The theory that each black-hole contains its own universe, such as ours, has always fascinated me. However given our universe contains millions of black-holes itself I'm not sure how to reconcile this potentially endless 'nesting' of black-holes within black-holes within black-holes.

[@ThisIsTheIkeMaster]

I believe black holes pair with white holes in gravitationally interactive parallel universe with differing arrows of time and that eventually all blackholes will combine and pair with a whitehole in a temporally inverse universe. In the meantime, I reckon blackholes leak into universes with adjacent arrows of time. The inverse universe ends the same way, causing our big bang. Matter in the adjacent universes could cause our dark matter and matter in the inverse universe would be our dark energy.

[@Onoesmahpie]

Perhaps the conditions of a black hole allow for new types of quark matter to exist as degrees of freedom, i.e., a "second physics" nested within ours, and similarly our universe is in a black hole outside of which our fundamental particles are locked within others and are not degrees of freedom

[@Thetruthiscosmic]

I'll never forget the moment when, while doing research of my own about black and white holes and learning about some of the topics you covered in the video, I had the realization that the big bang itself was a white hole. And also that it must have come from a black hole, which could mean that not only are black holes possible universe-creators but also that even though our universe will some day die and fade away in darkness, black holes that exist today could possibly be the new source of new universes. These are scales beyond our comprehension or imagination, but I love that there are so many of us interested in these topics. I truly believe the Earth would be a better place if every human understood the basics of these topics or at least were interested in learning and understanding them.

[@PW-zs2yx]

Yes how interesting so the massive black hole at the center of our own galaxy could one day become a new universe

[@Butzacooky]

I literally had the same realization! That dawning feeling is crazy! It really made me just absolutely geek out and truly learn to love the fundamental physics of our reality. It’s just so exciting to consider this dimensionality we cannot yet describe. I’m jealous of the future physics that humanity will uncover. Truly. There is one truth that our generation has had that I really believe wasn’t there with TV, and that is specifically community-generated video content- aka KZbin. There is absolutely no way I would have learned such a strong understanding of the physical nature of light, space, mass, exponential, sines, etc. I wish this was emphasized more! No high school or undergraduate college education will go to EXPLAIN the reason why we do the problem sets we get.. It’s so crucial for progress.

[@LesterWayneDobos]

Yes I agree. It is a relief being able to at least comprehend a cosmology that would make sense other than to revert to the understandings of primitive religion. The Big Bang resembles that of a white hole and it is not a stretch of the imagination (no pun intended) to visualize where all the ultra compression goes to. If black holes deep within are out of our space time the only next plausible idea to consider is that they are in another space time. Quite a beautiful idea that would seem to make sense.

Like how volcanic vents at the bottom of the ocean are the best places to find life at, despite the fatal pressure and heat. It's so beautiful. I feel small, but in a good way.

The idea that the Big Bang is actually a white hole is extremely interesting. There are a lot of similarities between what we understand of the Big Bang and what we theorize a white hole would be. If it’s true then every time we spot a black hole we know that a new universe is being created, yet at the same time we also know that we’ll never be able to see it. Really interesting idea. If all of this turns out to be true, it would give us such a different perspective of the universe and how it works.

17:54 - genuine question: if space is indeed as vast as it is purported to be, is it all that surprising that to track something such as a White Hole we'd need to look beyond our relatively small corner of space? Part of why I am so excited for the JWST, because we'll be able to see so much further. But everytime someone says "we haven't observed this" my first thought it always "well space is so huge aren't the odds somewhat against us in observing rare things?" We have to get lucky, and just because we haven't seen a phenomenon yet doesn't mean that it's not out there. It just means we haven't yet spotted such a phenomenon, whether as a consequence of our technological capabilities or the fact that given how vast the universe is we just haven't observed enough of it in the required detail to catch such phenomenons. I love this subject immensely, but it always seems like people are so ready to throw something away before *any* evidence is truly gathered. When it comes to space, I feel as though pretty much everything ought to remain on the table considering a) how big the universe truly is, and b) how recently we have developed the technologies capable of going further in depth. I realize you're presenting the arguments and not siding with one or the other, so this is in no way directed at you or the content you produce (which I love immensely btw), but this seems like something broadly that as an outsider I feel isn't talked about at least with the frequency and vigor that it hits the mainstream. When it comes to the shear vastness of space, it seems like nothing should be off the proverbial table when it comes to theories.

