Which statement accurately describes dark matter? It is the same as dark energy. It is well understood by scientists. It does no
kow [346]

Answer:

Dark matter does not emit electromagnetic radiation.

Explanation:

Dark matter comparative to dark energy, has various differences. You could say that dark energy is put into action on a larger scale than dark matter, which is also why dark energy makes up 74 percent of the universe. Thus, dark matter ≠ dark energy.

Scientists have a lot to learn about dark matter, so we can't claim that this subject has been well understood about scientists. In fact, it is one of the least understood parts of the universe!

_______________________________________________________

Now dark matter can be defined as particles that do not absorb, reflect, or emit light. Thus, it can't be observed by electromagnetic radiation - nor shifts in red and blue light. At the same time it does not emit electromagnetic radiation.
