Question

Why is dark matter interesting and important?

Answer 1

Dark matter:

1. Dark matter was crucial in the formation of galaxies.
2. Astronomical surveys are used by researchers to create maps of the location of dark matter in the universe based on how light from distant galaxies bends as it travels to us.
3. Despite its invisibility, dark matter has played an important role in the evolution of our universe, as well as the formation of stars, planets, and even life.
4. This is because dark matter has five times the mass of ordinary matter and does not interact with light directly.
