Could a Black Hole Orbiting a Planet Be a Sign of Advanced Civilizations?

Astonishing New Study Suggests How Advanced Civilizations Could Use Black Holes as Infinite Power Sources

• Scientists constantly search for signs of extraterrestrial life; the latest theory may involve black holes. A recent Harvard Professor Avi Loeb’s study proposed that advanced civilizations could use black holes to generate limitless power for their home planets. This theory builds on the famous 1971 concept by physicist Roger Penrose, who suggested that energy could be extracted from a black hole’s accretion disk. Researchers have explored using black holes as energy sources in the decades since, pointing to their incredible potential.
• In his recent paper, Professor Loeb suggests that an advanced civilization could use a small black hole orbiting their planet, providing endless energy through Hawking Radiation. Such a system could be detectable light-years away, offering a new potential technosignature for future space research.
• The concept is theoretical but opens exciting possibilities for discovering alien civilizations. Loeb describes this black hole system as the most efficient engine ever conceived, converting fuel into energy with 100% efficiency — an achievement impossible with any technology currently available to humanity. Waste materials could even power this black hole, solving energy and environmental challenges.

Loeb’s innovative idea brings us closer to solving the Fermi Paradox and searching for civilizations beyond our solar system. Detecting a planet illuminated by a black hole-powered moon could be our first glimpse of an advanced extraterrestrial society.
