    The dark energy appears to be a trivial consequence of the spatially uniform(!) universe expansion. If we’ll observe the light/gravity spreading across some large distant galaxy, the spreading of light from the center to the boundary will take some time.

    During this the space-time will expand a bit, so that the light is spreading more and more slowly, when leaving the galaxy. As the result, the border of galaxy will appear to move as more compact object then the center by the same way, like the MOND theory predicts. It means, the uniformity of space-time expansion leads to the acceleration effect (…and the acceleration of acceleration, etc…) of the Universe expansion undeniably.

    This basically means, the Universe expansion will always appear nonlinear when observed non-locally, which in turn can lead to the black hole event horizons, dark matter streaks and vortexes, polarization of CMB and other refraction phenomena, as being observed through large areas of uniformly expanding space.

    The gravity is related to the uniformity of space-time expansion as well. It can be understood by many ways, I’ll choose one connection, which isn’t generally so obvious here.

    Well, as probably many people know, the geometrodynamic theory of brilliant J.A.Wheeler didn’t passed the scrutiny, because it leads to the collapse of geons into singularities undeniably. The geometrodynamics is general relativity based theory and the geons are supposed to be a model of elementary particles, composed of gravitational waves.

    When comparing the relativity theory with quantum mechanics, we can see, the quantum mechanics is facing exactly the reciprocal (dual) problem here: the model of free particle as described by classical Schrödinger equation leads to the dissolving of the quantum wave of the particle into vacuum undeniably.

    As we know, the quantum wave of particles doesn’t dissolve in vacuum, because of the potential wall of particle gravity, which literally “keeps the wave packet together”. Unfortunately, the gravity phenomena cannot be derived from quantum mechanics by any way, but it follows from relativity theory.

    Therefore the application of relativity to quantum mechanics can solve this problem at least partially and it leads to the quasi-stable solution of Dirac’s equation (…and the spin phenomena and many other features, described by different quantum field theories extensively).

    By Aether Wave Theory the Universe can be observed as a gradually collapsing black hole, which gets more dense gradually, so that the space-time expansion can compensate the collapse of geons particles by the same way, like the gravity can compensate the expansion of quantum wave packets – well, at least locally. Please note, that the gravitational lensing – as predicted by relativity theory – can be considered as the manifestation of Lorentz symmetry violation due the change in vacuum refraction index near massive objects – so it can be considered as a quantum gravity phenomena as well.

    By another words, the gravity can be considered as a dual effect of Universe expansion the dual nature of relativity and quantum mechanics is given by the fact, the relativity is describing the Universe from inside perspective, while the quantum mechanics is describing the it from the external one.
