Exotic particle

From Wikipedia, the free encyclopedia

An exotic particle is a kind of theoretical particle said to exist by some areas of modern physics, and whose alleged properties are extremely unusual.

The best-known example is probably the tachyon, a hypothetical particle that always travels faster than light.[1][2]

Another example of this is supersymmetry, a theoretical set of significantly heavier versions of known particles (this is also one of the proposed candidates for dark matter). [3]

Exotic particles are frequently featured in science fiction, either those with real-world academic backing, or entirely fictional.
