I've long been curious as to what passing through a black hole would actually entail. My current understanding is......if one were to enter feet first, the steeply rising gravitational differencial would tear one's legs off of their body...and probably tear the entire body asunder. This, of course would be extremely painful, but on the positive side, it wouldn't last long. BHE
@@blackholeentry3489 I think that’s correct of a ‘smaller’ black hole. But in the case of a supermassive black hole, where the distance between the singularity and the event horizon is vast, from what I understand it would be theoretically possible for a human to enter and not be spaghettified/survive.

I've listen/veiwed many physics lectures on youtube. Mr.James Beacham just gave one of the best I've heard. Especially the importance of us, the responsibility of us. THE DARE to Value the future of our species,and our place in it . A new way of being, one that's not just a mediocre existence. I hope for this future. THIS INCREDIBLE WORLD, THIS MAGNIFICENT UNIVERSE WE ARE BLESSED to be an observer and participant of. THANK YOU MR.JAMES BEACHAM FOR THIS LECTURE. 🙏🙏🙏👏👏👏❤️❤️❤️.
The lecture was very interesting and full of brilliant ideas, Delivery was powerful with enormous courage, passion and skill on display. Very much appreciated.
The brilliant ideas part of the lecture is fascinating...but his final, extremely wishful commentary smacks of a political/social leaning, that is going to turn a lot of people off....our problem now, as a species, is that very few of us have the intelligence to even contemplate such thoughts...on the scale of human evolution, it is clear, that we only recently came down from the trees.
What struck me is presenting the notion that the visible universe is just that, and there's stuff beyond that which we know must be there, and as it crosses over an event horizon and enters into our visible universe it expands our knowledge that much more and now becomes visible to us, but like a black hole we can never see beyond the event horizon. Just like being in a black hole. Absolutely mesmerizing. Bravo.
Thats also because light speed relative to us, and also because everything is moving away from everything. If I remembering correctly its about 100 stars per second disappering beyond our visable universe 24/7/365.25
This actually confused me because it's quite the opposite of what is happening; where everything red shifts and makes the observable universe smaller...instead you're saying we should be seeing more (already established) stars or galaxies shifting from infrared into visible light.
So glad I found this! This lecture is just what the doctor ordered for explaining the advanced theoretical concepts of what's occurring in astrophysics today in plain language. Thanks for posting!
The prospect of each Black Hole containing it's own Universe is something I've believed since high school. The way I saw it, Time, Energy and Matter get pulled in- but Time, Energy and Matter don't just disappear; they have to go somewhere, so the existence of multiple universes (and of White Holes) has been something I have suspected for the better part of 17/18 years. I'm feeling a mixture of vindication, that my theory is shared by minds in the scientific community, and regret that I was never good enough with mathematics to actually JOIN that community and contribute from within.
I watched this now for the second time, after a few months realizing how true this could be. I gotten very fond of the thought we are in one and hope to find more connections over time. It even gives me hope it´s solvable, it´s all very encouraging. Somehow i have a feeling we are not gonna need a collider to proof things. We speed things up in another and much smaller device. Thanks for the presentation, very well put.
Perhaps we sit on the eventhorizon of a huge one. Observable universe is a eventhorizon of a black hole If space can warp what is want. Time and light bend along with it, space appears straight...but it might be very warpy.
I think it could not be because the black hole is probably extremly hot due to pressure from matter, you know... So hot that quantum particles get deconstructed or something. The equation for compessing visible universe into a black hole prroducing a black hole such and such bigger than the observable universe is just weird and unexplained to me...like the observable universe would be already more compressed than a black hole ftw
@@kristjan304 Black hole can be defined as an object with escape velocity higher than speed of light. To use the equation for escape velocity calculation, with radius 50 billion Ly, our universe would have to have mass of at least 3*10^53 kg to have escape velocity higher than the speed of light (= be a black hole). We cannot really see the light leaving our universe so either this equation is some subtle way of nature that shows us that universe expands faster than speed of light AND nothing can leave it. Or, this whole equations does not work universally for very large object with very low density (but huge mass in total). Question is, can we even think about Universe itelf as 3D object and apply on it same equation that we apply to stars and planets. In the end, the density of the universe is like... super close to zero. When put together, the mass would be huge, but in any random space in universe, you could feel no effect of it. Funny part happens, if you think about the amount of mass as being constant. What will happen once universe expands so much it stops being a "black hole". Which should happen if the radius reaches over 160 bilion Ly (if the mass of universe is 10^54 Kg as in video). Btw. i hope my math is correct, take it with the grain of salt :D This whole looks like a semanthic to me about what is/is not a black hole, rather than real science :D
It could simply be that the calculation for the mass of our observable universe is grossly inflated or that the calculation simply don't work at such a grand scale
@@tomatodamashi I would really love to know how do they know the mass of our universe :D Lets sum it up: Universe has billions of galaxies, billions of stars. Different star have different mass so you cannot really say 1 star = 1 sun. And stars are the easiest part, because you can detect them easily. Star system has planets, planets have satelites. Universe is full of trash from nebulae, asteroirds, dust, very small and very invisible matter. Even vacuum, believe or not is full of particles that have mass. Sure, it is only few particles per 1 m^3 but if you consider the size of f.e. our solar system, you can easily get tons and tons of particles. You can find the amount of matter varying from 1^52 to 1^54 but still that is just the estimate. Anyway, problem propably lies outside of the weight of all matter. I would say that used equation is wrong and cannot be applied to huge object that have huge mass, but also super low density. I wonder if Schwarzschild radius was ever proven. I think it is just a theory with no real proof.
Mr. James Beacham is outstanding. In my whole lifetime, I can't get his one minute vocabulary!!! Are we seeing the past cosmos, mostly, including black holes?!!! Marvelous lecture.
@@1972martind28 well it’s an effective make believe. How do you know crossing an event horizon almost the size of the universe doesn’t mean entering another? Even if the math is bad it’s a valid guess.
@@thoticcusprime9309 The OP said: “This is quite possibly the best explanation I have ever come across.” Your reply, “nah.” How is anyone but the OP in a position to disagree with the OP’s personal opinion? Do you live in his/her head? Have access to OP’s personal experiences? 🙄🙄🙄
This is the easiest-to-understand description of black hole I have ever listened to... at the same time, I learned many new things around this topic... loved it
The way he explained crossing the event horizon, a terrifying point of no return, felt like me facing the consequences of procrastination. Ironically, I started watching this while procrastinating. But ended up galvanized and inspired by his vision of inching forward toward progress on a cosmic scale even though we'll never cross that horizon. It's about the daily millimeter forward, both for its own sake and for the infinitely larger long term goal of broader awareness, knowledge, and benefit to others beyond my current capacity to imagine.
It didn’t take a turn, he basically said if we don’t get away from where we are currently headed we will NEVER succeed in exploration of anything outside our world, solar system, or the universe. And he’s right, progress has slowed down due to the factors he talked about, and if we don’t leave those old ways behind we won’t get anywhere.
He said literal fascism... What did he mean by that? LOL If these clowns want to feel morally superior to everyone else, they need to act morally superior to everyone else. Not just virtue signal nonsense for one minute out of the day while the remaining 23 hours and 59 minutes per is devoted to their own egocentric pursuits...
Omg. James is such a good politician - selling black hole research to poor people by telling that would explain why there are many overly rich people. Especially when ( I think ) such research is mostly done using tax money. And as far as I know rich people knows very well how to avoid taxes - thus not really sponsoring this and other researches. One thing that came first into my mind when watching this was: what about redshift. Most of the astro videos tends to agree that many many galaxies will float away from our visible universe not float into visible universe. I. E. Visible universe is expanding not shrinking into. I understand that when we apply spagettifying concept on large scale from inside out we could see outer edges eacaping with speed more that speed of light, just because we are falling into ourselves (our black hole universe) with speed greater than speed of light. That would mean that somewhere in our universe is the center of black hole. It is most probably somewhere outside of vsiible bubble. But I must assune that it must be the place of most recursive black hole in our universe. What is the recusrsion limit? Another thing - how do you guys know that artificial collisions are 1:1 to collisions in outer edge of atmosphere but with smaller scale maybe superconducting magnet mambo jumbo adds some weird spin in dimension that we cannot observe directly but increases invisible mass and when this invisibille ( for us) mass collide - you actually get invisible ( for our instruments ) black hole. And then they merge together until one gets big enough to attract matter that is visible for both (sets of) dimensions. Also why would physics differ between outer universe and inner one? Only thing that should differ is perception of time? About black hole collisions detected by scientists recently. If black holes could contain smaller black holes. Without violent explosion. But two similary sized black holes creates explosion. That can be detected by shrinking space millions of light years away. What would it for us when our (black hole) universe collide with similar size (black hole) universe? Would we even feel that? C is maximal speed of everything so when such huge bubbles collide it still would take billions of years for them to be completely "informed" about the event. When thinking about it black hole event Horizon probably forms outside of both black hole galaxy bubbles even before to they merge. Fascinating. I was thinking it is possible we are living in black hole universe before. But it makes more sense now. Also avout rich people and black holes. Isnt it all about "that distribution rule" which is present everywhere. Sorry forgot how ot is called but if something can be in different sizes - then there will be much more small ones and less and less huge ones. If we apply that rule ( name is somewhere in standup maths videos) and insert currently assumed galaxy core black hole count then we could calculate number of small scale black holes and see how probable is to find one in our solar system outer edges.
As nicer bloke that he is, he works at CERN. 666(see their Logo) & It’s the one thing that I dread & he just admitted that they’re now attempting to make a Black Hole. Guess what Black Holes eat.”Oh yes it was light. Our SUN !!
So thankful for YT. I’ve watched so many documentaries, shows, lectures, talks, seminars and debates over the past 13 +/- years, i’m now actually able to, not only keep up with and understand but also predict the direction of these talks.

this was a very interesting presentation. So many questions that still have no answer . Dr. James is amazing. I'm just now getting into the science of our universe. Every video I watch and every book I read it leaves me wanting more and more every time!

