this is why I gave up on TV and watch TH-cam instead. Thank you for posting this!
TV pales in comparison to TH-cam.
That is why tv is called as "idiot Box" right from the beginning.
TH-cam is this generation tv and it's worse... And later it will be in your babies beads as chips... Don't get so high on this idea. And many very interesting talks are nothing but blasphemy and veil on the true light of god... But how can someone living in darkness differenciate between fire and light and light of god... How how..
@@MrPizzaboy19 loool
@@tyreza79 blasphemy? you are still living in mediaeval era. There is no place for such Stone age thinking and mentality in 21st century. God is not what you think or what you bealive. By saying things like "veil on true light of God" you are reducing god to just a weak entity who gets affected by deeds of humans. No it won't get affected. If it is all knowing all powerful,and present everywhere how can you call it as weak entity? Isn't this is sacrilege and blasphemy rolled into one? Acording to standard of mediaeval era thinking? Iam not saying god is not real. Iam saying you are misunderstanding the definition of God. There is no such thing as "personal god" god is not what you think or like to bealive. Can someone living in light or fire differentiate between dark and moonlight?
Light is shadow of God. Darkness is just absence of this shadow.
He gave this entire lecture in a single breath... amazing
...short lecture on a timeless topic!
Amazing talk and amazing attitude. This is the ethic and spirit true physicists bring in. Top of the line.
This should go viral and taught in schools. Thank you so much for this video.
There is no incentive to learn it :/
I love watching Nima. I don't have a ******* clue what he's talking about but his energy has filled me with enthusiasm for The End of Spacetime.
nothing new or profound on Nimas part, ( i understand there are lots of Nima worshipers here) these ideas have been around since Bohr and Einstein were debating one another. Both concluded there is a deeper reality that gives rise to emergent properties like fields and eventually particles.
@@fitnesspoint2006 We all already know that, but we LOVE NIMA.
@@beneu95 ood for you, do you want a cookie?
@@fitnesspoint2006 sure and we can go back to Plato or Liebniz or whatever you prefer for pure thought experiments that touch upon the same concepts. What is new and profound is that we can say with confidence that spacetime needs to be abandoned as a fundamental principle as a function of our best theories, and Nima is one of a handful who are pushing this research forward today.
@@sibbyeskie „we can say with confidence that spacetime needs to be abandoned“
No, we cannot. You haven’t understood much.
David Bohm and Jiddu Krishnamurti already talked about time being simply a perceived phenomenon while time in actuality eludes out of reality, stretches and dissipates. They also concluded that we don't even have the linguistic means to grasp this concept through the vocabulary available. Their series of discussion is called The Ending of Time.
Amazing stuff.
Physicists must never abandon the scientific method: experimental verification of all theories.
> experimental verification of all theories.
Like water finding its level!
@@rabbitcreative
It does find its level?
You bloody rabbits just sow disinformation, ever since the bunny wars of 1996. :P
Wow! What a badass, and his language to explain this all is so understandable... there's a lot to be said about those who can explain complex things simply.
Definitely found my next rabbit hole!
This is so key. Even in my own field, I feel like we're speaking a completely different language when simple explanations can be used instead so that others can share in the understanding and contribute their ideas, even to esoteric subjects.
The AI suggested this, the comments made me watch, and I loved it, simply revolutionary and brilliant.
A very "magical" lecture, thank you all very much.
"Magical"! Well said.
He strikes me as very particular with his words, and I would love to ask him why he chose some of the words he did :) "magical," "esoteric," etc.
delivered by a magician!

