Badly off topic for newsgroup so I will make it brief: the answer below supposes you are not quite travelling at the speed of light. If you actually were (could) travel at the speed of light there would be no distance between any two locations (all spatial distances contracted to zero length) so there would be nothing to illuminate. In part, this is the reason that although photons are particles the concept of size (dimensions) of a photon is meaningless. "Douglas C.
