Light speed variation from gamma ray burst GRB 160509A

Light speed variation from gamma ray burst GRB 160509A

It is postulated in Einstein's relativity that the speed of light in vacuum is a constant for all observers. However, the effect of quantum gravity could bring an energy dependence of light speed. Even a tiny speed variation, when amplified by the cosmological distance, may be revealed by the o...
