Dark matter is (in some cosmological theories) non-luminous material which is postulated to exist in space and which could take either of two forms:
1. Weakly interacting particles ( cold dark matter )
2. High-energy randomly moving particles created soon after the Big Bang ( hot dark matter ).
I hope this answer helped you.
