    Think of what the night sky would look like if this giant went supernova.
    Probably would leave behind a black hole.

    The light we see now left Betelgeuse about the time the Black Death was wiping out more than half the population of Europe. I guess we'll find out eventually if anything's happened since.

    That is not really that far away considering the vastness of space.

    Google says Betelgeuse is about 642.5 light years away from Earth, would we notice any repercussions if and when it goes supernova?...

    Nope the shock wave will have disappeared by the time it reaches us.

    The orion system has a very close meaning to me as it resembles my late father's golf swing to a tee. Slight reverse pivot was his only weakness and is present, betelgeuse is his head, to which I nod at every time I see it with a few words.

    The bigger the star the bigger the resulting explosion.
    This would go from simple nova to the super-nova class, possible leaving behind a black hole.
    Would the x-rays and gamma-rays be dissipated to safe levels by the time it reaches us is the question.

    It's enough to make you feel like a moth.

    We would be so lucky to see such a show but highly unlikely to happen in our time. It's stated a few million years for a star to die, under a quarter a second for it to collapse, a few hours for the shock wave to reach the surface, a few months to brighten and a few years to fade.

    We have a ten billion year bulb and exist on a twelve billion year ball and no one knows when the light was switched on.

    Experts claim we aren't being pulled in but the think we are. Takes so long there is no term for it yet and if the star has the right timing and size it could use the planets as fuel. Pulling everything in with the intent of accumulating maximum matter to reseed the optimum amount.

    Nature works on that basis here and it just feels right to think maximising chance would follow suit out there.

    Most failing but enough succeeding.
