That the universe began seems astonishing. What brought it about? What forces were involved? How did the laws of nature generate the vast expanse of billions of galaxies of billions of stars and planets in the structures that we see today? What new physics was involved? What more must we learn?

Our sincere congratulations to Sir Roger Penrose for winning the 2020 Nobel Prize in Physics! Well deserved!
Yes!! Very cool
I was wondering some quantum discussions. But, very classical approach to answering the questions. Overall, great insights.
@dontzenyourselfout ?
I was able to reconfirm how good your selection is! More Nobel laureates must come out of this show!
The theory of black holes is a mathematical theory and not a scientific theory. The mathematical theory of black holes looks pretty, and perhaps Dr. Penrose has earned the Nobel price for the sophisticated mathematics of the mathematical theory. But the theory does not have any experimental/observational proof. And the scientific method requires experimental/observational proof to verify any hypothesis/theory. According to the theory of black holes, black holes cannot be observed directly. What you see in books and magazines, TV and internet - those are computer simulations and not real black holes. The indirect evidence of the existence of black holes comes from the accretion disks surrounding the alleged black holes. But other objects can be extremely compact, something like quark stars, for example, to create accretion disks.
Which brings us to another huge flaw of the theory of black holes - the assumption that at certain conditions (like those inside a massive collapsing star) nothing can stand against gravitational contraction. This tremendous assumption is made without experimental/observational proof. Therefore, it denies the scientific method. We know that when stars collapse, degenerate pressure of electrons or neutrons stops the gravitational collapse at some point. depending on the mass of the stars. We also know from experiments that when experiments attempt to squeeze quarks too tightly, they exhibit asymptotic freedom that makes further gravitational collapse into a black hole unlikely - the mathematical theory of black holes does not take these experimental facts into consideration at all.
Furthermore, if you studied the general relativity theory, you have to know that according to the equations of the General relativity theory, the collapse of a star into a black hole looks differently depending where an observer is. If the observer is very close to the collapsing star, then the collapse is extremely quick. However, for distant observers, the time of the collapse stretches to infinity. Gravitational collapse time dilation = If a black hole is formed by gravitational collapse, then to an outside observer the relativistic time dilation of the event means that it reaches its Schwarzchild limit (and becomes an actual black hole) after an infinite amount of time.
Which means that a distant observer would have to wait for eternity to see how the collapsing star finally becomes a black hole. If the equations correct, than we, distant observers, cannot observe black holes and from our point of view those stars in the process of collapse into alleged black holes remain to be observed by us as collapsing stars and not black holes.
That is, the theory of black holes tells us that from the point of view of a collapsing star, it has already collapsed and formed a black hole, and from the point of view of external observers, the star has not yet collapsed to form a black hole. Hence, the black hole exists and it does not exist at the same time. But they show us computer-enhanced simulations of black holes and assure us that the black holes are "readily observed." And for the "black hole exists" part, please check again the first part of my comment- there is no observational/experimental proof that the collapse of a neutron star into a black hole is unstoppable.
What a humble and relatable genius Penrose is, love listen to him.
i bet you pretend to understand that crap and btw he is not humble enough to say he hasn't a clue lol
i've heard better in cat fights
if that theory is the defenition of genius then everybody is basically a genius since we all can come up with a theory based on absolutely nothing.

Penrose is on another level. Great to see an interviewer, who himself is an intellectual, just letting him roll. He will be recognised as a 20th century great both in Maths and Physics.
That's crazy, man. But, have you ever done dmt?
9:53 The sheer amount of energy required to verbalise such abstract concepts actually caused books to start falling out of their shelves behind the interviewer. The small inflection of happiness across Penrose's face is as a result of a bet he made decades earlier when an identical thing occurred while explaining quantum dynamics to a classmate. The classmate said that if he could do that again, he'd pay for him to have a lapdance.

