What’s entropy like inside a black hole? And how do we know that black holes have entropy in the first place? Jacob Bekenstein suggested that the area of a black hole was itself a measurement of its entropy. But if black holes had entropy, they would have to emit radiation (which was thought impossible at the time). In 1973, Stephen Hawking ran calculations that showed that black holes would indeed create and emit particles. Keep reading to learn more about black hole entropy.
