# It is impossible ever to transmit information faster than the speed of light.<ref>This assumption is commonly restated in this manner.  For example, an discussion of hypothetical [[tachyons]] says, "about using tachyons to transmit information faster than the speed of light, '''in violation of Special Relativity'''?[http://www.math.ucr.edu/home/baez/physics/ParticleAndNuclear/tachyons.html]  However, some question whether the Theory of Special Relativity really restricts faster-than-light communication of information.</ref>
