    I’m completely a layman, so don’t take my word as fact. But currently there’s a trend in thinking that because more than half of the galaxies they’ve been measured all rotate the same direction (as opposed to all random directions that a uniform static bang should result in) then the universe started out spinning in that direction.

    What starts from a very small condensed state, and expands rapidly while spinning in one direction? Black holes.

    Black holes also go through a life cycle that’s pretty close to what we expect or universe to go through.

    It’s a new thought, I’m not even sure how much evidence there is past the galaxyspinning evidence. But it’s interesting and has scientists thinking.

    It also takes care of any “multiverse” questions, since black holes are already in a universe. Some of the holes could be pocket universes, and we could be in one, with black hole pocket universes of our own.

      The observable universe is also way denser than a black hole of equivelent radius (black holes get lower in density the bigger they get) so one way or another we are in a black hole in the sense that somewhere out there is an event horizon through which you can never leave, just not in the traditional understanding which only really applies to ‘small’ (every single other) black holes.

      I’m not even sure how much evidence there is past the galaxyspinning evidence

      There was another article posted recently I can’t find now, that talked about the discrepancy between the age of the universe based on the Hubble constant, and what’s observed of the CMB, or something like that. Apparently that discrepancy can be resolved if the universe itself is rotating.

      Really hoping someone can track it down and post up a link, I’m probably making hash of the actual article…

      I’m a layman, too, so take everything with a grain of salt.

      As for evidence, if I both understood and remember correctly, the maximum distance we can actually see something (Hubble radius) just happens to align quite nicely with the Schwarzschild radius, a parameter based on the mass of a black hole, which correlates to its radius. They have to be identical for this theory to be true. Them almost being so could be a coincidence, though.

      In addition, from our perspective, there’s no real difference between an expanding universe and one with shrinking particles. If the planck length actually shrinks, to us, it will seem like everything else will move away. Within the last 100 years, multiple people created some models for that, proving how it could work while leaving physics as we observe them intact.

      A proof could be found by observing a white hole, the opposite of a black hole. A space you cannot possibly enter, ejecting energy. Think of it as the stuff entering the black hole from the outside, as oberserved from the inside. They are just a theory for now.

      Once again, I’ve got not actual clue and you might want to dive into that rabbit hole yourself. It’s fun in here.

        Now that you mention it, i forgot about the radius possibility. Thanks for the follow-up!

      Would our universe need to behave like anything inside our universe though? It could be a rotating expanding universe without being a black hole

        The goal here is to make probable inferences, not to avoid being wrong at any cost. There’s always more possibilities, but we should try to eliminate the likely-seeming ones before chasing down less-likely ones. Know what I mean?

        The possibilities are as vast as our ignorance: greater than we have the means to measure by some indescribably large margin.

      Ive never heard of black holes suddenly expanding. Everything ive read js that they just very, very, very slowly dissipate through Schwartzchild radiation.

          What’s the “they” that you mean? The event horizon, the transition point where light can’t escape?

          That doesn’t sound like what they were saying. The actual “hole” supposedly remains infinitely small. And the event horizon radius would expand at a pretty slow rate as matter fell into the black hole. Exponentially smaller as it gains mass.

          So I’m still trying to understand in what case a black hole ever “expands rapidly”.

            Dude, everyone here has said they’re not experts. Idk what you’re expecting us to say.

              Dude, I’m expecting the most basic explanation of what someone meant by something they said. Claiming not to be an expert isn’t a good response when someone asks wtf you meant

              You said

              What starts from a very small condensed state, and expands rapidly while spinning in one direction? Black holes.

              I’m asking where you got that from, since it’s the opposite of anything ive ever heard about black holes and what almost anyone thinks about black holes.

      Smarty pants. I don’t find any issues with your thought prices, process but I’m a layperson.
