Can there be something faster than speed of light? This is the question that occasionally come into mind of physics students. The speed of light is 3 x 100000000(meter/sec. Basically the answer of this question lies in the Einstein postulates of theory of relativity.

Mr. Einstein gave his theory of relativity. According to one of his postulates that nothing can travel faster than the speed of light and speed of light is constant for free space or vacuum.

This was his theoretical assumption and the he was so great and of course he is still great that no one till date can prove him wrong. Scientists tried so many times to disapprove this concept but always failed. Recent example is some scientists proved through their research that neutrinos can travel faster than the speed of light. But at the end they also failed to prove this to the world. I will discuss about neutrinos later on. For today, I can just tell that neutrinos are elementary subatomic particles and they are everywhere and travel near to the speed of light.

But no one was able to prove Einstein wrong means till that no one can travel faster than the speed of light.
