Bien évidemment, on prend ceci avec des pincettes puisque à de nombreuses reprises la vitesse de la lumière a été contesté et pourtant, elle en sort toujours gagnante.A much more controversial observation is an energy dependence in the speed of light of cosmic rays coming from a short burst of the blazar Markarian 501 on July 9, 2005. Photons with energies between 1.2 and 10 TeV arrived 4 minutes after those in a band between .25 and .6 TeV. The average delay was .030±.012 seconds per GeV of energy of the photon. If the relation between the space velocity of a photon and its energy is linear, then this translates into the fractional difference in the speed of light being equal to minus the photon's energy divided by 2×1017 GeV.
Quelqun s'y connais un peu sur le sujet? Aurait un article avec plus de détails à fournir?
