From Newton’s second Law we know that when a force F acts on a mass m, the acceleration (rate of change of speed) a, produced is given by a = F/m. However, experiments conducted on electrically accelerated particles showed, quite conclusively, that at very high speeds this is not the case. The magnitude of the acceleration produced by the same force gradually tapers off in a manner that it tends toward zero as the particle speed approaches the speed of light. So much so, Einstein had shown that no material particle could ever be accelerated to this limiting speed. Since then it has become an accepted dogma in all the physical fields. Even in situations where the empirical evidence clearly indicated existence of faster than light speeds—like in some quasar redshifts—the scientists simply denied the facts, because of their unquestioned servitude to Einstein’s ideas. This, of course, has had the disastrous result of stumping the development of physical theory.
