thank u
thx
he’s so understated and unpretentious, really strikes the perfect tone in order to convey his ideas well. Love learning from him.
Listening about the rotation and involvement of complex numbers, which actually describe rotation, reminded me about Quaternions. It is important to notice that this knowledge we called today, Maxwell theory ( usually just mentioning Maxwell equations ), was first expressed in 20 Quaternion equations and for about 18 years no one really understood what they expressed. It was the advent, of the self thought mathematician and physicist Oliver Heaviside, to translate and extend the Maxwell theory and morfed his equations to the vectoral form we know today. These 20 Quaternion equations became the 4 vector based Maxwell, actually Maxwell-Heaviside, equations, in the form being thought in the educational system.
The pedagogically correct and modern form is in differential forms, and further the Yang Mills equations - more geometrically motivated
They call Susskind the bad boy of physics, but I've always thought it was and is Penrose
He's a kind of sus
Well Susskind had the whole idea of string theory and the holographic principle, which witten used to propose the idea of twistor string theory, and there are papers by others further developing that idea, so there's maybe a direct connection between their ideas actually.
A true giant of physics. Thank you Roger Penrose for your contributions and your humbleness. You are a treasure and inspiration.
Amazing how alive smart people remain to the oldest age. He's almost 90, yet so enthusiastic and vibrant, and still has many plans for his life.
Wish you good health and many more years to live, good sir.
The most shocking thing was the interviewer's voice and the end of the video. Thanks for sharing your knowledge, Roger.
I love it how he is a genius but also very humble. He never gives his opinion about all kind of unrelated things he doesn't know very well.
The greatest scientists always know that they might be wrong, so are never arrogant.
Yes, this is just standard protocol among top scientists with earned reputations they care about. One can, however, always qualify a non-expert opinion by saying, "My conjecture on that would be...", or with an even lower "Bayesian prior" (probability of being substantially correct), "I might offer an educated guess, though...", etc. Scientists don't have to keep mum with opinions on other disciplines, religion, or politics... they just need to speak clearly, with some reference to evidence, and define their terms so that most thoughtful and open minded people can be "on the same page" (more or less!).
@@frederickj.7702 my non-expert opinion is 375 jumped the fence and no one ever figured out what he ran from.
Thank you Mr Penrose for that explanation. The clarity of it, to my mind emphasizes the deep grasp you have of a complex subject which you explained beautifully to a layman like myself. The world is a better place for having you in it. My deepest respects Sir.
this man will go down in history one day. twister theory, specifically geometry and vibration is the key to physics and the universe.
He is the Nobel prize recipient!
Since an electron has properties of both a particle and a wave, it must be neither.
Taking the curvature of space-time to the quantum level is a brilliant solution to the problem.
Twisted tubules of a higher dimensional membrane might be helpful.
Perhaps at some level h is equivalent to one cycle of spatial curvature, as in the coils of a spring.
If the springs become entangled, could it explain the Strong nuclear force?
Big man. Great greetings to him.
I just love listening to this guy. A true genius of the highest order. What a pity that he has never become a household name in the same way as Einstein or Hawking. I know there are others about whom the same complaint could be made (eg Feynman) and I guess it just shows that we are a very shallow society interested in the superficial only. 😔
finally got it to play for me.. makes you think... I still do not know much about "twister theory" but I am going to look into it a bit more.. Well done Roger!
Still haven't a clue..
Penrose is a God.
Actually he is a human being of flesh and blood, which is far superior.
@ Amere Mortal... Tsk, tsk... Jahweh will not be pleased... speaking of someone with notable anger management issues!
I love this guy.
Good question!
Who the hell would downvote Roger Penrose talking about twistor theory.
1. A member of the current U.S. executive branch of government? 2. A self-identifying Evangelical "true Christian" [sic]? 3. A hyper-authoritarian anti-empiricist who views physical science and mathematical / statistical methods as a "religion"? 4. An habitual, "willful" 'idiot'; or person otherwise psychologically impaired to the point of gross disfunction?
...Oh, wait, perhaps I am being somewhat redundant here.
@@frederickj.7136 You forgot one catagory.
-People expecting a video on 'Best '70's era orgy games'.
