Black holes keep ‘burping up’ stars they destroyed years earlier, and astronomers don’t know why::Years after ripping stars to shreds, 24 black holes suddenly flared up with radio waves in inexplicable ‘burping’ bouts. Half of all star-killing black holes may experience the same.

    No indication that any of the returning matter ever made it beyond the event horizon but how wild would it be if matter can come back from that somehow, would shatter current understand of the phenom.

      It would be amazing if that happened! We desperately need to be proven wrong somewhere if we want to develop a theory of quantum gravity.

        The Cat: So, what is it?

        Kryten: I’ve never seen one before - no one has - but I’m guessing it’s a white hole.

        Rimmer: A white hole?

        Kryten: Every action has an equal and opposite reaction. A black hole sucks time and matter out of the Universe; a white hole returns it.

        Lister: So, that thing’s spewing time…

        Lister: [donning his fur-lined hat] … back into the Universe?

        Kryten: Precisely. That’s why we’re experiencing these curious time phenomena on board.

        Kryten: Every action has an equal and opposite reaction. A black hole sucks time and matter out of the Universe; a white hole returns it.

        Lister: [minus the hat] So, that thing’s spewing time…

        Lister: [donning his fur-lined hat, again] … back into the Universe?

        Kryten: Precisely. That’s why we’re experiencing these curious time phenomena on board.

        Lister: What time phenomena?

        Kryten: Like just then, when time repeated itself.

        The Cat: So, what is it?

        [Kryten, Rimmer, and Lister stare at Cat]

        The Cat: Only joking.

        A white hole is a theorized antithesis to a black hole. While a black hole sucks matter in and destroys it, a white hole seemingly creates new matter and sprays it into the universe.

        Afaik, we haven’t actually observed one before. It’s just a mathematical theory. But black holes used to be nothing more than theory, too.

        Edit: I haven’t seen Red Dwarf in so long, I didn’t realize you were referencing it. 🤣

    Ok so black holes are just teleporters to other dimensions right?!

    What if we’re currently travelling through one right now and we forgot to turn the oven off

    I wonder if it could be caused by other celestial bodies captured in the black hole’s orbit. Some new mass approaches the accretion disk and the gravitational pull slingshots some of the disk’s matter out.

      For the forces required to “pull” the matter out, we would need another singularity, but even then, that wouldn’t show this.

    those are the bad stars that are not wanted for the next universe that starts at the end of the black hole. our sun is definitely getting burped up in the future. :D
