Yeah, the idea that Dark energy is something we know today, more than 17 years ago, doesn't seem accurate. We have has several astronomical surveys that indicate a range of things, and nothing for certain. One survey has indicated that because the universe is now guesstimated to have 10-20 times more galaxies, then estimated 25 years ago, this would wipe out dark matter as a source of mass.
?? Dark matter is the hypothetical gravitating stuff responsible for the rotation curves of galaxies. Discovering more galaxies has no relevance to it. The Bullet Cluster provides strong evidence that it doesn't interact with ordinary matter or with itself other than gravitationally.
