Did Dark Energy Just Disappear?

Season 2 Episode 25 | 12m 14s | Video has closed captioning.

Why are we talking about dark energy again? Because another team has just announced a new analysis of updated supernova data. They claim that the data are consistent with there being NO dark energy – no accelerating expansion. They suggest that the universe may just be expanding at a constant rate – never speeding up, but also not slowing down.