Explained? The hilarious thing is that Einstein's space time doesn't explain anything. Instead of these things attract, we get this absolutely undefined "space" bends. What bends um.... What is this fabric of space? And then us being on a spherical planet, how do we feel acceleration outward from the center of a ball, while someone on the other side does the same? Ever accelerating expansion of the earth😂. Then we take that obviously flawed theory and extrapolated it to get stuff expanding faster than the speed of light even though the model starts with nothing can go faster than C. And we are left with this model not explaining the space time fabric that does all the heavy lifting of the model. It just does even though it's own parameters say it can't.
@@chrisoakey9841Einsteins field equations aren’t undefined, they are precise. You are rubbishing one of science’s best theories, simple because you don’t understand it. You have completely misunderstood both Special and General relativity
@@Amethyst_Friend the equations are not undefined, though the assumptions flawed like light doesn't slow. but the fabric of space is undefined. you see, the Michelson-Morley experiment, dismissed ether as the fabric. so what is this space thing? the fabric of space/time is claimed to be compressed. but what is this fabric made of? and what proves it exists at all? it's ability to deflect is the basis for time dilation. but what is it. not atoms, or quantum bits. we are just expected to move past this giant missing piece. it is up there with dark matter being everywhere and 20* more common than other matter, but we just can't find any of them. - perhaps i don't understand. because so far, the responses are that you can't question Einstein. but so far no one has been able to explain what space is. so if you can define what the fabric of space is made of, i'm all ears.
Amazing talk. Could those giant cosmic voids be one part of what happens when a universe like ours is born from a black hole, as opposed to being a black hole where everything gets crushed into a singularity?
The thing that makes me feel extra insignificant right now is like...what if we're only on a very tiny, thin little circle inside the event horizon where our laws of physics remain stable? What if the event horizon is so huge that even a blip of falling into it is the entire lifespan of our stable-ish observable universe? I am high
Why do you need to feel 'insignificant'? You should feel Grand, to know that we exist in a world that is Grand and is trying to teach us amazing things about everything everyday. We should be proud to even exist and can explore and learn, and to enjoy the process of learning about the Universe and beyond.
I like this fractal approach to the explanation of reality. Because it's already what we observe in nature close to us. So why not at any scale, even the most enormous ones.
I love fractals, while not proof of any grand unifying concept, I still believe that they can provide some amazing food for thought. They are both remarkably concept and fundamentally natural.
@@bjchandler8937 The hall was never full. Go back to to the beginning of the video and check. Why would you misstate the easily verifiable just because you disagree with his societal views? Such an unscientific response to a scientist’s lecture.
His presentation skills are at a high school level. It's a broad overview of some existing models and theories, sprinkled with unverifiable conjecture and wishful thinking. The most interesting part of the entire speech was the testable portion at the beginning: If there is evidence for a dark body of substantial mass in the solar system, we could in fact try to intercept its estimated path and measure any gravitational deflection of the probe's course. I had hoped for more focus on this subject.
Being a lay person, I have no way of wrapping my head around some of these ideas or concepts. But I do have a question: What if we sent an object that was entangled with another object? Would the second entangled object react to what the one traveling into the black hole is experiencing?
If there is one thing that could untangle the two entangled objects it would be a black hole. Because an object that enters a black hole would undergo radical transformation as it's physical properties were seperated and stripped from its subatomic particles. It's where matter gets converted to energy so the connection between the two objects would become unstable and disrupted as one of the objects began to lose the unifying properties shared by the objects during entanglement
This is, in part, Lee Smolin's idea about universes reproducing through black holes. The "fecund universes" hypothesis might be untestable, but it explains so many phenomena at the same time. It is elegant, in other words, and parsimonious. For example, the same fundamental constants for life and for black holes are identical, so this would mean that cosmological evolution explains the anthropic coincidences perfectly (universes that are good at making black holes--i.e., good at reproducing--are also good at making life). And the math works (I'm told--I can't math to save my life).
According to general relativity, the immense gravitational pull of a black hole compresses matter and energy to an almost infinitely dense point, known as a singularity. While this implies that anything crossing the event horizon is essentially lost, some theoretical models suggest that black holes could be gateways to other regions of spacetime or even parallel universes. Another possibility is the existence of "white holes," hypothetical objects that expel matter instead of absorbing it, though no evidence has been found to confirm this. Advancements in quantum gravity and string theory might one day provide a clearer understanding of what happens beyond the event horizon, but for now, the other end of a black hole remains one of the great mysteries of modern physics.
@bradonhassell5567 you may think that, but about 50 percent of people disagree, which is why its bad form to get political in a lecture like this. It detracts from the very interesting and intriguing point of the lecture and alienates half the audience while adding essentially nothing of value to the lecture itself. Its very frustrating, even to many who agree with his political message, but especially to those thst dont.
Question for those with superior intelligence to me: Although its likely that entering a black hole can destroy all life, Is it possible that life can begin again over time, inside the black hole using all the material and matter that had been sucked into it previously?
THERE IS NO OTHER SIDE.. PERIOD. Anything going in is crushed to a point.. There is no coming out somewhere else. Because if that were the case then the black hole would not be as heavy. It would be like me putting items into a shopping bag and the shopping bag is the back hole. But if the bag has so bottom then the bag holds no weight, and if that were the case then the bag / black hole would not be bending space. Whatever goes in does not come out, it's crushed to a point smaller than an atom. And as for light being the fastest thing in the known universe, now we have a black hole acting like water or space going down a drain. A drain that even light cannot escape. This means that light is not the fastest thing in the universe, but rather space it's self is faster.
I always thought this… myself. I’m not a physicist. The Big Bang was a black hole… but the OTHER side of one. Infinite universes. All interwoven by black holes.
Exactly! There is no limit to what the mind can imagine, as long as one is still able to distinguish between what is real and what is imaginary. Voila! You have entered the creative world of art.
I always knew black holes were gatekeepers, but I had no idea they were so exclusive. It's like they're the bouncers of the universe, with a strict one-way policy. But I have to admit, the idea that our entire universe could be inside a black hole is mind-blowing. It's like the ultimate cosmic nesting doll.
I was thinking the universe was the output of a blackhole - what falls into it gets spat out the other side into a universe. I suppose this is essentially what he is saying.

@beacham here are a few hints: Assume existence is uniform and tends to infinity in both the small and the big. i.e there is not such thing as plank constant. It just goes smaller and smaller to infinity The universal law of big numbers The laws of thermodynamics Genrealization of infinity postulated by Richard Feynman. We only need to be certain that no matter what the limit is, but there is a limit to infinity Although we cannot understand infinity, we can understand its gradient. If you toss a coin an infinite number of times, the number of head and tails will be exact A photon will go through both slits only if it is made of infinitely small particles. Dark matter is probably this part below the plank constant that we never considered I don't know why, but relativity was required to understand why newton's law works. Now that we know, Newton's laws should be used Basically, the laws of thermodynamics and the laws of motion should be enough to model everything. Provided that the universe is a closed system. or at least for our perception
10:57 This is the 1st time I've heard someone talk about the flow up until now I've only heard about it bending space time so thanks. It makes way more sense now
It has always been a bit fraustrating to hear popular science hosts explain things in misleading ways for the sake of simple understandings. This guy did a great job, but I wish he would have shown better graphics to fully grasp the flow of space. I would recommend looking up the 3D model of gravitational space flow. You always see the stretch sheet with a heavy ball example but its so simplictic that it leaves a false impression of reality.
His presentation is also misleading: the "flow" inside a black hole is stretching the proper radial directions and squeezing the perpendicular ones, so the final singularity cannot be a "point at the center " as he claims... It is in the future for anything that falls inside. Black hole singularities are spacelike "hypersurfaces" when time comes to an end ( more accurately: spacetime comes to a self-destructing end), not "points"!

