The ultimate film about weapons of mass destruction On July 16, 1945, at a site called Trinity, a plutonium bomb was assembled and brought to the top of a tower. The bomb was detonated, producing an intense flash and a fireball that expanded to 600 meters in two seconds. The explosive power was equivalent to 20 kilotons of TNT. It grew to a height of more than 12 kilometers, boiling up in the shape of a mushroom. Forty seconds later, the blast of air from the bomb reached the observation bunkers, along with a long and deafening roar of sound.
This Guy's Portal Gun Actually Works, Turns His House Into a Test Chamber
Not necessarily, once he flew into the air all of his earlier momentum was slowed, then halted, by gravity, then it was simply a matter of falling from that height... he would have gone very high up, but on his way down I don't think he would reach terminal velocity again (napkin math tells me it would be less, but I don't know how much less). Even if it were substantially less, it *would* have killed him anyway, *if* all of that force was directed toward the Earth when he landed, but as soon as he went through the last portal, all of that gravity was transferred into horizontal force, and (like a bullet) he would have fallen to Earth no faster than if you dropped a baseball. That said, in the video it looks like he slammed into that fence, so... The solution would've been to put two portals on the ground and wait for gravity to slow his velocity as he fell up and down through both. Of course, I imagine that the shifting gravity would cause you to vomit. That section had a few problems...
