Einstein's Theory Of Special Relativity

The biggest equation to come out of Einstein's theory of special relativity is E = mc^2, which tells us how E, the energy, M, the mass, and C, the speed of light, are related to each other. This mass we are using is not the same as weight. An object's mass is how much stuff is inside of it, while its weight is how hard gravity is pulling on it. This is why when you measure your weight in outer space, it is close to zero.
Einstein's theory states that, the speed of light becomes a sort of ultimate speed limit. In fact, objects with mass, be they cars or neutrinos, can't reach the speed of light because they would need infinite energy to do so, according to the theory.
According to Einstein, when objects approach the speed of light, time for