I think they're all wrong. Gravity is not a force that pulls you. I think gravity is a force that pushes. Gravity is a byproduct of the reaction of dark matter with the physical world. Newton's 3rd law say the forces between two masses are equal and opposite. However, when you fall towards the Earth the earth doesn't accelerate towards you at the same rate as you do toward the Earth. The answer would be the mass of the earth is so great and because it is so great it displaces more dark matter. The displacement of Dark Matter by physical matter causes gravity. The forces that accelerate you toward the larger body are a result of Dark Matter trying to reclaim physical space. The byproduct of this interaction between mass and dark matter provides the force of gravity. Which is different from the forces the objects have on each other based on the product of their masses and the inverse square of the distance between them. Collapsing a Mass of any size can trigger a dark matter response. That includes a collapsing star or a single atom. If you want faster-than-light travel that's the way it will be done. Collapsing matter around an object can give that object extraordinary burst of speed without generating the corresponding Heat or G-forces even when done in atmospheric conditions. Acceleration can create artificial gravity but it is the object's Mass displacement of dark matter that contributes to real-world gravity. These two forces of attraction can work together but dark matter flow is the dominating Force. The universe is swimming in a sea of dark matter that is constantly in movement. Because its density is not uniform that also provides an opportunity to open up wormholes. Like water dark matter flows towards areas that are less dense. That gravitational flow can be created any time a mass collapses instantaneously. This sets up a dark-matter Cascade. Matter isn't pulled into a black hole it is pushed into a black hole. Like water causing a dam to collapse. The dam collapse is not because of forces on the dry side of the dam pulling. The dam collapse is because of the forces on the wet side of the dam pushing through. Dark matter has the same characteristics. Dark Matter pushes everything into a black hole as it makes an exit through the black hole seeking an equilibrium. Like being pushed over Niagara Falls when you get too close to the Edge. The difference is the Dark Matter flow and the material it carries into the black hole with it can exit hundreds of billions of light years away adding to the expansion of the universe. I suggest you throw out the laws of physics as you know them. A perfect example of those laws being obsolete is the observation of our tic tac maneuvers that have been observed by military Pilots. Those objects effortlessly defy all the laws of known physics. Those objects have no need for aerodynamic flight surfaces, they don't produce a heat signature, and G-forces are irrelevant. I don't believe the world is ready for these advancements. The ability to use these concepts to create black holes, open up a wormhole, or greater than light speed travel could be devastating in the hands of primitive humans. However, it's the chance we have eventually got to take. Gravity is a force created by dark matter trying to reclaim physical space occupied by matter. A wormhole allows Dark Matter to flow out of this universe into another parallel universe or to a distant part of this universe where dark matter is deficient. A collapsing star or a subatomic particle causes a rapid decline in the amount of space that matter occupies. That sets up a "Cascade Effect" in the dark matter surrounding the star or particle. The density of matter has a direct proportional effect on dark matter that surrounds it. If all the known mathematical formulas for Gravity are combined in the symbol "N". We can then say that this concept of gravity would be represented by the formula Gravity = -1(N)
@@pentagrammaton6793 I think Dark Matter does exist. Not only that I believe dark matter and it's interaction with the physical universe is what causes gravity in the first place. It is my hypothesis that dark matter is the medium in which the physical world exists. It is the invisible ocean that the Universe swims in.
the whole idea of another universe being within a blackhole is something I've thought about many times, and I've heard pondered by others as well, but just a thought experiment. The fact that some mathematics points to that being a possibility is pretty nuts. But I have thought about how a black hole appears in an instant and how similar it is to a black hole. And I think I've even heard physicist's say that the same thing that kills black holes would kill the universe, which is essentially the cold. The very very very very cold, which causes everything to slowly lose energy.
But if the universe is expanding, doesn't that mean it is eating matter in the surrounding universe? And the event horizon would be glowing and the universe should be brilliant and hot. Except that it expands faster than the speed of light so the light never reaches us? That is my take away and the implication is that if it stops expanding, the universe becomes brilliant and prone to heat death
@@JohnDoe-qz1ql same thing in practice. Yes the expansion is occurring across the entire continium rather than just from the edges but a. I realise that and b. It has no bearing on what I said.
2 things definitely same about the black hole and the edge of the universe is that: Once you fall into a blackhole you can never come back; Once you go beyond the edge of the universe, you also can never come back because the edge of the universe is moving away faster than the speed of light and nothing beyond it can be seen, just like inside of a blackhole. Time ends at these 2 places.
As soon as you were born you passed the event horizon, there is no going back. And when you pass away you will experience singularity no space and time.
There's a major question that needs to be answered before we can make any headway with quantum gravity. If you have a quantum object, the position and momentum are uncertain. Is the gravitational field surrounding the object also uncertain? Penrose expressed that gravity might cause wavefunction collapse. If we can get a large enough object to behave as a quantum object, maybe we can detect some strangeness in the gravitational field. Or, maybe we can get some information from neutron star spectroscopy, looking for gravitational energy shifts.
Yes, that means the gravitational field is uncertain. Or in more modern lingo: the shape of spacetime itself is uncertain. That pretty much sums up why these two theories haven't been reconciled yet.
I loved this talk. And I don't want to sound ignorant, but I have a couple questions. 1. If black holes consume everything around them, making them bigger and bigger, consuming more and more, then how could one be the size of an apple just hanging out on the edge of our solar system? Wouldn't it be constantly growing bigger, eventually pulling our solar system into it? 2. Regarding getting sucked into a black hole and turning to spaghetti: Wouldn't that only be an illusion due to the observers position in space-time? Like, I would look around me and everything would stay normal, but to someone on the outside, I would LOOK like spaghetti or frozen forever on the edge only to an observer who's space-time was not being sucked into a black hole. 3. Regarding the possibility of being inside a black hole: absolutely. Because it is certainly possible, we are talking on these enormous scales of time. If black holes grow and grow and grow it is inevitable at some point eventually they would just get so huge and consume everything. But if this were possible and we are on the inside already, then we know that although they consume everything eventually in one universe, they will create another? Or maybe we pass thru unscathed and the noodly legs are again due to perception.....But the point is that I am most likely not understanding an aspect of black holes, or it is inevitable and when viewing at this huge perspective, it is not only inevitable, it has probably been happening gazillion into infinitude....which makes more sense than a big bang. a big bing gives us this like starting point out of a singularity all this crazy shit started to happen. Why tho? Why and doesn't it violate one of the most basic laws of physics that matter cannot be destroyed only changed into a different form? How could something happen from nothing, like the grand Nothingness?? In terms of the grand reality, doesnt it make more sense that there would be some kind of mechanism that could transform one reality or universe into another reality or universe over and over and over? Is ALWAYS a real possibility? Is it possible that this has ALWAYS been going on, there is no start or end, only from the perspective of an observer on either side? And what would that look like from our perspective after passing thru? I mean, we went into a black hole, so now we are here, when we look back to where we came from, what would that look like?? It might look like a start, because in a sense it is the start to this space-time reality,
I would love to hear this guy talk about the different types of black holes more, spinning vs static black holes, their charges, black holes made from light rather than matter, ring singularities vs point, ect. Would be facinating.
What he does is just tell stories and people like you believe it. Did you believe that you can make a black hole out of the Earth and it would be the size of a blueberry, you believe that right
@@blurta2011 Hypothetically it's perfectly possible to create a black hole out of the Earth, it's just you need god-like amounts of energy, and something like that isn't really going to happen to the Earth unless we were some kind of mega advanced type 3 civilisation. Even then would they want to do it? Probably not. But is it possible? 100% yes.
@@blurta2011Yes, I am studying physics in college. General Relativity is not something you take on faith, it has a rigorous backing in tensor calculus, and has computable predictions that have all been experimentally verified. This presenter only explained results, but the way these facts were ascertained were far more complex and take years of training to understand.
James has a knack for explaining physics perfectly, then adding a layer of comedy which had me smiling and I even lol'd and I don't lol that often. Especially the 'can we make a black hole out of...' and rush hour in London. An excellent presentation.

