What’s the Difference Between Dark Matter and Dark Energy

Dark matter and dark energy are the yin and yang of the cosmos. Dark matter produces an attractive force (gravity), while dark energy produces a repulsive force (antigravity). Together, they make up 96 percent of the universe and we can’t see either. Astronomers know dark matter exists because visible matter doesn’t have enough gravitational muster to hold galaxies together.

Hey it is dark not black matter

Answer 2

Dark matter slows down the expansion of the universe, while dark energy speeds it up. This is because dark matter does interact with gravity, but it doesn't reflect, absorb, or emit light.
