I'm confused. Why is the cosmological constant then also called dark energy if it's not equivalent to there being some energy in empty space?
- fnordpiglet 3y agoDark energy isn’t energy in a conventional sense (hence its disclaimer). In fact it isn’t known to actually exist and is more a placeholder explanation of the apparent expansion effects and ascribing some universal energy that can account for the expansion and the resistance to expansion gravity seems to exert. No energy is expended or moved to cause expansion as dark energy is constant and universal.