@@rosros2795 There really ARE slots for everything in creation, aren't there? I'd never heard of this bloke, but have lived a long and volatile life in line with his principles. I put it down to the gift of a very high IQ and a memory that never forgot anything. (learned to play chess in a couple of hours and was playing in the state team a few weeks later. ) Also learned Shakespearean plays verbatim after two or three readings (to argue AGAINST the value of Shakespeare!) and used to explain the connection between the two: had a sense of the inherent mathematics of chess being evident in Shakespeare's work, and the philosophy of Shakespeare being clearly evident in chess. I always just assumed it was the job of the brain to make those sorts of connections so's the whole 'creation' could be sensed as a whole. But unfortunately my dog's brain doesn't work like that!
@@dabbbles I was just kidding man...
@@rosros2795 That's ok. Just that I'd never heard of Feynman (despite being fairly widely read over many years), so I checked him out on google and immediately recognised myself in a way I never had before. For example, I often ask for definition of an issue or a word/concept because it ties all the other bits together into a kind of mesh that stores in my brain as sort of a picture. These days you might say 'the way hard-drive works' Quite uncanny! Cheers

@@WayneLynch69 it's not science if we take the espoused definition of science, which is essentially identical to rigor, but it is perfectly fine science as it's actually practiced, which is as a religion.
I just love how Sir Roger Penrose explains a concept so difficult to grasp as a Universe before the big Bang where "time" in a sense doesn't existed or passed as we are used to experience in our universe, in a way that even people that don't have a physics background can understand. What a remarkable man 😁👌👌.
This is actually AMAZING. Instead of a cold death with no mass or reason for time, the Universe becomes reorganized through cosmic radiation.
I love it when Roger Penrose says "you see" he genuinely wants us to see as he does.
Well "you see" this video started with a blur (literally), then it became crystal clear. ;D
You have, and *can* have, no idea what he " sees", any more than you can experience what another experiences
Do you want others to "see" as you do, and if so why?
Yeah. I'm sure he is (or was -- IDK if he still teaches) one helluva good teacher. If more educators in modern times were as sincere in their efforts as is Dr. Penrose, we (the USA) almost certainly would not be in the current pickle in which we find ourselves with regards to the abysmal state of our population's "education".
[Begin ranting in...3...2...1...]
You were warned...lol
You know, the one where over half of America's high school graduates were unable to find the UNITED FREAKING STATES OF AMERICA on a globe...and That was over twenty years ago.
Now, all of those "baby Einsteins" are so-called "adults" who keep themselves busy by convincing themselves, each other, and any other dull minds they can reach, that the earth is either flat, hollow, or both, and the moon is hollow, and etc., etc.
Yessir, we're just BEGGING for another group to take the lead in world affairs, which won't end well for us, at least not if you prefer English (or any other Romantic language) over Cantonese. Or, maybe it's just the freedom to be or to do...Anything of Your choice, really, that appeals to you, rather than living where you're told to live, working where you're told to work, gaining access to a very, VERY short list of government approved and government edited programming over the airwaves, and ditto the interwebs.
Yeah, the USA is, unquestionably, filling itself with Eloi, ripe for the picking.
We are voluntarily expediting the wholesale slaughter of our bodies, our minds, our freedoms, and our property, to name just a few of the things we will lose before all is said and done, should we continue to fail our youth (and ourselves) in education, as we have been doing for several decades now.
(SNS for the rant...lol. I just hope that maybe...MAYBE...if more people who HAVEN'T grown old, grown filthy rich, and permanently affixed themselves as a Neverending Part of our dysfunctional Political System [I'm looking at YOU, Congressmen and -women (and members of the Executive Branch, of course) who have been screwing...uhhh, Serving...I meant SERVING!...the People of our great nation for longer than I've been alive -- you g*ddamned jackals...you power hungry crooked SOBs!]...
...MAYBE, if we make enough noise about this problem then it might get fixed. But I doubt it, because that would require several attributes which are all in short supply in this country these days. I'm talking about things like values that are based on ethics rather than on a "Me! Me! Me!" mentality. I'm talking about working for what you have. And I'm also talking about The Big One -- Personal Accountability, which has become more or less nonexistent nowadays thanks to an increasingly coarse media which glorifies murdering, raping, stealing, cheating on your spouse, stealing from anyone and everyone you can, being lazy, believing that you're some kind of "badass gangsta!" (as if That is somehow a worthy and valuable goal...), and on and on and on...like this rant!

