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.

    It sounds like the matter isn’t coming out of the black hole, but actually the accretion disc that is in the process of being sucked into the black hole so we aren’t breaking the event horizon threshold as title suggests

      It wouldn’t be pop-sci if it didn’t have a misleading clickbait title!

      This is my assumption. Clearly the accretion disk isn’t the point of no return, or maybe stuff on the inside = past point of no return, stuff on the outside can get flung off?

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

    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.

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

        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.

        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. 🤣

    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

    Everything is cyclical, Every action has an equal opposite reaction. Birth/Creation - Life/Consumption - Death/Collapse.

    Given what we know of black holes the most recent attribute to be learnt is that whatever is consumed by a black hole the information/data remains on the surface of the black hole. So does that mean when it burps out a star is it the reverse of the initial consumption of that star with the exact same information/data it initially had.

    Now apply the same logic to a theoretical white hole and we begin to see more potential for a theoretical worrm hole
