Dyson Spheres Around Supermassive Black Holes: A Speculative, Cross-Disciplinary Exploration of Black-Hole Power
To the point
Olivia Curtis and colleagues propose a speculative idea that ultra-advanced civilizations could build Dyson-like megastructures around supermassive black holes to harvest accretion and jet energy, about a parsec away to avoid vaporization, with infrared signals as a potential signature, though Avi Loeb cautions the environment around active black holes would be extremely hazardous.
