Lemins

Lemins are a hypothetical class of subatomic particles that have been proposed as a potential candidate for dark matter. The concept of lemins was introduced by physicist Adam Falk in 2018. According to the theory, lemins would be very light, weakly interacting particles, similar in some ways to neutrinos. However, unlike neutrinos, lemins would possess a small but non-zero mass, and they would interact via a new fundamental force, which Falk termed the "lemin force."

The proposed lemin force would be much weaker than the electromagnetic or nuclear forces, and it would only operate over very short distances. This weak interaction would explain why lemins have not been directly detected in experiments so far. The idea is that lemins would form diffuse "clouds" around galaxies, and their collective gravitational influence would account for the observed dark matter effects.

If lemins exist, they could also play a role in the early universe, potentially influencing the formation of cosmic structures. Current research on lemins is theoretical, and experimental efforts are underway to search for indirect evidence of their existence. These searches often involve looking for specific decay products or subtle gravitational effects that could be attributed to lemins. The existence and properties of lemins remain speculative, and further theoretical and experimental work is needed to confirm or refute their presence in the universe.
