Why black holes are the universe's ultimate energy converters
In short: From chemical fires to nuclear fusion, most processes struggle to turn mass into energy. This video explains why black holes represent a level of efficiency that leaves almost every other known reaction in the dust.
The video explores the conversion of mass to energy as defined by E=mc^2, comparing different physical mechanisms. While chemical reactions like explosions are highly inefficient and antimatter is extremely efficient but rare, nuclear fission and fusion fall short of peak performance on an absolute scale.
Black holes—specifically non-rotating Schwarzschild and rotating Kerr types—stand out as the most efficient engines in the cosmos. This is due to their accretion disks and the remarkably small radius of their innermost stable circular orbits.
