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.
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)
Exotic particles are frequently featured in science fiction, either those with real-world academic backing, or entirely fictional.
Famous quotes containing the words exotic and/or particle:
“I did not know the woman I would be
nor that blood would bloom in me
each month like an exotic flower,
nor that children,
two monuments,
would break from between my legs....”
—Anne Sexton (19281974)
“Love is life. All, everything that I understand, I understand only because I love. Everything is, everything exists, only because I love. Everything is united by it alone. Love is God, and to die means that I, a particle of love, shall return to the general and eternal source.”
—Leo Tolstoy (18281910)
