Explanation:

Dark matter is a hypothetical form of matter that does not interact with electromagnetic radiation, meaning it cannot be seen directly through light - based observations. It is distinct from dark energy. Scientists do not fully understand it. Shifts in red and blue light (red - shift and blue - shift) are related to the motion of objects that emit electromagnetic radiation, which dark matter does not do.

It does not emit electromagnetic radiation.
