Dyson-like Energy Collectors Around Supermassive Black Holes: A Speculative Proposal Discussed at Dyson Minds 2025

To the point

Led by Olivia Curtis, Penn State researchers propose that an ultra-advanced civilization could harvest energy from a supermassive black hole by surrounding it with Dyson‑like shells about a parsec away, producing infrared signals detectable in data from M87 and Sagittarius A*, though Avi Loeb cautions that the near-hole environment would be extremely risky and prefers safer, distant locations.
