If no what can you find in outer space? Hydrogen? Oxygen?

If outer space is outside the boundary of the Universe is there a vacuum there?. I without proof state =no. The reason is that there must be something different than our physical space outside ithe Universe that holds the Universe in the shape we observe it to be..Since the geometrical space we live in is not a vaccum but has a substance in it which at one time was called aether is now identified as dark matter .This space substance being contained under pressure is the cause of all mass (Galaxy,solar system etc..)structure motion..This has to mean that the Universe has a boundary forming a restrain in the containment.Without this restain nothing would move.
We basically are able to observe our Universe and outside the Universe we have no scientific way of determining what keeps the Universe in equilibrium.
Vaccuum is defined as the absence of air. Just because there is no air it doesnot means that there is emptyness in a vauum. Especially when light rariation permeates throut the Universe at an average temperature of 3 degree k means a lot of free mass is floating around just like free electrons float inside a conductor.

No, there is no such thing as a complete vacuum. Space does contain a lot of hydrogen but another thing to consider are virtual particles in particle pairs.
The theory goes, in the presence of an absolute vacuum, two virtual particles will be created which are particle/anti-particle pairs. Almost immediatly the particles annihilate eachother.

No it's not. In outer space there are on average at least 1 to 2 hydrogen atoms per cubic meter.

Between galaxies is where you'll find the largest vacuums, but even there you will come across an atom floating here and there. Between galactic clusters there is an overwhelmingly, desolate, vacuum of nothingness, but still you occassionally come across a stray hydrogen atom. So, no, it is not a complete vacuum, laddy.

personally I cant tell you from experience but most of space according to what i have been taught is..Im not talking about the space around planets that have oxygen im talking about what you are calling outer space..blackness void..

it is vacuum ' example in space u r like a balloon , the air inside try to comes out and the space is so vacuum it will suck it up , that is Ur blood cuts open through skin and comes out ( high pressure to low pressure)

each action has an equivalent and opposite reaction... Its between the main elementary rules of physics. in case you push a paying for cart, what's relatively happening is that as you push the cart, the cart pushes back at you the two annoying. yet simply by fact the cart has wheels and you do not, the cart has much less resistance and as a result it strikes and not you. the comparable is authentic in area. yet on account that each thing in area is in simple terms floating, all gadgets have a approaches much less resistance than in the international. So in case you push a paying for cart in area, the paying for cart will push back and you will the two circulate removed from one yet another at a reasonably equivalent speed. once you leap in the international, you're pushing the earth removed from you and technically the earth does circulate, yet simply by fact it has a lots better mass than you, the quantity it strikes isn't sizeable. A rocket in area pushes gases out of the thrusters, the gases push back on the rocket interior the choice path inflicting the rocket to circulate.

No...
There are minuscule particles and matter (lots of 'dust' and simple gasses--though in very small densities). Even between galaxies this is true. Not to mention that space also contains particles such as photons.

We have no real way to test that out as we can't test each area of space, so it is possible that there may be small amounts of air in certain areas.

unlike the other outer spaces it doesn't lose suction
