The Thorne–Hawking–Preskill bet was a public bet on the outcome of the black hole information paradox made in 1997 by physics theorists Kip Thorne and Stephen Hawking on the one side, and John Preskill on the other, according to the document they signed 6 February 1997, [1] as shown in Hawking's 2001 book The Universe in a Nutshell .
Mar 3, 2021 · In 1974 Stephen Hawking and Kip Thorne placed a bet on whether Cygnus X-1 was really a black hole. The wager was settled in 1990, but the world’s first black hole is still a mystery.
Mar 20, 2018 · Hawking bet another theorist, Kip Thorne of the California Institute of Technology (Caltech) in Pasadena, that Cygnus X-1 was not a black hole, with the prize being a magazine subscription. Hawking explained in his 1988 bestseller A Brief History of Time: From the Big Bang to Black Holes that the bet was a sort of “insurance policy” for him.

Black hole information bet. Whereas Stephen Hawking and Kip Thorne firmly believe that information swallowed by a black hole is forever hidden from the outside universe, and can never be revealed even as the black hole evaporates and completely disappears, And whereas John Preskill firmly believes that a mechanism for the information to be ...
Cygnus X-1 was the subject of a friendly scientific wager between physicists Stephen Hawking and Kip Thorne in 1975, with Hawking hoping to lose. Hawking bet that it was not a black hole. He conceded the bet in 1990 after observational data had strengthened the case that there was indeed a black hole in the system.
