Sir Roger Penrose serves as a great example of what a life spent in the pursuit of knowledge and unraveling the mysteries of the Universe can do to you. This man is over 90 years of age and is still as sharp as knife. Respects to you sir🙏

I was shocked when I learned that he's 91. So he he was 89 when in 2020 he had time to work hard on the ideas buzzing in his head. Not what generally happens at that age, I don't think. Amazing.

One thing that is fascinating about Roger Penrose is that he is one of the greatest physicists of our time, meaning that he is one of the strongest proponents of the physical reality of the universe. Yet, he takes amazing risks on his reputation by taking a new position on the serial multiverse and advancing the idea of consciousness. Now, that's what I call Einsteinian conviction and courage.

The fact Penrose is still around and kicking doing these interviews is amazing.

A very informative summary of whatever he achieved. "Physics is far from finished." Gotta say, one of the best lines in this whole interview.

Most people watched Netflix and cleaned their house during Lock-Down... Penrose earns a Nobel Prize

One of the things I love most about Sir Roger is his unassuming modesty. He's like a living fossil from the pre-internet age.

"I don't believe in any religion I've seen, so in that sense I'm an atheist. However, [...] there is something going on that might resonate with a religious perspective". Very well said imo

Roger Penrose is the pre eminent theoretical cosmologist of our time. He combines clear thinking, imagination and humanity not seen since Einstein. We are fortunate to have him.

Roger Penrose is an inspiration, I hope that when I / if I reach his age, I am still as open minded and able to take such intuitive steps.

I love Sir Roger Penrose. He is the man that got me interested in physics. I listen to every interview. Amazing mind and such a humble exceptional soul

I've been lucky enough to attend one of his speeches at a conference in 2019. He's a lovely, down to earth, person, and definitely one of the smartest people alive.

I met Roger in 2012 at a conference.Was an impressive moment! Such a great scientist. He initiated the possible solution of non locality and black holes.

Sir Roger is an absolute treasure.

Roger is such an intelligent man. I hope at least 1 of his fringe ideas are taken up by the mainstream while he is still alive. Einstein 2.0 I.m.o

I know this is over my head and Sir Roger knows it's over my head, but he's very gracious to take the time to explain it all in a way I can at least relate to. I always feel so smart after listening to this man. It's hard to believe he's only won one Nobel prize!

He is an example of high intelligence knowledge culture greate scientist who highly deserves respect beeing one of the best open minded physicist of our modern time. Working so passionate beeing so busy with his subjects made his mind fresh and young for ever. What a pleasure to listen to him. Long life Sir Roger Penrose

Awesome, 91 years young and as sharp as a razorblade. It's a true pleasure to listen to Penrose

I love Roger. His knowledge and understanding is breathtaking. To me Sir Roger is one of the few scientists who truly realise and understand just how little we as human beings understand things. A lot, but not all, scientists believe the things they know are true. The really good scientists know that all our knowledge is simply an approximation to the real truth.

Remember, just because someone is an expert in one field, doesn't mean that they are an expert in a related field. Similarly just because someone has sound epistemological rigor in one area doesn't necessarily mean they're going to have the same level of epistemological rigor in other areas

iI started watching Sir Roger's videos during covid..best thing on the internet. I've learned a lot and it's fun. I especially like his drawings and when he gestures with his hands to explain something. Jeannine

Amazing thinker, scientist and philosopher. One of the greatest (if not the greatest) minds of our time. Makes me regret not having studied physics. I wish more scientists pick up his work and search deeper on the paths that he has already opened on cosmology, consciousness and philosophy of science. And what a great interview. Short, spot on, substantial and quite encouraging to search and learn. Great job!

It's always fascinating to listen to sir Roger Penrose.

I love Roger Penrose so much. Thanks for sharing the conversation and interview.

Cannot for the life of me accept that this man is 92. Far sharper than people i meet who are 60 years younger.

A luminous and unafraid mind.

I just love Roger Penrose. He is my favorite scientist of our days, and probably the smartest person who has ever lived. Some say Einstein is the smartest, Neil DeGrase Tyson says Newton was the smartest. I read several Penrose's books. And I read them so attentively, that one can assume I read each page twice. You start reading a chapter, and you don't understand why he is telling this. You finish reading the chapter, and you have the "AHA" moment, and you need to roll back 5 or 10 pages back, and remind yourself what was told previously. Or 20 pages back, and then 20 pages forth. The depth of his thoughts is beyond human limits. And I say, sir Roger Penrose is the smartest person who ever walked this Earth. And watching this interview only makes me more confident in this belief.

