Black hole information paradox. The first image (silhouette or shadow) of a black hole, taken of the supermassive black hole in M87 with the Event Horizon Telescope, released in April 2019. The black hole information paradox[1] is a paradox that appears when the predictions of quantum mechanics and general relativity are combined.
Black hole complementarity. Black hole complementarity is a conjectured solution to the black hole information paradox, proposed by Leonard Susskind, Lárus Thorlacius, John Uglum, [1] and Gerard 't Hooft. [2][3]
The question whether information is truly lost in black holes (the black hole information paradox) has divided the theoretical physics community. In quantum mechanics, loss of information corresponds to the violation of a property called unitarity , and it has been argued that loss of unitarity would also imply violation of conservation of ...
Stephen Hawking provided a ground-breaking solution to one of the most mysterious aspects of black holes, called the "information paradox." Black holes look like they 'absorb' matter. Every time a ...
The holographic principle resolves the black hole information paradox within the framework of string theory. [5] However, there exist classical solutions to the Einstein equations that allow values of the entropy larger than those allowed by an area law (radius squared), hence in principle larger than those of a black hole.
John Preskill. 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 ...
Scientists say they solved the Hawking information paradox, which states that information can neither be emitted from a black hole or preserved inside forever.
Thus, information is never lost. This has implications in the black hole information paradox and in fact any process that tends to lose information completely. The no-hiding theorem is robust to imperfection in the physical process that seemingly destroys the original information. This was proved by Samuel L. Braunstein and Arun K. Pati in 2007.
