How do light years work
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. WebWhile the Big Bang happened around 14B years ago, that does not mean that 13B years ago, the Universe is 1/14th of its present size. Current theory suggests that a large portion of the cosmological inflation (where the Universe increased by 26 or more orders of magnitude in linear dimensions) happened within much, much less than a second after ...
