8 hours ago If black holes withheld information forever in their singularities, there would be a fundamental flaw with quantum mechanics. The significance of the information paradox came to a head in 1997 when Hawking, together with Kip Thorne of the California Institute of Technology (Caltech) in the US, placed a bet with John Preskill, also of Caltech.

8 hours ago The Most Famous Paradox in Physics Nears Its End. By George Musser. October 29, 2020. In a landmark series of calculations, physicists have proved that black holes can shed information, which seems impossible by definition. The work appears to resolve a paradox that Stephen Hawking first described five decades ago. 81.

Frequently Asked Questions

What is the black hole information paradox?

Artist's representation of a black hole. The black hole information paradox is a puzzle resulting from the combination of quantum mechanics and general relativity. Calculations suggest that physical information could permanently disappear in a black hole, allowing many physical states to devolve into the same state.

What is information paradox?

Information paradox is the short form for two paradoxes: This disambiguation page lists articles associated with the title Information paradox. If an internal link led you here, you may wish to change the link to point directly to the intended article.

What is information loss paradox?

This is the information loss paradox. It is a paradox because it is assumed that all fundamental dynamical processes are time-symmetric – in particular, in quantum theory, that the dynamics is unitary. Information can never be lost by such processes.
