GENERAL KNOWLEDGE

Detailed explanation-1: -Unlike normal matter, dark matter does not interact with the electromagnetic force. This means it does not absorb, reflect or emit light, making it extremely hard to spot. In fact, researchers have been able to infer the existence of dark matter only from the gravitational effect it seems to have on visible matter.

Detailed explanation-2: -Not only does dark matter not emit light or electromagnetic radiation, it doesn’t even interact with them. In fact, the only means by which scientists are confident dark matter interacts with ordinary matter is through gravity.

Detailed explanation-3: -A number of physicists have suggested that dark matter is made from Majorana particles, but Scherrer and Ho have performed detailed calculations that demonstrate that these particles are uniquely suited to possess a rare, donut-shaped type of electromagnetic field called an anapole.

Detailed explanation-4: -Dark matter is composed of particles that do not absorb, reflect, or emit light, so they cannot be detected by observing electromagnetic radiation. Dark matter is material that cannot be seen directly. We know that dark matter exists because of the effect it has on objects that we can observe directly.
