Exotic particle
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 theoretical particle that always travels faster than light.[1][2]
All particles have an intrinsic spin associated with the angular momentum of the particle. Whereas more common particles have spins of value 1/2, 1 and 0, some exotic particles (such as the Omega negative) has spin = 3/2.[3]
Another example of this would be supersymmetry. A theoretical set of super heavy versions of known particles (this is also one of the proposed candidates for dark matter) [4]
Exotic particles are frequently featured in science fiction, either those with real-world academic backing, or entirely fictional.
