It would also be physically impossible I’m pretty sure, to completely remove every single particle from an enclosed volume, as the more you remove, the harder it becomes to remove more? I dunno I’m not an experimentalist.
That’s setting aside that even if you did somehow create a perfect vacuum in a box, you would then still have all the quantum fields permeating the box, some of which I guess would creat and annihilate virtual particles inside there continuously. A box that can block quantum fields would be truly impressive. Not sure what the hell you’d do with it but… it’d be a neat conversation starter :P
At some point you run into the issue of virtual particles: Matter-antimatter pairs that arise from the intrinsic energy in any space, popping into existence for an unimaginably short time before turning back into energy, happening everywhere in the universe uncountable times per second.
The actual reality of a virtual particle is a bit of an open question though from my (admittedly limited) understanding. They seem to just be a figment of the maths required to arrive at the on-shell processes. A guy I spoke to recently was rather dismissive about a particular area of research as they don’t really bother with interactions that lead to external particles. Like “Oh we can calculate gg -> gggg scattering super-duper fast compared to the old methods!” “Great, how does that help us exactly?”
If they can hold a perfect vacuum, aka truly NOTHING, then that’d actually be something worth paying for.

Aye, I mentioned them in my second paragraph :D
