Except for an obvious inconsistency. In the first exoeriment the claim is that the speed of light exceeds the default speed by a factor of 300.

But they go on to say that the main spike of the beam leaves the cesium chamber before it enters it. That of course is a logical impossibility proving that either science or nature is irrational. I happen to think that nature is irrational as I've stated many times in this forum.

But the data presented is insufficient for any evaluation of the validity of the experiments. We just have to wait until the magazine NATURE publishes the results.

In the second experiment, the light detector must be at the focus of the light rays. However, we are not told if the incident beam of light illuminates the entire mirror at once or is it a thin beam that scans the mirror. If full, the detector is in a diffractive region where phase information is lost. So I am not surprised to find 5% deviations from the norm. Nature is still rational in this experiment
