Web2 Answers. 1) It is impossible for matter to go at the speed of light, as it takes an amount of energy equal to m c 2 ( 1 1 − ( v c) 2 − 1) to accelerate it to a speed v, and this energy becomes infinite as v → c. In another sense, reference frames moving at the speed of light (or faster) are excluded from Einstein's principle of equivalence. Web40 minuten geleden · NASHVILLE, Tenn.
