The Casimir Effect as a Possible Source of Cosmic Energy
  Energy production due to the Casimir effect is considered for the case of a superdense state of matter, which can appear in such cosmological objects as white dwarfs, neutron stars, quasars and so on. The energy output produced by the Casimir effect during the creation of a neutron star turns out to be sufficient to explain nova and supernova explosions. It is shown that the Casimir effect might be a possible source of the huge energy output of quasars.