This is what is Upanishadic Advaita (there is no two or singularity) !...Consiousness is beyond objectification !Thanks Prof Penrose

I love listening to this man articulate his thoughts and beliefs related to all things physics.

Sir Roger Penrose definitely ahead of currant thinking.

"Consciousness must be beyond computable physics." Pretty rare for a scientist to admit this! Shows great humility and honesty to discard the untruth. A necessary condition of measurement is duality. To measure, Absolute Consciousness (What is') has to create a temporary illusion (relative consciousness) of breaking itself up into the instrument of measurement (measurement Consciousness), the object that needs to be measured (object consciousness) and the one performing the measurement (measurer consciousness). Without this illusory break-up that 'What is', is all that is left. Discarding all untruths (relative consciousness) ends all measurement.

Penrose is the sharpest and most youthful mind of this era by far. If only he realised that just as time is the clock in the subatomic real, so is energy the grid. So he is almost right with CCT. The central singularity alternates between a energy singularity leaking space and a spatial singularity leaking energy. Currently our big bang universe is the former , but will at zero energy invert to the latter. So entropy viewed over both grid settings is always constant of 1. Wit this extra insight CCT for cosmology is correct.

Privileged to have a man of the calibre of Sir Roger explaining this

Interesting interview. I tend to think that consciousness is not calculable, as Sir Roger suggested, but is an emergent phenomenon as biological systems became more complex and developed multicellular nervous systems. I expect that the reductionists can play with the standard model till the cows come home and you will not figure it out as consciousness only exists within those systems. Furthermore a completete physical, chemical, morphological and physiological description of an organism with consciousness will not tell you either as what we usually mean by the term is what it feels like to the organism that has it. Even the description of the experience of consciousness is an abstraction of the real experience not the real thing itself. Being a scientist I am of course open to experimental information that would contradict this, e.g., show that there is a quantum field of consciousness.

Sir Roger Penrose is one of greatest physicists, but at the same time so modest and unassuming, unlike some other famous physicist who claimed that we know so much about the universe that we are almost like god now.

Sir Roger, he’s been my favorite for a long time. He seemed to get along with Sabine, I would love to see them discussing things again.

Thank you to our host and Guest Sir Dr Penrose for this updated interview. Alway learn something

Clickbait title. He's mostly talking about black holes.

Please post the full - unedited interview. So very much is lost in this informational bowdlerisation. What we get is incredible !.

I never thought of this until watching this today, but he seems to inadvertently converging to the same conclusion David Hoffman is with his theory that consciousness is somehow involved in 'creating' our reality (or at least hiding reality from us). I can never quite tell if adhering to either of these ideas is some kind of self-centered narcissism or not, but it is intriguing,

With more scientists like him there would be more respect, carefulness and much more self criticism among physicists. I'm personally sick of these self-centered physicists who claim to "know it", while with every sentence they underline that they never spend any thoughts in epistemology, the nature of consciousness or philosophical idealism. His modesty is an example.

Incredible time when we have access to this kind of content

Loved the interview just wish it was longer. Thank you New Scientist and Roger.

Well, Roger, I was one of those young people who started doing physics because of your book “The emperor’s new physics”. I was studying engineering at the time and by chance listened to some guest lecture called “In search of the white hole”. This lecture turned out to be one continuous rant against you and your book, that had just appeared. The rant didn’t impress me too much. On the contrary, I went to the library, picked up your book and went on from there.

Amazing thought provoking and deep meaningful talk. I just love his integrity and honesty on what we know, and what we don't.

Consciousness is probably the greatest mystery of all. His notion of other civilisations resonates with me. I consider that during our evolutionary journey we developed many survival strategies. Not difficult to appreciate how fear and greed, in the African bush would have been very useful attributes. They are still there strong as ever. Then of course we developed our pre frontal cortex and started to engage in abstract thought. Undoubtedly the greatest survival strategy, placing our species way ahead of the rest. My concern is that, thanks to the cleverness of deductive reasoning, the unwanted effects of our inventiveness is rapidly destroying the environment which sustains us. Will we adapt? Or will the old Adams of fear and greed overpower reason and rationality? Which brings us back to Penrose's supposition that there have been other societies.They must have arrived at a similar juncture. Each with the means to self destruct on a global scale. I would like to be more hopeful - but I am fearful.

