yeah, I heard about that - I think they sent a laser beam through some sort of crystal and supposedly the light reached its destination before it left its source. Seems pretty strange to me, but it wouldn't suprise me if it was possible. The special and general theories of relativity states that light is the universal speed limit, but this isn't proven beyond a doubt (although it is an integral part of Einsteins theories). However, quantum mechanics opens the door for faster than light travel with its theory on 'quantum entanglement' in which two molecules derived from the same source can transmit information between each other instantaneously (regardless of the distance apart). This doesn't seem to bother physicists though, because they are only interested in whether we can send information faster than the speed of light, but I don't see why changing the properties of a particle, such as spin, velocity or position (and hence changing the properties of the other particle) can't transmit some form of information.
Although physics is strongly opposed to anything moving faster than the speed of light (and thus time travel), our current theories are far from the end of the story. Everyone thought Newtons laws of motion were absolute and no-one ever doubted them. Einstein changed all that, causing a huge paradigm shift in physics thought. I don't see why that won't happen again (infact, it's highly probable).
