In a recent experiment a laser pulse was measured to be traveling at 300 times c. What justice does the gamma factor or special relativity as whole do to this scenario?

Thanks for your reply. By question 2, I meant if we were solve the gamma factor equation for a photon we have a denominator of zero given by the square-root of (1 - v^2/c^2) where v will be c since we are dealing with a photon. So what does that mean? And sorry for my silly argument, I am...

Hi I would just like to ask a few questions bugging me. 1. Why do we regard a photon as having no-rest mass. Is the fact that a photon is 'never' at rest enough of a reason. 2. Why don't we take the photon into consideration when dealing with the gamma factor. 3. Our most sensitive...
