Several leading quantum gravity theories predict that there is a dependence of the speed of light on photon energy, which would bridge ...

Several leading quantum gravity theories predict that there is a dependence of the speed of light on photon energy, which would bridge incompatibilities between general relativity and quantum physics.

The speed of light has been one of science’s most trusted markers of stability. For more than a century, the idea that light ...