There is nothing like listening to somebody who knows what they are talking about, they have the ability to explain it to people like me and use analogies and the like to allow me to visualise what it a very difficult theory etc. In addition they don't get lost and confused when asked questions during their explanation, they just respond to the question and go back on track and that I suggest is because what they are talking about is very clear in their mind and hence it is easy for them to talk about it
I follow and understood the concept and it’s beautiful in its simplicity. I don’t follow the math, though.
I can listen to Sir Roger talk all day long. He’s so humble and seems so grandfatherly.
With all the crap on TH-cam, it’s people like this that help balance it out.

Combined with Alan Watts wisdom, you have it all!
Roger in all of his glory has just as much to tell us about our universe as the Bible does. Keep reaching
_ Possibly; however, it is still just theory _ scientific opinion _ part of the "dream" of life.
_ Some people buy it over religious theories
_ Both are still part of the "dream" of life.
_ The intellect is incapable of finding out beyond the finite capabilities of mind.
_ As long as mind depended on for answers, the "dream" of life continues.
For a guy close to 90, Roger looks amazing and has as sharp a mind as ever. Also a total professional: note how he seamlessly repeats himself after the interruption at 09:55 to provide an opportunity to do an edit at that point.
This was definitely some years ago, 12-20 years I'd guess. His is visibly much older than this now. Personally, I like his voice now as opposed to younger days such as this.
Definitely. No doubt an amazing man. A well deserved accolade.
He never stop learning. Researching. Pursuing for new discoveries. When you don't give up, the chase keeps you young.
Exactly! That was my impression listening to him answering questions at such an advanced age! He looks and sounds unbelievably young! God bless him even more!
Not only that, but he does not have the arrogance of some scientists
While I know I didn’t understand a lot I still found it fascinating and engaging. And I did take away the key idea that the universe is “constantly” flip flopping between being infinitely small and then infinitely big. Like scaling an image you can drag it to nothing and if you keep dragging it starts to expand but is now a mirror image of itself. I guess all I’m say is Thank you for making me think
I love Penrose, he's always been a fav of mine and I've read several his books as well which were amazing. Legend. This chat here is super engaging and entertaining.

I've heard or read about Roger Penrose and his work countless times over the years, but I honestly think this is the first time I've ever seen him on screen. He seems to be an amazingly good communicator so I don't know why we don't see more of him. Brilliant man.

I believe the societal concept of "Individualism" will be studied longer after I'm gone from this place and the effects it had on the people resent today. I am 25 years old though so I do hope I get to read and understand it before I go!
@@GreaseMonkey097 : Perhaps? I think also his origins were an influence. Individualism, in its nowadays classically accepted definition or form, is a construct more at home in US Society as a requisite of "pursuing the dream" towards the amassing of money and what it can bring, this necessitating a significant degree self centeredness and ruthlessness rather then just a degree of the same. Obviously this is a general observation and not absolute.
If you compare Sir Roger with Paul Dirac, Alan Turing and Stephen Hawking etc., they all worked with a team of others in order to have others to bounce their ideas off and were all very modest individuals. I think working in a vacuum is the more difficult way to make progress, as all that does is confirm your own brilliance.
@@stuartmccall5474 I completely agree! The future of the Science's should continue to be the collaborative effort of the intelligent. It's the only way we have progressed this far to begin with. Looking forward I do not believe Individualism, as a molding affect on society or simply just a way of Life, will impact the Science's that much. Maybe that is the beauty of culture though. The work is done as backdrop noise by the people who cared enough to do it.

What even is a noble prize? I mean REALLY what is it? It is an honor for humans to get assigned by…? Other humans. Other humans decide whether another human is worthy of it. Not to downplay achievements but in the scale of the universe even an atheist agrees that it values to nothing. Even an atheist agrees one human has no right to judge another human. Especially since atheists believe there is no true moral law.
And what even is a physicist? Even more what is the art of science? It’s the pursuit of knowledge of creation that we can’t fully understand. We can abstractly understand a lot but ultimately it always leads to a dead end.
My point: These nominations you’ve assigned him ultimately amount to nothing so why are you insulting this other person for making a statement when ultimately both people are equal in terms of their understanding about the questions of the beginning of the universe? Yes this man is more qualified in physical science but when it comes to the beginning of the universe… this topic is (and always will be) unable to prove itself without some form of faith. Both Atheists and Christians base their beliefs about the beginning of the universe on faith. Although your final statement may be correct…(probably not for this person) why direct it on this person anyway?
This concept is absolutely amazing. I love the idea of infinity being like a place that you never get to, until you realize you are already there, and things have already changed.
That seems like the purest nature of what infinity could be.

