Promponents of some quantum theories for gravity believed that there would be very slight variations in speed related to frequency -- these observations show that if there is a variation it must be very slight.
Looks like Einstein's general relativity is still keeping the quantum physicists at bay ...

Quoting Francoflier (Reply 1): That must be a huge slap in the face to many Quantum physicist and many of their theories.
...Back to the blackboard.
The struggle continues -- quantum physics still works quite well until things get down to the Planck scale (where the effects of gravity might begin to affect quantum physics) -- but once at that point, attempts to unify gravity with the other forces start to break down.
Unifying gravity with the "rest of physcis" has perplexed scientists ever since Einstein published his work in 1915.

Quoting Burkhard (Reply 3): And even if the Higgs Boson can be pinned down, we are at the beginning, not the end of understanding...
To me, that seems very likely.
One of my favorite authors of physics/math books aimed at the layman is Roger Penrose -- he certainly isn't afraid to take controversial positions -- he feels that there needs to be at least one more major revolution (as were quantum mechanics and general relativity) before we get to the bottom of things ... if ever ...
