I don't think there is anything in the universe that can travel faster than the speed of light in a vacuum, but there are some nice effects of things travelling faster than light, such as Cerenkov radiation.  This happens when a charged particle travels faster than light in a specific medium, and the effect is kind of like a sonic boom, with photon emission.

Another extreme of physics is that the periodic table is expected to end at a certain atomic number (postulated by Bohr to be 137), because the magnitude of the nucleus would require the electrons in orbit to travel faster than light.

Sorry I can't answer if anything travels faster than 299792458metres per second, I hope this is at least of interest :-)

I should have mentioned that Hawking radiation can travel faster than the speed of light being absorbed, in some sense.  NS reported an experiment where LASER light was fired at a glass block, at such high intensity that the speed of transmission in the block itself essentially became infinite (induced negative refractivity maybe?).  Anyway, the photons were of such intensity that they slowed down and eventually stopped inside the material, resulting in bursts of radiation at right angles to the beam.  The group said it was proof of Hawking radiation.

the way i understand it light is massless energy anything with mass takes energy to move therfore nothing with a mass can travel as fast as light because energy-mass=velocity

The laws of physics seem to say that no massive object can appear to travel at the speed of light (in a vacuum) relative to an observer in the same region of spacetime. This is what we commonly mean by “travelling at the speed of light”.  However, because the fabric of space itself ("spacetime") itself is expanding, it is certainly possible that objects which are separated by large distances (tens of billions of light years) can appear to travel away from each other at faster than the speed of light.  In such case they will appear to be further and further redshifted as they "expand" away from each other closer and closer to the speed of light, until finally they disappear from view altogether as they "pass the speed of light".  This is likely to happen if the current accelerating expansion of the universe continues.

But things change if the observer and object are separated by large distances (billions of light years). This is because the fabric of space itself (“spacetime”) itself is expanding, and this expansion can carry two massive objects away from each other at faster than the speed of light.  In practise they will appear further and further redshifted as they accelerate away from each other closer and closer to the speed of light, until they disappear from view altogether as they “pass the speed of light”. This is likely to happen if the current accelerating expansion of the universe continues.