I love how he always talks with glee and enthusiasm whenever he's communicating. It's almost like watching a child discover the world for the first time but with vastly more complex ideas
This is a great video about how theoretical physicists hypothesise about the Universe, getting help from mathematicians to identify the mathematics needed to express these ideas, and come up with a theory that experimental physycists and astrophysicists can use to make observations to verify the theories. We're very fortunate to have an intellectually honest theorist like Roger Penrose to explain these ideas without any pretence that they are nothing more than ideas at this stage, whereas some scientists like to promote their ideas in the media, giving the rest of us the impression that their hypotheses are accepted by the scientific community when in fact they are simply promoting them.

@@vhawk1951kl of course I am interested in all of these types of discussions! I love how these abstract ideas become concrete realities as scientific exploration continues and answers are found.
perhaps like trying to catch or escape from, your shadow?
Thank you for finding the words... so regular people (like me) can have a glimpse on such deep, beautiful and complex theme. I’m amazed!
his is the youthful face of engagement & joyful curiosity.
14:21 I love how roger shifts back with wide eyes when the interviewer shifts forward, he's like "this dude's coming at me" and I mean roger isn't a young man here so I think right to be a little concerned becuase even if the probability of the dude actually coming at him is very low the consequences of not protecting himself are extremely dire
A unique talent to explain math and physics for the layman to understand. He is a very good speaker.
Many congratulations to Sir Roger Penrose for his long lived and brilliant career, working with Stephen Hawking and many others. His copious Mathematical Works have enriched the World over the last 70 years.
Thanks to R.L. Kuhn for not interupting Roger and allowing him to jabber on to complete his ideas, many interveiwers are constantly inserting themselves and become a distraction
Thank you for attempting to explain this to all of us "lay persons" who do not fully comprehend the world of Physics...
The thing I appreciate most about this theory is its simplicity: it doesn't require the invention of new types of yet unknown energy or quantum fields (the way most new cosmic theories seem to).
Dear CTT, thank you for your effort to bring in such a distinguished guest as Dr. Penrose. Also thank you for taking advantage of his wisdom on such an interesting and fun topic. Your channel and its contents are a precious contribution to public science education that helps us humans to become better species. Warm regards from a subscriber.
YES THE gorgon speaks.... BUT WILL SHATNER have mercy
Topic is sensationally beautiful & most demanding . It is touched , which is highly rewarding . Prof Dr CCBISWAS .
If only someone would ask, or would have asked the Penrose fellow exactly what he seeks to convey by " the universe", I guarantee you he would not be able to tell you without waffling and you_knowing, or as is said beating about the bush.
Emphasis on fun, because that is what it is!!!!!
"Better" in what sense and by what measure?-likeable?
"I have another idea which I'm pursuing which has a reasonable chance of being right." Awesome humility.
It is a good mental jog if nothing else, for I lack the grasp to assert an argument, or an agreement, but occasionally like to listen in. Never fear to walk the halls of the mountain king regardless of how small you may be.
First of all: The spoken English alone is a symphony to my mind. The scale invariance idea sounds really interesting.
When Sir Roger finally built up to the possible similarities between the very remote past and the very remote future, with the exception of scale, for which there will be no meaningful measure, my jaw actually dropped. What an elegant concept! This video is also an excellent demonstration of how individual notions build on each other within and eventually between generations of scientists.
Me too .. couldn't agree more .. 'elegant concept' indeed .. :-)
Dear uptown 3636,
Thank you so much for putting it all together into a statement which perhaps will make sense to all of us out there who can now relate and reverberate more clearly with what they felt like and thought after listening to Sir Roger...
I have a doubt . during Big bang temperature is highest. And in future which sir refer here , temperature will be lowest and all photons will be in low energy state. Then how temperature will increase and initiate a new big bang in future. Can anyone help
@@jishnuraj9866 I think what he's saying is that its not the absolute temperature that's important but the relative temperature that matters. So rather than thinking of the big bang as the hottest and the distant future as the coldest its more that at the big bang temperature was uniform, meaning at maximum entropy, and in the distant future it will be uniform, equally meaning maximum entropy, and with maximum entropy comes the inability to measure time and with it measure anything else. So I think in the same way that he said that the universe would forget it's size with no way to measure it, it would also forget it's absolute temperature as there would also be no way to measure that.
@@stephen2437 I think as per second law of thermodynamics entropy is increasing with time and irreversible without outside interference. It's just a measure of vibration of particles. At the big bang temperature was high and entropy lowest .
This is the best one in the series. It seems really logical when explaining about time.
Really? What exactly do you suppose to be his syllogism?
Just wonderful. Thank you for such a great interview.
Wow, what an elegant theory. I love it; honestly and kind of floored that he came up with that, whether it be true or not.
Congratulations Sir Roger Penrose! Amazing genius with modesty to admit that this is a mathematics, and physical reality could br different.
This man has a fascinating view; and a wonderful way of expressing things
I don't think he's good at explaining what he means
This is bone chillingly honest and raw.
Phantastic that we might be able to prove it through observation

