prove it.

the best you can say for sure is that distant massive bodies are accelerating away from each other. there are a few flimsy theories as to why it is happening, one of which is that there is some kind of dark matter between normal matter which is pushing normal matter around. even if that were the case, the motivation of normal matter would never exceed the speed of light.

Hi, most accepted Dark Energy theory is not based on material/dark particles pushing objects away from each other, you may mix it with Dark Matter theory (explaining "missing" mass of galaxies etc). However, I see that this thread was to explain the issue that universe is larger than light speed would allow, and for this purpose explaining the topic on the currently accepted hypothesis/theories is logical to keep the answers simple. Discussing proving of the dark energy theory and especially doscussiong alternative theories for sure deserve their own thread.
