Reply to comment by scaradin in The Nancy Grace Roman Space Telescope - the next major step in astronomy that will help unlock the secrets of the universe's expansion and dark energy. by upyoars

I hate to be 'that guy', but:

Dark matter and dark energy are completely different, and from my layman's understanding - having opposite effects.

Dark matter (DM) is used to explain excess gravity observed in the universe - an attractive force.

Dark Energy is used to explain the observed accelerating expansion of the universe - a 'repulsive' force (not technically true, but observationally convenient phrasing).

Black holes are postulated to be possibly connected to the dark energy thing.

Upvoted for Ace Ventura reference.
