What would life be like if humans could breathe in space?

Asked by shpadoinklesue (52 points ) August 10th, 2014 from iPhone

Someone awesome, @ibstubro, suggested I ask this, and I’m glad they did. I’ll admit, I know little of the science involved. So, I’ll keep it simple. What differences would there be if we didn’t need a breathing apparatus or had something a little more Starlord-esque to play with.

This might become a standard way to get around.

Human wouldn’t worry about global warming, polution, meteor attacks… anymore.

Or maybe the space would be poluted instead.

Speed would become of paramount importance. If we didn’t have to worry about sustaining an Earth-like environment in space, out goal would be some place else, fast. Humans would want to begin raping and pillaging our solar system ASAP, with an eye toward reaching other systems as soon as possible.

No different. They’d still have to get up there, maintain orbital speed or continue to match the speed of gravity and not fall back to Earth. And in so many places it isn’t just the air or lack of it, it is the extreme temperature in sunshine and/or shade, and solar radiation/sunburn.

I say not very different. It’s not like getting into space and back is easy with today’s technology.

Sorry, but this question is super-broad and it only has me imagining endless reasons why not and other smarty responses.

They’d need one less piece of equipment on space walks. Unless the reason was that there was actually air up there, in which case… the universe and/or physics would be very different, or else, for example, we’d be crushed by the weight of all the air above us.

If it was just that we didn’t need air, then our astronauts would still die of cold and radiation and lack of pressure up there, unless we had suits, so not much difference. In other words, not having air to breathe is only one of the relatively minor barriers to doing things in space.

If you just want help to fantasize about people flying around in the sky doing fantastic stuff, maybe watch the 1980’s film Flash Gordon which has hawk men flying around and stuff, and a hilarious theme song.
