You’ve probably heard that black holes stick around for a long time—but even they are not eternal. Over unimaginable spans of time, they slowly evaporate into space through a process called Hawking radiation. And here’s the kicker: this doesn’t just apply to black holes. Anything with mass—stars, moons, even you—can, in theory, evaporate in this way. Black holes are a special case since they don’t have a surface and can actually swallow some of their own radiation, making their demise painfully slow. The biggest ones might take up to 10^100 years to disappear. But smaller objects? Something like the Moon—or a human being—could fade into nothingness in