[@ladyajninja23]

I'm absolutely never disappointed in each new upload. Impressive content put together and told in an impressive way. My life has just been flipped upside down with a very difficult and life threatening pregnancy for myself and my baby, and as a single mother now to a now finally perfectly healthy baby girl, I loved to unwind and watch these videos pre baby, they helped me thru some of my toughest times, and now even more that I have her & when I DO actually have the time, I love to spend it watching these videos! Plus the videos also help her to fall asleep at times and educational for her. What better could I ask for as a mama in serious need of me time and down time, these videos provide for the both of us. Such a treat and can be a very rare thing to find for such a situation / and situations in life. Truly appreciate this content and wanted to share how awesome it is for my little one and I in our new journey in life. Means a lot! Just as the information shared means so much ! Thank you sea!!!

I bet we have confused a lot of black holes with white holes because they would look so similar from far away,

[@cosicave5179]

Many years ago, whilst doing my own original research into black holes, I came to realise that our observable universe - which has a boundary beyond which we can never see - is analogous to being in the INSIDE of a (universe sized) black hole, which according to our most recent interpretations of ever more accurate observations, appears to be expanding… Also, I'd like to congratulate 'SEA' for what is once again, a very, VERY good video. Topics are well presented and clearly narrated.

[@hihtitmamnan]

“is analogous to being in the INSIDE of a (universe sized) black hole” - We have timelike time and spacelike space in our universe. This strongly suggests we aren't :)

In black holes new universes are being born..then the black holes in those universes will take in matter and the process starts again..and again..and again.. , then again the theory could be completely wrong, but its a good one

[@berjaboy]

I think that what's inside a black hole is what you'd fine beyond the edge of the universe. What was "before" the universe, or what is the universe expanding into? A place where all our physics breakdown. Where all our math breakdowns. A place disconnected from our universe. Something very similar to what we believe is in a black hole.

[@jamesdavison6290]

One thing always bothers me about spacetime. Since objects only fall downward, the black hole forms a hyperbolic torus going only in one direction. If space were positively curved into a hypersphere, then the black holes could be all connecting at the center, or else all projecting outward like spikes. If space had a negatively curved saddle shape then the black holes might cross along certain hyperbolic lines, but would likely never intersect, depending upon their location. But either way, spacetime is always deflected by acceleration or gravity in a single direction. Of course, both are defined by time, so this suggests the arrow of time is indeed imbedded in spacetime. Is it possible that negative mass with negative properties of acceleration and spacetime deflection in an opposite direction can co-exist in our universe? Thanks to anybody who can explain this.

[@mannys9130]

I believe in the Ekpyrotic Model of the universe, and I believe in quantum mechanics. We have observed QM in action right before our very eyes. Example? The device with which you're reading this comment is relying on NAND flash non-volatile memory to do so. A floating gate transistor depends on electrons quantum tunneling across the gate gap into the chunk of insulator within. You can either "inject" high voltage electrons into the insulator (which damages it and is undesirable) or you can use juuuuuusstttt enough voltage potential to allow the electrons' quantum wave function to have a large enough probability of the electron suddenly existing and reappearing inside the insulator instead. Classical physics of any kind simply CANNOT explain that. It is literally like watching a person walk through walls and be totally fine. So...I put more faith in QM, M theory, and Loop Quantum Gravity than I do in other models. The Big Bang was actually 2 undulating membranes in a 5D bulk colliding and populating with matter as a result of that collision's kinetic energy. I'm undecided whether the branes create one universe at a time, or whether the branes are infinite and each local undulation that causes a collision creates a local multiverse in that place. It's possible that the Hubble Constant is a result of distance from our twin brane, and eventually the collision recoil will stop and the expansion of spacetime will reach its maximum rate before it begins to fall back down again as the branes fall back toward each other for another collision. By the time they touch, the heat death of the current universe will have already occurred and everything will be at equilibrium. I think it's possible that our brane received matter and the twin received antimatter, and black holes are actually a 1-way connection to the twin brane whereupon matter is annihilated upon contact with the antimatter. The rules of physics may be flipped in the twin brane where time flows backward and mass repels. Or, black holes may be quantum objects where matter is safely stored inside on a secondary "inner" event horizon. This would make sense as well, given that at the "Page Time" the entropy of a black hole reaches a maximum and begins decreasing as the information within is slowly given back to the universe. I just don't believe that a black hole is an infinite point-like gravity well which has an infinitely dense singularity inside of it which destroys information and makes the matter completely irretrievable forever. 🤷🏼‍♂️

Short answer no...long answer the amount of energy you would need to maintain systems (ship, shield, connection, etc...) It just isn't feasible at current energy technology. However....given a better understanding of our universe and hydrogen and helium fusion technology (our sun essentially), maybe. Not to mention some serious upgrades to current propulsion technology.

