Rethinking the Fermi Paradox: Black Hole Computing and the Search for New Technosignatures
To the point
Gia Dvali and Zaza Osmanov propose that advanced civilizations could run tiny, ultra-efficient quantum computers inside micro black holes, with Hawking radiation acting as a detectable signature, so technosignatures might be found in unusual infrared or optical emissions and even neutrinos rather than in large structures or radio waves.