Thanks for exploring the bounds of the known world, and props to you for explaining it in a way plebs like me can follow. Good luck! I'll be cheering you on from the side of the field.
"I don't have time to talk about this in detail".
bu-dum-tst
That moment stood out for me too, haha
Thank you so much for posting this lecture with the graphics. Now I understand it better. 👍👍👍
Amazing talk by an amazing person. Thank you for this
Great talk, and a line of thinking way more promising than much speculative stuff that's going around.
Love it thank you so much!
👍 Thousandth Like!
Highly lucid description of the cutting edge, thanks so much!
Fabulous lecture, thanks.
Thanks a lot Nima for your real scientific attitude..I love it❤❤❤❤🎉
The Amplituhedron sounds *a lot* like Wolfram's Physics project (branchial space, the ruliad)... simple combinatoric graphs leading to emergent QM and spacetime physics.
Yes and what it likely means is spacetime is emergent from consciousness
@@JorJor812Elaborate please? Sources?
@@ehssandariani8041Donald Hoffman
Thank you for the video.
Ive seen and enjoyed several of Nima's lectures. I would be interested to hear his speculation on implications.
"In any system of energy, Control is what consumes energy the most.
No energy store holds enough energy to extract an amount of energy equal to the total energy it stores.
No system of energy can deliver sum useful energy in excess of the total energy put into constructing it.
This universal truth applies to all systems.
Energy, like time, flows from past to future".
@@ArmaGeddon-iu1vv Oh yes, "My body can do that". Stop having any meal and manage to grow food from scratch, awaiting it until you eat again.
Smart.
Thanks Nima for your great understanding and performance
Wonderful talk with a heads up on the possible shape of the next revolution in physics.
this is up my alley. lovely video!!!
You are a theoretical physicist too? That's so cool, man! Say hello to your brother Tony for me, pls.
Thank you professor.
Thank you Nima for these awesome explanations in layman s words that enabled me to make a mental image of particle scattering for the first time. you will most probably largely contribute to reveal what the world that we experience is made of. what i understand is that 4D space time emerges from basically one global 2D matrix of elements onto which permutations are performed. what would drive these permutations? the entropy variation rate of that information change would define the passage of time, right? you re getting closer to the argument that not only "reality" has all the features of a simulation but eventually, to the possibility that this simulation does not even need to be run to exist completely. i would really like to know what are the rules that govern the permutations of this large number of degrees of freedom arranged on a 2D grid.
What kind of simulation are you referring to? Hopefully not a computer simulation.
Donald Hoffman provides the answer in his “Fusion of consciousness” publication January 2023
This human concepts is all bs for bats, whales, trees, bacteria. They are not real only human ideas. Nice fairy tales.
How many dimensions are there? All of them. Our three or four dimension experience is vastly underdetermined leaving no way to 'solve' underlying mechanics of *the* universe. When randomness isn't. Still working on proton decay are they? They don't have the GUTs.
The simple gluon diagrams reminds me of Steven Wolfram’s graph project, right down to space time being emergent properties of more fundamental building blocks. Fantastic!
That was exactly what I was thinking!
I studied physics, biology and complex systems for about 10 years and the wolfram model for the past 2.5 years. In my study of those areas, they all inexorably led to the Wolfram Model…like a trail of bed crumbs.
The leap that needs to happen is letting go of particles and growup enough to stop smashing things together hoping to find meaning in the pieces.
He's a fantastic public speaker! I could not speak like that without forgetting my train of thought or which word I specifically wanted to use at least a dozen times lol
I am interested to obtain response on two separate questions related to topic presented here ;
1- Our World which we are able to observe is located in 3 dimensional space with 3 perpendicular dimensions. Such symmetry is sufficient to describe location all the points in the space. Symmetry of time is one dimensional- defining one time parameter is sufficient to locate the event in time. What is the physical purpose and sense to combine boths entities, with different symmetry? 2- Just on the begining during Big Bang all the energy and mass was collected together and it had not collapsed into one big black hole - only expanded violently and turbulently . Can we assume , that in this time the mass and gravitation was not present yet there and that the massive particles were condensed later on? 3- Has the physical Space any cohesion, which would bring the Space together to Big Collapse after all particulate matter will be swallowed by the black holes? 4-If so, it is possible, that our Space is oscillating in time interval 33 billions of years per cycle - in the space of diameter 0-120 billions of light years.
Stary
Space and time are concepts and no concept can capture reality. Concepts may be helpful at describing certain phenomena but ultimately they always limit and fall short.
Honestly I see this as the most fundamental important question in all of physics... "what is spacetime"
don't know, but like a VR headset we put on, meaning definitely brain generated, and all species of similar brains experience similar spacetime...