@ OrigamiOwl... Ah, well yes... and I'm old enough to remember when that party game first appeared -- predating, at least by a little (I'm assuming), the realization of any potential it had for orgy warm up applications. In those days, predating Tumblr, et.al., turning a kiddie competition to win into ("decently" clothed) 'full body contact Pass the Orange', a game where everyone in mixed company presumably wins, was risqué enough for most youthful participants!
Probably just someone who's bitter and twisted
I think some people downvote as a substitute/instead of pressing “not interested’ maybe.
What a giant of science!
I love this amazing man.
Perhaps the gravitons move with the direction of the body's gravitational field. So expressed as a particle it can only relate to the particular direction of the body right or left to the frame of reference. I'm not a scientist so feel free to correct me.
Thankyou
Wonderful
Penrose is a genius...... and of course, helped out here by a few random bass guitar notes....
Thanks , is it end of spacetime or transformation into some other more comprehensive continum like Mind-Self Continum ? Prof Penrose may be called a cosmological version of Planck and contemporarybversion of Dirac
Apologies Sir Roger, I simply had to youtube "How to bowl a Googly" halfway through this clip.
Is it about movie twister
Roger Penrose is the life of the party once the Twistor game comes out! Right-handed up quark yellow. Left-handed down quark blue. The game that turns spacetime inside out!
Fascinating but would be better if it were longer.
It is both longer and better :D czcams.com/video/9Gl8pwY2kW8/video.html

Re: the thumbnail pic, et.al. -- Roger more resembles Lonesome George, the famous and celebrated centenarian tortoise (or E.T.!), every time I see him... just with glasses. The last of his subspecies -- Homo sapiens sapiens physicisticus -- to still use the classical A-V nerd overhead lens projector for presentations?
EDIT: Sir Roger has recently come to adopt Keynote, or Powerpoint, or ??, I see. Old dog, new tricks department.
@@frederickj.7702 No more crinkly transparencies? No more overhead projectors? Why, 'tis more than flesh and blood can stand!
There are a few more bowling styles mr.penrose. One is called the carom ball that ravichandran aswhin does from India, U should try!
Where they use statistics in physics, they are working with a least one dimension less then it should to take out the guess work we see in statistics.
To me it sounds as if space-time itself is directly affected by our observations. To me this tells me that, perhaps the power of belief itself could be real if it has such a profound effect on the universe.
The *twistor theory* is the regurgitated *vortex theory* by Rene Descartes the French mathematician and philosopher of the 17th century.
Such Brilliance put in to laymans terms that alone has got to be hard for him. Funny it seems like the more you learn the less you realize you really know:-)
Vector (4d photon) ->Sector (5d spinor) -> Tector (6d twistor)
The Googly Problem. 40 years a' wanderin', eh? Then the sea parted almost straight down the middle, making way for a clean run to t'other side.
Simply put, twistor theory is the theory of twistors.
If you need more information, I'm sorry but I can't help you.
An intellectual journey of a thousand miles begins with a single copydot...
Did I hear him say there could be a form of space without time, and that events would still be occurring there? Time is defined as a measurement of events so if events are happening the concept of time is in play despite the # of dimensions.
@@anuraagpaul6610 wrong. Time is a measurement of events. End of story. Grab a dictionary
@@anuraagpaul6610 We can talk about Twistors...But if we are talking about TIME, it's important we use proper definitions. Your trolling is lazy and weak
@@anuraagpaul6610 that's simply false. Open a dictionary and read the formal definition of time. You lose
@@anuraagpaul6610 if I'm talking about what time is ill use the formal definition thanks 😊
@@anuraagpaul6610 the problem is I'm not talking about twistor space...I'm talking about time...you commented under MY post so stick to what IM talking about or you're irrelevant
This guy is way too smart...
I don't believe there is something as spinning right sor spinning left. It's just a matter of perspective.
Chirality is the same from all perspectives for particles moving at the speed of light, which is what Penrose refers to here. This is because you can never overtake particles moving at c, so their "rotation" with respect to their velocity will always be left or right handed.
For an object moving slower than c this would net be a constant, once you move faster than the particle the chirality flips.
There are 4 parts to the whole of movement of an atom in space time geomoitry.
Imagine all particals going into a black hole. When these photons or electrons come to a stop within the B H, they are shown as 4 corners of the same reference. But there colours are different.
