The Unreasonable Efficiency of Black Holes

The video explores the concept of mass-energy equivalence, illustrating how mass can be converted into energy. It discusses the inefficiency of chemical and nuclear reactions in energy extraction compared to antimatter and black holes. Antimatter offers 100% efficiency but is impractical due to scarcity. Black holes, especially rotating ones, provide a more feasible method, converting up to 42% of mass into energy. The video explains how accretion disks around black holes facilitate this conversion, making them the most efficient known method for mass-energy conversion.
