This equation brought revolution in science  as it has help us to understand anything and everything in our universe in tearm of mass and energy.But the same equation give birth to atom bomb.which can destroyed whole universe😥

by A. Einstein
My part in producing the atomic bomb consisted in a single act: I signed a letter to President Roosevelt, pressing the need for experiments on a large scale to explore the possibilities for the production of an atomic bomb.
I was fully aware of the terrible danger to mankind in case this attempt succeeded. But the likelihood that the Germans were working on the same problem with a chance of succeeding forced me to this step. I could do nothing else although I have always been a convinced pacifist. To my mind, to kill in war is not a whit better than to commit ordinary murder.
