i thought it was 70%.
it does not release or absorb light so we can't see it or find informaton about it.
it is so heavy so it has a strong gravitational force and does not let the universe eexpand so fast.
but no one exactly knows its property and its existance is not 100%

The most important quality of the black matter is that the force of attraction is so big that it doesn't allow light to be reflected.

best eg. is a black hole. the phenomenon is matter is squashed soo tightly together( for eg. say the entire matter of the sun squashed to the size of a grain of sand and this at the size of the sun ). it is alb to absorb even the light through sheer gravity.
