Dark matter is an invisible form of matter that makes up approximately 85% of the matter in the universe. Dark matter does not emit or absorb light, and it is not made up of atoms.
1. Dark matter does not emit or absorb light, and it does not interact with the regular matter that makes up stars and planets.
2. Dark matter does not emit or interact with light, making it extremely difficult to detect.
3. The first evidence for dark matter came from the observation of anomalous motions of stars in the Milky Way.
4. In the 1970s, Vera Rubin and Kent Ford discovered that the rotation curves of spiral galaxies did not obey Newton's laws of motion, which provided strong evidence for the existence of dark matter.
5. Dark matter is thought to be composed of weakly interacting massive particles (WIMPs).
6. The leading candidate for the identity of dark matter is the neutralino, a hypothetical particle that is a supersymmetric partner of the Standard Model Higgs boson.
7. The search for dark matter is one of the major goals of particle physics and astrophysics.
8. The nature of dark matter is one of the biggest mysteries in astrophysics, and scientists are still working to understand what it is and how it behaves.
9.Dark matter is also thought to play a role in the formation of large-scale structure in the Universe.
10. The nature of dark matter is one of the great mysteries of modern science.
