| Apr 25, 2014 at 12:29 | comment | added | Gerald | @Py-ser Take vacuum as space filled with the lowest possible energy, call this energy zero. By Heisenberg's uncertainty you'll get electromagnetic quantum fluctuations of any wavelength. Between two metallic plates longer wavelengths don't occur, reducing the energy contents below zero, the result is negative energy. Zero energy outside the plates excerts a pressure in comparison to the negative energy between the plates. | |
