Can we keep this man alive for another 50 years please. at least
Certainly under appreciated by the masses.
@@M.-.D Not anymore now he has won a Nobel Prize :)
miglator1 it was such fantastic news. Crazy my comment was just a day before the announcement.
God deside who live not humans 👍🏻
Usman Rajput I will remember this every time a young, innocent child dies.
People keep stating how smart he is, and rightly so, but can we for a moment appreciate how INSANLEY creative he is. His imagination just has no limits and he didn't lose a shred of it at old age...
Wholeheartedly agree, Einstein once said “Logic gets you from A to B but imagination encircles the world”, and this mans brilliant mind epitomizes this statement.
The mind possibly needs challenge and exercise to remain fully active ? I hope that our civilisation eventually appreciates that and creates equality of challenge to enrich us all more than the feeble ones so far on offer !
Imagination without observation is fantasy and not science!
I am thinking how crazy and logical his idea is! .........
I’ve got the same ideas about the universe when I was 20. And no one would say that I am insanely creative.
So incredible to see Professor Penrose win the Nobel Prize.
One of the greatest minds.
Yes especially when you dont know stuff. How much did he extracted from alfreds heritage.
This proves that there is such a thing as a gullible public and there's a sucker born every minute!
I do not find incredible that he won the prize.
Having followed to topic for many years, I must sat that, Sir Roger is a delight to listen to. We get such arrogance from Brian Green, Leonard Susskind, and worst of all, Lawrence Krauss. They hide the fact that they don't know a damn thing behind their titles, degrees, and reeking egotism; but Sir Roger presents with such humility, joy, and clarity that it allows the student to really connect with his teaching. Thank you for this great interview.
Let me guess, you didn't understand a single concept from the interview.
@@fishoutofmind4943 Why do you make that ignorant assumption? Are you just an asshole all the time?
Oh man it relieves me to see other people share the same thoughts that I've had. Penrose has intellectually achieved far more than the men you mentioned and he has done so without an ounce of arrogance. I can't even watch one of the men you mentioned talk for a few seconds without cringing at the level of egotism.
I’m sorry but Lenard suskind helped create string theory
Vendicar Kahn It’s not though and is one of the most excepted theories for understanding quantum gravity
This is one of the greatest mathematical genius. Wow
Because of his math or the swedish political prize?
@@ebrelus7687 Because of his math in my opinion. His Penrose tiling is pretty amazing also. :)
He us ok
Sir Roger Penrose is one of the very few people in human history to be well ahead of his time. He has absolutely incredible intuition for the physics and mathematics and, critically, has the courage to push ahead these ideas despite how counterinuitive they appear. I feel extremely lucky to be alive at this time when this great mind is pushing the frontier forward, even if his ideas cannot be confirmed (or do not become universally accepted) in our lifelimes. Thank you for this interview and the inspiration
A true hero. His patience and elegance are truly infinite!
It is not that he is still so bright, but his humble manners and so open mind that amazes me.
I love Penrose he has such a lively mind. He is one of my two favourite scientists, the other is Feynman. When they both speak you can feel your mind expanding and having a great time along the way.
Hello one year ago! I will check out Feynman.
Love Feynman, but he couldn’t quite explain ideas the common man as Penrose.
Yes and yes... Who are stranger?!
@3dgar7eandro wouldnt like to say they both feel strange to my mind lol! I guess if I had to pick ,it would be penrose.
What a pleasure to listen to someone of Professor Penrose’s statue question dogma and present deeply thoughtful alternatives.
Stature
Damn you, David, now I have a VERY creepy picture of a statue in a park talking cosmology at people as they walk past. @ Jack. Right on.
Jack Shumate - Yes indeed. I have found Roger's theories greatly stimulating throughout his career.
One of the most fascinating theories of his, that I have thought about for several years, is that the animal brain is a higher quantum activity organic processor.
This IS Professor Penrose.
And a sad thing that the older generation is the one that questions dogma while the youth goes along with it. Penrose and Freeman Dyson are good examples of always questioning even your own ideas, while the youth generally seems to go along with the fashion. It is supposed to be the other way around. But consumerism, information overload and decline in education take its tolls.
I have virtually no understanding of what this chap is saying, but I could listen to him saying it all day.
Is impossible no to live this guy! What an outstanding Physist and Mathematician
87 years old and still smarter than almost everybody else.
You don't get dumber as you age. You just stop giving a shit. How did the universe begin? Don't know, don't care. I want a sandwich.
Kind of a nonsensical statement...
@@zdcyclops1lickley190 lol. stop that. i don't give a shit about the twerp who had me on hold for 20 minutes, i do give a shit about how the universe started. and i do want a sandwich, and sex too, so there. upstart.
@@carnap355 give me a chart or this never happened. i have to admit all my neighbours are mental, but some can still walk to the shops for biccys.
Frank DiMeglio is way better.
DrCatherine Demetriades has given the below writing the thumbs up on her page. Here is an HONEST and extremely sharp physicist who can really think. She also added: "This is why we say a picture speaks a thousand words." Great. IT'S ALL CLEARLY CORRECT.
Mr. Shashi Singh (an excellent instructor of physics who is honest) has given the below writing the thumbs up. Moreover, he wrote: "Awesome !" and "Absolutely right."
Excellent !!!
It's all clearly correct.
THE TRULY SUPERIOR UNDERSTANDING OF PHYSICS/PHYSICAL EXPERIENCE:
E=mc2 is DIRECTLY AND FUNDAMENTALLY DERIVED from F=ma. Carefully consider what is THE SUN. The Sun is E=mc2. The Sun is ALSO F=ma. This explains the PERPETUAL MOTION of the Sun, AS gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GREAT !!! ACCORDINGLY, GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. (Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black.) ALL of SPACE is NECESSARILY electromagnetic/gravitational (IN BALANCE), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. This is, IN FACT, proven by F=ma AND E=mc2. (BALANCE AND completeness go hand in hand.) So, consider what is c (A POINT, A PHOTON). A PHOTON may be placed at the center of THE SUN (as A POINT, of course), as the reduction of SPACE is offset by (or BALANCED with) the SPEED OF LIGHT; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/ENERGY.
The BALANCE of being AND EXPERIENCE is essential. Dreams balance being AND EXPERIENCE. In dreams, it is you AND other than you are IN BALANCE. Indeed, there is no outsmarting the GENIUS of dreams. Dream experience is/involves true/real QUANTUM GRAVITY. MOST IMPORTANTLY, in dreams, BODILY/VISUAL EXPERIENCE is invisible AND VISIBLE IN BALANCE. (THE EYE IS THE BODY.) Dreams make thought MORE LIKE sensory experience in general, thereby improving upon memory AND UNDERSTANDING. INDEED, the ability of THOUGHT to DESCRIBE OR RECONFIGURE sensory experience is ULTIMATELY dependent upon the extent to which THOUGHT IS SIMILAR TO sensory experience. MOREOVER, it is ALSO a very great truth that THE SELF represents, FORMS, and experiences a COMPREHENSIVE approximation of experience in general by combining conscious and unconscious experience. (THOUGHTS ARE INVISIBLE.) Dream experience is possible/potential AND actual IN BALANCE. BALANCE AND completeness go hand in hand. Dream experience is always that of what is the BALANCED MIDDLE DISTANCE in/of SPACE. GREAT. Dreams combine, BALANCE, and include opposites.