Great speaker gets ideas across layers of math, Nima is one!
However the great minds gets math across layers of ideas.
thanks for your persistence
Could the quantum field be the structure that QM and Spacetime emerge from or would the QF also be an emergent property? This is blowing my tiny mind.
Will you comment on "Impulse Gravity", experiment of Dr. Eugene Podkletnov, that propagates through vacuum at speed 64c (64 times speed of light) ?
What can I look up to learn more about that graphical representation of permutations?
Nice to see Persians doing awesome work
Great Talk !
As i understand it, the graphs are built on the principle of conservation of spin.
Size of lump here just correspond to the section of the lightcone 14:00
The boundary qft can be replaced by the deterministic de Broglie double solution theory (DST). I speculate, that DST=GR (ADM formulation)
I'm very much convinced, that boundary correlations can propagate as fast as you wish(several light cones in parallel). See papers by Gonzalez-Mestres. There's some fractal structure down there, beyond the uncertainty principle, in deterministic theory. Probably, self-similarity, even.
As much as I like the bootstrap program, i understand it still gives the approximate description of nature. It is unable to explain the speed of light. However, we know it is perfectly possible to calculate the speed of sound in a medium.
What is the interpretation adopted by Hamid Arkani to explain the problem of measurement?
Great lecture!!
Ah, this brings me motivation when I am too absorbed studying things in a tiny tiny little corner of this vast and rich field for my doctoral work.
Why do you burrow yourself like a rabbit in a tiny little corner to study and don't go out in the open or to the local library if you have no space at home? That cannot be very healthy and it probably affects your motivation negatively.
@@squarerootof2 It's been more than a year 😅. I meant that my focus of research is too specialised, as it happens to be the case in research after all. Not that I am working in a physically small space.

4:29 Just an observation: the size of the observable universe is not "10, 15 billion light years across", but over 90.
BRAVO!
Whenever I listen to Nima talking about space and time, I get a feeling that sone day Nima will incorporate mass, heat, gravity, energy, charge, spin etc., with space and time. Perhaps that day QM will be complete.
Wow- what a genius - love his dynamic quantum explosive humble truth- he tries top down load the perfect for us that we just take for granted.

Apophatic negation refers to a mode of inquiry that emphasizes what cannot be said or known about a given subject. In this approach, the focus is on negating or denying all positive assertions or concepts that might be applied to the subject, in order to point towards a deeper reality that transcends language and conceptualization. This is sometimes called the "via negativa" or the negative way. In the context of quantum physics, apophatic negation might involve questioning or denying common assumptions or theories about the nature of reality or the behavior of particles, in order to open up new avenues of exploration and discovery.
Cataphatic assertion, on the other hand, is a mode of inquiry that emphasizes positive assertions or concepts about a given subject. In this approach, the focus is on affirming or asserting what can be known or experienced about the subject, in order to develop a more complete and nuanced understanding. This is sometimes called the "via positiva" or the positive way. In the context of quantum physics, cataphatic assertion might involve formulating hypotheses or theories based on empirical observations or mathematical models, in order to test and refine our understanding of the underlying phenomena.
Theoria apophasis is a combination of both apophatic and cataphatic modes of inquiry, in which the emphasis is on a dialectical process of negation and affirmation. In this approach, the focus is on using the limits of language and conceptualization to approach a deeper, transcendent reality that cannot be fully captured or comprehended by any positive assertion or negation. In the context of quantum physics, theoria apophasis might involve using the constraints of experimental data and mathematical models to refine our understanding of the behavior of particles, while also acknowledging the limits of our knowledge and the potential for unexpected discoveries.
Overall, these modes of inquiry can be seen as complementary rather than mutually exclusive, and can be used in various combinations depending on the goals and context of scientific inquiry in quantum physics and other areas of study.
Interesting . Do these modes of inquiry arise from philosophical thought or are they an inherent aspect of the scientific method ?
AWWESOME!
Bravo , proud of you as a n Iranian first class theoretical physicist.
Wolfgang Pauli , a LMU graduate like myself, said at the end of a conference he listened to : Alles falsch.
Time is only defined as when points in space are moving and changes position. Every single point has it own time. The time we see may be called "statistical" time. Many points together makes your reality.
As a fairly bright layman I understood this fellow, credit him with bocu kudos.
From the perspective of a human riding the arrow of time, I accept that what happens within my life will always be there,
*but will I perceive being there/here after my arrow of time runs it's course?*
I can imagine that I may not remember each time I ride that same arrow, but the perception of it, is "that" dead or alive after death? Could/can it only be perceived once?
My questions are these: why does anyone think that abstraction precedes complexity in a very physical sense? Why is abstraction not simply the generalisation of directly observable phenomena? Why must we sum up complex interactions to a simple solution, and can we? And why must this abstraction supercede geometry in some more fundamental way? Especially if we need to observe the geometry to deduce it? And knowing human beings are known for their tendency to categorise?
Could it not be that what we see is what we get, and geometry is simply complex? That physics is a good summary of many situations, but searching for a *deeper* answer is meaningless without observing deeper interactions?
What purpose does the search for depth serve if it doesn't directly allow us to solve observable mysteries, namely dark matter and dark energy? What purpose does trying to reinvent geometry in abstract space hold if it does not relate to observable spatial, time dependant phenomena? Where did that abstract space come from? All this does is displace the need to explain an origin, (which by the way cannot exist, the idea of a first thing is impossible) to an abstract space. Why not keep it in a physical space? It sounds like, in your search for simplicity you have made the required explanation more complex. Like QM. Pushing the explanation into an abstract space - the wave function - that has no causal explanation and just exists. Why is this a more convincing explanation, physically? What problems does it help to solve?
Physics is not what the world is, it is what the world does. In my view we should focus on explaining the mysteries first, and once all of them have been elucidated, that will be the proper physical framework, and I guarantee this will link QM and GR. The unity will emerge from the problem solving. You don't first create an abstract unity then try to apply it to everything. That sounds very inefficient. To me.
Physicists have made Nature and life complex. It is time physicist look deep into Nature and Life - Look Within
So Cool.
J'adore ce mec!
Why must abstraction be conceived to precede classical physical existence? Does abstraction not arise from the physical classical **observation** of physical existence?