To all the fans of Sir Roger Penrose I highly recommend reading his book The Emporer's New Mind. He goes into much more depth about his theory on what preceeded the Big Bang. He also goes into detail about how algorithms work and why computer algorithms cannot mimic human thinking or consciousness even in principle. A very excellent read that will leave AI cheerleaders quite butt hurt.
Did SRP literally write.."computer algorithms cannot mimic human thinking or consciousness"? Which were his stated definitions for "thinking" and " consciousness"? Does " cannot ", mean, " at the present time ", or, " we can safely assume that this will always be the case"? I'll read his book, but has to go at the end of a long reading list. Thanks..
@Al Garnier some say that the future already exists!
Thanks for the recommendation, sounds really interesting, I'm off to read it.
Algorithms are just brute force logic, nobody seriously thinking about the next generation of AI would rely souly on them, that's not how the brain works.
I was hoping the Plank's data will be shown, but with two confirmations (99.98%) I wonder why picture of the CMB was not shown and explained.
I believe that it's easy for something to happen than nothing to happen forever.
You got a love Sir Robert Penrose what a legend
Sir Roger here is persuing his idea of Tessellation Universe! Like those tessellation drawings of MC Escher. Also knows as conformal geometry! 🙌
1 the link between frequency and time, so simple and yet so strong. 2 "the universe forgets how big it is", like "there's no need to continue this. Let's start all over". Powerful ideas.
74% of everything in this Universe is not dark matter (69% dark energy + 5% ordinary matter). 74% of the elemental mass of this Universe is hydrogen + 24% helium + 2% other.

"Energy is neither created or destroyed, only transformed/transferred in an isolated system." General relativity's singularities: black holes, white holes, Big Bang and wormholes.
‘The BIG Bang-Bit Bang‘ inflation/expansion of energy₇₄* and information into the void 13.77 billion years ago was a supermassive white hole spawned by a supermassive black hole at the heart of a galaxy in our ‘parent₇₄ universe‘. This duality combines general relativity’s singularity point₇₄s of infinite density in ‘Cosmic Egg hatchings’ of all created universes within ‘The Conglomerate‘: multiverse without random quantum fluctuation bubble universes, no parallel universes or parallel worlds, and all universes have similar physical laws. Our Universe is 1-in-2 trillion ‘self-similar offspring‘ each with alike inherited traits/‘DNA’.
“In the beginning”, the Planck density of the core of a SBH acts as a birth canal. ‘Quantum bounce SBH-SWH seed transitions‘ are ‘quantum tunneling umbilical wormholes‘ with energy-matter and data transformed/transferred, albeit scrambled and encoded. The ubiquitous cause-and-effect ‘circle of life cycle‘: birth-life-death-transformation-rebirth also explains infinite space and eternity - a necessity. Reproduction is GOD/ Nature’s plan for greatly spreading life from cells to universes.