Right or wrong (and he has already been right several times) - science needs daring visionaries like Sir Roger, visionaries with a solid foundation in mathematics.

Honestly this more than anything I’ve ever heard explains the compulsion we have to figure out the world and share what we’ve figured it to people

Fantastic interview. A privilege to be able to watch it. Thanks.

I read most of his books. He is an exception to other scientists because he respects the general public and believes the have the capability to understand all math required to comprehend complex physical theories.

That short discussion was brilliant!

I love this man... a true wise elder who leads us to the edge of knowledge and invites us beyond.

What an interesting guy! Great to hear from him.

I love his work with Stuart Hammeroff, it's so interesting and I love how it upsets people who think they understand whats going on with consciousness.

I was the first one who conceived the idea of communication channel between eons ("Encoding information across eons", unpublished). I published my Arthur Clark-like paper abstract here on YT. Also, I conceived some more fundamental ideas of improving CCC, basically removing "t" from equations and replacing it with "flow of entropy".

Thank you mister Penrose I am a regular person but your explanations are so good that I can “ understand “ a little. The UNIVERSE bless you always.

What a wonderful interview! Thankyou.

my problem with consciousness requiring anything more than a quadrillion synapses is the qualities we are seeing come out of machine learning research, obviously they are not a one to one comparison, clearly the capabilities of the non-quantum structures similar to those in the brain are evident, I don't think it's unreasonable to assume that an intelligence of such a scale explains the phenomena of consciousness

One of the last great scientists

Surely a candidate for greatest Briton ever. The possibilities he speaks of are seductive. When the world is more entrenched, and single minded, he’s running rings round everyone, entertaining possibilities others fear to tread.

Could be that the consciousness has something to do with some sort of quantum phenomena. Perhaps there is in fact some sort of 'quantum field' that permeates the reality that we utilize unconsciously and it manifests as thoughts or ideas. Or maybe our brains are somehow the anchor that 'captures' or 'resonates' this 'field' and in that scope resides our consciousness. Same of course goes for every living animal. The no-hiding theorem states that if information is lost from a system via decoherence, then it moves to the subspace of the environment and it cannot remain in the correlation between the system and the environment. If there is afterlife I'd prefer it to be one where my consciousness is free to travel to any place in the universe or 'sea' of universes after death, or another plane of existence all together. Observable universe is big place, unobservable even bigger. I'd like to think we all become part of some greater whole when we leave this state of existence. I wish Mr. Penrose long life and clear mind to the end. Absolutely brilliant man and great science communicator.

Impressive, inspirational person. We need more like him.

I've heard her take on this subject before, but it's always a pleasure to hear him again.

I’m starting to think of our expansion of our understanding or knowledge like training ai. The more “programs” we train on, the more we can progress. If we only study what we currently know we will reach a cap and so it is necessary for many theories to be created and examined, whether those theories are correct or not. Walking the wrong path can yield universal truths and develop new thought patterns toward what we currently think we know. Keep up the good work gentleman because if we all follow the same path we will miss many things along the way.

500 years from now people will be laughing about what we thought we knew, just like we laugh at what people thought 500 years ago !

when I think, I feel that my thinking voice is inside my head, but I also feel that there is something controlling that voice outside my body as if my true self is not just my body but my enviroment, my knowledge and my memory, in other words, my connection to my past, my presence and the projection of my possible future. I feel that I live in the now but my true self seems to live in a timeless state that is as big or small as I allow. I wonder if my consciousness is really just myself or everything. I feel like I am free will floating in a sea of endless possibilities.

Dear Sir Roger, I hope this finds you well. I have a few questions. Is our universe one half of an ER bridge at the centre of which is the next eon? Is our CMB the (event) horzon at the beginning of this eon in our side of a supersymetric structure? Do we observe/experience time and the exponential expansion of our universe as we travel towards a 'conformal singularity' and gravitational centre of the ER bridge, whereupon is the photonic still point prior to the beginning of the next eon? Could we observe mass dependent local variance (macro filament structure due to spagettification) in the over arching exponential expansion within the ERB, while still heading toward conformity at it's epicentre and the beginning of a new eon? Are we already in one side of the conjoined wormhole or ERB? Many thanks should you give this any of your valuable time, Yours in faith with hope for understanding,

Language is entangling; we are now entangled!

