FactoidFaster-than-light (FTL) travel refers to the propagation of matter faster than the speed of light. Under the special theory of relativity, a particle with subliminal velocity needs infinite energy to accelerate to the speed of light. A hypothesis titled ‘Alcubierre drive’ is a speculative idea proposing that a spacecraft could achieve FTL if negative mass existed.
