Second supermassive black hole is a long way from the galaxy’s core.

    Ugh. Hate when that happens.

    Remember: This could happen to us and there’s nothing we could do about it

      It’s theoretically possible, sure, but the nice, pretty spiral arms that our Milky Way has indicates it probably hasn’t crashed into any other big galaxies recently. So we probably don’t have any rogue supermassives, just rogue normal ones which are much harder to detect.

        You would think we’d see the gravitational influence long before one comes near, however.

          You mean with an unexplained orbit of Neptune? The reason we can’t find planet 9 may well be because it’s actually a black hole

      We just have to keep a look out for something totally black in the sky.

      I choose to forget that, if it’s all the same to you.

      Wouldn’t time dilation essentially put us in a frame of reference that ffwds to the end of the universe?
      Or would gravity waves tear us apart before we could experience that?

        Gravity would shred everything way before you noticed any cool time dilation effects. If somehow you became invincible, you still wouldn’t see a fast forward movie of the universe, the light falling into the black hole also experiences distortions and becomes so blueshifted that you could not “see” anything. Outside observers also could not see you or anything else slow down on approaching the event horizon. Any light emitted from an infalling object becomes so redshifted, the ability to observe an infalling object fades away extremely quickly and is not infinite.

      I guess this depends on the mass, distance and speed. If it’s far enough away & small enough, we could try to change its path by flinging stuff by really close.

    If you want to feel deeply disturbed today. It’s a powerful short story.

      Woof. That was not the read I was expecting today. Shows just how fragile we all really are. My daughter just got a very tight bear hug. Thanks for sharing.

    That’s so fucking terrifying. What a bizzar was to go. My SciFi riddled brain wants to perceive it as a potential dark forest reaction, a non zero probability at least.

    This is why you should put a leash on your black hole

    Reminds me of this talk about black holes I saw recently… And an odd theory that our perceived universe might be located inside one already.

    Neat to think about, the idea that these things might be a means of travel between other universes, but you can’t know for sure and couldn’t tell anybody after the trip.