love listening to this man because its incredibly difficult to explain such topics to the non expert like me 😂
I chuckled when Penrose said Whoop there it is 😊
For an absolute ignorant like myself this was intense, but absolutely brilliant. The clock metaphor for the time and matter correlation is strinkingly simple and jawdropping. Never before had I seen such a simple and clear way to put it. From then on the concept becomes accessible for a total ignoramous like me to being able to at least follow the rest of the conversation. Also, the way it is put also leads me to think as time as a dimension of its own due to the close relationship it holds with the very nature of space. Not a new concept for me but now I feel like I get a true reason why for it. Of course, for a physicist, what I am saying may be of the most basic intellectual incompetence, but I find it so astounashingly fascinanting that I can't hold myself from sharing my deepest respect for the minds that can trully grasp this.
There are interesting correlations between Position/Velocity, Position/Frequency, Space/Time and the Heisenberg uncertainty principle. The core math is conjugate variables. but the fact that all these things are perfect analogies of each other makes me feel like that time is just the frequency of space at some weird fundamental level.
@@brooklyna007 YEAH! Make a video explaining your idea more?
@@timflippance3040 I would love to. But I am responsible for a family and an engineering team and they are taking all my time. =)
@@timflippance3040 But I am happy to answer any questions about the above on this thread.
I'll have to listen to this a few more times before i come close to understanding any of it.
Lmsollllllll
.... If you really want to know why the uni was created ask prisoners who are doing time.
Learn basic physics
Thank you for explaining so much. I’d like to ask: Are you saying that the initial conditions were that all was energy and no form of matter, which is why time did not begin yet? Then, after some cooling, mass/matter began coalescing and gravity began along with time?
I've always wondered why physicists are so reluctant to entertain the idea of an infinite universe so it's refreshing to not only hear Roger Penroses explanation but to even be able to wrap my ignorant head around it.
A forever cyclical universe has always just made sense to me be it the big bang/big crunch of a universe where the expansion eventually slows, or the big rip of a new universe resulting in an ever increasing expansion leading to another big rip.
Glad to discover Roger Penrose! He is able to explain very complex science to lay people like me. His theory makes beautiful sense to me, and answers some important questions, such as what happened before the Big Bang. I was thinking these gravitational ripples could even contain information that could be passed to the next universe. The theory reminds me of Hindu creation concepts and some of Buddhism/ Taoism as well. Absolutely awe inspiring.
Quite a captivating idea and topic to speculate on. Time gives meaning to everything, I believe, Sir Roger Penrose wants to say here (of course, this is the extremely simplified version). This topic only needs a whole big documentary with neatly-put visual effects.
his smile while „explaining“ the mathematical tricks is saying everything about the truth
Around 12:15 on the topic of time becoming irrelevant: At what point does the concept of time start? And when would it end? What are the approaches to understand when and how that would be understood?
Sir Roger is the best of the best. Brilliance, humanness, and common sense.
What about the invisible realm? I didn't hear Sir Roger mention it at all. Did you?
means what?
Very well deserved win of Noble Prize 2020, Dr. Penrose is one the the few physicists who contemplates on "consciousness" in a proper manner.
His speculative albeit interesting views on consciousness had nothing to do with his nobel prize... His contribution to actual theoretical physics research in the form of proving and deriving the Singularity theorems is what got him the prize.
His ”theory of consciousness” isn’t actual science. It’s just playful and creative speculation by a brilliant mind.
Clearly any fool can get one of those nonsense prizes.
@@vhawk1951kl Yeah any fool with a phd in mathematical physics who has proven the singularity theorems, been an author in hundreds of some of the most notable and influential scientific research publications of the last 100 years, discovered new features like Penrose tilings, Terrel -rotation etc and changed tensor calculus forever.
Oh wait I forgot that you don’t have any training in or even the slightest clue about differential and algebraic geometry and how they relate to spacetime because you’d prefer to just act edgy in yt comments as if you should be taken seriously when in reality you never even put the work in to study the subjects let alone get a degree in physics or mathematics. But with a bit of humility and diligence you could learn these subjects like anyone else.
@@vhawk1951kl Go on then. Go and get your fool's prize.
It is fascinating that Roger Penrose is describing the mathematical How the universe began, and what might have been prior. However, no why was given as I suspected it would be. Why is a metaphysical question header. The explanation is also complicated by expressions like: the universe does not know big it is, or forgets how big it is. However, knowing and forgetting are epistemological concepts, and it is difficult to see how they might apply to a physical entity such as a universe.
One of the greatest explanation. Thank you Sir.
