Can you breathe in space?

Question

I know sci-fi and machines and all that have said we can't survive in space.

So here's the question, how do we know? Our machines say it's not breathable? Has any creature ever TRIED? Or are we just guessing?

If this is true.... all we know about space may just change.

Answer 1

In outer space, uh-uh.

You need air to breathe. There's no air in outer space. To breathe air in outer space we need to bring/make our own.

Answer 2

If you have an oxygen tank.

Answer 3

1.  You're breating right now aren't you?  I

2.  We know how lungs work. Without air, they don't work.  

Answer 4

OMGURRITE We've never tried breathing in outer space! We for totally don't know that we can't! But what brave souls will be the first to discover whether we can or can't breath in the so-called "vacuum" of space - I nominate death-row prisoners.

Answer 5

there's no oxygen in space :P.

Answer 6

i can't, but i know in the world has only one human can stay in outer space.

Answer 7

You would explode without a spacesuit on. There's machines and stuff.

Answer 8

How long can a human live unprotected in space?

If you don't try to hold your breath, exposure to space for half a minute or so is unlikely to produce permanent injury. Holding your breath is likely to damage your lungs, something scuba divers have to watch out for when ascending, and you'll have eardrum trouble if your Eustachian tubes are badly plugged up, but theory predicts -- and animal experiments confirm -- that otherwise, exposure to vacuum causes no immediate injury. You do not explode. Your blood does not boil. You do not freeze. You do not instantly lose consciousness.

Answer 9

Space is almost a perfect vacuum. This means there is almost no "air" at all. There is definitely no oxygen. The "air" in space is so minor, that we can barely detect it even with the most sensitive machines. No one is going to try, but your free to do it yourself.

The simple Truth is, because the air isn't even close to being close to being as dense as the air on Earth, we wouldn't be breathing anything in. And like I said, there is not even the slightest trace of oxygen.

We aren't guessing, and even if we were, is that a chance you really want to take? And space is so cold that you would die before you got even take a sniff. And the pressure change would cause you to almost instantly explode, and obviously die.

Anything that you would breath in would be so cold that your lungs wot crystallize.
