Why would it take an infinite amount of energy to propel an object at the speed of light? I'm a layman so, as per usual, please correct me if I'm hopelessly misguided... As one approaches the speed of light© the objects mass increases exponentially as it gets closer and closer to c. So the energy taken to move it faster than it is currently travelling increases exponentially as its speed increases(gets closer to c). Light has a finite speed. And numbers have no end (are infinite) and can describe any numerical value, no matter how hopelessly large --> Should the energy not then be finite but almost unimaginably emmence? Is the energy taken simply stated as "infinite" because there isn't so much energy in the observable universe?
