We can design a photon accelerator that accelerates the photons even though the photons have no rest mass in order to do mechanical work on them, they have no electric charge to interact with the electric or magnetic field, they move at the maximum speed in a vacuum, which is the speed of light, i.e. No more speed, but through a new hypothesis called the dimensional rest mass hypothesis, we can find solutions to the three reasons that prevent us from accelerating photons and design an accelerator of photons called the dimensional photon accelerator works with a new principle that is not used in particle physics, which is the acceleration between the dimensions of spatial space, The work of the accelerator is a test of the dimensional rest mass hypothesis, Therefore, it is also a test of the inverse relativity theory, which relied mainly on that hypothesis, This is the main purpose of designing this accelerator.
