Around 10:15 he says the new large hadron collider should be working soon. Also, i find it funny that instead of saying extra dimensions would be unstable, he says extra dimensions ARE unstable. He said that twice.
I love how Sir Roger still adheres strongly to the scientific necessity for evidence in a theory. He stated his lack of enthusiasm for extra spatial dimensions was the fact of no evidence for them. This gladdened my heart.
Why then do electrons have a spin of 1/2, which requires them to turn 720 degrees to make a complete cycle of spin? How is this possible in three spatial dimensions?
Until we can detect these so called extra dimensions then yes, in agreement with Penrose, they are merely mathematical sleight of hands... Still, only Evidence can rule them out, or indeed in... Entirely!

Perhaps our fabric of spacetime "brane" has a very high energy density and creates an extreme warp in the higher dimension, as suggested in the previous episode with Lisa Randall? Said higher dimension has collapsed, as suggested in this episode. Our fabric of spacetime "brane" is like a "4D Black Hole singularity" which has "pancaked" into a very thin 4D membrane in a higher dimensional hyperspace "bulk", and our "brane" is isolated from the rest of hyperspace by a "4D Event Horizon" resulting from the extreme energy density and resulting curvature?

Extra dimensions very smartly solve the problems of spookyness in Quantum mechanics. Because subatomic phenomena ocurre in higher dimensions as well and we only see the tip of the iceberg. That Quantum mechanics is so spot on is a tribute to the scientific method.
Extra dimensions seems resonable, and Intuitive as the explanation for spookiness. However, it is equally possible that quantum spin is a degree of freedom with a field all its own. Consequently, collapsing the entangled state by measurement, "instantly" results in both particles assuming their appropriate degree of freedom. Think of spin up and spin down as the peak and trough in a wave of any arbitrary wavelength, with some given amplitude. Remember, the entangled particles are created in one location and seperated to distant locations at speeds

Anything that can be represented on a scale is equivalent to a dimension. There are not a specific amount of spacial dimensions, we just use 3 so we can all overlay the same grid system.
Could compact small rolled up time dimension(s) be moving and leaving space dimensions as it passes? Maybe three dimensions of space associated with moving compact time dimension where it has been (past), where it is (present) and where going (future)?
fascinating ! It would be more convincing if Roger's theory can be proved by experiments, like the famous Galileo experiment that he dropped weights off of the Leaning Tower of Pisa, showing that gravity causes objects of different masses to fall with the same acceleration. After all the current spaceship are built based on dimension theory. Perhaps one day a spaceship can be built using Roger's theory, and can go faster than light. Or perhaps we can find a new particle that could not be found using conventional methods.
Spin can take infinite values after an interaction, leading to complexity. Collapsing extra dimensions maybe somehow related to these values. Extra dimensions are best visualized as qubits in superposition in a self-error correcting QC function leading to 'determinism'.
Isn’t Twistor theory merely a dual description of spacetime geometry? You do not need Twistor formalism to get complex numbers, since in real 4D space Clifford algebra already gives you the algebra of complex numbers, embedded as the even subalgebra. You can formulate QM entirely in terms of the real Clifford algebra, and it is more elegant than the corresponding matrix algebra. IMHO the real mystery of QM is not the appearance of complex numbers but rather the phenomena of entanglement.
That's not all it is, though the whole self-duality thing was one of it's rather large gaps. You don't need twistor formalism to get complex numbers, no, and yes, a (3,1) Clifford algebra gives you the algebra of complex matrices - eg. Dirac equation. A twistor is an ideal in the conformal (4,2) Clifford algebra (over the reals, I believe, it's been a while) … but seeing as it's 2019, it's probably worth skipping all this nonsense and focusing on the amplituhedron.😎
I agree with you, in terms of a lot of things could be done more "Beautifully" with Clifford Algebra(Geometric Algebra). I just recently got into Geometric Algebra, and it really is much nicer than just the plain Complex Numbers, it really does a great generalization and unifies a lot of things, or gives more intuitive feelings, for example with Quaternions and other things, meaning all things/realms of math that are related to complex/imaginary algebra or maybe I should say, makes use of these. But as Luca Thompson also said, the Twistor does have some advantages such as when dealing with Conformal Mappings. BUT, I believe in what you say Bijou-Smith, that Quantum Mechanics can be redone in terms of Clifford Algebra/Geometric Algebra. Doing Quantum Angular Momentum type calculations using the cryptic math of Wigner J-symbols math(Wigner 2j, 3j etc) is sheer madness. Even though the Bra-Ket inner product Hilbert space is used and made syntactic, meaning to shorten calculation in something like Wigner J-symbols math, I believe that Clifford Algebra may be able to properly simplify different areas of Quantum Mechanics, way better than they currently are. I think that maybe one should use Clifford Algebra to redo Twistor Theory. So thanks Bijou-Smith for bringing up Clifford- Algebra/ Geometric Algebra, in the discussions here.

