It is the title of the Nature article

(Arxiv:0908.1832

) from the Fermi Gamma-ray Space Telescope

collaboration about the reconstruction of the gamma-ray burst GRB090510, observed on May 10, 2009. Their results disfavour quantum-gravity theories, in which the quantum nature of space–time on a very small scale linearly alters the speed of light.

A detailed discussion of the results can be found in this entry
