Is lightspeed really a limit? • The Register: "We don’t (yet) have any way to test this, but University of Adelaide applied mathematicians are suggesting that an extended version of Einstein’s Theory of Special Relativity also holds true for velocities beyond lightspeed.
One of the main predictions of Special Relativity is that the speed of light is treated as an absolute cosmic speed limit, the line which can never be crossed; and even the notorious ‘faster-than-light neutrino’ incident in 2011 has left the theory intact as one of the most robust in physics.
However, during the speculation that surrounded the neutrino discussion last year1, the University of Adelaide’s Professor Jim Hill and Dr Barry Cox considered the question of how the mathematical contradictions posed by a faster-than-light particle could be aligned with Special Relativity.
Their solution, which Professor Hill discussed with The Register,2 rested on ignoring the speed of light’s status as an absolute limit, and instead, using the information where the relative velocity of two observers is infinite."
