When we were kids, We were amazed that Superman can travel faster than the speeding bullet or a jet. We often think what if we travel at the speed of light? Here's the answer! Einstein's equation E = mc², where E is the energy, m is the mass and c is the speed of light. According to it mass and energy can be changed into each other. Due to this equivalence, the energy object has due to its motion will increase its mass. In other words, the faster object moves , the greater its mass. If an object moves at 10 percent speed of light, its mass will only be 0.5 percent more than the normal. But if it moves 90 percent the speed of light, its mass will become double. According to the special theory of relativity, time in a moving reference frame( say your spaceship) goes slower as compared to stationary frame (say Earth) the faster you go.
