At extremely large scales, galaxies are not distributed randomly, but in structures that have been described as bubbles, void in the center, with the galaxies existing on the skin of the bubble. All bubbles have a compression component, ie. air pressure, and a tension component, ie. surface tension. In these bubbles of galaxies, gravity would provide the tension, while dark energy in the center of the bubble would then provide the compression component. Since we don't know exactly what dark energy is, I think we should consider this explaination as an alternative to the view that it is something homogenously distributed, or built into the fabric of space-time.
Re: Is dark energy responsible for the distribution of galaxies?