I wouldn't even let the EU lot wire up my house they're that incompetant.
Elusive dimensions and perhaps even ascribed intelligence to those dimensions due to their bias towards being recorded. Consciousness is also very elusive though we are aware of its existence.
There is a ridiculously unimaginable number of dimensions and new realities are constantly being created. Since dimensions are constantly forming, there is, at any given nano-second, technically a finite number of realities, but from our perspective, we may as well say there are infinite dimensions. The Universe is a possibility factory and you need lots of Universes to fulfill every possibility.
Unfortunately, what you state declaratively isn't proven. There are an unimaginable number of dimensions... in the abstract. But in the physical universe? We simply do not know.
Just because there are many possibilities doesn't mean there is a universe to fulfill each one. If you don't agree, well... some evidence would be nice.
Second time to this video and im still feeling stupid because I find it hard to understand these mechanisms. Although English is my second language, I still think the guy is so smart compared to a knuckle dragger like me that I will have to listen to this five times to grasp something :D
The extra dimensions don’t need to be degrees of freedom. If you think of the universe as the 3D+time as the surface of a 4th dimension, then particles with mass may have a 4th dimensional component… and gravity is the topography of the 4th dimension. Gravity doesn’t extend into the 4th dimension its a 3D phenomenon from the displacement of space into the 4th dimension? Look at a 2d and model of gravity. The sun pushes down the 2d surface into the direction of the third dimension. 2d beings would wonder why their 2d plane was curved since they couldn’t detect the direction z. We can’t detect the directions Ana and kata, but when space is curved around the earth it doesn’t “bunch up” or “flow around” the earth, it gets occupied by mass and moves into the 4th dimension and back agajn. Idk.. just thinking out loud. We should preserve primrose as a head in a jar like futurama.

Enough to be out of the reach by our normal senses. How can you smell something if you don't have a nose? How can you know the world without sight, sound, and touch? Visible light is a small small fraction of the light spectrum. We need technology to help us see different waves. Imagine what is passing by in front of, but beyond our eyes. A good example is 2D to 3D. An object that can only go back and forth and left and right has no clue about up and down, but being in the 3rd dimension you can look down and see Mr. 2D he would have no idea that you even existed.

I have never known Sir Roger to be wrong about anything, judging by the tone of your sentence, I think the outcome you seek might be the one you don't want. You don't need to remind people to remember Sir Roger Penrose, in science, he is known worldwide. Make sure you remember him and perhaps learn from him.

Yes, mathematically, there are. But if they are so unstable in "real world" (theory) it would still be necessary to have evidence of existence, even if it's like evidence for Dark Energy. I can't wait ! sorry, just my impatience. :)
What are dimensions, nobody has ever seen anything less than 3. Sure we can imagine 1 or 2 dimensions, but we can't observe them. In mater of fact, even 3D geometry is just an idea, we live in a 4D space time. Whatever you do, things always contain dimension of height and never stand still. If there is a 5th aspect of dimension, it must be constructed and expanded from known 4, following same basic reasoning. Mathematics can construct many extensions to every day experiences, but those are just aspects of same dimensionallity, not separate things inside other things. Examples of such an expanded dimension would be space where universe exist or entire history, even those are debatable because idea demands we must elaborate what we mean by ordinary 4D space time Exactly? Relative to what, we can't always rely on geometry to describe how we perceive shadows on the walls of reality.

Four spatial dimensions are found below, and prove you are correct. Eph 3:18 May be able to comprehend with all saints what is the breadth, and length, and depth, and height; None of these brilliant men have ever fully explained how a universe can be formed from nothing, and with the correct fundamental forces of physics necessarily to produce our existence. What if "particles" are actually structures capable of storing spatial curvature. A wave of blue light contains more curvature in its sine wave than does a wave of red light. This applies the spatial curvature concept of general relativity to quantum mechanics. Higher frequencies are equivalent to more mass. Quarks could be twisted higher dimensional tubules that are intertwined with each other in the same way three twisted drop cords could be entangled with each other. Given the correct amount of twist and orientation, it could produce a stable proton. Therefore, "gluons" could be a higher dimensional part of each quark. The "Strong" force could be produced by particles being physically entangled. .
Sadly, I never am left with the impression that he is fully convinced of his thesis...perhaps because much of his professional work was eclipsed by Hawking...?
Nah. You just dont know Penrose. Hawking was great, but Penrose is just as great or evn better. If you were familiar with his other colloborations in different disciplines or even read his book, the emperors new mind, you wouldnt have such an impression.

