Together with Brandon Carter and Jim Bardeen, Hawking wrote a paper, published
. . . . .
. . . the team commented, '' In fact the effective temperature of a black hole is
absolute zero . . . No radiation could be emitted from the hole.''

/ Book: Stephan Hawking, A life in science,
by Michael White and John Gribbin, page 156./

Later, using concept of entropy and Heisenberg uncertainty principle,
Hawking changed his mind and wrote that black hole can emit
( Hawking radiation )
