The LHC website states that LHC can accelerate protons to 0.999999991 c.
Let's say that this acceleration costs the energy of one power plant for 1 hour (it's an hypothesis, i don't know the real energy cost).
Before acceleration, the proton was in the same inertial reference frame that the rest of the univers (if we consider univers to be static); but after the acceleration the univers and the proton are in two distincts inertials references frames with relative speed of 0.999999991 c. As in SR there is no prefered referential frame, can we conclude that, from the point of view of the proton, that accelerating the universe to 0.999999991 c costed the energy of one power plant ?
