Nothing

I have no Idea what possesed you to ask such an esoteric question in this place, which basically is a graveyard for insults. I mean look at the answers above. Anyhow .... the short answer is nothing that we know of yet. What we do know is certain charachterstics said "thing" would have. Its effects on mass,dimension and time. Look into Lorentz's principles and the theory of relativity and assume velocity to be c - speed of light. Look into any decent book on modern physics .As for the black hole argument, innwards from the event horizon the black hole is due to the gravitational singularity at its core. Photons just doesn't have the energy to escape the gravity. So its more to do with the energy as opposed to the velocity.
