Overview
Core model: The Black Hole Information Problem
The black hole information problem asks how quantum information is preserved when matter falls into a black hole that can eventually evaporate through Hawking radiation. A naive semiclassical calculation produces thermal radiation seemingly independent of the detailed infalling state, conflicting with unitary quantum evolution.

supported · checked Sep 22, 2026The issue is theoretical because astrophysical Hawking evaporation has not been directly observed.
supported · checked Sep 22, 2026Quantum fields near a black-hole horizon can produce Hawking radiation while partners and outgoing modes become entangled.
