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.

It makes total sense to me, folding upon itself, from itself. Like the mendlebrot set. Like cellular growth, the universe expanding... all interfolded and we'd be like a petal of a flower, each petal expressions of each other but also the plant. I'd say it's our perception also as quantum mechanics describes, we can't decide what petal we are, so to speak. Which describes tunneling very well.

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.

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.

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

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?

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

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.

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?
SuperTuesday
SuperTuesday 2 aylar önce
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.

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).

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.

If we are in a black hole, might the reason the center looks black is because we can’t look out? Perhaps the event horizon works both ways. We can’t see light inside or is it that we can’t see light outside the black hole. Also, I was wondering that since radiation jets come out of a black hole, is it possible that anyone who goes in… could somehow manipulate those radiation-jets? Would it be possible, perhaps some kind of pulses could be passed to the outside/inside…like a morse code?

The idea that our universe expanding faster than it should be lead to the idea of dark matter/dark energy. Could be the black hole feeding and physically expanding as it adds mass to itself. This moves points along just like the rubber stretching points you'd explained. As black holes can eventually evaporate at the end of their lives, points would get closer together and possibly crash into an impossibly small point. Sounds like expansion/compression theories and the big bang. Crazy how similar they could function!

It's just an incredibly huge mass in a small space, with such a strong gravitational pull because of that mass in that confined space that it absorbs/ bends light. There is no 'other side', unless you mean the other side of the event horizon where anything passing is ripped to shreds by extreme gravitational forces.

It was mentioned during the lecture the weakness of gravity compared to the other 3 quantum forces is unexplained. Earlier you provided a description of black holes as possibly a connection to other universes. Why isn't the gravity weakness explained by "leaking" gravity to other universes via black holes? If Occam's Razor, the notion that most often the best explanation is the most suitable, is a valid tenet of the scientific method, why not look to that as a solution to the general relativity and quantum paradox?

I really appreciated this. I listen to a lot of these talks hoping to get a little more each time and I because I have heard so many I feel I may be either be reaching the point of diminishing returns or finally as in this case getting a little lift up off of my current plateau. I am thankful to Mr Beacham for that. I have to say I disagree with the thrust of his political summary though. Right now we are enjoying a technical renaissance that I am quite sure will benefit the field of astronomy as well as help finally wean the human race off of it's addiction to fossil energy and that has not happened because politicians legislated their way to it any more than politicians could legislate their way to Mr Beacham's genius. It is because some companies have found ways to make alternative energy technologies and space exploration technologies economically viable. That was never going to happen if we were going to have to keep on relying on the US congress to fund the projects we need. That said, I really love Mr Beacham's work and considering his youth I am sure I will be enjoying watching his career grow and flourish till I die.

More massive does not mean larger. The common E=mc^2 is actually only part of E's famous SToR equation - and the fact that the other half of the equation too often gets lopped off often leads to some confusion. The full equation accounts for relativistic mass - whereas the E=mc^2 part is for stuff that is not moving - better, moving slowly compared to the speed of light. Think of that as the additional 'mass' something picks up as it gets close to the speed of light. That's why mass asymptotically tracks towards infinity as something approaches the speed of light - and also why anything with mass cannot be accelerated to that speed.

I've been saying this since the 1970's, when I was studying for my HND, and beyond, but every time I state it, even 'experts' say I'm wrong; it cannot happen. But this guy is saying it, and people are agreeing with him. So glad that I'm not the only one who thinks this way. The concept is simple, explains the way a universe can appear to be infinite to internal observers, explains microwave background radiation, resolves the cosmology crisis which people try to explain by 'dark matter' and 'dark energy', allows for universes within universes, and doesn't require an 'outside' in the way we normally consider it. The whole of creation is a cascading web of interconnected black holes. There is also no need for a 'beginning' or 'edge' that we could imagine easily. It doesn't actually matter; there is nothing we could experience directly from outside of our universe. Our 'Big Bang' was the point in spacetime when a black hole was formed, and since you could never accelerate towards the 'skin', which is the inside of an event horizon, that horizon appears to be an infinite distance away. For an 'outside' observer, they would experience the accretion disk and near-event horizon of a black hole within their universe. Infinity is a complex concept, unless you accept this theory. Once you do, some aspects of it become very simple to appreciate.