I found this whole egg n I was young and they will understand one dau
@stoeger 2 there are more than 4 aspects the OP is dunning-kruger. There are 4 basic degrees of freedom to start. 3 vectors xyz and the charge. You can expand it to colour charge with quarks and the SU(3) group symmetry which needs 7 degrees total. But to add metric tensors for everything you need 14. Including oscillator function. Amplitude. Frequency. And wavelength for the wave descriptor partition. The curvature of a black hole causes world-line axes to flip and it will fall through time as the space. And travel in space at a linear time rate. You fall toward the singularity just like we fall toward the future 1second at a time.
Interesting, that weinstein, surferdude and sir. Penrose all talk about beauty as they fell in love with their ideas maybe too much, although i fully get why they did.
@@DerpMuse also the above is on top of all the 11 dimensions. Think of it as on the outside of our universe
Guys thanks for replying I want to move our understanding of what we live in forward.
I found this whole looking deep within, although I can't prove it.
There is so much more than what we currently think we know and ideas are the keys to further understanding
Was he at a concert ?
I just got flipped off by Sir Roger Penrose at 1:02
did he really just say graviton? :p anyhow nice to listen him explaining this theory
Graviton, if you choose to see it that way. I doubt he's claiming they're real
@@MagicToadSlime then why does he mention it? and why would he say this and not gravitational forces or gravity?
Because the graviton is the theoretical particle (although not really a particle?) that transmits, or mediates the gravitational affect. As the photon is connected to electromagnetic force... I know, it is strange because we have become used to the idea that gravity is an effect of spacetime curvature.
Don't understand any of this really but fascinating nonetheless 🤯
@@majorcatastrophe2829 yeah i'm aware its something theoretical, i find it to be one of the more extreme concepts in the quest to explain gravity.. but to be honest i kind of think spacetime bending is also strange, i'm not a student of particle physics, or astronomy (university) but the last few years all my spare time has gone to reading physics, as in trying to grasp the concepts, not doing the equations as my mind isn't trained for it (i was an art student and couldn't care less about maths and such :p )
i find it weird to give properties to space other then a vector 3d thing where stuff can move or things can happen, its fine if its given a geometric structure as long as it stays clear this is just to help certain dynamics being calculated etc..
on the particle physics topic i've found some effects to also be weird like quantum tunneling, it's one thing to explain this in tech where the distance is measured in nm but something else when we talk about stars..
ah well i'm sure many concepts are more like a human interpretation then the real workings of nature, but it's fascinating to see how close we can get..
I feel like a dunce trying to wrap my head around this
take my money
calling it a googly problem seems like the most english thing ever
Interesting penrose watch cricket
I didnt think people believed in graviton anymore.
by graviton, he only meant conformal curvature of space time, nothing more than that
hummm won't play this time 7/02/19! I wonder if this comment will show up?
yes?
@@Reignor99 thanks Sloop..
@@tinkmarshino What was the point of your comment? (sincerely curious)
@@Reignor99 I tried to listen to the video and it would not play for me on my system.. I watch other videos but for some reason this one would not play.. very strange.. But thanks for reminding me I will go back today and try again.. I wanted to hear what Dr Penrose had to say.. he is a very brilliant man.. What did you think of this video?
@@tinkmarshino I think the video did not help me much to understand Twister Theory.
I enjoyed listening to Penrose talk, but I can't think of much that I learned from it, other than what a "Googly" is.
Actually the dimensions are 1%29th in oxygen
I'd you want a mirror.. just think a mirror..

only took about 40 years .... eh😅...
So Shane Warne knows all the mysteries of the Universe, given he has perfect knowledge of the googly problem.
I still didn’t understand Twister Theory. Can someone please help me? ..... But he mentions Gravaton. Who says that Temperature has particles? Gravity is Energy, Gravaton doesn’t exist!
Quantized Inertia And energy is quantized. Every single quantum of gravitational energy is called graviton.
Gravity is a wave. Therefore it exits in particles.
Just like light and photons.
@@xohnoezxgaming1402 You state that so matter of factly. What evidence exists to suggest gravity is a wave?
@@CallsignJoNay the detection and observation of gravitational waves by LIGO perhaps?
