- Tune in to watch the 2020 Nobel Lectures in Physics:
Black Holes, Cosmology, and Space-Time Singularities
Roger Penrose, University of Oxford, UK
A Forty Year Journey
Reinhard Genzel, Max Planck Institute for Extraterrestrial Physics, Garching, Germany and University of California, Berkeley, USA
From the Possibility to the Certainty of a Supermassive Black Hole
Andrea Ghez, University of California, Los Angeles, USA
Roger Penrose is 89 years old and still going strong. This man is truly incredible!
🎯😎👍🍻
My sentiments exactly! When I saw his name I am thinking that must be his grandson, no?
That's a blast :D
He is the Dude
He inspired me to do physics
One day I'll absolutely be there
of course you will
Not only 89, but this Duracell-bunny is still trying to break new ground. An inspiration
Prof. Penrose is a most genius physicist and a good human being.
8:21 Sir Roger PENROSE --- Lecture starts
40:11 Prof. Reinhard GENZEL -- A Forty Year Journey
1:10:12 Prof. Andrea GHEZ
PROFESSOR GHEZ!! I had her for my professor at UCLA for my undergraduate course during my major of Astrophysics! UCLA BRUINS SO PROUD OF ANDREA GHEZ!
8:21 Intro skip
Thank you! YOU ARE A LEGEND!
thanks
Why?
Congrats Roger on your nobel prize!
sir roger penrose concept of this endless aeons are very amazing
Ethan Siegel rudely ad hominem attacked him
Missing Professor Hawking but he must be very happy wherever he is
Great fan of yours,sir
And you too
Where is he now?
He is nowhere unfortunately because he no longer exists
Total hogwash; because there is a principle called quantum tunneling which will not allow the existence of a singularity.
Quantum tunneling sets a physical limits to the mass density or the radius of any sphere of matter, therefore not allowing this singularity to start forming. The mass density ρ of an object may be found by dividing its mass M by its volume V = (4/3) π R^3. The packing of the fermions will never reach the matter concentration necessary to create a singularity. His entire argument fails because he ignores this physical principle.
Ghez, probably because she has presented similar lectures to lay audiences (some of which are available on RUclips), has by far the best presentation. An excellent job describing her superb work.
Roger pitched his CCC hypothesis in his Nobel speech !!! Bravo
He does so at every opportunity. And why not, lol. It's an interesting idea.
he's a platonist. h shold do so...
Fascinating openings for young researchers - more question are raised than answered!
Thank you Noble Prize for putting this video and others up. It is appreciated by myself and humankind. May God Bless the World.
Congratulations Mr. PENROSE!
I feel the presentation, last two presenters also demonstrate gravitational back-force, of event horizon .. Black Holes, Cosmology, and Space-Time Singularities
Roger Penrose, University of Oxford, UK
I feel should have been presenting the Einstein INCH equation .. having manufactured the Newton machine, g = G Me / r^2 ( 1e -/+ Ef/Eo ) r = c to planar reaction, 3rd plane to manifestation .. accepting a lot things to immovable frame .. the Standard Model is the Periodic Table .. DNA pattern is same Einstein INCH to 1915 Child .. imaging content to infinity .. pi -/+ line = infinity to content of frame, control the elevator.
All three lectures were excellent! Thank you.
More questions than answers
More work ahead
Go for it!
Convergence (compression, contraction, gravity) is dual to divergence (expansion).
Attraction (gravity, syntropy) is dual to repulsion (anti-gravity, entropy).
Syntropy (prediction, entangled entropy) is dual to increasing entropy -- the 4th law of thermodynamics!
Teleological physics (syntropy) is dual to non-teleological physics (entropy).
Information, entropy is converted into mutual information (syntropy, entangled entropy) -- Shannon's information theory.
In communication theory the receiver of a message infers or predicts the received message into existence, hence information is based upon probability, maximized mutual information = optimized predictions, syntropy.
Apples fall to the ground because they are conserving duality.
Potential energy is dual to kinetic energy.
Gravitation is equivalent or dual to acceleration -- Einstein's happiest thought, the principle of equivalence (duality).
Energy is dual to mass -- Einstein.
Dark energy is dual to dark matter.
"Always two there are" -- Yoda.
Concepts are dual to percepts -- the mind duality of Immanuel Kant.
The intellectual mind/soul (concepts) is dual to the sensory mind/soul (percepts) -- the mind duality of Thomas Aquinas.
Mind duality is dual to matter duality (wave/particle or quantum duality).
I can never love anything more than the way Rodger Penrose says super duper.
Beautiful Minds!!! you guys are my heroes + heroine! :) :) keep inspiring :) :)
This is who you want in our government advising us. Brilliant men. He is genius
Concept of geometry is unique and lucid.
