Black holes turn out to be not just bottomless pits but genuine “libraries”—the information they swallow alters their vibrations. The “memory burden” parameter lets us read a hole’s past from gravitational waves. This bridges the quantum world with cosmic scales.
🎯 One square centimeter of a black hole’s surface could hold an amount of information comparable to the contents of a billion libraries.
🎬 The idea of a black hole as an information repository is familiar from the movie Interstellar, where the protagonist transmits data through a singularity.
