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 ...
