    I took a physics course at a community college over 20 years ago and one of the things that stood out to me was the professor telling us not to overthink or assign too much romanticism to the idea of black holes.

    His message was basically “it just means the escape velocity is greater than the speed of light… if you plug the size and mass of the universe into the escape velocity formula, the result you get back is greater than the speed of light, so our entire universe is a black hole.”

    If this was being discussed at a community college decades ago then I think the new discoveries aren’t as revelatory as they would at first appear to the general public.

        On the contrary; while I have heard the explanation that the commenter you replied to has said I have also heard a slightly different theory:

        Our universe is the 3 dimensional event horizon of a 4th dimensional black hole. By extension we may find that black holes in our universe have similar funky 2 dimensional areas at their even horizons.

        I am sure clickbait articles are part of it but there also seems to be several actual theories surrounding the idea of the nature of our universe relating to black holes.

    This is a postulation not a discovery.

    Someone did a weird math thingy that gave a word result and this was how they tried to explain it. There’s been zero confirmation this is actually the case. Just like they can’t decide if dark energy/matter is a thing.

      We have a theory for expansion of the universe. It is called “the big bang theory”.

      However according to the math our universe should slow down expanding, but we can observe it is speeding up. Solution? Dark Energy.

      There are models that try to simulate the orbits and shit of things we can see. Now those models aren’t working however… Solution? Dark matter.

      This is very run down concept of what dark matter and energy is. Basically shit we need for the math to work out to the observation we make.

      However I don’t think we are inside a black hole. This would mean that instead of mostly nothing our universe would be cramped with matter…

        If you take all the mass in our universe and run it through the Schwarzschild equation, you get a black hole with about the same radius as our observable universe.

        Things don’t need to be tightly packed to be a black hole, there just needs to be enough stuff in an area.

        There’s also been some major leaps in dark matter physics in the last few years. Revisiting primordial black holes using lasers and microlensing might actually be able to get supporting evidence here before long if the hypothesis holds.

        PBS Space Time has a good video breaking this possibility and methodology down.

        There’s also cyclic conformal universe theory, put forth by Penrose.

        Where once you have an empty enough space… its mathematically indistinguishable from a singularity.

        So, if its true, then yeah, we could be inside of a blackhole/singularity.

        Look up vacuum decay. It’s theoretically a thing that can rewrite spacetime at a lower energy level, and would expand out from a point in a bubble. The expanding bubble would erase and rewrite everything it touched into the lower energy level.

    Ok I've been meaning to ask this in the Space community or the NoStupidQuestions community. I've seen this news circling around the past 2 weeks and have been watching videos of people talking about it.

    Someone correct me if I'm wrong but I think the gist is that astronomers discovered with the JWST that some galaxies at the end of the observable universe appear to be younger than they are supposed to be. So it kinda blows a hole in the big bang expansion where objects farther away should be older. And that somehow ties in with the theory that our universe is inside a blackhole.

    It's fascinating but I don't know what to do with that information other than just be fascinated. I think it was Neil deGrasse Tyson who said "what does it matter to us? nothing", because us being in a blackhole doesn't change anything in the scale of our universe.

    source
    • MotoAsh@lemmy.world ⁨2⁩ ⁨weeks⁩ ago

      From what I’ve seen, it’s not that they’re “young” galaxies, but that they shouldn’t have had enough time to develop if the universe were truly so crazily homogenous from the big bang. It doesn’t necessarily disprove the big bang, just means the universe might not be as “smooth” as previous assumptions.

      Another big part of it is that if the big bang happened evenly then galaxies and other objects should be spinning in random directions. So far that's not what's been observed. There seems to be a preferred direction everything spins in.

        I’m sorry but i think that’s just not true?

        Inside the solar system, yes, planets more or less spin around the same axis than the whole solar system does.

        But the axis of the solar system and of the whole milky way are like 63° towards each other. Source So, not the same direction at all.

      We also have to remember that we can only see a bounded sphere of the universe from our frame of reference.

      If we were to move our observation points to elsewhere in the universe, we’ll be able to see more of the universe and challenge our current theories.

      The JSWT sees only what it can, and our theories about the universe can only extend as far as that evidence. Those galaxies might appear to be younger, but the science is never finished!

        Nah, that would require spacetime to curve a lot more than it does. It’d also have to curve in the other direction (local spacetime is hyperbolic, “local” as in basically all of the observable universe). Calculations show the universe must be several times larger than the observable universe in order to match even Hubble observations, let alone JWST observations.

      The Hubble radius of the universe is also equal to its Schwarzschild radius, which is a requirement for any “we’re inside a black hole” theory.

      source
      • woodenghost@hexbear.net ⁨2⁩ ⁨weeks⁩ ago

        That’s not an empirical observation nor a new discovery though. It just an analogy that leans on the definition of Schwarzschild Radius. No one is seriously implying, that we’re somehow trapped in a black hole.

        In fact, the analogy only holds, if the Hubble parameter is constant and this new result, if it holds up, would still indicate, that it is not constant. As was expected by the standard model of cosmology. If the Hubble constant is decreasing, and consensus is that it does, than the Hubble radius is also different from an event horizon in the following way: light reaching us from more than 5 billion years ago comes from regions that have always been receding from us at speeds faster than light.

    NOT “discovered inside black hole”, just gained further theoretical evidence for the Earth being in a less dense area of the universe.
