WebMar 14, 2024 · Hawking radiation means the black hole is losing mass. But we have no idea what that means for the pizza, which, presumably, is still inside the black hole. It’s a scientific mystery that ... Hawking's discovery followed a visit to Moscow in 1973, where Soviet scientists Yakov Zel'dovich and Alexei Starobinsky convinced him that rotating black holes ought to create and emit particles. Even still, Russian physicist Vladimir Gribov believed that even a non-rotating black hole should emit radiation. Hawking would find this to be true once he did the calculation himself. In 1972, Jacob Bekenstein conjectured that the black holes should have an entropy, where by the same … the world evolutions
