If somehow i brought a steel tube into space and had a lever in it to push out all the air then i sealed the tube (if this is even possible) what would i have in it? What would happen if i tried to breath what was inside?

What you would have in the tube would be an almost total vacuum (the interstellar vacuum is misnamed; there are particles of dust, hydrogen molecules and so on out there). However, it's still enough of a vacuum to turn your lungs inside out if you tried to breathe through the tube...depending, of course, how big of a tube it was.

You wouldn't need a "lever" in space, all the air would rush out anyway.
And we can make vacuums with less gas density than interstellar space in a laboratory.
But we're still trying to figure out what makes a certain space "space". If you move the tube into the atmosphere, is the same empty space inside the tube and air rushed around it to fill in the space it left behind, or is it that the vacuum tube and the air occupy different space as they change position?
Another interesting thing to look up is zero-point energy, the energy necessary to maintain a volume of space.
UFO freaks say flying saucers run off the stuff, but it seems like such a power source would leave the ship with no place to go!

You would have a vacuum (or very nearly). There would be no molecules of any kind, and so nothing to breathe. If you brought this steel tube back to Earth, all the air pressure here would be trying to fill that vacuum, so if you started to open it, air would rush in and fill it before you could possibly try to breathe any of it.

Just use a vacuum pump and a bell jar. You'll get the same "space" in there. Space is a term to define volume. You can't capture a vacuum. To create a vacuum, you would remove all the matter and gases from the "space".

It would be full of space.
As you moved it about the space would be displaced by more space but no matter what you did it would always contain space.
If you laid it under a steam roller it would be flattened and all the space would be displaced from the inside

Not that any of us are suggesting you try to breathe in a vacuum.

there would be no matter in the tube.. a vacuum