Roger Penrose, extraordinaria persona.
All the best🎉🎉
Wow, inspiring!
I love Roger Penrose
Can't wait to hear from professor Ghez :)
??? Just listen to the video.
This video made me wonder about the scale of the universe and how tiny we are in comparison but not consequence.
Congrats sir Dr roger penrose , been 89 and still working hard
His fans love him.
Why these genius people get Nobel prize after so many years of research??
But don't worry , you will get pretty sooooooon
It takes time, especially in fields as theoretical as theoretical physics
I believe you get a nobel when theoretical work predicts real world observations. Can't give the prize til we have the experiment, took this long
They are in a back- logged queue.
@@guycomments yeah it has taken this long for technology to catch up.
I think Roger was maybe around at the time of the Big Bang
Me not knowing shit about physics and space listening to this while I wash dishes at work
Related to Prof. Penrose's work is Prof. D. Christodoulou's seminal 600-page monograph "The formation of black holes in general relativity", EMS, 2009: "The subject of this work is the formation of black holes in pure general relativity, by the focusing of incoming gravitational waves. The theorems established in this monograph constitute the first foray into the long time dynamics of general relativity in the large, that is, when the initial data are no longer confined to a suitably small neighborhood of Minkowskian data. The theorems are general, no symmetry conditions on the initial data being imposed." I'm conviced that that Swedish Academy ought to take a long and hard look at this work and all related work of his while he is still alive.
Can't wait
Brilliant concept thought by Nobel lectures Roger Penrose , Reinhard Genzel and Andrea M. Ghez. Congratulations to the Nobel laureates and keep it up.
Surprisingly clear!
great work
Roger starts at 8:20
Inspirational
Roger Penrose ❤️
Wow - always nice to see Sir Roger, but all of these were *fantastic* presentations. Dr. Ghez's particularly fascinated me - I've had my eye on her work for years, and it is just awesome to see her recognized!
Lectures should be in short cut or can be continued tomorrow.
You are a true genius physicist....I feel proud that you received Nobel prize.
Different time dimensions
Question: how can a dust cover the light when it’s so far far away? @1:19:40
Alll the very best...🖤🖤🖤
Good luck 2021⭐🌷✋
Let the lectures be restricted to 3 hours max! this is too little time for important lectures! 30 min!
"If I Had More Time, I Would Have Written a Shorter Letter" Cicero ( attribution in dispute)
Well deserved! 💯
Wow!
How could you call the CCC Penrose CYCLICAL when the flow just go in one direction? same thing is for the TOROUS flow diagram and the atom diagram flow.
Because it... cycles
This CCC cosmology is regurgitated cosmology, nothing new here, other than the terminology and analogy to bathroom tiles universe.
This cyclic model was originally suggested as a oscillatory universe interpretation of the Big Bang, where the first cosmological event was the result of the collapse of a previous universe. But in this case it keeps on exploding painting a pretty symmetrical picture, the same old thing. This is not even science you can't prove this.
Aeons are cyclical...
Physics lectures aren't too bad and werent my worst. Enjoyed history more than anything else.
Genius of physics
💳 good news 2023 good time to come
NOBEL.👍❤❤
I wonder why they don't call him as Sir Roger Penrose?
Dr. Sir Roger Penrose
@@primetimedurkheim2717 Professor actually
Penrose at 8:22
Ma dream
well ,sometimes dreams come true if you want
Of course I have shortened the stories because you are talking so fast.
After denying the Nobelprice to Hawking and Bekenstein Stockholm finally got the message:
Black holes are real and research about them deserves real awards.
What is the official reason to deny Hawking?
@@zack_120 many reasons why. They mostly did this because of, finally, the famous release of a visual image of a black hole. But there’s been lots of discussion about the way in which the prize is awarded.
Hawking accomplished almost nothing.
Stars are being born around black holes! Black holes are giving birth to starts, that is why you are observing young stars orbiting around it.

Good
38:46 mic drop
i like penrose diagram
I'd like to take this moment to thank our galaxy the Milky Way, that it has allowed us to exist :D, we can be real sobZ but you make it work everyday❤
Please try to add sub title.
The real achievement.
🙏🙏🙏🙏🙏🙏🙏
The fascination about math as the method and way for getting credibility, validity, sometimes lacking physical evidence, math has the power of persuasion. I really cannot say when scientists stopped using math as a tool for describing reality, and started using math as the "rule" for any description of reality: if it cannot be expressed with a set of equations then is not scientific. Cosmologists are so worried about the "geometry" of space, because the related math gets unmanageable. Quantum Field Theory is undeniably geometric in its approach. But as long as particles are ripples on the field, wave functions, it is impossible to consider a particle occupying any quanta of space. And all that complication comes from considering mathematics as the ruler of reality. What I like the most about Roger Penrose is that he still considers math as a tool, not a source.
