A) both controlled by large differences in the cosmic microwave background radiation

Question

Quizplus · Accepted Answer

Dark matter does not interact with electromagnetic forces, which means it doesn't emit, absorb, or reflect light, making it invisible and detectable only through its gravitational effects. This fundamental difference in interaction leads to different evolutionary paths for the distribution of dark and normal (baryonic) matter in the universe.