Sure there is a way out of consciousness and common state of mind: 1) Force the body into a state of crisis where it is forced to react without conscious choice---how much do you remember eg a car accident? 2) Hallucinogenic drugs warp the conscious experience which is the end of the normal state of consciousness for the period of intoxication. 3) We can reduce metabolism via breathing techniques such as Pranayama, which leads to a semi hypoxic state in which conscious thought is slowed down. 4) Anaesthetic can abrogate consciousness completely whilst not killing you. Sleep is again completely different to normal conscious experience.
The dimension of time in the three spacial dimensions gives rise to the square root of a negative number. Time future and time passed. Negative or positive accordingly.

@@sebas793 No, I just don't think and feel that Penrose has. And bombast by his acolytes will not change that. Hawking and Guth have a more solid foundation to my mind.
Dimensions ? Parallel ? Parallel means, parallel Prespective of quantum particle, we are a Quantum Universe which exists everywhere to which no law applies. Thinking is a state of consciousness. No law applies to thinking. Thinking means, experiencing.work of consciousness. We are being experienced from the prespective of consciousness. Death is no such thing, meaningless event.

"Twister theory", LOL, I thought he was talking about a Christmas party game where you've got to get your hands and feet down on the right places when you're drunk.
I'm sorry....I have to call horse sh&% to his idea that the 3 spacial dimensions coupled with time cannot exist in any other spacial dimension other than our own. When common sense would tell us they can. The only change would be time. In smaller it moves faster, larger...slower. I'm beginning to think physicist today get lost in the math and lose all focus on common sense.
Um, why don't physicists look for something that they can actually perform experiments on? Like quantum entangled photons. Maybe they should brainstorm a new theory based on quantum entanglements. Because all this mathematical stuff that can't be tested is... useless!

But as Luca Thompson also said, the Twistor does have some advantages such as when dealing with Conformal Mappings. BUT, I believe in what you say Bijou-Smith, that Quantum Mechanics can be redone in terms of Clifford Algebra/Geometric Algebra. Doing Quantum Angular Momentum type calculations using the cryptic math of Wigner J-symbols math(Wigner 2j, 3j etc) is sheer madness. Even though the Bra-Ket inner product Hilbert space is used and made syntactic, meaning to shorten calculation in something like Wigner J-symbols math, I believe that Clifford Algebra may be able to properly simplify different areas of Quantum Mechanics, way better than they currently are. I think that maybe one should use Clifford Algebra to redo Twistor Theory. So thanks Bijou-Smith for bringing up Clifford- Algebra/ Geometric Algebra, in the discussions here.
Agree entanglement and non-locality.

@@noifurze6397 I mostly stumble with the question of where fiction goes over into reality.
Dimension joke
I think we all are lmao
Elusive dimensions and perhaps even ascribed intelligence to those dimensions due to their bias towards being recorded. Consciousness is also very elusive though we are aware of its existence.
There is a ridiculously unimaginable number of dimensions and new realities are constantly being created. Since dimensions are constantly forming, there is, at any given nano-second, technically a finite number of realities, but from our perspective, we may as well say there are infinite dimensions. The Universe is a possibility factory and you need lots of Universes to fulfill every possibility.
Unfortunately, what you state declaratively isn't proven. There are an unimaginable number of dimensions... in the abstract. But in the physical universe? We simply do not know.
Just because there are many possibilities doesn't mean there is a universe to fulfill each one.
If you don't agree, well... some evidence would be nice.
Second time to this video and im still feeling stupid because I find it hard to understand these mechanisms. Although English is my second language, I still think the guy is so smart compared to a knuckle dragger like me that I will have to listen to this five times to grasp something :D
If you're interested, that's what matters.
All scientific theories have to be consistent with the fact that we aren't all dead.
Nice one!
Is there a way to detect past time and future time dimensions? Memories seem to access past time dimension. Dreams can access future time dimension.
How can dreams access future time dimension?
Yes. Beyond the beyond and above the ceiling.
Well I wouldn't call them "extra" more then likely there is just enough!
Ha ha ha! But where's the evidence for that.
What if there are too few 😞
secondary object spirit, energy node space twist.
The extra dimensions don’t need to be degrees of freedom. If you think of the universe as the 3D+time as the surface of a 4th dimension, then particles with mass may have a 4th dimensional component… and gravity is the topography of the 4th dimension. Gravity doesn’t extend into the 4th dimension its a 3D phenomenon from the displacement of space into the 4th dimension? Look at a 2d and model of gravity. The sun pushes down the 2d surface into the direction of the third dimension. 2d beings would wonder why their 2d plane was curved since they couldn’t detect the direction z. We can’t detect the directions Ana and kata, but when space is curved around the earth it doesn’t “bunch up” or “flow around” the earth, it gets occupied by mass and moves into the 4th dimension and back agajn. Idk.. just thinking out loud. We should preserve primrose as a head in a jar like futurama.
Actually what is the full definition of the dimension? What is the full real picture of the dimension?
One definition is fractal dimension

