Affirmative. The theory appears to have some problems, though.
The theory predicts that the total zero point energy in the vacuum to be
infinite when summed over all the possible photon modes. The energy of the
vacuum should act gravitationally and produce a large cosmological constant
which would cause space-time to curl up.
Anybody cleared up this inconsistency yet?
