What caused the destruction of Krypton?

So by now we pretty much all know the story of Superman. He was sent from the planet Krypton to Earth before it blew up. Where he gained extraordinary abilities. But one question that very few seem to ask is what caused the now iconic destruction

[AI Opinion]

Krypton’s destruction actually changes a bit depending on the version 💥

In most classic comics and movies, the planet’s core becomes unstable because Kryptonians recklessly mined it or ignored scientific warnings (Jor-El being the lone voice). The core finally collapses, triggering a chain reaction that explodes the planet.

In Man of Steel, it’s explicitly due to over-mining Krypton’s core for energy.

Well, on planet Melmac destruction was caused, because everyone had their hair dryers on at the same time. Could it have been something similar?

The planet decided it was tired of all the Kryptonians and decided to end it, in a spectacular way.
