Tachyon—Even Faster Than Light[edit]

Tachyons are particles that can travel faster than light. The idea of Tachyons was first floated by Arnold Sommerfeld, a physicist, and later named by Gerald Feinberg. The name Tachyon was coined from the Greek name tachus, whose literal translation is “speedy”. The basic principle behind Tachyons is that they gain speed when they lose energy and lose speed when they gain energy. The slowest speed of Tachyon is the speed of light.
