    That begs the question: If we are in a black hole and we have observed black holes within our frame of reference. How dense can matter get? It's like the square of a square. If we're in a black hole and we have local black holes, do those black holes also contain black holes? Where does that end and what does that entail when we extrapolate out the end of our universe?

      Just like how living beings reproduce, i think the big bang was just a white hole at the other end of a black hole giving birth to a new universe... and that black holes in our current universe will in turn give birth to their own respective universes. Its like a cosmic breeding ground on an incomprehensibly massive scale... and that is cool AF.

      It makes sense, which in no way is enough proof to say for certain, but it's still fascinating. Physicists hypothesized that to travel to another universe, you would need to create a hole in spacetime. How do you do that? With extreme pressure focused on a single point; like a blackhole with monumental gravitational pressure bearing down on a singularity. The singularity being defined as "a theoretical condition in which gravity is predicted to be so intense that spacetime itself would break down catastrophically" really makes you wonder if spacetime breaking down at the singularity of a blackhole creates the conditions necessary to leave our universe for another!

    As someone who deeply admires you and values critical thinking and scientific reasoning-within my humble capacities-I found this episode both fascinating and humbling. The notion of a cosmic horizon beyond which no information has yet reached us is a powerful reminder that our understanding of the universe is inherently limited.
    Even with all our telescopes, equations, and expanding models, there are entire regions of reality we simply cannot access-perhaps ever. And yet, science progresses not by pretending to know everything, but by honestly acknowledging what we don’t know. That, to me, is what makes science beautiful: its commitment to evidence, its tolerance for uncertainty, and its refusal to overpromise.

      Yes, our Universe is definitely rotating, but it's not a "black hole"...
      Everything, from the only 2 existing fundamental particles of opposite charge (the electron & positron) to the whole finite Universe, is pure rotational energy with eternally conserved angular momentum, in an infinite chain of dynamic cycles of expansion and contraction with no beginning and no end.
      The Standard Model of Particle Physics (a cool math game of illusory statistics & probabilities) with all of its fantastical Quantum Zhait soup, is wrong. Imho, Ernest Sternglass discovered the closest thing we have to a ToE, and XiangHe masterfully interpreted it in the most simple, sound, and logically coherent way I've encountered.

      @@v1kt0u5 Cosmologists have looked for signs of large-scale rotation of the universe (a global "spin" or preferred direction) and found no compelling evidence. The cosmic microwave background radiation (CMB) is extremely uniform and isotropic, which strongly suggests that the universe is not rotating as a whole.
      A rotating universe would violate cosmological principles (homogeneity and isotropy) and could have observable consequences, such as anisotropies in the CMB, which we don’t see.
      Yes, angular momentum is conserved in physics. However, not everything is “pure rotational energy.” Particles and systems have various forms of energy - kinetic, potential, rest mass energy, thermal, electromagnetic, etc.
      Spin is a property of particles (like electrons), but calling them “pure rotational energy” misrepresents the quantum nature of spin - it's not classical rotation, but a fundamental quantum number.

      Would make perfect sense. The blackhole sucks in material into a singularity. Once it reaches a critical size the material explodes in a big bang forming the new universe. As the blackhole increases in size it pulls in exponentiallh more amounts from outside the event horizon which drives the accelerating expansion of the universe. This would explain why we can never see the edge of the universe as it expands close to the speed of light and we were formed billions of years after the initial big bang. It would also make sense when two black holes colliding create insane energy levels seen in pulsars as its effectively two old universes annihilating eachother.
      An infinite number of blackhole causing an infinite number of big bangs and creating an infinite number of universes. An ever perpetuating cycle.

      L= r x mv, where r and v are inversely proportional, so if r decreases, then v increases, which is the result we're expecting.

      If it is true, then the black hole we are inside of, need not be 'universe size' at all.
      Once it's formed, the universal constants (of our universe) will automatically fine-tune themselves to make 'sense' of our universe.
      So even if our parent black hole is the size of a typical supermassive black-hole.. our universal constants such as speed of light, time, mass, energy, etc will make sure that we can never reach its event horizon.
      So, in essence, from the perspective of our parent universe, we may be very tiny. And our speed of light may be barely equal to walking speed.. None of that will matter as both the universes can never interact.
      It's also possible that the supermassive black-holes of our universe may be housing similar parallel universes, with we having no means to interact with them.
      The event which we refer to as 'big bang' may be just the event that gave birth to our parent black hole.

As we know, our universe also contains black holes.

      and unbiased. Think of it like a jar holding just two colors of M&Ms, and you want to estimate the true frequency of each. whether it’s ten thousand or ten billion m&ms in the jar,a random and unbiased sample of 300 will give you similar amounts of statical power.

    Our universe being a giant blackhole makes sense honestly. It would explain the universe constantly expanding (as our blackhole devours everything in its path) ultimately expanding our universe. You have to travel faster than the speed of light to leave our universe. A blackhole forming would begin our known existence. I think the universe is all based on blackholes and what they destroy and create at the same time. Its a neverending cycle, blackholes inside of blackholes. When something dies, new life begins.

