And without that there wouldn't be any wavelengths (or virtual particles) inside or outside those plates and the Casimir Effect would not exist. * *John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* 6tc -- You received this message because you are subscribed to the Google Groups "Everything List" group.
