Physicists may have found a new route into the black hole information paradox

Physicists recast Hawking radiation in particle-physics terms using the double copy method.

The calculation matched a scattering process in a collapsing charged electromagnetic background, without needing a real black hole.

Two other teams independently found similar results, strengthening confidence in the approach.

The work could make black hole evaporation and information loss easier to study and help bridge quantum physics with gravity.
