how come there aren't any air molecules in outer space?

Question

I mean, like why isn't there any air/oxygen in our solar system? what is the reason?

Answer 1

The conditions of space are unfriendly to air's existence. The vacuum pull them apart clear down to atoms because of instant dispersion into a huge area, turning the molecules into unrecognizable atoms, and the atoms disperse, nothing left to exist. On earth, we can create nearly a vacuum, but not completely. Space has a perfect vacuum. Gasses disperse so widely that they aren't recognizable as whatever they started out being. If you were shot out into space unprotected, the same thing would happen to you. Instant and total destruction by boiling and freezing simultaneously, exploding into billions of tiny molecules which explode into atoms in less than 1 second. It would be an awful thing to see.

Answer 2

Because it wouldn't be space if objects were there to fill it. ; )

Why ask why? Science is NOT about asking why. Science is about describing things, or lack thereof, as they are, accurately.

Actually "Outer Space" has lots of things in it...the Earth for one. The Sun is a nuclear furnace of Hydrogen gas. It emits a Solar Wind that is a plasma (Gases stripped of their electrons) The DENSITY is not large compared to that of the Earth's gases. But there are gases in Interplanetary space.

Now the arms of the Milky Way galaxy are loaded with gas and dust. But it is not very dense. It is less dense than that of Interplanetary space. That is called Interstellar space.

Do you want to see some Interstellar Oxygen? Tomorrow night take a look for the constellation Orion. Look for the club that swings beneath his belt. The second brightest "star" upward (towards Orion's belt) of that club is not really a star at all. It is a Nebula, a cloud of gas. It is The Great Nebula in Orion. If you locate that "star" you'll be looking at some Interstellar Oxygen.

Now Intergalactic space is less dense than Interstellar space. But there still is some gas and dust. "Outer Space" is not a perfect vaccuum. Otherwise, you and I...well...we wouldn't be here. We fill some of the space, right?

Answer 3

there is not any air... per se.
there's a lot of oxygen but there is a huge space an it's not dense enough to be good to breath, it's some sort of paradox that space contains the universe but still is so empty that makes a vacuum that makes impossible to breath even when there is a lot of oxygen

Answer 4

The reason is that because of all the black holesi n space when space was first "created" as most people would say all the black holes (which there are over 500,000 of them in our universe) sucked up all the air and the atmosphere in our planet and the ozone layer of ours protected us from these black holes and the fact that not many are near our planet

Answer 5

Because space is a vacuum, so air would chemically separate and drift away. Air (nitrogen, oxygen, etc) is confined in Earth's atmosphere under the forces of gravity.

Answer 6

All matter attracts and tends to cling together. The force that causes this is gravity. So when there are swirls of gases in space, they immediately move towards planets, rocks and large objects as they attract them with gravitational force. So if any air did manage to appear, it would start moving towards more matter.

However in reality, there ARE small amounts of gases present in space. Its just that its such a small quantity - all the larger quanities clump together and/or move towards bodies that have the greatest gravitational forces on them.

Answer 7

in actual actuality that we did no longer realize it, a minimum of no longer for particular. in the previous we actual have been given up there, the main shall we do is arise with theories approximately it, and desire that our theories weren't disproven via different scientists. yet, the 1st theories with regards to the airlessneess of area began as scientists began to be conscious that there is a vital substitute in air stress the better in altitude we bypass, that places the place the earthe is under sea point have greater air pressures than places that are at sea point, that's greater than any factors on up the aspects of any mountains. So, the thought all began that in the time of a few unspecified time interior the destiny, air stress might attain 0.00 psi, (kilos consistent with sq. inch, which additionally happens to be the suitable comparable measurment in kilograms consistent with sq. meter, yet, the metric equipment did no longer actual exist some time past then...) and that stands out as the definition of an airless entire vacuum of area. the reality, inspite of the incontrovertible fact that, is that there are measurable parts of loose-floating molecules of hydrogen and helium and nitrogen in outer area, so even nevertheless the stress could be measurable in terms of micrograms consistent with sq. terameter, there is air in area, only no longer adequate for many forms of existence as all of us realize it to stay to tell the story in.

Answer 8

Actually, there are. There just aren't very many of them and they're fairly far apart. (maybe one every cm or 2) When you get into deeper space (between stars) that goes down to every few meters (unless you're in a gas cloud, in which case it might only be a few mm between molecules). When you get into intergalactic space, it may be several km between molecules.

Answer 9

Gravity. All matter attracts other matter. Most of the gas molecules have been attracted by the larger bodies in the universe.

Answer 10

There is some, but the particles are extremely far apart. The answer is that the vast majority of matter has collected into stars and some into planets.