What a wonderful man. This is how you explain complex themes in layman's terms.
really?
@@jlakes100 Do you think I said something controversial?
@@kenhiett5266 Actually I was being sarcastic with myself, because I have a hard time understanding his "explanations," which are well over my head, even though my first degree is in electrical engineering. I meant to question your comment "layman's." Sorry if I wasn't funny!
@@jlakes100 Oh I get it now....Haha. I couldn't figure out your angle. Just another example of how lack of tonality from text is lacking.
@@kenhiett5266 and when we argue on social media that is exactly why social media arguments blow up because we hear tonality that wasnt there .... anyhow yup totally right awesome guy that explains his theories in ways that we ordinary mortals at least have a fighting chance of understanding ...
At 89, he’s still on the ball. Love this man! I’m not a mathematician but I love listening to him and can understand the way he communicates.
This man has the most soothing voice
Sad to see him aged. I want him to be around for eternity
he is 87
He very well might be, and so could you. ;)
Could remove 10 years with a decent haircut!
@@lsbrother he is a fucking scientist, the whole idea is to have messy hair.

With all our knowledge and technology. Can't we get this man another life?
We can't even figure out how to make communism work.
If you believe in the Bible, life never ends. When you die you simply move to another place. Me I think when you die, you experience the same things as those you experienced before you were born.
Give the man a break, he's done more then most could even ever dream of dreaming of doing for science and humanity. What a wonderful person he deserves peace.
One life is enough. Others will continue his scientific work
@@zdcyclops1lickley190 it's not only in the myths of the Bible, you can try to learn about

