Robin, You only answered 2 of my 7 questions! Don't be shy... :-) -Mark GIVEN: Two Casimir cavities, C1 and C2, with plate spacings of d1 and d2, respectively, and d1 *NOT* equal to d2 so one Casimir cavity excludes more wavelengths of virtual particles than the other, then there would be a difference in some kind of property between C1 and C2 (ED1 and ED2; ED=energy density).
QUESTIONS: - ANSWERED: Can that difference be thought of as a kind of pressure? - ANSWERED: How would you measure that pressure? - Would that pressure diff cause some polarization of the vacuum? And more importantly, - If you 'connected' one of the plates of C1 to one of the plates of C2, would you get some kind of 'flow' (of something!) between them? (A flow of electrons or virtual particles perhaps?) - If a flow of virtual particles can occur, then what would you use to connect C1 to C2? - Would it be a continuous flow since you probably can't deplete the vacuum? - Can you equate various aspects of atoms (I'm thinking physical spacings) as Casimir cavities with different spacings (after all, there is only vacuum between subatomic particles), and thus the above situation is present everywhere, and there are continuous flows of vacuum going on within atoms/nuclei? -----Original Message----- From: mix...@bigpond.com [mailto:mix...@bigpond.com] Sent: Sunday, July 29, 2012 2:59 PM To: vortex-l@eskimo.com Subject: Re: [Vo]:FYI: Polarizable vacuum analysis of electric and magnetic fields In reply to MarkI-ZeroPoint's message of Sat, 28 Jul 2012 23:47:22 -0700: Hi, [snip] > - Can that difference be thought of as a kind of pressure? > - How would you measure that pressure? I think you have hit the nail on the head. Pressure is an energy density, so if you can calculate the latter, then you also know the former. There already exists a formula for Casimir energy based on plate spacing, so it shouldn't be too hard to calculate the energy density and express it as a pressure.
