Faster-than-light

Faster-than-light (superluminal or supercausal) travel and communication are the hypothetical propagation of matter or information faster than the speed of light in vacuum (c). The special theory of relativity implies that only particles with zero rest mass (i.e., photons) may travel at the speed of light, and that nothing may travel faster.