@@justdave9610 I think you misunderstood the experiment. Ligo does not prove that gravity is a wave the same as electromagnetism. The experiment showed that waves can propagate in space time. Think of spacetime like an ocean. Just because waves can propegate in an ocean does not mean that water is a wave the same as light.

Job 38:1-38 KJV
1 Then the LORD answered Job out of the whirlwind, and said,
2 Who is this that darkeneth counsel by words without knowledge?
3 Gird up now thy loins like a man; for I will demand of thee, and answer thou me.
4 Where wast thou when I laid the foundations of the earth? declare, if thou hast understanding.
5 Who hath laid the measures thereof, if thou knowest? or who hath stretched the line upon it?
6 Whereupon are the foundations thereof fastened? or who laid the corner stone thereof;
7 When the morning stars sang together, and all the sons of God shouted for joy?
8 Or who shut up the sea with doors, when it brake forth, as if it had issued out of the womb?
9 When I made the cloud the garment thereof, and thick darkness a swaddlingband for it,
10 And brake up for it my decreed place, and set bars and doors,
11 And said, Hitherto shalt thou come, but no further: and here shall thy proud waves be stayed?
12 Hast thou commanded the morning since thy days; and caused the dayspring to know his place;
13 That it might take hold of the ends of the earth, that the wicked might be shaken out of it?
14 It is turned as clay to the seal; and they stand as a garment.
15 And from the wicked their light is withholden, and the high arm shall be broken.
16 Hast thou entered into the springs of the sea? or hast thou walked in the search of the depth?
17 Have the gates of death been opened unto thee? or hast thou seen the doors of the shadow of death?
18 Hast thou perceived the breadth of the earth? declare if thou knowest it all.
19 Where is the way where light dwelleth? and as for darkness, where is the place thereof,
20 That thou shouldest take it to the bound thereof, and that thou shouldest know the paths to the house thereof?
21 Knowest thou it, because thou wast then born? or because the number of thy days is great?
22 Hast thou entered into the treasures of the snow? or hast thou seen the treasures of the hail,
23 Which I have reserved against the time of trouble, against the day of battle and war?
24 By what way is the light parted, whichscattereth the east wind upon the earth?
25 Who hath divided a watercourse for the overflowing of waters, or a way for the lightning of thunder;
26 To cause it to rain on the earth, whereno man is; on the wilderness, wherein there is no man;
27 To satisfy the desolate and waste ground; and to cause the bud of the tender herb to spring forth?
28 Hath the rain a father? or who hath begotten the drops of dew?
29 Out of whose womb came the ice? and the hoary frost of heaven, who hath gendered it?
30 The waters are hid as with a stone, and the face of the deep is frozen.
31 Canst thou bind the sweet influences of Pleiades, or loose the bands of Orion?
32 Canst thou bring forth Mazzaroth in his season? or canst thou guide Arcturus with his sons?
33 Knowest thou the ordinances of heaven? canst thou set the dominion thereof in the earth?
34 Canst thou lift up thy voice to the clouds, that abundance of waters may cover thee?
35 Canst thou send lightnings, that they may go, and say unto thee, Here we are?
36 Who hath put wisdom in the inward parts? or who hath given understanding to the heart?
37 Who can number the clouds in wisdom? or who can stay the bottles of heaven,
38 When the dust groweth into hardness, and the clods cleave fast together?
Love this guy, but this is pure rambling
Perhaps Shane Warne will know the answer !
Time is everything, gravity & matter are misinterpreted. Time mechanics.... we are sensing time incorrectly. Interactions = more time. Space isn’t expanding interactions are. Everything is time.
Physics is such an awful mess right now.
I can’t imagine how imaginary numbers have anything to do with reality...I just can’t.
This is supposedly "the elder" in physics. Why has he seemed to "tap out" and give up on the institution? He isn't supporting any up and coming theories or individuals, he isn't a leader in the field (by show of behavior / actions NOT his applications - obviously). If that's not his position, fine. But go on record and say why (FREE SPEECH) NOW is the time.
Weak Theory. It's turtles all the way down.
What is preventing the physics community from figuring out how to create warp fields? We need less mathematics and more experiments that have a chance of finding new phenomena.
Uh… money.
Senseless gibberish.
EINSTEIN NEVER UNDERSTOOD PHILOSOPHY, MATHEMATICS, AND PHYSICS, AS HE HAS BEEN TOTALLY OUTSMARTED BY SIR FRANK MARTIN DIMEGLIO:
The balance of being AND EXPERIENCE is ESSENTIAL. BALANCE AND completeness go hand in hand.
