at cosmic scales by AdS/CFT duality. The existence of strangelets was observed as a dimuon event during recent Fermilab experiments, because surface tension pressure stabilizes most of unstable particles against their decay (gluonium, pentaquark and quarkonium or tetraneutron can be all considered as a manifestation of supersymmetry). The risk of avalanche propagation of strangelets belongs the most significant risks of LHC experiments, because it doesn't require so high activation energy, like supercritical black hole formation.

I do not believe, dark matter is formed by WIMPS, because it forms a rings around rotating galaxies analogous to Saturn rings. These effects should disappear completely, when the galaxy rotation stop by geometrodynamics/quantum gravity models, which could falsify axion/WIMPS models of dark matter. At least I don't see any reason, why some heavy bosons should be formed in vacuum, just because galaxy is spinning. Instead of this, dark matter streaks as a whole should be considered as a "WIMPS", heavilly expanded during universe inflation.

Therefore SUSY models based on microscopic WIMPS aren't necessary for explanation of dark matter phenomena. After all, WIMPS should remain considerably stable to be able to form the dark matter streaks (which are of primordial character) and till now we didn't observe them in collider experiments. By AWT dark matter is simply area of less or more dense quantum foam, forming vacuum. It can exhibit gravitational lensing effects and it can trap massive particles into it, the antiparticles in particular. By AWT, during barygenesis an equal portions of normal matter and antimatter were formed. The antimatter has evaporated faster due its antigravity and its remnants were trapped into dark matter streaks. The similar antimatter signal - just a bit stronger - we can observe near center of galaxies, where it surrounds central black hole. Therefore DM usually consist from two parts: the cold dark matter, formed by density gradient of vacuum, and hot dark matter, formed by charged or fast moving particles.

By AWT SUSY is an emergent geometry phenomena of surface gradient and it's quite common in nature, because it manifests in all situations, where exaggerated approach or stance leads in exactly opposite / negativistic response. For example, the negativistic / dismissive stance, which follows the (re)introduction of important ideas into physics (no matter, how useful/significant they can be) can be considered as a supersymmetry phenomena, too. The general consequences of SUSY models will be discussed later in more detail.