[@offlinegamer6756]

thank's bud ! the only reasonable comment in this sea of dreamers and science fiction lovers , they keep calling it a hole when in reality it's a rotating spherical object , with two poles and an accretion disk at it's equatorial center which contain it event horizon and it has an infinite gravitational force , so huge that even photons can't escape it attraction , and in it center you'll find a still unknown state of matter called singularity ....so no hole , i'll do prefer Sphere of infinite gravitational force or SIGF !

[@Filboid2000]

I see one problem with the idea that black holes are connected to white holes that create other universes, and that problem is of diminishing returns. If the big bang was a white hole "burping", it had to accumulate an extraordinary amount matter to create our universe. The black holes that are observed today could not have accumulated anywhere near enough matter to create universes of their own. However, if through the passage of time everything within our universe was to be gobbled up by black holes and they, in turn, gobbled each other up until there was one incredibly huge super-duper black hole, then it the amount of matter would reach a tipping point to generate a super-duper universe-creating "burp".

[@mariolawrence897]

You managed to talk about black holes, without making them seem too terrifying. Great video!

[@Thetruthiscosmic]

Fun fact, if you were to stand/float on the very edge of the event horizon, light/photons there are traveling so fast and orbitting the black hole at such speeds that you would see the back of your body in front of you. Like a mirror of sorts, only it's not a reflection, it's light traveling so fast that your body's image travels along with it.

[@nct948]

I thought light travels at a constant speed. A black hole would not cause light to move faster than itself.

What if the matter inside a black hole is simply compacted to a point just beyond the event horizon? How can we presume that a proportionally small singularity point lies within an empty outer area? I think we may be overthinking black holes. Not being able to see into it doesn't mean nothing is there.

[@sjzara]

The singularities aren’t at infinite times. On these diagrams the singularities aren’t straight lines but curves. Future singularities can be reached in finite time. Also, the existence of wormholes aren’t anything to do with String Theory - they are a feature of quantum gravity theories in general. The Big Bang was nothing like a white hole. There was no external space, and so energy was not pushed out, as there was no “out”. Black hole cosmology is not connected to wormholes. The “bounce” is not a wormhole solution, but a feature of quantum gravity. The end of a stellar black hole is not a white hole, but an explosion of around 5 million megatons! Powerful, but hardly cosmos-lighting. Getting these things right involves quite a lot of research. Your graphics are beautiful. Why not give it the content it richly deserved?

Nice video. I don't see a reason to suspect, that supermassive black holes might eventually burst out matter somewhere else, because black holes as we know them already have many infinite characteristics, so no reason why they couldn't pack on unlimited mass. Also, it seems to me, that white holes do exist, but they're simply the black holes themselves, just in the opposite direction of time.

[@nancyhope2205]

I have trouble seeing this. First it isn’t a hole it is a dense spherical mass, second, how is there is 3 Dimensional geometry that supports the hypothesis?

[@magmax7141]

A black hole ISN'T a hole. It's a collapsed core of a stellar remnant. It's just an incredibly dense ball of iron with tremendous amounts of gravity in which even light cannot escape - which is why it looks black.

[@jeremyvill]

What makes you think its iron?

[@manofsteel8728]

did you even watch the video

[@luminous4565]

A black hole is the event horizon you are looking at. The point where light cannot escape. A black hole is not a solid object, if from what im implying is that you think it is a ball of iron. A ball of iron cannot have such properties of a black hole. It is true that it is created by one of most energetic events, but the thing is the iron core does not withstand the power of the matter and gravity in all directions surrounding it. It creates a infinitely dense point, or or becomes something very close, a neutron star. A black hole is not made of matter, it is an absence of everything. The singularity is the only object inside a black hole, if we can really call it that with how broken the laws of everything become inside a black hole. We call it a black hole because it looks like one on paper. Everything falls into it, like a hole in the ground. Black holes are not made of iron. The logic that it is a ball of iron, but no light can escape it, is false. The iron core and the rest of the collapsed star become victim to an environment that replicates the beginning of the universe at a point. The gravity of itself becomes infinitely strong, making the singularity an infinitely small point. This was probably unessecary to just saying its not a ball of iron, but I guess thats just my nerdy self coming out.
