    Special relativity in theory allows for particles to go faster than light, although they could never slow down to light speed. These have been given the name tachyons. However there is no evidence they exist.

    Before String theory incorperated Super Symmetery to become Super String Theory tachyons were required for the theories to work out to fix infitinties

    Of course tachyons exist. Don't you remember when data discovered the cloaked romulan vesels???

    Of course then there's this amusing limerick i've heard.

    edit: found the author :D

    I have presented this argument in other threads, but tachyons do not exist or, at the very least, will never be discovered. See, if we were evr going to discover a partical to which the laws of causality apply in reverse, we would have found it sometime before we started looking.
