Dark energy is not needed as '''[[wp:Inhomogeneous_cosmology#Timescape_cosmology|timescape cosmology]]''' can explain its effects. | Dark energy is not needed as '''[[wp:Inhomogeneous_cosmology#Timescape_cosmology|timescape cosmology]]''' can explain its effects. | ||
* 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 [https://www.youtube.com/watch?v=yDAAlojz8NU 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. | * The common assumption is that if one considers only sufficiently large scales, the universe appears homogeneous.

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. As consequence almost all galaxies seem to drift apart and create the illusion of an unknown "dark" energy being involved. | ||
* Also, 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. | * Also, in the less heavier outer arms of galaxies, it can be observed that, according to the conventional standard model, they move too quickly.