That's one personable genius right there!
I love that we live on a universe where beautiful nature, brilliant conversation, and what sounds like a music club in the background can all exist together.
Hearing the birds and the baselines while Roger talks about the future, past and second law of thermodynamics makes me smile.
He was 7 or so and his younger brother was 5 or so and he was busy establishing a connection between a simple game of Rock Paper Scissors and logarithmic tables and free will! That’s miraculous!
Absolutely wild! Most kids learning the times tables at that age 😂
That Escher's picture used to be painted on the walls of our old post office here in my Dutch home town!
I remember staring at t as a kid to and also wondering about concepts of infinity while I was waiting in line with my mom.
That is actually one of the most elegant ideas I've heard in a long time.
Post COVID-19, any one realising how incredibly thankful we may be to have him still in our midst?
Communication changed so much in his and our lifetime.
Post Covid? 150,000 die each day and we're over 1,000,000 deaths since January worldwide. We're not over it yet, I hope this man stays safe
Sir Roger Penrose has a remarkably gift for rendering elegant theories of physics without a blackboard. As a general reader with introductory physics background I got the drift of his explanation. Enough to stimulate my curiosity to look into these subjects further. I also credit the interviewer’s skillful questioning. It seems intuitive now. A memorable experience !
The theory btw is called "Conformal Cyclic Cosmology" or CCC, and the book is called "Cycles of Time."
He already told us that himself. but thank you I suppose....
@@Psi001 - I'm just advertising for him, loved the theory, every ad helps.
What makes this man special to me is not his intelligence, creativity, or personality. It's his ability to speak in a coherent and interesting way. I've long held the belief that a better a person understands something, the simpler they can explain it with as little esoteric language as possible.
A lot of these professor types use so many esoteric words I feel like I have to translate before I can even begin to actually comprehend what that are trying to say.
I agree completely
7:58 “big and cold is equivalent to small and hot... when you don’t have mass around to give you a scale” / it’s a conformal geometry
14:39 “... but infinity to a thing with no mass isn’t all that long ...” (time stands still for photons / at the speed of light)
33:16 “I guess I’m awfully stubborn... I don’t give up on these things, that’s true...”
I like how he managed to present his three “children” (Cyclical Cosmology (theory about the whole), Twistor Theory (theory about the parts), and his theory about free will (the room for the human in it)) almost unimpeded by what the actual questions were. I like his ability to turn problems into solutions: the uniformity at the boundary of the Eon suddenly becomes the solution instead of being the problem, and all he did was change the perspective / step outside the box. And though I know nothing about Twistor theory, it seems he has done a similar thing: found a way to change the picture just by reformulation into another language (where “events” no longer are points in spacetime in the sense of building blocks, but become events in the literal sense (interactions of the actual building blocks of the theory); spacetime itself is emergent, which is a very recent concept for most other physicists). - Indeed he is stubborn and consequent about turning physics from its head onto its feet again.
Wow! What a nice comment!
I'm no physicist or mathematician, but Roger Penrose's theories really strike me as commonsense. What a brilliant man and so humble; such a sweet and likable nature he has, too.
@MichaelKingsfordGray No, Taurus actually. :)
Thank you, I loved this and want to hear more from this great man.
Amazing! We need more of these kinds of interviews!
Listening to a giant speak, upon whose shoulders future Scientists will stand.
No. His model is false. There is no 'Gravity'. No 'T' Time either. No dark matter. No dim matter. No Big Bang. All false.
No black holes either!!! Of whatever type.
Ashley Law ??? Are you a creationist or something?
Dobby Dazzler so Penrose is the new Newton, I gather?
@@francoisrd The 'Big Bang' is creationist. It is a magical tale based on the 12 century religious fable recast by a Belgium priest in the 20th century - All from nothing ! Absolute baby stuff. All this magimath black hole universe (and there more than 1 type of black hole - apparently ! or big bang universe all fantasy for the masses. Nature is elegant, economical never wasteful.
@@ashleylaw And there are no TH-cam comments.