I recommend you read Autobiography of a Yogi by Paramahamsa Yogananda!!In his superconscious state, he saw the entire universe and "other" universes existing!
At first I thought "Duhhhh!", but then I listened further, and I love how this approach opens people's minds to more than what we see...and plays well into an expanding universe inside of a black hole in a bigger universe...
Absolutely brilliant. Goodness gracious, I didn't learn this much in all my school years than what I learned in this 1-hour. Ah ! Wish I could go back in time and do better at Physics and Math.
Your lecture very interesting. Sadly I’d have gone to the Albert Hall or the Royal Society! To watch live. And get to ask my question. But these events are never properly advertised. Great effort prof
If two particles become entangled, one gets gobbled by a black hole, will entanglement remain? Could this be used as a basis to communicate beyond the event horizon?
You can't use entanglement to communicate: you can't force your particle to resolve in a particular way - it's just random. You could use it to coordinate, but that's about it.
What happens to entangled electrons if we send one of them into event horizon and we change the spin of the other one outside the black hole. Does the spin of the "black hole electron" change? Does quantum entanglement work even in this scenario?
1) Once u forced-change to the spin of an entangled particle, the entanglement breaks down, and the other particle's spin will be random (50/50). So it's not possible. 2) You will also never know the state of the other entangled particle that went inside the blackhole, because any information about it can never be observed by those outside the black hole.
Not sure if your description of entanglement really nailed it, but that's not important. Why would entanglement work any differently just because one e- is now in the black hole? The only problem is we can't check it.
Amazing concepts and insights! Fantastic oration! Incredible presentation!! ...until the end. I find it unsettling that so many find the need to shoehorn in political messaging wherever they can. As the sciences are about unbiased facts and data, and not personal feelings and opinions; I feel the content of the conclusion was neither the right time, or place. Let's keep the realm of world politics and climate change to their own lectures. I respect all opinions, on all matters. However, the situation our world finds itself in, is far more complex than a few, well-worded metaphors. Regardless, excellent and very well done presentation! Bravo! You're still getting a thumbs up too. All the best. Let's build that accelerator!
I admire the conclusion for its scientific perspective on the essence of life and the intended societal structure by a divine being (he called it nature). It highlights how human greed and malevolence have corrupted these ideals, leading to societal issues like power imbalances, conflicts, and dishonesty. We're approaching a critical point akin to a figurative event horizon, symbolizing the ultimate consequences in the afterlife where accountability awaits. This concept aligns with the scientific discourse on the potential outcomes of human actions and their repercussions. Certainly! Our existence seems purposeful, void of randomness. We're here to prove our worthiness for heaven or hellfire in the afterlife.
Very inspirational and quite possible, I believe. We are currently very, very out of balance. Thank you for your time, effort and passion. Great rising to you!
I commented this above, tell me what you think. So, I didn't watch the Entire lecture, but I think this is the one I've seen before. He is the first person that I have heard explain that we live in a black hole, and not to toot my own horn but I came to this conclusion about 10 years ago. The way I realized this was something I thought he would have touched on, but he didn't. Anyhow, the evidence came from when scientists noticed all the galaxies are accelerating away from each other. So, consider this example. You drop a 1lb. iron ball into a well that is a vacuum and bottomless. It just keeps accelerating, then 1 second later you drop another. from the perspective of the person dropping the ball into the well you would see that the first ball is accelerating away from the second ball and therefore the second ball will never catch up to the first ball, but rather always be growing distant from the first ball. And as well from the perspective of the first ball dropped, the second ball will appear to be accelerating away from the first. and so will any other balls that fall into the well. This is similar to our perspective, in the Milkyway galaxy, of all other galaxies. So, this understanding begs the question, WHAT ARE WE FALLING INTO? AND, WHERE IS IT TAKING US????
The black hole equation says that, but I thought it took a certain amount of mass in order to make a singularity? Shrinking Earth to the size of a blueberry wouldn't change its mass, but just its size? Why would that create a black hole? I just can't wrap my head around that. Probably something to do with space/time being wrapped around the mass?
I once went to see an excellent Beatles tribute band. It was amazing! Their attention to detail and abilities to turn themselves into the Fab Four were absolutely mind blowing! Then suddenly at the show's end, one of the members unexpectantly went into a totally unrelated socio/political rant, alienating much of the audience who had paid admission to see and hear a really great band pay tribute to the Beatles, not to hear an unrelated and opinionated political lecture. Many got up and left. Nothing different here. This is a great presentation from Dr. Beacham. I will definitely listen to more. But when he goes political, I will simply get up and leave.
I mean, I imagine I agree with Beacham on some things politically - despite my critiques of the overly "woke" left, I do find the threat of authoritarianism more an existential one in that it never ends well, and at least now we can potentially vote out the politicians we dislike. Still, this was a physics lecture, not a political one and he should've steered totally clear of it, as that's not what people were there to hear and his apparent desire to have more of a direct impact on our current society via political action is one he can easily indulge outside of his physics work if he wants.
Since time curves near gravity fields of immensely high values, it's entirely possible that when you go into the black hole time moves in the opposite direction. What is actually collapsing appears to be expanding. Our universe may be collapsing, but we won't know because it will seem to take so much time that we will never notice it.
I have my own theory that there is no such thing as a singularity. I think Black Holes are just giant neutron stars. They are full of neutrons and they can't collapse because time stands still. Without time - nothing can happen.
Well, we could technically test this by using hawking radiation as our outbound communication method. Then if they on the other side deployed something into said black hole as a messenger to us I guess could work.
Super interesting about our universe being the inside of a black hole. Some logic seems followable but others seem to be upside-down. Definitely would want to check more maths besides what we can observe in our universe.
Yeah your right upside down but you forgot inside out so then the universe that is the inside will eventually pass the start point and be on the outside picture psychedelics

The best depiction of the maths behind black/white holes is through spacetime graphs. It's possible to plot the graph in the inverse on the extreme end of the graph and get a depiction of a white hole, almost like a mirror to the original graph. Check it out cos it makes a lot more sense when you look at it! Granted it is still only mathematical conjecture and no way genuine proof, but often times general relativity has been very sound when the hypothesised phenomenons have been examined in real life such as with gravitational lensing and black holes.
The idea of black holes as seeds to new universes is an idea that popped up in my head around 1986-87, when I was about 5-6 years old. And it has been my favourite explanation of black holes ever since. In fact, to me it's the only theory that makes sense. As a black hole sucks in everything around it over a time period of billions of years in our universe, on our "side" of it, it compresses all that energy into a tiny point in space. And the more energy it sucks into itself the larger the black hole grows, increasing its weight, increasing its size the more energy is consumes and compresses. Likewise, on the opposite side of the black hole all that energy expands, increasingly rapid. Time is relative, so what seems like a process that takes billions of years here, happens extremely fast on the opposite side. To me, this intuitively feels like the most elegant idea of what these mysterious things are. They ARE literally the yin and yang of everything, the duality of the existance. Light and dark, life and death, hot and cold, up and down etc. Even past and future, and everything in between. And it all came to me when I was 5-6 years old, just like that, with no real understanding of physics, without anyone else telling me about this theory and I never heard anyone say anything about it until about 10 years ago when Richard Dawkins briefly mentioned it in passing during some live Q & A with an audience that I saw here on RUclips. And I've never heard anyone bring it up since, until now, here. To me this is just the most logical conclusion when looking at what we know about black holes and the forming of our universe (which isn't all that much really).

I've done a fair amount of studying on black holes and astronomy/cosmology in general and I had 2 penny-drop moments during this lecture. Outstanding.
I've long been curious as to what passing through a black hole would actually entail. My current understanding is......if one were to enter feet first, the steeply rising gravitational differencial would tear one's legs off of their body...and probably tear the entire body asunder. This, of course would be extremely painful, but on the positive side, it wouldn't last long.

@@blackholeentry3489 I think that’s correct of a ‘smaller’ black hole. But in the case of a supermassive black hole, where the distance between the singularity and the event horizon is vast, from what I understand it would be theoretically possible for a human to enter and not be spaghettified/survive.

