"something called a pair-instability supernova"

Otherwise called a hypernova. The larger a star is, the hotter it burns. The core undergoes so much fusion of hydrogen to helium that there is an overabundance of gamma rays, and energy begins converting to matter again in the form of electron-positron pairs. This is an endothermic process which temporarily stalls thermal expansion, a necessary counterbalance to gravitational collapse. As the core begins collapsing, pressure spikes and all the hydrogen converts to helium at once, rather than slowly over time. The star explodes.

So you are saying the star exploded because of a stuck fart 😏 ?

I went out with a girl like that.

The star explodes.

Fusion reactors on Earth require creating supernova conditions. Is that really a good idea? Instead of meltdowns we might have to worry about whole mountains exploding into the sky.