Great interview, great interviewer. Thank you.
Yeah. There might be humble geniuses like him out there, but definitely rare to have calming and relaxing presence as he does.
Listening to Roger Penrose gives me so much hope, what a gem, a true humanitarian.
This man is brilliant. Fantastic video
"The Road to Reality" was such an amazingly insightful book I don't think there's a better book to read to truly understand math and physics
Long have I been troubled by the ad hoc introduction of Inflation, as well
One of the few physicists I respect. Humble and brilliant.
Delightful, profound, wonderful.
Thanks! Prof. Penrose is always interesting to listen to. As to why scientists 'hang on' to theories, pushing ahead with them regardless... I think *_all people_* do that to some degree. With scientists, it's the idea that they've got so much invested in what they're working on, & they think it's a good idea, if only *_this_* part of it can be made to behave. Someone who spent 50 years making shoes one way is not going to suddenly be receptive to someone else coming along and telling them, "Hey - that's not the way to do it!" So it's mainly psychological; a kind of mental and social inertia. Anyway, thanks again for a great interview. Rikki Tikki.
Watching once is not enough , these ideas of reality and existence are thoroughly intriguing and plausible to me !
How so?
He is the first person to draw my attention about the Philosophy or Physics .Even if I am far away from those calculations I've always been certain ,that our universe is just part of the infinite ones.Good man ,congratulations about the prize :)
On the edge of my seat anticipating his every word… True genius…
It also pleasing to see Roger in sound health and mind.
35:36 - LOL Some dude just casually skinny dipping in the background there.
Yah right. I am sure he is more interested in if the water is cold enough to drive his nuts up his nose than gravity and the big bang. As for me i am more interested in the big dong. lmfao
A naked Singularity?
Is this what you get from the video?
@@raymonddooley2623 ahhhhh❗🤗👍🏆
Singularity explodes.
Very interesting and very brilliant talk as it is usual with Roger Penrose. Many thanks for this very nice video .
On of the greatest mind of human kind of all the history of sciences. Thx for everything!
Congratulations Prof Roger Penrose on your Nobel Prize in Physics for the year 2020. 😊🙏👏👏😊👍
I am extremely fascinated by this theory. never have i been able to resolve the concept of infinity with general relativity and inflation before having it explained by Roger Penrose. Its just like when my comprehension of extended dimensions formed, except so many more cosmological facts can be explained with a compression of infinity this way. I have so many questions but im feeling that this is a step in the right direction and excited to explore the data from the planck satelite regarding these claims.
it is still infinite ....he just replaced simultaneous infinite existence of parallel universe with a sequential one
A big Mentor for me. Thank you for your Work. ♥️
Love Dr. Penrose. One of the few gifted physicists / mathematicians left.
Legend in his own right....
I really like his cyclic theory, it sounds so neat and tidy. It would be great if it eventually becomes mainstream.
B ut does it explains the first universe. How did that come about. Or is there no first universe?
@ Difficult point to answer. If this universe is dynamic and not static, any past universes before this may well have been rather different from ours and maybe originally have evolved from nothing. Does the mainstream big bang theory rule out the concept of anything happening before t = 0? How could such a event create something so massive in an instant out of nothing?
This was such a well conducted interview
One can tell Dr. Penrose can get so deep in the topics he discusses his knowledge is superb
I love Roger. Some younger people may not realise that he was such a cool guy with great hair and big mutton chop sideburns. And that’s important!
His concept of our reality is truly amazing if you actually get it TBH! 🙌
What a brilliant theory ! I love it when the penny drops , thank you so much Professor Penrose.
I saw him in a public lecture ca. 6 years ago in Germany. It was a mind-blowing lecture about the microwave background and the possibility of eternal cyclic universes. A truely inspiring mind!
Amazing interview. I really wish someone could edit out all the distracting bits. If they knew who it was, you'd be able to hear a pin drop.
cold becomes hot,
dark becomes light,
ying becomes yang,
another big bang!
Cold is a privation 😎🤟🤟🎸

and with matter comes space,
then this starts to buckle and matter slides to one place.

