Question

If it is possible to travel at the speed of light. The why have'nt any traveled at the speed of light?

Answer 1

$\large\bf\red{here\:is\:ans}$

Einstein's Special Theory of Relativity permanently tied mass and energy together in the simple yet fundamental equation E=mc2. This little equation predicts that nothing with mass can move as fast as light, or faster. ... (The reason particles of light, called photons, travel at light speeds is because they have no mass.)..
