8 Scientific Theories That Totally Change Captain America: Civil War

2. Iron Man

Iron Man's suit is definitely cool, but it would also be incredibly hot.

Attaching powerful jet thrusters to his extremities should turn Tony Stark into a boil-in-the-bag billionaire in a matter of minutes. This obviously doesn't happen, so the suit is obviously dealing with this heat somehow. It would make the most sense to convert it into electricity and using it to power the on-board computer systems, much like a car uses the heat from its brakes to charge the battery.

This, however is only half the battle, as the forces exerted on Tony during an epic battle between good and evil should by all rights reduce him to scrambled eggs.

The suit can travel at incredible speeds and a sudden change in direction, like the ones Iron Man so often performs, would leave him with a severe concussion at the very least. Just like in a real-life car crash or boxing match, Tony's brain would slosh around inside his skull like a blancmange and suffer some pretty extensive damage.

One possible solution is that the suit contains a special dampening layer just like the fluid that surrounds the brain, in order to take the sting out of the sudden twists and turns.
