The expansion of the universe should slow as time marches on, some even conjectured it would slow and then collapse again - that's what all that mass and its gravity in the universe should do.But Hubble showed us distant supernovae in the 1990s and researchers realized the universe had actually been expanding slower in the past, not faster - and that was a pickle for current theory. So researchers hypothesized Einstein's theory of gravity and a cosmological constant might account for it, or some strange kind of energy-fluid filled space or Einstein's theory of gravity was wrong and a new one including some kind of field creates cosmic acceleration. No one knew what it was, but they called this mystery Dark Energy.read more