While he is taking risks, he's outside of his domain of expertise in saying things like consciousness is localizeable in a cellular components, or modules of the brain. Consciousness is more likely distributed across connections an irreducible to boolean operations - more like an emergent property of astounding complexity across electrochemical mechanisms we simply cannot fathom, yet.

Great interview. I like when he suggests that maybe one of the purposes of Physics is to transmit our civilization knowledge to the following aeon..

Probably the most intelligent and most open minded man in the world.

For myself I don’t see anything mysterious about consciousness. I see consciousness as a growing awareness of who you are that begins when you are born and increases through life. The awareness is composed of knowledge physically stored in the brain. Apologies to Sir Roger.

Excellent. Good interview! Thank you.

I honestly find shocking and baffling that the scientific community hasn't picked up on CCC. It's one of the most coherent, elegant, mathematically sound and straight through cosmology theories I've heard, plus it has actual experimental evidence! No need to invoke unprovable stuff (I'm looking at you multiverse) or shoehorn ad-hoc hypothesis (I'm looking at you inflation). It's just brilliant.

A great conversation with the genius Roger Penrose.

Low entropy at the big bang and at the end of eternal expansion (when the Higgs field is switched off) is the essence of Penrose's world view, supporting the theory of reversibility of irreversibility of the 2nd law of thermodynamics.

Love listening to him talk, explains it all so well just wish I could understand it all.

Living legend Sir Roger Penrose is so genius but humble... one the greatest mind of our generation ❤️👑 Awesome theory about quantum and consciousness 💫

How I love that one of the most brilliant men on the planet can actually say that he 'does not know'! Would be so amazing if we could hear a discussion on Consciousness between Roger Penrose, Richard Dawkins and Sam Harris. Couldn't respect Sir Penrose more 👏🏽

10:05 Penrose says he's not religious, but there's something going on (i.e within him) that resonates with it.

I think that a complete unified theory of gravity will explain how the building blocks of everything we see today should reveal itself soon, particularly with what the James Webb program could show. If there is an eternal spread of darkness then the building blocks would have evolved from the darkness. I also think our current models need revision. Conformal cyclic cosmology is very very wildly centred around the fact that there is a region so small that previously it had contracted into this state. We may also need a theory for repulsive gravity. It's becoming ever more mysterious the further we look back. I will be more interested in how we all got it wrong. That will eventually become the most profound set of events now and into the future

He said _"you should be worried about science"_ and _"consciousness is beyond computation"_ and _"the presence of consciousness is not an accident in certain sense"_ and _"I'm not all that optimistic that were going to go on for a huge length of time"_ and _"maybe other civilisations will be more sensible than us.. settle down"_ and _"send signals ... tat tat tat you stupid idiots ... that's what we are doing"_ and _"I would say there's something going on that might resonate with a religious perspective"_ *The very highly improbable is all that is left after you eliminate the impossible..*

The idea of signals from previous universe was discussed in sci-fi novel His Master's Voice by Stanisław Lem published in 1968. It's interesting that the similar idea although in a different form (not a signal but wandering planet covered by 'layers of memory' from previous universe) is present in The Goblin Reservation by Clifford D. Simak also published in 1968.

Remarkable man. In terms of consciousness and Quantum mechanics. I can attest to this because I've had Out of Body Experiences and I was somehow able to separate from my physical body. I was able to perceive and experience things whilst unconscious. I could see things more vividly and I even met deceased family members so I absolutely believe consciousness is MORE than brain.

Right! Penrose gives a booster so gentle, even that am far not able to compliment but I love & remind I full time about Dear Edward wilson into a good & beautiful thought. Am filled with certain regret wish I did that & this, maybe that have prevent, so sad of i. But it is so lifely I got you by your living, sincerely this is a great thing for I & I deeply appreciate this your interview very well and help me swell heart lowered from regrets.

LEVELS OF CONSCIOUSNESS? * (Lowest Level): Just energy in a coherent format interacting with itself. (Unconsciously). (Unless some scientific experiment can show that energy in and of itself has consciousness. And what good would even consciousness be if it did not have any memories and thoughts [which would take extra 'circuitry']?). * Some sort of feedback mechanism, but with no real consciousness, memories or thoughts. * Some sort of 'memory' established, but still no consciousness to consciously interact with that memory. Just basically like stored preprograms that get activated at certain times. * Low level unconscious activity occurs that can interact with those stored memories. * Higher level consciousness activity occurs, while still having unconscious activity, that interacts with those stored memories with 'thoughts'. (Where we are currently at). (Basically, consciousness is an emergent property in this existence). Or so it would currently seem. Subject to revision as new information might dictate.

