Mechanism
Mechanism of The Black Hole Information Problem
Quantum fields near a black-hole horizon can produce Hawking radiation while partners and outgoing modes become entangled. Continued evaporation creates a tension between smooth horizon physics and preservation of quantum information, often expressed through the Page curve and entanglement arguments.

supported · checked Sep 22, 2026The issue is theoretical because astrophysical Hawking evaporation has not been directly observed.
supported · checked Sep 22, 2026The black hole information problem asks how quantum information is preserved when matter falls into a black hole that can eventually evaporate through Hawking radiation.
