In this illustration, one photon (purple) carries a million times the energy of another (yellow). Some theorists predict travel delays for higher-energy photons, which interact more strongly with the proposed frothy nature of space-time. Yet Fermi data on two photons from a gamma-ray burst fail to show this effect, eliminating some approaches to a new theory of gravity.

Here’s the Ars Technica I couldn’t use because of copyright restrictions through the failing Conde’ Nast:

Some models suggest that the time difference might be
proportional to the square of the energy difference
scaled by the quantum gravity mass

Anyone with even half a brain knows that....

Makes sense to me.

Sounds a lot like this thread I posted back in June:

>>>the mass scale must be at least 1.2 times the Planck mass, and by using reasonable but less conservative assumptions, they derived lower limits on the mass scale of up to 100 times the Planck mass.

I was thinking that just the other day. Darn I knew I should have written it down.
