Time Dilation - Einstein's Theory Of Relativity Explained!

There is absolutely no doubt that after Newton, Einstein is the most popular physicist in the history of science. Between the March and June of 1905, Einstein, then a mere patent clerk, published four papers that revolutionised modern physics forever. Although he became a household name for discovering the ever-famous E=mc2, it was time dilation that completely changed our understanding of space and time. What's more, the principle occurred to him in a daydream. Watch our new video to understand what is time dilation and find out why your head is older than your feet!