@@curbozerboomer1773 As long as people are dumb enough to vote for politicians such as Joe Biden, humankind will never truly advance.
What struck me is presenting the notion that the visible universe is just that, and there's stuff beyond that which we know must be there, and as it crosses over an event horizon and enters into our visible universe it expands our knowledge that much more and now becomes visible to us, but like a black hole we can never see beyond the event horizon. Just like being in a black hole. Absolutely mesmerizing. Bravo.
Me, too!
Thats also because light speed relative to us, and also because everything is moving away from everything. If I remembering correctly its about 100 stars per second disappering beyond our visable universe 24/7/365.25
This actually confused me because it's quite the opposite of what is happening; where everything red shifts and makes the observable universe smaller...instead you're saying we should be seeing more (already established) stars or galaxies shifting from infrared into visible light.
So glad I found this! This lecture is just what the doctor ordered for explaining the advanced theoretical concepts of what's occurring in astrophysics today in plain language. Thanks for posting!
Yes, he told you a bunch of nonsense and you ate it up. His mission was accomplished... it was to make you eat his garbage. ;-)
The prospect of each Black Hole containing it's own Universe is something I've believed since high school.
The way I saw it, Time, Energy and Matter get pulled in- but Time, Energy and Matter don't just disappear; they have to go somewhere, so the existence of multiple universes (and of White Holes) has been something I have suspected for the better part of 17/18 years.
I'm feeling a mixture of vindication, that my theory is shared by minds in the scientific community, and regret that I was never good enough with mathematics to actually JOIN that community and contribute from within.
Don’t let the regret stop ya!
Would you think that dimensions get collapsed like this? Like the black hole of our universe is 4d, so our universe is in 3d
I watched this now for the second time, after a few months realizing how true this could be. I gotten very fond of the thought we are in one and hope to find more connections over time. It even gives me hope it´s solvable, it´s all very encouraging. Somehow i have a feeling we are not gonna need a collider to proof things. We speed things up in another and much smaller device. Thanks for the presentation, very well put.
read my comment and see if you think it is another connection?
Perhaps we sit on the eventhorizon of a huge one. Observable universe is a eventhorizon of a black hole
If space can warp what is want. Time and light bend along with it, space appears straight...but it might be very warpy.
If it is this it would make so much more sense than something like string theory.
Wow, the concept that the universe is the interior of a black hole has just floored me.
Unlikely since we experience time in our universe and theoretically black holes are regions of no space or time.
I think it could not be because the black hole is probably extremly hot due to pressure from matter, you know... So hot that quantum particles get deconstructed or something. The equation for compessing visible universe into a black hole prroducing a black hole such and such bigger than the observable universe is just weird and unexplained to me...like the observable universe would be already more compressed than a black hole ftw
@@kristjan304 Black hole can be defined as an object with escape velocity higher than speed of light.
To use the equation for escape velocity calculation, with radius 50 billion Ly, our universe would have to have mass of at least 3*10^53 kg to have escape velocity higher than the speed of light (= be a black hole).
We cannot really see the light leaving our universe so either this equation is some subtle way of nature that shows us that universe expands faster than speed of light AND nothing can leave it.
Or, this whole equations does not work universally for very large object with very low density (but huge mass in total).
Question is, can we even think about Universe itelf as 3D object and apply on it same equation that we apply to stars and planets. In the end, the density of the universe is like... super close to zero. When put together, the mass would be huge, but in any random space in universe, you could feel no effect of it.
Funny part happens, if you think about the amount of mass as being constant. What will happen once universe expands so much it stops being a "black hole". Which should happen if the radius reaches over 160 bilion Ly (if the mass of universe is 10^54 Kg as in video).
Btw. i hope my math is correct, take it with the grain of salt :D
This whole looks like a semanthic to me about what is/is not a black hole, rather than real science :D
It could simply be that the calculation for the mass of our observable universe is grossly inflated or that the calculation simply don't work at such a grand scale
@@tomatodamashi I would really love to know how do they know the mass of our universe :D
Lets sum it up: Universe has billions of galaxies, billions of stars. Different star have different mass so you cannot really say 1 star = 1 sun. And stars are the easiest part, because you can detect them easily. Star system has planets, planets have satelites. Universe is full of trash from nebulae, asteroirds, dust, very small and very invisible matter. Even vacuum, believe or not is full of particles that have mass. Sure, it is only few particles per 1 m^3 but if you consider the size of f.e. our solar system, you can easily get tons and tons of particles.
You can find the amount of matter varying from 1^52 to 1^54 but still that is just the estimate.
Anyway, problem propably lies outside of the weight of all matter. I would say that used equation is wrong and cannot be applied to huge object that have huge mass, but also super low density.
I wonder if Schwarzschild radius was ever proven. I think it is just a theory with no real proof.

The way he explained crossing the event horizon, a terrifying point of no return, felt like me facing the consequences of procrastination. Ironically, I started watching this while procrastinating. But ended up galvanized and inspired by his vision of inching forward toward progress on a cosmic scale even though we'll never cross that horizon. It's about the daily millimeter forward, both for its own sake and for the infinitely larger long term goal of broader awareness, knowledge, and benefit to others beyond my current capacity to imagine.

Well....that took a turn there toward the end.
Not against what he’s saying but kind of detracted from the overall presentation and the information people leave with
It didn’t take a turn, he basically said if we don’t get away from where we are currently headed we will NEVER succeed in exploration of anything outside our world, solar system, or the universe. And he’s right, progress has slowed down due to the factors he talked about, and if we don’t leave those old ways behind we won’t get anywhere.
He said literal fascism... What did he mean by that? LOL If these clowns want to feel morally superior to everyone else, they need to act morally superior to everyone else. Not just virtue signal nonsense for one minute out of the day while the remaining 23 hours and 59 minutes per is devoted to their own egocentric pursuits...
He’s drinking the coolade, otherwise a great presentation
@@OneStripeRyan Yeah, it was a turn for the worse. More unfounded self-righteous ramblings.
Very informative and insightful. A scientist with an excellent story telling skills. I really enjoyed it.
Omg. James is such a good politician - selling black hole research to poor people by telling that would explain why there are many overly rich people. Especially when ( I think ) such research is mostly done using tax money. And as far as I know rich people knows very well how to avoid taxes - thus not really sponsoring this and other researches.
One thing that came first into my mind when watching this was: what about redshift. Most of the astro videos tends to agree that many many galaxies will float away from our visible universe not float into visible universe. I. E. Visible universe is expanding not shrinking into. I understand that when we apply spagettifying concept on large scale from inside out we could see outer edges eacaping with speed more that speed of light, just because we are falling into ourselves (our black hole universe) with speed greater than speed of light.
That would mean that somewhere in our universe is the center of black hole. It is most probably somewhere outside of vsiible bubble. But I must assune that it must be the place of most recursive black hole in our universe. What is the recusrsion limit?
Another thing - how do you guys know that artificial collisions are 1:1 to collisions in outer edge of atmosphere but with smaller scale maybe superconducting magnet mambo jumbo adds some weird spin in dimension that we cannot observe directly but increases invisible mass and when this invisibille ( for us) mass collide - you actually get invisible ( for our instruments ) black hole. And then they merge together until one gets big enough to attract matter that is visible for both (sets of) dimensions.
Also why would physics differ between outer universe and inner one? Only thing that should differ is perception of time?
About black hole collisions detected by scientists recently.
If black holes could contain smaller black holes. Without violent explosion. But two similary sized black holes creates explosion. That can be detected by shrinking space millions of light years away. What would it for us when our (black hole) universe collide with similar size (black hole) universe? Would we even feel that? C is maximal speed of everything so when such huge bubbles collide it still would take billions of years for them to be completely "informed" about the event. When thinking about it black hole event Horizon probably forms outside of both black hole galaxy bubbles even before to they merge.
Fascinating. I was thinking it is possible we are living in black hole universe before. But it makes more sense now.
Also avout rich people and black holes. Isnt it all about "that distribution rule" which is present everywhere. Sorry forgot how ot is called but if something can be in different sizes - then there will be much more small ones and less and less huge ones. If we apply that rule ( name is somewhere in standup maths videos) and insert currently assumed galaxy core black hole count then we could calculate number of small scale black holes and see how probable is to find one in our solar system outer edges.
Awesome lecture! Learned much about gravity, black holes and the potential for mini-black holes. Thanks. Hope to see more from Beacham.

I have thought this for a very long time. I’m glad an actual scientist has articulated just how that might be possible. I believe it’s true and one day we will have the black hole universe theory.
Really beautiful and uplifting talk, simply fascinating. I have no idea why this room wasn't packed to the gills.
Got to say that the fact this is done in England makes me so happy that we've got people like him making us think on a bigger scale of understanding. This was such a great put-together 👍🏾 thank you sir!
Yea but he’s American. Just saying.

