Is there any evidence for dark matter?

Question

I have always heard about dark matter, but I do not know what it means, what its uses are, and does it really exist?

In: Chemistry

Answer 1

Dark matter is invisible and doesn’t interact with light or radiation, but scientists believe it exists because of its gravitational effects on galaxies and the universe. For example, stars on the edges of galaxies rotate faster than they should, indicating unseen mass. Phenomena like gravitational lensing and cosmic background radiation also support the idea of dark matter. While it hasn’t been directly observed, strong evidence of its existence comes from its gravitational effects.
