Well, I mean, the sun’s not *that* hot. I mean, it’s a star, obviously, and its core temperature is like 15 million degrees. But in terms of the highest measurable temperatures, that’s nothing. The hottest known phenomenon anywhere in the universe actually occurs in Switzerland. Experiments in the Large Hadron Collider can reach like 5 trillion degrees C.
Stars are hot, and they’re remarkably big and remarkably long-lived. But they’re a long, long way from being the hottest phenomenon that exists.