      @@KodomaNot an astronomer, but I think this is addressed in the video 01:45. The density of a black hole is dependent on its size. As black holes get really large (ie universe-sized) their internal density stops being crushingly high, and instead is something like what we have in our observable universe. There's still an event horizon (a perimeter that can't be traversed), but the inside of a universe-sized black hole would be no more crushed than our universe is. At least that's what the math says. I think.

    I thought the assumption was that if you fell into a black hole, you would be ripped apart. That would imply that anything in the black hole is no longer in the form it was in prior to crossing the event horizon. So if we are in a black hole, that implies that prior to crossing the event horizon, "something was ripped apart", and the "pieces" of that thing eventually coalesced into whatever makes up our universe, perhaps billions of years after crossing that event horizon. And since we've observed black holes, that further implies that there are black holes inside of black holes since we wouldn't be able to see black holes that are outside the event horizon if we are inside. Oh man, my head hurts.

      Or conversely, As the Parent Black Hole's event horizon shrinks due to Hawking Radiation, Inversely the Spacetime "inside" expands, since the mathmatical properties of spacetime inside a black hole's Event Horizon are inversed, 3D Space becomes 3D Time and 1D Time becomes 1D Space, and a hypothetical White Hole made from the formation of this black hole would have it's Time run in reverse to the PBH (Parent Black Hole).
      I Hypothesize that our universe Is that hypothetical White Hole
      From this, A correlation can be made between the Exponential increase in Hawking radiation as the Horizon's Surface Area (it's Space) Decreases Vs The Exponential Accelleration of SpaceTime as Time Increases.
      Though your idea about Matter being sucked into the Parent Black Hole influencing the universe inside also has weight in this hypothetical, as there was a period in our universe's timeline where there was a massive Deaccelleration of Spacetime (relative to the Inflation Era) just after the first fundamental particles started forming, (currently explained by Gravity), however this could be also explained as the increase in surface area of the event horison increasing as the rate at which it gobbles up all of the matter available to it outpaces the rate at which Hawking Radiation can evaporate that energy away, and then by the time our universe is 8.8 Billion years old, The PBH can no longer eat more than it evaporates, and thus the age of Accelleration begins!
      One Major contender for a black hole that fits the description of something that Feasts for so long is actually the black holes that become our Super Massive Black Holes at the centre of our galaxies, As they have been able to feed for the longest.
      The Hubble Tension is a sore spot for this hypothetical, because we're still unsure Why the CMB is at odds with our current measurements, However If future scientists discover that the Cosmological Constant has increased from what we calculate now, it could give us insight as to what mechanics are at play with the expansion of the universe, and possibly confirm hypotheses we are commenting on this very video!

    4:40 Hi Niel! Actually, the angular velocity does not scale as inversely proportional to the radius, but rather to its square. You mention mv^2/r, but that is the centripetal force which isn't the relevant quantity here.
    The angular momentum for a point mass is mvr, which is mωr^2 where ω=dθ/dt. Therefore, conservation of angular momentum increases the rotational speed by the inverse square of the radius, i.e. 1/2 the radius rotates 4 times as fast.

    My favorite tidbit about black hole cosmology - is that white holes do exist, but they are temporal to those inside a black hole: they're an event in the past that exerts so much temporal force that it's nearly impossible to travel towards it (as it would require traveling backwards in time)

      not really.
      for all the blackholes in our universe, the universe inside those blackholes are one and the same universe, not separate universes.
      why do you think that is true?

      If this is true, then what's inside the black hole in the black hole in the black hole we are living in?
      And what's outside the black hole of the black hole of our black hole universe? That make the scale of the universe even more terrifying.

    This title/theory broke my brain for a minute before clicking on the video where I was imagining other universes inside known black holes in our own observable universe. The possibilities are simultaneously mind-bendingly awesome and kind of depressing to think about. What if intelligent life does exist in other worlds inside other black holes, but we're destined to never meet or interact due to how the universe works? Also, what does this theory mean for dark matter? Could be a key to figuring that out! Very interesting stuff.

    The best thing about science, is you can ask some of the most obscene thoughts, yet still take what you can observe at full face value, while HOPEFULLY learning from it somehow, if not, adjust a minor detail and try again.

    I've suspected for quite awhile that we may be inside an evaporating black hole, with the big bang being the singularity falling apart and spreading outward.

    So couldn't that mean the roughly 40 quintillion black hole in the observable universe are all their own universes themselves that were born out of our own black hole universe? That could mean we've got a super web of universes where each black hole could have their own 40 quintillion black holes at their own scale, all with universes of their own? Infinity goes in both directions, from the infinitely large to the infinitely small, so there's some room to work with.

      It sure seems if this were the case the main material used to make a universe would have to be the imploded then regurgitated remains of a super massive star. (That is what makes black holes in this universe) So would there be enough of anything to make a whole universe off of one star plus anything it could find to eat close to it? It seems these would be countless little bitty new universes if that is what's happening. Whatever we would be made from would be unbelievably huge by human scales.

      our universe has quintillions of blackholes, but all those universes inside them are one and the same universe.
      why?
      when two blackholes merge, the inside universe experience no change.
      why?
