Pacific Rim probably had a checklist. Giant robots with giant swords, guns, and rocket arms? Check. Giant monsters with giant claws, teeth, and acid spit? Check. And if all that rock ‘em, sock ‘em goodness wasn’t enough, the movie concluded with two massive nuclear explosions. One was so big that it literally turned a part of the ocean bottom into dry land before caving in on itself. Having a robot with future-strength muscles is something we can forgive to keep the movie rolling (it would take something like 1,000 Bugatti Veyron motors just to lift a jaeger arm), but nuclear blasts are something we know a lot about. Since the 1950s we have gone atomic with the equivalent of 500 million tons of TNT to figure out just what happens.
It begs the nerdy question: How big would a jaeger bomb have to be to create dry land on the bottom of the Pacific Ocean?
