The majority of dark matter is probably not protons and neutrons.

Question

Quizplus · Accepted Answer

Protons and neutrons are made up of quarks and therefore interact through the strong nuclear force, while dark matter does not interact through any of the fundamental forces except for gravity. Therefore, the majority of dark matter is not made up of protons and neutrons. Protons and neutrons make up normal matter, but dark matter is believed to be made up of particles that interact weakly with normal matter, such as WIMPs (weakly interacting massive particles).
