Cosmology: quantum space time not Einsteinian (Introduction)

Gamma ray burst split into two waves four minutes apart, lower energy first, then higher energy. Doesn't fit Einstein's space-time general relativity theory. Difference explained here:-"And detailed analysis revealed something decidedly unusual about the burst: the lower energy radiation seemed to have arrived up to 4 minutes before the higher energy radiation Movie Camera. This is a big no-no if space-time behaves according to Einstein's relativity. In relativity's smooth space-time, all light travels at the same speed regardless of its energy. But the effect was entirely compatible with other, rival theories that attempt to characterise space-time in terms of quantum mechanics - the theory entirely separate to, and incompatible with, general relativity that explains how everything besides gravity works.-"In quantum theory, nothing is static or certain. Particles and energy can fluctuate and pop in and out of existence on the briefest of time scales. Many theories of quantum gravity - the yearned-for "theories of everything" that will unify our descriptions of space-time and gravity with quantum mechanics - suggest something similar is true of space-time: instead of a smooth continuum, it is a turbulent quantum foam with no clearly defined surface. Einstein's undulating landscape becomes more like a choppy seascape through which particles and radiation must fight their way. Lower-energy light with its longer wavelengths would be akin to an ocean liner, gliding through the foamy quantum sea largely undisturbed. Light of higher energy and shorter wavelengths, on the other hand, would be more like a small dinghy battling through the waves."-http://www.newscientist.com/article/mg22129500.700-breaking-relativity-celestial-signals-defy-einstein.html?page=1#.VRhpv2BFC1s-The New Scientist is an excellent source, and if you sign up you can see many great articles. There is no catch and no harm to do this. I've followed it for years.
