Hey mate!

Here's your answer!!

➡ In astronomy dark matter is a type of matter which is believed to account for a major part of the total mass in the universe.

➡ It does not emit or absorb light or any other electromagnetic radiation.

➡ It cannot be seen with the help of a telescope.The existence of dark matter and its properties are inferred from its gravitational effects on visible matter, radiation, and the large-scale structure of the universe.

Answer 2

Dark matter is composed of particles that do not absorb, reflect, or emit light, so they cannot be detected by observing electromagnetic radiation. Dark matter is material that cannot be seen directly. We know that dark matter exists because of the effect it has on objects that we can observe directly.