@@piyush6494 yes he is very accomplished. However it is difficult to justify your position by telling people they are too stupid to understand. People don’t hear anything you say after you call them stupid. I enjoy listening to Roger and his ideas but he is not the best at communication. I understand that these things are complicated but if the concepts can be explained without insulting people there is a higher chance of success.
Sir Roger...
We know very little of what is reality. Anythying is possible. Our brains do not allow us to see almost everything.
This is my major issue with string theory as well. Your math doesn't work in our physical universe, so you just make up extra dimensions in order to shoehorn everything in there. Gonna need some evidence, chief.
Maybe the experiment is to difficult for current technology. Give it time.
A LOT of time.
Yes, evidence is paramount and absolutely essential. Today's fan boys haven't learned there is no shortcut to scientific knowledge, study first and learn, dream afterwards if you wish.
Totally agree
@@Hecatonicosachoron give it "millions upon milions..."
@@mileshall9235 well, that was an old comment... Anyway I am not sure why people expect experiments on at the energy scales of quantum gravity to be done now when the current highest energy experiments are at a scale that is smaller by something like 20 orders of magnitude
He's right.
Roger Penrose is the adult in the room.
Yes, the false fanatics are out in force, time for me leave before I get sick.
@@geoden Or he could be wrong.
I say it’s a definite maybe.
Riddles ;-)
answer. nope. There are just enough.
Enough to be out of the reach by our normal senses. How can you smell something if you don't have a nose? How can you know the world without sight, sound, and touch? Visible light is a small small fraction of the light spectrum. We need technology to help us see different waves. Imagine what is passing by in front of, but beyond our eyes. A good example is 2D to 3D. An object that can only go back and forth and left and right has no clue about up and down, but being in the 3rd dimension you can look down and see Mr. 2D he would have no idea that you even existed.
Quantum mechanics already uses infinite-dimensional objects. These dimensions are just not spatial dimensions.
when he said no evidence could he be more specific please to avoid being ambiguous
After 40 years of following Sir Roger's work, I've never found him ambiguous, if anything, he is refreshingly direct.
The Bermuda triangle is the easiest proof of extra dimensions. Where else do you think the things went?
Doesn't your superstring model answer that question?
String theory is accurate to a point but then it just gets silly.
You mean like heaven and hell? Science has truly come full circle to what humans have long believed .
The extra dimension the 5th dimension is our subconscious.
And could be proven mathematically .
You should ask *the greatest magician alive* Terrance Tow to discuss this idea with penrose and Zuckerberg to really define the question of what a dimension is for their respective fields 😂 and they might just get a eureka moment 😊
Could you repeat that?...

Remember that name -- Roger Penrose -- eventually, he will be proven right or wrong.
I have never known Sir Roger to be wrong about anything, judging by the tone of your sentence, I think the outcome you seek might be the one you don't want. You don't need to remind people to remember Sir Roger Penrose, in science, he is known worldwide. Make sure you remember him and perhaps learn from him.

