Answer 1

Dark matter is the invisible, hypothetical matter that makes up most of the universe. It cannot be directly observed but can be inferred through the motion of stars and galaxies. It has significant implications for particle physics and cosmology.

Step-by-step explanation:

The invisible, hypothetical matter that makes up most of the universe is known as dark matter. Dark matter is non-luminous matter that cannot be directly observed but can be inferred through the motion of stars and galaxies. It is estimated to make up about 90% of all matter in the universe and has implications for particle physics and cosmology.