Today we are asking about quantum entanglement, non locality, and information exchange...

Continue thought: because there is no gravitational pull in space unless each energy has some sort of gravitational field where they attract each other…while flying through space as space expand. Perhaps energy is moving faster than the rate of universe expanding

Nice talk.
I wonder what Einstein would think about the idea that both Quantum Mechanics and Space Time emerged out of something else.I bet both him and Bohr never thought of that.
So far I call it "Infinity" and the "What not" or "Not what" dimension, which is infinite and yet contains all possible limits and physical potentiality. This has been an ongoing investigation for me since early childhood. Like Nima, I am hooked but he is more advanced than myself, especially in math.. I will continue... As for Einstein , Bohr and others, I think they knew there is more but they could not prove it.
Discovering the cause-effect of superimposed wave-packaging distances with frequencies is, of course, what Galileo taught us about Measurement = Physics, and Dirac suggested the inverse or reciprocal connection, based in a trust that mathematically, the significance of "Large Numbers" would reveal "Everything" speaking Quantum Mechanically, which is why the inversion of a wave-packaging Partitioning of the Fine Constant 137.., by say a Reciproction-recirculation Quantum Operator-Oscillator harmonically resonant in superimposed Gravitational frequencies.., then there's a harmonic frequency density-intensity in line-of-sight probabilistic superposition identification of Actuality, the Quantum-fields Mechanism Holographic standing wave modulation in Principle expected by Observation of WYSIWYG, learning by doing, particularly using projection-drawing techniques Actual Intelligence of Universal Existence phenomena.

Although the patterns of things and behavior in the universe appears random and sometimes chaotic and rather unpredictable, they all follow specific mathematical principles CONSISTENTLY. Mathematics is the underlying abstract principles governing where the universe came from and where it is going. Can we then say mathematics rules the universe?
One of several things I didn't quite understand from the talk, I'd like to throw out here: Nima talked about gluons (perhaps he could have used other particles, I don't know), but it seemed that somehow, he retains 'particles' such as gluons etc, as entities in themselves, but the 'arena' as I call it, of interactions is where the differences between today's QFT and his concepts of possible new physics lies. I guess my question is that I don't seem to understand if 'particles' are real entities in themselves or 'emergent' parts of something deeper.
All particles are fluctuations of fields
