As a little nitpick, “extreme pressure” is partially true. We do need “extreme” pressure; not extremely high pressure, but extremely low pressure. We have these series of pumps that are able to remove more and more particles at each step. We have your standard pumps that get rid of most gases, then we have turbomolecular pumps that blow away a lot of the matter that remains, and then we have things like ion pumps, which electrocutes molecules in a vacuum and sucks them out using electric fields. This way, we’re able to create better vacuums here on Earth better than Space itself.

And honestly, that’s pretty much wizardry to me.
Won’t anyone think of the molecules!
Huh, I always thought my chamber is way worse vacuum then space (usually about 2×10-10 mbar)