the space disappears,

And on and on the merry-go-round,... To what end?
Me llena de luz! Poder tomarle prestadas esas imágenes del mundo, es extático. Gracias por tanto Roger

No matter his age, his mind is as fruitful as ever, and long may it be so.
I work at Oxford.....I'm retired actually....lol.
Excellent interviewer. Well done.
Best and most sympathetic mathematical physicist of our times. A beacon for scientists today and tomorrow. An honour to share the same time frames as Sir Roger.
He is cool as hell 😄
How often do you hear "My final question will be..." with 30 minutes to go in the video?
So we’re just 14bil years from the birth of this universe.. and it will take google more years for a single black hole to “dissolve” meaning we’re at the beginning of everything .. almost as close as possible to a birth of a universe. And definitely at the real beginning of an understanding of what the hell is going on..
Underted comment 🙂
Great interview questions.
great talk. wish it was in quiet setting. and 35:40 it is very nice to see background as we listen one of the greatest minds of our time

Excellent comment. Made me resonate with laughter.
@@scorp10fl53 Yes it made my balls jiggle with glee also
Is it weird that his theory makes much more sense to me than the normal inflation theory?
Its elegance gets me excited too.
Yes
By Jove, I think he has it! Learned more about cutting edge theoretical cosmological physics in 1st 10 mins, than the last year. Thx Professer Penrose.

Finally - I was waiting for someone to confirm "infinity" as the solution for everything (small or large). There is Dr. Penrose, thank you. Thinking made it possible for him to live a great and happy life.
I understood nothing but it sounded so convincing so it must be true
One of my 'Absolute Favourite People'. And, umm, to be clear, that's Sir Roger I am talking about... not the naked guy in the background
Paper, scissors, stone at 8 years old makes up a logorythm?!?
A different level.
@@MrBollocks10 haha I know, right? Aged 8, little Roger is perfecting his algorithm...aged 8, little me is perfecting his Dalek impression
@@MrBollocks10 I think he meant using the digits in the logarithm of some random number to determine what he chose. Instead of just going with the flow of his own mind. Which is basically using a source of entropy from some external source.
Absolutely extraordinary. I only have a bachelor degree in physics but all the same, in those three years I learnt much of what comprises physics in the latter part of the 20th century. I never felt happy with inflation. Inflation just solves a problem, it does not have any solid evidence. So I agree with Prof Penrose on that topic. Also I understand him perfectly when he says that once size is effectively immeasurable (we measure size by relating things to, say, a ruler but there are no rulers) and particles have no mass then supper big is precisely the same as super small and consequently one eon merges into the "singularity" of the next. I also agree with his idea on the oddness (so often pointed out by Sean Carroll) of the very low entropy of the beginning of our own cosmos (or eon). Penrose ought to discuss his ideas with Carroll in my humble opinion. I'd love to see them discuss it. I have always felt that Penrose was an extraordinary scientist since I read "The Emperor's New Mind" and Carroll is no slouch holding, as he does, Richard Feynman's old position. It is amazing that Penrose can still be there at the forefront at the age of 87. He's a remarkable man still having a truly remarkable career. I love his videos and I take his ideas very seriously for what it's worth.
Love hearing Sir Roger Penrose speak. Thank you for this.
high as fuck rn and it makes so much sense, hopefully i remember in the morning LOL
This man is I would call it - Superscientist. He got Nobel Physics prize today, it's all.
He's a national treasure and a legitimate genius

A brilliant brilliant human being. This is the type of mentorship that schools need to implement on a global scale. More scientists, less politicians.
Penrose is a global treasure. The quintessential essence of an ‘Englishman and a gentleman’
