True negative vacuum pressure possible?

Postby Otvorgan » Fri Mar 18, 2016 8:46 am

I understand that the total pressure of a vacuum is 0, and that a gauge reading is just the difference in PSI and such between atmospheric pressure and the vacuum.

What I'm trying to find out, has anybody discovered a way to make the 0 pressue of a vacuum actually go negative? This is probably more of a quantum physics question. Or are there at least any promising theories?

Hi Otvorgan,

Is your question related to a K-12 science project? If so, what is the hypothesis you are trying to test? If your project is not related to a K-12 science project, then a different set of online forums will be better able to help you. These particular forums are devoted to helping K-12 students, parents, and teachers who are working on science projects.
All the best,