I hope James enjoys living in England, but remember this. Science is universal, we are on this planet to grow and change.
So much politics at the end.
"The moon should be protected from commercial exploitation"
... Ok
"But we should be allowed to build our facility around the whole thing"
.... But why? Why are you allowed to use the moon but others not?
this was a very interesting presentation. So many questions that still have no answer . Dr. James is amazing. I'm just now getting into the science of our universe. Every video I watch and every book I read it leaves me wanting more and more every time!
Well said!
Actually, the answers to these have been found in more recent Quantum research. Check out Dr Nassim Haramein.
That’s great to hear!!! Keep at it! We need more people like you involved in learning science

@@rpow6861 Agreed. What a towel.
This is the first time I understood how we could possibly be living in a black hole. Simple, to the point, explanation. Bravo!
😅😅😅😅
Explained? The hilarious thing is that Einstein's space time doesn't explain anything. Instead of these things attract, we get this absolutely undefined "space" bends. What bends um.... What is this fabric of space? And then us being on a spherical planet, how do we feel acceleration outward from the center of a ball, while someone on the other side does the same? Ever accelerating expansion of the earth😂. Then we take that obviously flawed theory and extrapolated it to get stuff expanding faster than the speed of light even though the model starts with nothing can go faster than C. And we are left with this model not explaining the space time fabric that does all the heavy lifting of the model. It just does even though it's own parameters say it can't.
Are we living in a Cardboard Box?
@@chrisoakey9841Einsteins field equations aren’t undefined, they are precise. You are rubbishing one of science’s best theories, simple because you don’t understand it. You have completely misunderstood both Special and General relativity
@@Amethyst_Friend the equations are not undefined, though the assumptions flawed like light doesn't slow. but the fabric of space is undefined. you see, the Michelson-Morley experiment, dismissed ether as the fabric. so what is this space thing? the fabric of space/time is claimed to be compressed. but what is this fabric made of? and what proves it exists at all? it's ability to deflect is the basis for time dilation. but what is it. not atoms, or quantum bits. we are just expected to move past this giant missing piece. it is up there with dark matter being everywhere and 20* more common than other matter, but we just can't find any of them.
- perhaps i don't understand. because so far, the responses are that you can't question Einstein. but so far no one has been able to explain what space is. so if you can define what the fabric of space is made of, i'm all ears.
Amazing talk. Could those giant cosmic voids be one part of what happens when a universe like ours is born from a black hole, as opposed to being a black hole where everything gets crushed into a singularity?
The thing that makes me feel extra insignificant right now is like...what if we're only on a very tiny, thin little circle inside the event horizon where our laws of physics remain stable? What if the event horizon is so huge that even a blip of falling into it is the entire lifespan of our stable-ish observable universe?
I am high
me too and whoa, that would be sickkkkk
Once you let go of ego you no longer feel insignificant
Why do you need to feel 'insignificant'? You should feel Grand, to know that we exist in a world that is Grand and is trying to teach us amazing things about everything everyday. We should be proud to even exist and can explore and learn, and to enjoy the process of learning about the Universe and beyond.
@@supertuesday600 true! We really were born at the perfect time to observe the universe, as well
But aren't we falling to the black hole as we get attracted towards it , so don't we make that blip like every year or so
I like this fractal approach to the explanation of reality. Because it's already what we observe in nature close to us. So why not at any scale, even the most enormous ones.
I love fractals, while not proof of any grand unifying concept, I still believe that they can provide some amazing food for thought. They are both remarkably concept and fundamentally natural.
James Beachem you are the consumate Physicist, walks and talks the talk of Physics so coolly. I like it!
the biggest shock to me out of this whole experience is that auditorium has empty seats .... outstanding .. just brilliant.
It was full until 52:58. Everyone left when politics materialized out of nowhere and babble ensued.
Not a single chuckle at his dry jokes haha.
It just seems to be empty, the fabric of the auditorium just expanded… :)
@@bjchandler8937 The hall was never full. Go back to to the beginning of the video and check. Why would you misstate the easily verifiable just because you disagree with his societal views? Such an unscientific response to a scientist’s lecture.
His presentation skills are at a high school level. It's a broad overview of some existing models and theories, sprinkled with unverifiable conjecture and wishful thinking.
The most interesting part of the entire speech was the testable portion at the beginning: If there is evidence for a dark body of substantial mass in the solar system, we could in fact try to intercept its estimated path and measure any gravitational deflection of the probe's course. I had hoped for more focus on this subject.
Being a lay person, I have no way of wrapping my head around some of these ideas or concepts. But I do have a question: What if we sent an object that was entangled with another object? Would the second entangled object react to what the one traveling into the black hole is experiencing?
What is intricated in the spagetti sauce? A tomato scream.
If there is one thing that could untangle the two entangled objects it would be a black hole. Because an object that enters a black hole would undergo radical transformation as it's physical properties were seperated and stripped from its subatomic particles. It's where matter gets converted to energy so the connection between the two objects would become unstable and disrupted as one of the objects began to lose the unifying properties shared by the objects during entanglement
This is, in part, Lee Smolin's idea about universes reproducing through black holes. The "fecund universes" hypothesis might be untestable, but it explains so many phenomena at the same time. It is elegant, in other words, and parsimonious. For example, the same fundamental constants for life and for black holes are identical, so this would mean that cosmological evolution explains the anthropic coincidences perfectly (universes that are good at making black holes--i.e., good at reproducing--are also good at making life). And the math works (I'm told--I can't math to save my life).
According to general relativity, the immense gravitational pull of a black hole compresses matter and energy to an almost infinitely dense point, known as a singularity. While this implies that anything crossing the event horizon is essentially lost, some theoretical models suggest that black holes could be gateways to other regions of spacetime or even parallel universes. Another possibility is the existence of "white holes," hypothetical objects that expel matter instead of absorbing it, though no evidence has been found to confirm this. Advancements in quantum gravity and string theory might one day provide a clearer understanding of what happens beyond the event horizon, but for now, the other end of a black hole remains one of the great mysteries of modern physics.
Fantastic right up until the end.
Yup started spouting BS like the oceans are burning...which they are not...
100%. I was all in on that great lecture…BUT as soon as he brought up that lefty snowflake BS, I was done.
He didn’t say anything inaccurate.
@bradonhassell5567 you may think that, but about 50 percent of people disagree, which is why its bad form to get political in a lecture like this. It detracts from the very interesting and intriguing point of the lecture and alienates half the audience while adding essentially nothing of value to the lecture itself. Its very frustrating, even to many who agree with his political message, but especially to those thst dont.

Question for those with superior intelligence to me: Although its likely that entering a black hole can destroy all life, Is it possible that life can begin again over time, inside the black hole using all the material and matter that had been sucked into it previously?
Hawking radiation
I do believe that is the point.
There's a video on a channel named Kurgezagt regarding the question you asked. Check it out
@@khizzard_069 thank you
Depending on the size
THERE IS NO OTHER SIDE.. PERIOD. Anything going in is crushed to a point.. There is no coming out somewhere else. Because if that were the case then the black hole would not be as heavy.
It would be like me putting items into a shopping bag and the shopping bag is the back hole. But if the bag has so bottom then the bag holds no weight, and if that were the case then the bag / black hole would not be bending space.
Whatever goes in does not come out, it's crushed to a point smaller than an atom.
And as for light being the fastest thing in the known universe, now we have a black hole acting like water or space going down a drain. A drain that even light cannot escape. This means that light is not the fastest thing in the universe, but rather space it's self is faster.
I always thought this… myself. I’m not a physicist. The Big Bang was a black hole… but the OTHER side of one. Infinite universes. All interwoven by black holes.
Agree
But we can never come out of our black hole.
White hole?
Exactly! There is no limit to what the mind can imagine, as long as one is still able to distinguish between what is real and what is imaginary. Voila! You have entered the creative world of art.
I had the same theory but couldn't explain how it worked as I'm not a physicist.
This is the first time the concepts of dark matter and dark energy have made sense to me
I always knew black holes were gatekeepers, but I had no idea they were so exclusive. It's like they're the bouncers of the universe, with a strict one-way policy. But I have to admit, the idea that our entire universe could be inside a black hole is mind-blowing. It's like the ultimate cosmic nesting doll.
I was thinking the universe was the output of a blackhole - what falls into it gets spat out the other side into a universe. I suppose this is essentially what he is saying.

@beacham here are a few hints:
Assume existence is uniform and tends to infinity in both the small and the big. i.e there is not such thing as plank constant. It just goes smaller and smaller to infinity
The universal law of big numbers
The laws of thermodynamics
Genrealization of infinity postulated by Richard Feynman.
We only need to be certain that no matter what the limit is, but there is a limit to infinity
Although we cannot understand infinity, we can understand its gradient.
If you toss a coin an infinite number of times, the number of head and tails will be exact
A photon will go through both slits only if it is made of infinitely small particles.
Dark matter is probably this part below the plank constant that we never considered
I don't know why, but relativity was required to understand why newton's law works. Now that we know, Newton's laws should be used
Basically, the laws of thermodynamics and the laws of motion should be enough to model everything. Provided that the universe is a closed system. or at least for our perception
around 26-27 minutes my mind was absolutely shattered
10:57 This is the 1st time I've heard someone talk about the flow up until now I've only heard about it bending space time so thanks. It makes way more sense now
It has always been a bit fraustrating to hear popular science hosts explain things in misleading ways for the sake of simple understandings. This guy did a great job, but I wish he would have shown better graphics to fully grasp the flow of space. I would recommend looking up the 3D model of gravitational space flow. You always see the stretch sheet with a heavy ball example but its so simplictic that it leaves a false impression of reality.
@@jeremyn4397 I looked up 3-D versions of gravity but they're all just a spacetime warping and not flowing inwards
His presentation is also misleading: the "flow" inside a black hole is stretching the proper radial directions and squeezing the perpendicular ones, so the final singularity cannot be a "point at the center " as he claims... It is in the future for anything that falls inside.
Black hole singularities are spacelike "hypersurfaces" when time comes to an end ( more accurately: spacetime comes to a self-destructing end), not "points"!
This is a very common misunderstanding ( obviously he's not an expert in General Relativity)
@@dimitrispapadimitriou5622 it is not a point 2D a ring surrounded by the ergosphere. All black holes are spinning. What happens here is called frame-dragging. I don't understand how talking about space-time flowing like a fluid (as it should) is misleading.

