Time goes by so slowly . . . well, only if you happen to be travelling at the speed of light! In this BrainPOP UK movie, Tim and Moby introduce you to relativity – the theory that explains how motion, time, space and gravity work. In this educational, animated movie you’ll find out the difference between special relativity and general relativity, and where E=mc² fits into the puzzle. You’ll also learn the contributions of Sir Isaac Newton and Albert Einstein, find out what spacetime is, and try a fun experiment that lets you feel the force of gravity on your body! Everything is relative!
