Question

What do you mean by DARK MATTER in chemistry ( class 10 )

Answer 1

Dark matter can refer to any substance which interacts predominantly via gravity with visible matter (e.g., stars and planets). Hence in principle it need not be composed of a new type of fundamental particle but could, at least in part, be made up of standard baryonic matter, such as protons or neutrons.

Answer 2

Answer:

non-luminous material that is postulated to exist in space and that could take any of several forms including weakly interacting particles ( cold dark matter ) or high-energy randomly moving particles created soon after the Big Bang.
