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.
It's entitled Black Hole Entropy and Soft Hair, and it tackles the black hole paradox. According to Hawking's co-author Malcolm Perry, the paradox "is perhaps the most puzzling problem in ...
In quantum information, the Hayden–Preskill thought experiment (also known as the Hayden–Preskill protocol) is a thought experiment that investigates the black hole information paradox by hypothesizing on how long it takes to decode information thrown in a black hole from its Hawking radiation.
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.
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.
Stephen Hawking’s suggestion that black holes “leak” radiation left physicists with a problem they have been attempting to solve for 51 years.
Netta Engelhardt is an Israeli-American theoretical physicist known for her work resolving the black hole information paradox, concerning the apparent loss of physical information from objects that enter black holes and become transformed into Hawking radiation. [1]
