If you could create a perfect vacuum (no atoms or molecules of air or anything at all) inside a vessel , and assuming it's sitting in earth's normal atmosphere, there would still be only ~15psi attempting to crush the vessel. You can't draw a vacuum lower than that. And the vacuum would register on a guage as approx -15psi.
I'm not sure minus 10000 psi has a meaning. Can you make a vacuum that's a harder vacuum than a perfect vacuum?

I used pistons to pull a vacuum, not a pump. I was thinking last night,
I've imploded a few cylinder walls by pulling too hard, or too fast.
I haven't studied the issue, I moved on to other things, but it does
fall in line with how much of a vacuum can be pulled on a, say, 2,000
PSI rated piston, drawing against something, using a lever on the
piston, getting, in theory, several tons of draw.
At what point does "air", or lack there-of, fail, or get squirrely?
At what point does the chamber itself attempt to become a singularity?
~15 psi from the outside is one thing, and the best we'll ever get.
What about -10,000 from the inside?
Might be something to play with again in the future, as there some ideas
I have.
