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.

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.

**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.

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.