could also explain why everything has parts of a dead star in it, would it not? since the black hole formed (most likely) from a dying star.. but maybe the universe doesn't need to be a black hole for that to happen, but it was a thought. I also wonder, how then does a universe within a black hole accept new matter falling into the black hole, would it just appear somewhere within the universe, come out of some kinda of opening we cant see, or sprinkle out the particles of whatever the thing was made of across the universe? And, what if the space our black hole universe is in becomes to cold to support the black hole? or what if its swallowed into a larger black hole? So many questions

@John Bluehouse The "liberal speak" did feel like it was a quick and unexpected turn away from the lecture. But, I think he was fairly clear about what the "Societal Black Hole" he was referring to... The growing inequalities of society, specifically the wealth inequalities where a smaller and smaller portion of the population is gaining a larger and larger portion of the wealth. And that wealth is used to concentrate more power to that central, wealthy minority through exploitive behaviors. Very much like a black hole, this central, wealthy minority only consumes and exploits everything around it, be it physical resources, monetary resources, or human resources. And he is simply saying, these are human made issues and we could change our societal rules so that these exploitive behaviors did not incentivize a centralization of the power and wealth of the world.

The visible universe | black hole idea is exciting, I wonder if a string of probes/ships were sent over the event horizon, would their 'event horizon' from their perspective be different from the outside observers but relative to each other, if so (and presuming you have enough of them at a suitable distance from each other) their Venn relationship would allow them to maintain communication with one another all the way back to probes/ships outside the black hole's influence ?
SuperTuesday
SuperTuesday 2 aylar önce
Once you go over the event horizon, you lost communication with the outside. From inside perspective, you might feel normal, but you can never get any signal from outside because you are 'moving' faster than light or any signal that can reach you, because the spacetime is so curved towards the center of the blackhole. Also, for the same reason, nothing or any signal can travel out of the event horizon. So no matter how many probes you string together through the event horizon, communication will definitely be lost at the event horizon.

Dr. Beacham -- brilliant experimental physicist and superb speaker. I love the lecture! Having said that, here is another example why scientists should not get into politics. He is essentially speaking against the future (or contemporary) Christopher Columbus of our society, that will lead us to new worlds, and new opportunities. Columbus had to go from one king to another to raise money for his dream; and the wealth of his discovery is projected and impressed on our social, economic, intellectual fabric as humans. The Elon Musk and Jeff Bezos, and the like of our time, will lead humans to the next adventure that will have even greater impact on society. America was not discovered by the peasants nor the knights, nor the kings of the middle ages, but by the dreamers who risked it all. Sure, Columbus brought misery on the natives of America -- but misery existed in Europe too. Unfortunately not everyone along the way shares the richness of new discoveries.... some fall victim (and this is truly unfortunate). The richness from mining the Moon or the asteroids, or from permanent habitation of the Moon or Mars, will benefit humanity. There will be some who will fall along the way. But progress has a price. Dr. Beacham has a distorted view of the social world.

But it’s not just one voice that is talking about their past beliefs. If you pay attention carefully you may only hear one voice talking about their past beliefs at a time. But if you talk to multiple people you will see that multiple people have the same past belief. Such as Chick-fil-A used to not have A c I remember at Chic-fil-A. Many other people remember it the same way as well. Maybe it is just a coincidence that we all remember it wrong. More than likely we have big egos. It must be our egos. There is no other explanation not even from watching this video should I get that explanation. Unless possibly this particle collider is pulling threads out of space and time and reversing space and time for just a couple of people.

Love that he begins by saying "we dont understand what happens at the smallest scales below the planc length, nor what the properties would be of the extra dimensional pockets that gravity resides in, but dont worry, if we produce a black hole at the LHC it will instantly evaporate and be no problem". He's 100% unsure about how the fundamental deepest layers of the universe works (naturally). But when talking about potential planc-length black holes, he's suddenly 100% confident about the outcomes. lol

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.

Gravity is a consequence of the interactions between the higgs field and the soup of spacetime itself. Spacetime is actually more dense than matter thats why matter tends to clump together. The push of the week nuclear force within atoms weakening or wobbling spacetim around the given object softens space and makes the spacetime near the object less dense than spacetime further away from an object. pull of the magnetic attraction of particles within the higgs field and the density of spacetime all combine to create the illusion of gravity. Thats why two flat objects in space will weld together. The space in between is weakened by the nuclear forces of the objects and the density difference causes a shift in forces making the objects drift together as spacetime in between flows out and is replaced by the less dense objects made of matter.

