You Know That R.E.M. Song, ‘It’s The End Of The World As We Know It’? Ahem.
It’s not hyperbole to talk about having the end of the world at our fingertips. It’s right here, folks. If we thought Hiroshima and Nagasaki were huge and horrifying, imagine what it would be like if we detonated something on a country like the world has never seen. Something 1,000x as powerful as the ones we detonated on Japan. Because that is the size of the last bomb the USA tested. Yay, us?
To put it into even better perspective, I've zoomed it out for you here:
It's worth noting the largest ever detonated was called Tsar Bomba, by the Soviet Union, which was 50,000 kilotons, or 3x the power of Castle Bravo.
