Book: ''' Stephen Hawking. A life in science ''
''Together with Brandon Carter and Jim Bardeen, Hawking wrote a paper,
published in Communications in Mathematical Physics , pointing out . . .
the team commented, '' In fact the effective temperature of a black hole
is absolute zero . . . . No radiation could be emitted from the hole.''
/ page 156./
But later (!) , . . using concepts of entropy and Heisenberg uncertainty
principle and quantum fluctuations (!) Hawking changed his mind
and wrote that black holes can radiate.

So, in the beginning ( according to calculations) the ''black hole''
had absolute zero temperature (like the Cosmic Vacuum: T=0K) . . .
but . . . thanks to entropy, Heisenberg uncertainty principle and
quantum fluctuations the absolute zero temperature was changed.
Cosmic Vacuum and black holes are one and the same system.
Black holes are parts of the infinite Cosmic Vacuum.