8:00 im 37 years old and been following astrophysics all my life. Just by choosing the word "flow" instead of "bend", you completely change the concept. And i've never before heard anyone else describe this with the addition of spacetime "flowing" like a river or whirlpool. This makes a lot of sense, if that effect is prominent enough, couldnt that explain why galaxies are kept together despite the static gravity of the accumulated mass not being enough to prevent stuff spiraling out? If the accumulated matter moving in the same direction also results in spacetime itself "flowing" like a river, adding some traction to let stars move along with the underlying framework, wouldnt that explain, in part, how the galaxies are kept "sticky"? Is dark matter really needed, or is our understanding of gravity just incomplete in this kind of concept?

I love this presentation and was floored at the idea we may exist inside of a black hole. It would explain why space is expanding faster than the speed of light as the event horizon grows. One contention I have with one theory is.....claiming there is actually no such thing as gravity/gravitational force. All the while using G (the gravitational constant) to calculate the Swartzhild radius To me this is the equivalent of suddenly saying there is actually no such thing as an invisible force called magnetism, yet still using Gauss as a measure of Magnetism.

This mind boggling! So the Great Attractor, or a larger mass beyond, could be the singularity, which is what we & all local galaxy clusters are flowing too! Plus, if we are in a black hole, it does make it more feasible there are more universes within black holes?

I get what you and others have said about the event horizon (EH) and the inability to communicate across the EH. how about this thought experiment, As one, a person, drone or robot, falls into the black hole past the EH, suppose they are followed by transceivers one of which stays at the edge of the event horizon. could the one that falls into the black hole communicate, stage by stage, to the transceiver that is just at the EH which can then communicate, however slowly, outside of the EH? might be a twisted idea but maybe???

Then you have failed to understand the meaning of Event Horizon - which is the absolute boundary that nothing can ever escape out from the EH, not even light or any signal. No matter how close you position 2 transmitters (1 outside 1 inside), once 1 of it falls inside the EH, communication between the 2 is lost forever.

Thoroughly enjoyed it, but I have one question. I'm curious how we're going to build this lunar collider without extraction, exploitation and profit? To build the LHC consumed enormous treasure, not to mention tonnes and tonnes of materials and energy. These resources were only available because the economy was strong enough to support it.

This way of looking at black holes is very interesting. Seems to me we always imagine BH like regions of space with something at the center. But the universe isn't supposed to have a center. So if there's an universe inside a BH, we cannot think of the interior of a BH as a finite region of space. Also quick question: if space-time flows inside high gravity regions as in a sink, is this space-time "lost"? Does it flows "from" somewhere? Other question: Mr Beacham says that with the passing of time, new distant things will enter the sphere of our observable universe. I thought it would be the contrary, that because of the expansion distant objects are getting away ever faster, and will after some time be lost to our view. Is that wrong then ?

I figured this out years ago when they started talking about them being at the centre of galaxies. It's obvious our universe is just a black hole inside another universe and so on for eternity. It will explain dark matter too when they study what happens to matter once it enters black hole.

I liked the talk. Very informative and engaging. What I cannot understand is how a smart person like James can believe in a non-scientific concept like anthropogenic climate change. I ask him, where is the smoking gun evidence? All we have is some simulations that are woefully inadequate in predicting climate behaviour.

The lecture was very interesting and he delivered with such passion but what impressed me is his last few words of this session about the human kind, if we want the space travel and everything, first we want humans to behave as a society looking out for one another or else forget Interstellar travel humans would barely be able to walk the moon with such evil and egoistic minds. His lecture on the black hole being a containment of another universe just blows my mind, it seems so amazing though only God knows best. But I really appreciate this, thanks Prof., may Allah bless you.

So, if we assume the density of mass that the universe is expanding into (the unknown stuff outside the universe) is equal to the density of stuff in our observable universe (meaning we have an estimate for both the mass and size, or volume, of the universe), does that increase in mass within a calculable change in "event horizon" radius of the observable universe come close to the rate of expansion that we calculate for the universe? This would potentially validate the notion that our observable universe is inside a black hole.
