The common assumption is that if one considers only sufficiently large scales, the universe appears homogeneous. This ignores the two largest substructures of the universe: filament regions and voids. In these regions, the effects of gravity are extremely different. In the massive filaments, time passes more slowly; in the massless voids, more quickly. As space tend to expand* in general, it expands faster in voids than elsewhere. | |||
: *Quantum fluctuations show that the vacuum is not a dead space, but an active one. Virtual, ultra-short-lived, particles exert pressure on their surroundings. The more empty space is the more this effect contributes to the drift due to time dilatation. | |||
As consequence almost all galaxies seem to drift apart, then even seem to "accelerate" and create the illusion of an unknown "dark" energy being involved. In the less heavier outer arms of galaxies, it can be observed that, according to the conventional standard model, they move too quickly. Here too, [[wp:Time_dilation|time dilation]] based of different mass distribution causes a distorted perception of reality. | |||