Yes there are extra dimensions. 100%
Yes, mathematically, there are. But if they are so unstable in "real world" (theory) it would still be necessary to have evidence of existence, even if it's like evidence for Dark Energy. I can't wait ! sorry, just my impatience. :)
100% nonsense you mean!
What are dimensions, nobody has ever seen anything less than 3. Sure we can imagine 1 or 2 dimensions, but we can't observe them. In mater of fact, even 3D geometry is just an idea, we live in a 4D space time. Whatever you do, things always contain dimension of height and never stand still. If there is a 5th aspect of dimension, it must be constructed and expanded from known 4, following same basic reasoning. Mathematics can construct many extensions to every day experiences, but those are just aspects of same dimensionallity, not separate things inside other things.
Examples of such an expanded dimension would be space where universe exist or entire history, even those are debatable because idea demands we must elaborate what we mean by ordinary 4D space time Exactly? Relative to what, we can't always rely on geometry to describe how we perceive shadows on the walls of reality.
Heaven is another dimension. Prime dimension outside time.This dimension is construct.
@@robinbrown7028 It's hard to imagine not being something inside something else, would feel really weird if i could arrive before start traveling. Maybe we could tweak dimension a bit, but can never get rid of it, reality is a very persistent phenomena.
People's lives depends on natural laws, if those could change, their moral choices would be different.
@@robinbrown7028 "Heaven is another dimension. " What? Please educate yourself on some basic mathematics. We're talking about spatial dimensions, not some magical fairytale "dimension" like on TV.
@@robinbrown7028 If that is true then god would also reside outside of that dimension since he himself cannot be confined by dimension. He would predate dimension, and multiplicity.

Four spatial dimensions are found below, and prove you are correct.
Eph 3:18 May be able to comprehend with all saints what is the breadth, and length, and depth, and height;
None of these brilliant men have ever fully explained how a universe can be formed from nothing, and with the correct fundamental forces of physics necessarily to produce our existence.
What if "particles" are actually structures capable of storing spatial curvature. A wave of blue light contains more curvature in its sine wave than does a wave of red light. This applies the spatial curvature concept of general relativity to quantum mechanics. Higher frequencies are equivalent to more mass.
Quarks could be twisted higher dimensional tubules that are intertwined with each other in the same way three twisted drop cords could be entangled with each other. Given the correct amount of twist and orientation, it could produce a stable proton. Therefore, "gluons" could be a higher dimensional part of each quark. The "Strong" force could be produced by particles being physically entangled.

Sadly, I never am left with the impression that he is fully convinced of his thesis...perhaps because much of his professional work was eclipsed by Hawking...?
Nah. You just dont know Penrose. Hawking was great, but Penrose is just as great or evn better.

There is no way out of math , mind and consciousness, we are trapped forever.
Sure there is a way out of consciousness and common state of mind:
1) Force the body into a state of crisis where it is forced to react without conscious choice---how much do you remember eg a car accident?
2) Hallucinogenic drugs warp the conscious experience which is the end of the normal state of consciousness for the period of intoxication.
3) We can reduce metabolism via breathing techniques such as Pranayama, which leads to a semi hypoxic state in which conscious thought is slowed down.
4) Anaesthetic can abrogate consciousness completely whilst not killing you.
Sleep is again completely different to normal conscious experience.
@@dougmarkham I'll try some of those alternatives. Thanks.
Thats the end of time where all dimensions collapse and a new epoch begins.
The dimension of time in the three spacial dimensions gives rise to the square root of a negative number. Time future and time passed. Negative or positive accordingly.
Isn’t this all thinking and finding within the same, single box? Must be feeling trapped. Poor you all.
Drop the ‘extra’.
Then try ‘conditions’ and ‘manifest’ together. Nothing more. Just try it..
Roger what is wrong that the evidence points to a beginning and a beginning necessitates a beginner? Is not that obvious? If a ball flew into the room, would you not think that someone threw it, that there is a cause behind the effect? Roger do you want to live or do you prefer to die? Roger, Why? Why? Why?

Parallel means, parallel

Death is no such thing, meaningless event.
After death ? We will find overselves in the whole universe as consciousness.

At the moment we are experiencing through this body.
Creation has no meaning without experience.

Past present future running in nothingness.
Because, no law applies to consciousness.

I'm sorry....I have to call horse sh&% to his idea that the 3 spacial dimensions coupled with time cannot exist in any other spacial dimension other than our own. When common sense would tell us they can. The only change would be time. In smaller it moves faster, larger...slower. I'm beginning to think physicist today get lost in the math and lose all focus on common sense.
There are no extra dimensions, only the same amount there has always been .
he speaks like a mad man , this ignorant i am.
Um, why don't physicists look for something that they can actually perform experiments on? Like quantum entangled photons. Maybe they should brainstorm a new theory based on quantum entanglements. Because all this mathematical stuff that can't be tested is... useless!
Poor fool... Smart man. Swing and a wide miss though. This is what happens when the scientist's work becomes more important, to them, than the truth.
Sorry Roger..your wrong.
Hey just because we're not using them doesn't mean they're extra. Maybe they play a vital role without our knowing.
Wtf is he talking about..... ibwanna understand but cmon.......
