[00:00:00]Every black hole in our universe is secretly a ticking time bomb. They look like eternal graveyards, but they are actually the universe's final hourglass, slowly bleeding away through a strange whisper called Hawking radiation. For most of history, scientists believed black holes were perfect prisons.

[00:00:17]Anything that fell in, even a beam of light, could never come back out. But in 1974, Steven Hawking shattered this idea with a stunning discovery. He mixed quantum physics with Einstein's gravity and found that black holes are not totally black. Empty space is not really empty. Tiny pairs of virtual particles constantly pop in and out of existence.

[00:00:38]Sometimes one partner falls into the black hole while the other escapes forever. To balance the energy books, the black hole must give up a tiny piece of its mass. Drop by drop, the giant leaks. This slow bleeding is the entropy