THE SELF represents, FORMS, and experiences a COMPREHENSIVE approximation of experience in general by combining conscious and unconscious experience. MOREOVER, the ability of THOUGHT to DESCRIBE OR RECONFIGURE sensory experience is ULTIMATELY dependent upon the extent to which THOUGHT IS SIMILAR TO sensory experience. THOUGHTS ARE INVISIBLE.
Dream experience is/involves true/real QUANTUM GRAVITY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. MOST IMPORTANTLY, in dreams, BODILY/VISUAL EXPERIENCE is invisible AND VISIBLE IN BALANCE. IMPORTANTLY, dream experience is possible/potential AND actual IN BALANCE. THE EYE is ALSO the body. Dreams improve upon memory AND UNDERSTANDING. Indeed, there is no outsmarting the GENIUS of dreams.
OVERLAY what is THE EYE in BALANCED RELATION to/with what is THE EARTH. NOW, get a good LOOK at what is the translucent, SEMI-SPHERICAL, QUANTUM GRAVITATIONAL, AND BLUE sky. Excellent. The DOME of a person's EYE is ALSO VISIBLE. THE EARTH IS also BLUE (as water).
F=ma AND E=mc2 PROVE that, why, and how ELECTROMAGNETISM/ENERGY IS GRAVITY. This NECESSARILY represents, INVOLVES, and describes what is possible/potential AND actual IN BALANCE. SO, it is NECESSARILY a matter of precisely how these equations are understood in a BALANCED, EXTENSIVE, AND INTEGRATED fashion in RELATION to/with WHAT IS THOUGHT. The INTEGRATED EXTENSIVENESS of THOUGHT (AND description) is improved in the truly superior mind. E=mc2 is DIRECTLY and fundamentally derived from F=ma.
Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black.
The stars AND PLANETS are POINTS in the night sky. 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. Get a good LOOK at what is THE EYE. POINTS are points. Gravity IS ELECTROMAGNETISM/ENERGY. ELECTROMAGNETISM/ENERGY IS GRAVITY. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent with/as what is BALANCED electromagnetic/gravitational force/ENERGY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. F=ma AND E=mc2 PROVE that ELECTROMAGNETISM/ENERGY IS GRAVITY, AS ALL of SPACE is NECESSARILY electromagnetic/gravitational IN BALANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GREAT.
The stars AND PLANETS are POINTS in the night sky. OPEN your EYES. NOW, LOOK at what is the FLAT, SETTING, AND ORANGE SUN (with the SPACE around it THEN going invisible AND VISIBLE IN BALANCE). This ORANGE SUN manifests or forms at what is EYE LEVEL/BODY HEIGHT as well. This ORANGE SUN is manifest ON BALANCE as what is NECESSARILY the BODILY/VISUAL EXPERIENCE of THE EARTH/LAVA. The viscosity of LAVA IS BETWEEN what is manifest as WATER AND THE EARTH/GROUND. ALL of SPACE is NECESSARILY electromagnetic/gravitational IN BALANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. F=ma AND E=mc2 do provide absolute, BALANCED, THEORETICAL, and CLEAR proof that ELECTROMAGNETISM/ENERGY IS GRAVITY.
Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. THEREFORE, the rotation of THE MOON MATCHES it's revolution. MOREOVER, a given PLANET (INCLUDING WHAT IS THE EARTH) sweeps out equal areas in equal times; AND this is THEN consistent with/as what is F=ma, E=mc2, AND what is PERPETUAL MOTION; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. It ALL makes perfect sense. BALANCE AND completeness go hand in hand.
THE PLANETS (INCLUDING WHAT IS THE EARTH) are NOT "falling" in what is "curved SPACE". In fact, this is nonsense. It is PROVEN.
By Frank DiMeglio
Absolute nonsense.
Penrose has been banging on about complex numbers since 1972. It's his explanation for everything. Talk about a one-trick pony, I notice he says the mathematics is beautiful, but he can't explain how his theory describes how the universe works, the only thing that counts. He's talking about gravitons and photons travelling from point A to B at the speed of light. He needs to retire and stop wasting people's time.