The Singularity (according to GR) is labelled r=0.
This is not a point of course it's a Spacelike hypersurface that cuts off the future everywhere in the interior.
( If you're interested, check a Penrose diagram of a typical non rotating black hole from a collapsed star.

“There are some ideas so absurd that only an intellectual could believe them.”
― George Orwell
I think they're all wrong. Gravity is not a force that pulls you. I think gravity is a force that pushes. Gravity is a byproduct of the reaction of dark matter with the physical world.
Newton's 3rd law say the forces between two masses are equal and opposite. However, when you fall towards the Earth the earth doesn't accelerate towards you at the same rate as you do toward the Earth. The answer would be the mass of the earth is so great and because it is so great it displaces more dark matter. The displacement of Dark Matter by physical matter causes gravity.
The forces that accelerate you toward the larger body are a result of Dark Matter trying to reclaim physical space. The byproduct of this interaction between mass and dark matter provides the force of gravity. Which is different from the forces the objects have on each other based on the product of their masses and the inverse square of the distance between them.
Collapsing a Mass of any size can trigger a dark matter response. That includes a collapsing star or a single atom. If you want faster-than-light travel that's the way it will be done. Collapsing matter around an object can give that object extraordinary burst of speed without generating the corresponding Heat or G-forces even when done in atmospheric conditions.
Acceleration can create artificial gravity but it is the object's Mass displacement of dark matter that contributes to real-world gravity. These two forces of attraction can work together but dark matter flow is the dominating Force.
The universe is swimming in a sea of dark matter that is constantly in movement. Because its density is not uniform that also provides an opportunity to open up wormholes. Like water dark matter flows towards areas that are less dense. That gravitational flow can be created any time a mass collapses instantaneously. This sets up a dark-matter Cascade. Matter isn't pulled into a black hole it is pushed into a black hole.
Like water causing a dam to collapse. The dam collapse is not because of forces on the dry side of the dam pulling. The dam collapse is because of the forces on the wet side of the dam pushing through.
Dark matter has the same characteristics. Dark Matter pushes everything into a black hole as it makes an exit through the black hole seeking an equilibrium. Like being pushed over Niagara Falls when you get too close to the Edge. The difference is the Dark Matter flow and the material it carries into the black hole with it can exit hundreds of billions of light years away adding to the expansion of the universe.
I suggest you throw out the laws of physics as you know them. A perfect example of those laws being obsolete is the observation of our tic tac maneuvers that have been observed by military Pilots. Those objects effortlessly defy all the laws of known physics. Those objects have no need for aerodynamic flight surfaces, they don't produce a heat signature, and G-forces are irrelevant.
I don't believe the world is ready for these advancements. The ability to use these concepts to create black holes, open up a wormhole, or greater than light speed travel could be devastating in the hands of primitive humans. However, it's the chance we have eventually got to take.
Gravity is a force created by dark matter trying to reclaim physical space occupied by matter. A wormhole allows Dark Matter to flow out of this universe into another parallel universe or to a distant part of this universe where dark matter is deficient.
A collapsing star or a subatomic particle causes a rapid decline in the amount of space that matter occupies. That sets up a "Cascade Effect" in the dark matter surrounding the star or particle.
The density of matter has a direct proportional effect on dark matter that surrounds it.
If all the known mathematical formulas for Gravity are combined in the symbol "N". We can then say that this concept of gravity would be represented by the formula
Gravity = -1(N)
Dark Matter does not exist, ffs.
@@pentagrammaton6793 I think Dark Matter does exist. Not only that I believe dark matter and it's interaction with the physical universe is what causes gravity in the first place. It is my hypothesis that dark matter is the medium in which the physical world exists. It is the invisible ocean that the Universe swims in.

lol. you got your PhD from RUclips University. blackholes are not real.
@@shaquadradeloiserussell8659 Judging from your statement there's a black hole between your ears.
Bravo! Best use of an hour I've had for some time.
Of course!! Gotta push your serious agenda!!!
It’s a totally mad idea but he is definitely on to something
the whole idea of another universe being within a blackhole is something I've thought about many times, and I've heard pondered by others as well, but just a thought experiment. The fact that some mathematics points to that being a possibility is pretty nuts. But I have thought about how a black hole appears in an instant and how similar it is to a black hole. And I think I've even heard physicist's say that the same thing that kills black holes would kill the universe, which is essentially the cold. The very very very very cold, which causes everything to slowly lose energy.
But if the universe is expanding, doesn't that mean it is eating matter in the surrounding universe? And the event horizon would be glowing and the universe should be brilliant and hot. Except that it expands faster than the speed of light so the light never reaches us? That is my take away and the implication is that if it stops expanding, the universe becomes brilliant and prone to heat death
@Ian Maxwell As he explained the universe is Not expanding in the Normal sense, but rather Space is expanding!!
@@JohnDoe-qz1ql same thing in practice. Yes the expansion is occurring across the entire continium rather than just from the edges but a. I realise that and b. It has no bearing on what I said.
2 things definitely same about the black hole and the edge of the universe is that: Once you fall into a blackhole you can never come back; Once you go beyond the edge of the universe, you also can never come back because the edge of the universe is moving away faster than the speed of light and nothing beyond it can be seen, just like inside of a blackhole. Time ends at these 2 places.
instead of saying "very very very very very cold"the term your looking for is absolute zero.
Great lecture. Thought provoking. Thank you
As soon as you were born you passed the event horizon, there is no going back. And when you pass away you will experience singularity no space and time.
Trippy
That’s deep bro
Too bloody right
Where you get stuff to build anything that big?
When is your Ted Talk?
This guy is fantastic! Thank you so much!!
There's a major question that needs to be answered before we can make any headway with quantum gravity. If you have a quantum object, the position and momentum are uncertain. Is the gravitational field surrounding the object also uncertain? Penrose expressed that gravity might cause wavefunction collapse. If we can get a large enough object to behave as a quantum object, maybe we can detect some strangeness in the gravitational field. Or, maybe we can get some information from neutron star spectroscopy, looking for gravitational energy shifts.
I bet there are some amazing tests of that concept coming up with BECs
Yes, that means the gravitational field is uncertain. Or in more modern lingo: the shape of spacetime itself is uncertain.
That pretty much sums up why these two theories haven't been reconciled yet.
The idea our universe is inside a black hole is fascinating. Time will tell.
It likely won't
or not
Is there anyway to ever know that? Likely not.
I loved this talk. And I don't want to sound ignorant, but I have a couple questions. 1. If black holes consume everything around them, making them bigger and bigger, consuming more and more, then how could one be the size of an apple just hanging out on the edge of our solar system? Wouldn't it be constantly growing bigger, eventually pulling our solar system into it? 2. Regarding getting sucked into a black hole and turning to spaghetti: Wouldn't that only be an illusion due to the observers position in space-time? Like, I would look around me and everything would stay normal, but to someone on the outside, I would LOOK like spaghetti or frozen forever on the edge only to an observer who's space-time was not being sucked into a black hole. 3. Regarding the possibility of being inside a black hole: absolutely. Because it is certainly possible, we are talking on these enormous scales of time. If black holes grow and grow and grow it is inevitable at some point eventually they would just get so huge and consume everything. But if this were possible and we are on the inside already, then we know that although they consume everything eventually in one universe, they will create another? Or maybe we pass thru unscathed and the noodly legs are again due to perception.....But the point is that I am most likely not understanding an aspect of black holes, or it is inevitable and when viewing at this huge perspective, it is not only inevitable, it has probably been happening gazillion into infinitude....which makes more sense than a big bang. a big bing gives us this like starting point out of a singularity all this crazy shit started to happen. Why tho? Why and doesn't it violate one of the most basic laws of physics that matter cannot be destroyed only changed into a different form? How could something happen from nothing, like the grand Nothingness?? In terms of the grand reality, doesnt it make more sense that there would be some kind of mechanism that could transform one reality or universe into another reality or universe over and over and over? Is ALWAYS a real possibility? Is it possible that this has ALWAYS been going on, there is no start or end, only from the perspective of an observer on either side? And what would that look like from our perspective after passing thru? I mean, we went into a black hole, so now we are here, when we look back to where we came from, what would that look like?? It might look like a start, because in a sense it is the start to this space-time reality,
I would love to hear this guy talk about the different types of black holes more, spinning vs static black holes, their charges, black holes made from light rather than matter, ring singularities vs point, ect. Would be facinating.

