Warp one, Engage!Light slows down when it's not in a vacuum, and you can sometimes gets particles passing through a material that are going faster than the speed of light in that material. They cause a cool shockwave burst of light called Cerenkov Radiation which is like the light version of a 'sonic boom'.
One wierd thing scientists have spotted is that light can seem to tunnel or jump from one side of a material to the other faster than the speed of light in a vacuum, which is supposed to be impossible.
Thats why they're trying to revise the rules to mean that information cannot be transmitted faster than light, cos thats when you start getting all sorts of fun causality loops and the like.

.When you say "they're" , you actually mean "you're" don't you? Go on, admit it!
