There's a very odd experiment that seems to suggest that it is possible to send information faster than light.
Two devices sending individual photons (I think) one through the air and the other through a solid block of something (I forget what). The ones going through the solid object arrive at the destination quicker than the ones going through nothing, meaning that they are travelling faster than light.
The explanation for this is quantum tunneling, which is based around the uncertanty principle - i.e. you never know where something is, and there's a slim chance it could be in two places at once. This experiment appears to confirm the theory.
