In short, dark matter slows down the expansion of the universe, while dark energy speeds it up. Dark matter works like an attractive force — a kind of cosmic cement that holds our universe together. This is because dark matter does interact with gravity, but it doesn’t reflect, absorb or emit light.
Does dark matter cause expansion?
Astronomers theorize that the faster expansion rate is due to a mysterious, dark force that is pulling galaxies apart. One explanation for dark energy is that it is a property of space. … As a result, this form of energy would cause the universe to expand faster and faster.
What would happen if dark matter decreased?
If all dark matter disappeared, stars on the edge of galaxies would begin to drift out of the galaxies over time. Once the gravitational effect of dark matter had fully disappeared (it takes time because gravitons move at the speed of light), stars at the edge would start leaving their host galaxies.
