@shoortdose: What's the biggest bomb humans could ever build? Not the Tsar Bomba. In 1954, Edward Teller pitched Sundial: 200 times stronger, a fireball wider than the horizon, and loud enough to be heard on the other side of the planet. 💣 Send this to the friend who thinks the Tsar Bomba was the biggest. Which part got you: the 400 km of fire, or that we built one Sundial anyway? #nuclear #coldwar #History #Science #sundial
