The Special Theory of Relativity assumes Lorentz Invariance....the laws of physics must look the same in all refrence frames. Some speculated that gamma ray bursts showed the separation of photons of different energies implying that they therefore traveled at different speeds, and hence were Lorentz Invariant. Not so....(results strongly disfavor this view). SEE:http://arxiv.org/PS_cache/arxiv/pdf/1008/1008.2913v1.pdf

You mean, and hence violated Lorentz invariance?

BTW, don't C, P, T, CP, and CPT symmetries (http://en.wikipedia.org/wiki/CPT_symmetry) all show slight violations of Lorentz invariance?

No. That's not what Special Relativity says. Special Relativity says the laws of physics must look the same in all INERTIAL reference frames. Add acceleration and some serious mathematical bonage begins. That's what General Relativity is for.