He's described as an "algebraic geometer"
Congratulations to Sir Roger Penrose and co.
Here
Was anyone else here obsessed with why Hubble’s constant “isn’t” (constant) when they were a kid?
Well, still waiting for direct, f not physical, evidence for the existence of BH.
go, check it empirical yourself, and don't come back...
its my dream award ❤️❤️❤️❤️.
Hmm... it’s easy
@@timc9372 lol
From the distance the stand looks like floating...
*Gravitational constant may not be so constant.* A variable G carries powerful explanatory powers.
Has it ever occurred to Andrea Ghez or any astrophysicists, that it may not be a super black hole in the center of our Milkyway. But instead be related to the gravitational constant having a different value in the center of our galaxy, thereby altering the orbital behavior of the Stars within this Central galactic zone.
.
yeah, but why would be a variable G?... i mean, what support that hypothesis?
well we have now photographed that black hole (Sagittarius A), so that seems to be the reason.
To rush a 90 year old genius into explaining shortly his lifetime work into 30 minutes feels like being forced to chug on a Masseto Magnum from 2008 with my legs up. Leave them present freely and you may summarize after, for the presentations.
Really nice presentation, but all this hinges on the existence of singularity. Unfortunately there is a principle called quantum tunneling which will not allow the existence of a singularity, because Quantum tunneling sets a physical limits to the mass density or the radius of any sphere of matter, therefore not allowing this singularity to start forming. The mass density ρ of an object may be found by dividing its mass M by its volume V = (4/3) π R^3.
I miss Professor Stephen Hawking... he should be happy wherever he rests today...
Penrose was his PhDmentor
ENERGY IS ALWAYS SINGULAR, BECAUSE ENERGY DOES NOT ACT PARTIALLY IN UNIVERSAL ACT, "BECAUSE MASS IS VERY VERY SMALL IN CONTEXT OF ENERGY THEN IT IS NEGLECTED" BY GALILEO. I WANT TO PUT MY SMALL VIEW IN THE CONTEXT OF THE THEORY THAT ENERGY WHICH IS BLACK HOLE ACTS LIKE A PENDULUM. THE THREAD OF THE PENDULUM IS THE CHANNEL OF ENERGY WHERE THIS CHANNEL LIKE TO SWIM ACROSS THE SPACE WHICH IS UNIVERSE AND TIME IS ITS MOTION. THE INITIAL POINT OF THE PENDULUM'S THREAD MUST BE ATTACHED WITH THE UNIFIED VALUE OF TIME SPACE WALL, THIS WALL, THAT MUST BE THE OTHER SIDE OF THE BLACK HOLE..!WHERE TIME AND SPACE ACT EQUALLY WITH UNIFIED ENERGY...!
6:02 I will forever say the name 'Albert Einshtine' like this from now onwards
Actually the announcer knows his German pretty good. Speaking "Stein" (which is a German word) like "Shtine" is actually more "correct" as most German words starting with "st" are generally spoken like this by the vast majority of native German speakers (e. g. "Straße" - "Shtrase", "Stern" - "Shtern"). Only a few German dialects would pronounce "Stein" in the way the English speakers are used to it ("stine").

If photons are a thing they must to have mass just like air, if photons do not have mass they are just not a thing. - even energy must to be mass.
gluons and photons which are carries of the electromagnetic and strong force U(1) X SU(3) Lie group(special unitary) are massless without a doubt. Remember, in QCD, particles are not really particles but represented by fields.
Read up on the difference between bosons and fermions to understand why photons are massless.
Eh
So this is what it takes to win the noble prize?
Easy...!!!
Giving a Nobel Prize for Black Holes makes no sense since Einstein didn’t receive a Nobel Prize for General Relativity.
I am here only for Mrs ghez
Nobel should be awarded to people who discover or invent only facts that benefit all of humanity, not give it to those for far fetched ideas that have no benefit to humanity.
If these amazing theories about the nature and origin of the Universe don't seem exciting or inspiring enough for you to consider them worthed then I'm sorry for you
This is the kind of corporate thinking that stiffels the expansion of universal knowledge and limits the possibilities of discovering any new wonderful things that aren't on the menu yet. Thinking that resembles a whirlpool as opposed to a starburst.
No, brother that will be a discrimination
When photoelectric effect got nobel prize,at that time that effect was totally useless for humanity
But today we are using it in our day to day life
You're talking about short term benefit. Impatience is damaging.
