A Short History of Nearly Everything
Part of 15/36

f potential energy contained within all the atoms and molecules in your body. If you were to unleash all the energy in your body you’d generate an explosion equivalent to 30 hydrogen bombs. 
And this energy isn’t just found in our bodies. Everything with mass – every rock life-form and planet – has a huge amount of potential energy.
Albert Einstein described this connection between mass and energy in his most famous equation: E =m c2 or energy equals mass times the speed of light squared . 
Put very very simply E = mc2 explains how mass and energy are pretty much the same thing. Mass is simply potential energy ready to be unleashed. But this wasn’t Einstein’s final discovery.
The key message in this blink is: Einstein’s general theory of relativity totally changed how we look at gravity.
Published in 1917 Einstein’s general theory of relativity proposed the revolutionary concept of spacetime . As the name suggests spacetime combines the three dimensions of space with a fourth dime