I a;ways enjoy listening to Dr Penrose, same with Sabine, but really - this kind of speculation isn't science. It's much like arguing about how many angels can dance on the head of a pin. I'm now 70 and have been an amateur astronomer since my late teens. I've given up on any physicists/cosmologists figuring out where it all came from. Not an invisible man in the sky, definitely, but their theories aren't much different.

About some of his final words: we don’t know what will prevail , power or wisdom

does anybody know the "4 mainstream views of what consciousness is" that Prof. Penrose mentions at 9:10? thanks

Following Rene Descartes meditation Category 1: Minds I exist and I am a mind. Therefore Minds exist. Category 2: Matter I have feelings. These feelings originate from sensors in what I call my body. The sensors are receptive to stimulation from events created from within my body and from events created from outside my body. The stuff that bring about these events I shall categorise as matter. Thus my body is also made of matter. Therefore Matter exists. Category 3: Space My body needs space and matter in general needs space. Matter can exist only in space. Therefore space must exist. Category 4: Time My body needs time to change and matter in general needs time for change. Matter can change only in time. Therefore time must exist. From the above observation I conclude that these 4 categories permeate each other and exist equally with none more abstract or less abstract than another. Now to the question of the origin of these categories Could it be that any one or more of these categories can be made from any one or more of the remaining categories? Could these categories transform from one to another? Matter needs space and time for its existence, therefore without space and time matter will not exist as such matter could not have been the origin of space and time. From physics it has been observed that space and time can give rise to matter spontaneously. As such matter maybe a result of a localised change to space and time. So then could space and time be the origin of everything else? Again from the theory of the Big Bang all space, time and matter originated from this singular event. Therefore space and time could not alone have brought about the other categories. Since the big bang was an event, could it be that all things are made from events? Where there is space, time and matter there is always an event. There can be no space , time or matter without events. In an instant all of space and the matter is nothing more or nothing less than a set of events. So then space, time and matter is one and the same as a set of simultaneous events from one instant to the next. From this observation the 4 categories can be reduced to 2 categories Category 1 : Minds Category 2 : Events Now then can minds exist without events. We know that simultaneous events give rise to feeling in minds. We know from special relativity simultaneous events cannot give rise to anything physical or material. Therefore feelings cannot be physical or material. Now as feelings are a part of minds we must conclude minds are not physical. Now can the mind exist without feelings OR does feelings create the mind, that is one and the same as the mind? If feeling create the mind then as feelings are created by events then space, time and matter which we have concluded is the same as events, must also have feeling and thus be one and the same as a mind. Thus we would need to conclude a rock has a mind or is part of a mind to the same extent that my brain is a mind or is part of a mind. This conclusion is not palatable as such let’s consider the OTHER alternative Now if a mind can exist without feeling then we also know that the mind can create events. (e.g throw a rock, move a finger) So then given that the mind can create events then the big bang (The Event) could have originated from The Mind in order to evoke feelings in other minds. These other minds may have also been created by The Mind. philpapers.org/rec/DESCAS philpapers.org/rec/DESETD

What would it look like to look back after being shot out of a polar ejection from a massive celestial body? Possible cmb explanation… could explain cosmic expansion and our horizon problem?

Penrose: it looks like there’s some overlap between quantum physics and general anesthetics. Interviewer: moving on…

Very interesting. Ty for being a great interviewer as well..

The video has a disturbingly huge number of editing cuts. Is there un/less-cut presumably longer version of the same interview available?

We are here. There is consciousness. The two mysteries go together. I find it funny that anyone could think that one of those mysteries is explainable and the other is not.

👈Here's the big bang! Beyond the measure of any subdivided awareness that has no choice but to identify as the rotting flesh, "they" cyclically animate!!!

Good interviewer. Sir Roger is always fascinating.

The interviewer did really great job and asked great questions rather than going for some stupid shit. More knowledge and accurate answer in short time. Shoutout to him for asking right questions to such a great mind like Sit Penrose

perfect way to start the day, i havnt slept but thats besides the point

There are physicists where the Nobel adds to their reputation and physicists where their reputation adds to that of the Nobel. Penrose is in the later category.
