Now I am starting to understand why superheroes defy physics on a daily basis. Real science really limits what your heroes can do, which is ESPECIALLY frustrating when your making superheroes of your own.
Case in point, I made a heroine who generates her own oxygen out her lungs and has a has fire shield that is 2 inches off her body/costume. I thought that maybe she could fly thanks to the oxygen and fire creating thrust...well real science stopped me:
Oxygen is a non-combustible gas. This is very confusing to a lot of people, because television and movies rarely get it right. Oxygen will not burn, and will not explode when exposed to a spark or ignition source. After all, combustion is the exothermic process of adding oxygen to a substance at a very high rate. What would be the reaction equation of burning oxygen? O2 + O2 -> 2O2? That isn't a reaction.
Now, oxygen is necessary for combustion of other materials, and the higher the partial pressure of oxygen you have, the faster that reaction will progress. So a person's clothing, if saturated in a high partial pressure of oxygen, will ignite more easily and burn hotter and faster than it would with only room air. Under sufficient O2 partial pressure, some materials will spontaneously combust, or may change from fire resistant to being readily combustible. That's why you don't use petroleum products on oxygen O-rings, and you shouldn't smoke in an oxygen tent. The oxygen won't "catch on fire" but your clothing, the tent or the bed linens may, and with great enthusiasm.
So now I have the choice of:
A: Change my character's powers to allow her to fly in another manner (annoying to say the least). Or...
B: Willingly ignore the laws of science and take my rightful place among the greats of comic fiction LOL.
Oxygen makes fire burn better but it does not explode, it only does that when combined with other gases.
So unless I make her breathe hydrogen and oxygen...man that would lead to some weird complications. My head is about to explode LOL (yes I did do a bit of research, yahoo questions thanks).
