This might be a brainlet questions but, can you build a structure strong enough to hold pure vacuum?

Is this what vacuum chambers do? Do they basically hold a vacuum comparable to open space?

From my understanding the hard part is keeping atmospheric pressure from crushing the chamber.

Some do, yes.

A vacuum chamber only has a pressure differential of 1 bar, which is essentially nothing. Actual pressure vessels must withstand hundreds of bars.

space isn't a perfect vacuum, space is filled with all sorts of crap, space has a small but significant average density.

yes, but only because pure vacuums don't physically exist
>Is this what vacuum chambers do?
yes
>Do they basically hold a vacuum comparable to open space?
they can, yes

there is less difference between the inside of your car or bike tire and the air around it than there is between that air and a pure vacuum
vacuum is harder for the same reason that balloons easily inflate and hold extra pressure but if you tried to pull the pressure out they would just collapse

Structures being able to hold vacuum are strong enough to hold pure vacuum, the hard part is achieving that pure vacuum, which is impossible.

>>13059917
Designing a strong enough chamber is not difficult, see >>13059999 Sealing and pumping down said chamber is difficult.
>Is this what vacuum chambers do?
You get rid of air and shit to be able to do stuff you couldn't in atmosphere, particle stuff, coating, drying, heat treatment ....
