Re: FTLparticles

I thought the whole point was that a tachyon is the name for a particle that travels faster than light. But none actually exist.

Cherenkov radiation is shed by when a particle that would have been travelling faster than light in the medium it finds itself in suddenly hits reality face first. Energy is shed, lovely blue glow, particle travelling at a valid speed, causality is preserved.
