Brylee Tyler · Answer 1

The dark matter is referred to a hypothetical form of matter, which account for almost 85% of the matter present in the universe. The dark matters are invisible and are known to be invisible. Due to invisible nature, the dark matter is still not well understood by scientist.

The invisible nature of the dark matter is because, they do not emit any electromagnetic radiation, hence, they do not produce or emit any light shifts. They produce gravity, an attractive force, hence, they are different from dark energy, which produces antigravity or repulsive force.

So, the correct statements about dark matter are:

It is invisible.

It can be observed by shifts in red and blue light.