Great and very interesting lecture! Thank you Mr. Beacham! 🙏
Absolutely brilliant. Goodness gracious, I didn't learn this much in all my school years than what I learned in this 1-hour.
Ah ! Wish I could go back in time and do better at Physics and Math.
Your lecture very interesting. Sadly I’d have gone to the Albert Hall or the Royal Society! To watch live. And get to ask my question. But these events are never properly advertised. Great effort prof
We have lots of upcoming in person events at our London home if you're interested in coming along! You can see them at www.rigb.org/whats-on
If two particles become entangled, one gets gobbled by a black hole, will entanglement remain? Could this be used as a basis to communicate beyond the event horizon?
One of my two particles got gobbled by a black hole one time. I wouldnt recommend it.
You can't use entanglement to communicate: you can't force your particle to resolve in a particular way - it's just random. You could use it to coordinate, but that's about it.
What happens to entangled electrons if we send one of them into event horizon and we change the spin of the other one outside the black hole. Does the spin of the "black hole electron" change? Does quantum entanglement work even in this scenario?
1) Once u forced-change to the spin of an entangled particle, the entanglement breaks down, and the other particle's spin will be random (50/50). So it's not possible.
2) You will also never know the state of the other entangled particle that went inside the blackhole, because any information about it can never be observed by those outside the black hole.
Not sure if your description of entanglement really nailed it, but that's not important. Why would entanglement work any differently just because one e- is now in the black hole? The only problem is we can't check it.
Excellent talk, all very clear and explained. Thank you for your message at the end, it is indeed needed.

Incredible presentation!!
...until the end.
I find it unsettling that so many find the need to shoehorn in political messaging wherever they can.
As the sciences are about unbiased facts and data, and not personal feelings and opinions; I feel the content of the conclusion was neither the right time, or place. Let's keep the realm of world politics and climate change to their own lectures. I respect all opinions, on all matters. However, the situation our world finds itself in, is far more complex than a few, well-worded metaphors.
Regardless, excellent and very well done presentation!
Bravo!
You're still getting a thumbs up too.
All the best. Let's build that accelerator!
I admire the conclusion for its scientific perspective on the essence of life and the intended societal structure by a divine being (he called it nature). It highlights how human greed and malevolence have corrupted these ideals, leading to societal issues like power imbalances, conflicts, and dishonesty. We're approaching a critical point akin to a figurative event horizon, symbolizing the ultimate consequences in the afterlife where accountability awaits. This concept aligns with the scientific discourse on the potential outcomes of human actions and their repercussions.
Certainly! Our existence seems purposeful, void of randomness. We're here to prove our worthiness for heaven or hellfire in the afterlife.
This guy was doing so good, until he completely sabotaged himself by making his presentation into a woke propaganda piece.
The first 52 and a half minutes were great.
Very inspirational and quite possible, I believe. We are currently very, very out of balance. Thank you for your time, effort and passion. Great rising to you!
Getting even more out of balance with fairytales from Quackedemics like this one.
I commented this above, tell me what you think.
So, I didn't watch the Entire lecture, but I think this is the one I've seen before. He is the first person that I have heard explain that we live in a black hole, and not to toot my own horn but I came to this conclusion about 10 years ago. The way I realized this was something I thought he would have touched on, but he didn't. Anyhow, the evidence came from when scientists noticed all the galaxies are accelerating away from each other. So, consider this example. You drop a 1lb. iron ball into a well that is a vacuum and bottomless. It just keeps accelerating, then 1 second later you drop another. from the perspective of the person dropping the ball into the well you would see that the first ball is accelerating away from the second ball and therefore the second ball will never catch up to the first ball, but rather always be growing distant from the first ball. And as well from the perspective of the first ball dropped, the second ball will appear to be accelerating away from the first. and so will any other balls that fall into the well. This is similar to our perspective, in the Milkyway galaxy, of all other galaxies. So, this understanding begs the question, WHAT ARE WE FALLING INTO? AND, WHERE IS IT TAKING US????
The black hole equation says that, but I thought it took a certain amount of mass in order to make a singularity? Shrinking Earth to the size of a blueberry wouldn't change its mass, but just its size? Why would that create a black hole? I just can't wrap my head around that. Probably something to do with space/time being wrapped around the mass?
I once went to see an excellent Beatles tribute band. It was amazing! Their attention to detail and abilities to turn themselves into the Fab Four were absolutely mind blowing! Then suddenly at the show's end, one of the members unexpectantly went into a totally unrelated socio/political rant, alienating much of the audience who had paid admission to see and hear a really great band pay tribute to the Beatles, not to hear an unrelated and opinionated political lecture. Many got up and left. Nothing different here. This is a great presentation from Dr. Beacham. I will definitely listen to more. But when he goes political, I will simply get up and leave.
But literal fascists and boiling oceans 😂
I mean, I imagine I agree with Beacham on some things politically - despite my critiques of the overly "woke" left, I do find the threat of authoritarianism more an existential one in that it never ends well, and at least now we can potentially vote out the politicians we dislike. Still, this was a physics lecture, not a political one and he should've steered totally clear of it, as that's not what people were there to hear and his apparent desire to have more of a direct impact on our current society via political action is one he can easily indulge outside of his physics work if he wants.
Since time curves near gravity fields of immensely high values, it's entirely possible that when you go into the black hole time moves in the opposite direction. What is actually collapsing appears to be expanding. Our universe may be collapsing, but we won't know because it will seem to take so much time that we will never notice it.
"Our universe may be collapsing"
Gravity is a weak theory. We are in an electromagnetic turroidal realm.
@@historysmysteriesunveiled8043 - Dark Matters !!!
@@historysmysteriesunveiled8043 - By the way... It's "toroidal field".
I have my own theory that there is no such thing as a singularity.
I think Black Holes are just giant neutron stars.
They are full of neutrons and they can't collapse because time stands still.
Without time - nothing can happen.
Brilliant presentation. Lost me for a bit when he wandered off at the end, burst that story bubble.
Well, we could technically test this by using hawking radiation as our outbound communication method. Then if they on the other side deployed something into said black hole as a messenger to us I guess could work.
Absolutely incredible. I knew this information, but never grokked it before today.
Passionate, informative and accessible. Many thanks!
usually females do not notice ideological statements and lies.
Could not of put it better 😊
Super interesting about our universe being the inside of a black hole. Some logic seems followable but others seem to be upside-down. Definitely would want to check more maths besides what we can observe in our universe.
Yeah your right upside down but you forgot inside out so then the universe that is the inside will eventually pass the start point and be on the outside picture psychedelics
Super interesting, if you enjoy pondering absurdities, I suppose.
@@NondescriptMammalwhy is it an absurdity? It could very well be possible. Don’t just rule it out before making sure you understand what the lecture is really thoroughly about. If you completely understand what’s being discussed here, then you probably would not say it’s an absurdity…

The best depiction of the maths behind black/white holes is through spacetime graphs. It's possible to plot the graph in the inverse on the extreme end of the graph and get a depiction of a white hole, almost like a mirror to the original graph. Check it out cos it makes a lot more sense when you look at it!
Granted it is still only mathematical conjecture and no way genuine proof, but often times general relativity has been very sound when the hypothesised phenomenons have been examined in real life such as with gravitational lensing and black holes.
The idea of black holes as seeds to new universes is an idea that popped up in my head around 1986-87, when I was about 5-6 years old. And it has been my favourite explanation of black holes ever since. In fact, to me it's the only theory that makes sense. As a black hole sucks in everything around it over a time period of billions of years in our universe, on our "side" of it, it compresses all that energy into a tiny point in space. And the more energy it sucks into itself the larger the black hole grows, increasing its weight, increasing its size the more energy is consumes and compresses. Likewise, on the opposite side of the black hole all that energy expands, increasingly rapid. Time is relative, so what seems like a process that takes billions of years here, happens extremely fast on the opposite side. To me, this intuitively feels like the most elegant idea of what these mysterious things are. They ARE literally the yin and yang of everything, the duality of the existance. Light and dark, life and death, hot and cold, up and down etc. Even past and future, and everything in between. And it all came to me when I was 5-6 years old, just like that, with no real understanding of physics, without anyone else telling me about this theory and I never heard anyone say anything about it until about 10 years ago when Richard Dawkins briefly mentioned it in passing during some live Q & A with an audience that I saw here on RUclips. And I've never heard anyone bring it up since, until now, here. To me this is just the most logical conclusion when looking at what we know about black holes and the forming of our universe (which isn't all that much really).
This guy somehow turns black holes into a anti capitalism rant 🤡 and the apple part reminded me of Michael Scott 🤣
I like the way he explain things. He makes complicated things understandable. Can’t wait to see more of His talks.
Wow, I did not see that coming. Utterly brilliant. I’m covered in goose bumps and hope we heed your warning.
"Regular impossible is impossible right up to someone makes it possible"
amazing sentence. good job James Beacham!
