    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.

    NOT “discovered inside black hole”, just gained further theoretical evidence for the Earth being in a less dense area of the universe. There has been actual evidence of such for some time (at least a decade), but there is uncertainty at such large scales so it cannot be called conclusive based only on a couple types of observation that may have erroneous procedures.

      But then there’s the guy who added all the mass and energy of the observable universe, calculated its’ Schwarzschild Radius, and came up with 13.8 billion light years.

      There’s also how our observable universe’s Hubble Horizon acts like a black hole event horizon, the way in which even the speed of light is insufficient to escape beyond.

      A lot of the math inside a black hole is eerily similar to the math of our own horizon, as traced by the age of the universe plus the speed of light.

    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
    • Resonosity@lemmy.dbzer0.com ⁨2⁩ ⁨hours⁩ ago

      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!

      Probably goes without saying

      source
    • MotoAsh@lemmy.world ⁨6⁩ ⁨hours⁩ 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.

        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.

        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 ⁨4⁩ ⁨hours⁩ 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.

      I mean on top of answering fundamental questions about the nature if reality, proving that the universe is a black hole would necessarily invalidate almost every religion. That fact alone would upend society, and probably in a bad way.

      Also, if the universe is a black hole that means the universe is capable of reproduction. If the universe reproduces, there is likely no limit to the number of times it can do so. If an infinite number of universes spawn an infinite number of children, it basically establishes reincarnation as a fact of life.

      And that’s ignoring all the philosophical implications such a discovery would immediately raise.

        No way, at all, what so ever.

Don’t most religions focus more on some entity or entities they think made or govern the universe more than what physical processes are “used” to do that, or what the ultimate shape of the universe is? Even when a contradiction is found, it’s easy enough for a religion to just say “well, that was metaphorical”, or “just the limited understanding given by (insert deity here) to our ancestors” or something along those lines to make it fit.
