More parodox on the motion of light in free space

New Scientist: Just that phenomenon has already been seen, starting with some unusual observations made by a telescope in the Canary Islands in 2005 (New Scientist, 15 August 2009, p 29). The effect has since been confirmed by NASA's Fermi gamma-ray space telescope, which has been collecting light from cosmic explosions since it launched in 2008. "The Fermi data show that it is an undeniable experimental fact that there is a correlation between arrival time and energy - high-energy photons arrive later than low-energy photons," says Amelino-Camelia.

And this:

"It has been obvious for a long time that the separation between space-time and energy-momentum is misleading when dealing with quantum gravity," says physicist João Magueijo of Imperial College London. In ordinary physics, it is easy enough to treat space-time and momentum space as separate things, he explains, "but quantum gravity may require their complete entanglement". Once we figure out how the puzzle pieces of space-time and momentum space fit together, Born's dream will finally be realised and the true scaffolding of reality will be revealed.

Why would they differ, high energy gamma rays and ordinary light? For one thing, their quantization ratios are different, so their impedance in free space is different. What do we know about impedance and curvature?  If there is no phase alignment in free space, then they do not matter. If there is some phase alignment then it matters a whole lot.  It is whatever phase alignment there is, and it might not just be gravity.

Scientist make the mistake of assuming space impedance is a function of space, when it is a function of the relative quantization ratios of the two phase modes doing the swirl.  The second mistake scientist make is assuming that only gravity causes phase alignment.  Galaxies cause phase alignment on top of gravity, they are semi-independent of gravity.

The relative quantization ratio within the atom are from the positive phase boundary caused by the electron in motion, and the positive phase boundary caused just by the electron charge, which is negative, and the negative phase quantization of gluons which is massive.

So space impedance, the difference in quantization, is huge for gamma wave compared to EM wave, likely a 50 times difference.  Any mild phase alignment causes the high impedance to curve more, it will  loop a bit along is minimum path path.
