L'effetto Unruh prova l'esistenza dei fotoni virtuali?
http://en.wikipedia.org/wiki/Unruh_effect
<<The Unruh effect, described in 1976 by Bill Unruh of the University
of British Columbia, is the prediction that an accelerating observer
will observe black-body radiation where an inertial observer would
observe none. In other words, the background appears to be warm from
an accelerating reference frame; in layman's terms, a thermometer
waved around in empty space will record a non-zero temperature.>>
