    Fusion is not some chain reaction that survives infinitely without end or fuel sources like some mystical magical wormhole into a nether dimension of pure power, like movies and tv shows seem to portray.

    It just stops working when it runs out of compatible fuel, the same as every other energy source.

    Just like the sun will eventually.

    The sun just has so much fuel available to it it literally powers the entire solar system just from the few degrees of radiation that hit a few space rocks. Like, it’s almost impossible to imagine how big and how much fuel the sun has at its disposal here.

    So much, that when it eventually runs out of fuel to continue to generate radiation in the way that sustains life, it still has so much mass/fuel available that it turns into one of the densest things known to mankind, preventing even light from escaping.

    Unless you know of a fuel source like that somewhere on earth, neither a mini-sun that blows up the planet, or a black hole that sucks in the planet, is ever, or will ever, be remotely possible.

    Science is science, not magic.

    Edit: to clarify with the correction below from Jax (thank you), our sun, in particular, will not be turning into a black hole. But other super-massive suns/stars will. So black holes aren’t even a thing possible in our entire solar system, ever. We simply don’t have enough mass, much less on earth.

      I don’t disagree with most of what you’ve said, but our sun will not be turning into a black hole. It would need something like 20x the mass it currently has.

        That’s correct, yeah, my apologies. I conflated it with supermassive stars/suns to make a point and didn’t clarify that it wont be happening to our sun, in particular.

        Thank you for the correction.
