Neil Turok is a professor at the University of Edinburgh where he holds the Higgs Chair of Theoretical Physics. He acted as the director of Perimeter Institute from 2008 to 2019 and now holds the Carlo Fidani Roger Penrose Distinguished Visiting Research Chair in Theoretical Physics at PI.
In this episode of Conversations at the Perimeter, he talks about his recent work that describes the Big Bang, how his research has been influenced by Stephen Hawking, and why he chooses to work on theories that have the potential to be proven wrong.
He also talks about his time as director of Perimeter Institute and describes the strategies he used to create a culture and community capable of fostering breakthroughs. It's a fascinating conversation, and Neil is uniquely gifted in describing both the biggest questions in theoretical physics and the best strategies for answering them.
Conversations at the Perimeter is co-hosted by Perimeter Teaching Faculty member Lauren Hayward and journalist-turned-science communicator Colin Hunter. In each episode, they chat with a guest scientist about their research, the challenges they encounter, and the drive that keeps them searching for answers.
The podcast is produced by the Perimeter Institute for Theoretical Physics, a not-for-profit, charitable organization supported by a unique public-private model, including the Governments of Ontario and Canada. Perimeter Institute acknowledges that it is situated on the traditional territory of the Anishinaabe, Haudenosaunee, and Neutral peoples. Perimeter’s educational outreach initiatives, including Conversations at the Perimeter, are made possible in part by the support of donors like you.

Two people communicating is a dual process! The master (teacher) is dual to the apprentice (pupil) -- the rule of two, Darth Bane, Sith lord. Communication:- Sender is dual to receiver -- messages. Vectors (contravariant) are dual to co-vectors (covariant) -- dual bases. Riemann geometry is dual and therefore curvature or gravitation is dual. Positive curvature (convergence, syntropy) is dual to negative curvature (divergence, entropy) -- Gauss or Riemann geometry. Syntax (categories, form) is dual to semantics (sets or objects, substance) -- languages, communication. If mathematics is a language then it is dual. All numbers fall within the complex plane, real is dual to imaginary -- complex numbers are dual. The integers are self dual as they are their own conjugates. All numbers are dual. Numbers connect the classical world with the quantum world -- quantum gravity. Classical reality is dual to quantum reality synthesizes true reality -- Roger Penrose using the Hegelian dialectic. Energy is dual to mass -- Einstein. "Always two there are" -- Yoda. Interviews are inherently dual as they require two observers.

Niel Turok is a great inspiration to anyone who wants to enter the world of science and not just theoretical physics. The insights and ideas he shares are very universal to science itself as he says in the video and I paraphrase "we in the theoretical physics are very cheap. We can reorganize the structure of how science is done in theoretical physics more easily than in any other field" This is not his exact words but that what I understood. I encourage anyone wanting to enter the world of research and science to listen to this interview and pay attention to what we can learn from 1. The process of doing science 2. The motivations of a person doing science and 3. How to be driven by ones own desires and questions and still contribute and be "useful" to those who employ, recruit or admit us to the institutions that are publicly or privately funded. In other words how can one be a responsible member of society without giving up any of our true innate passions. I am sure you will pickup a few tips at least from Neil Turok in this video interview.

He and Penrose amaze me in their ability to explain to lay people the short comings of modern physics, the problems with current theories and some of the new solutions and where they came from. So many of the lectures you hear talk about the current theories and how they work so well, but very few are willing to talk about where the current theories are breaking down, the contrarian views and how they are revolutionizing modern physics. This is an amazing video, on par with several of the talks with Penrose that were posted in the last several years.

When I studied physics in the early1970s (I later switched to computer science), as an undergraduate student, I worked (paid position, where I learned to program and learned a lot of statistics) in the High Energy Physics (HEP) department, an experimental group. This was at a large state university in the US. We had most of the top floor of the rather large physics building, but there was one, smaller, wing of that floor with theoretical physicists' offices. In fact, Misner's office was there. Although we were all interested in General Relativity and got the book "Gravitation" by Misner, Thorne and Wheeler, I don't recall ever going down to their offices to talk, or even say hello. We had weekly departmental seminars, which covered both theoretical and experimental topics. So, there was some interchange there. We would even go to the Cosmos Club for seminars when one of our professors was speaking. When there was a big topic there would be all department meetings. Two I remember. One was when it was thought a magnetic monopole had been detected. The other was when GPS turned on and the use of Einstein's theory on that was discussed.

Adding extra particles is reminiscent of the attempt using cycles and epicycles to describe the motions of the planets. When simple circular motion was not quite right, epicycles were added in an attemp to get a better fit. Eventually the dogma of circular motion was abandoned in favour of elliptical orbits.

Wonderful lecture. More people should listen and learn from this individual's approach to difficult problems. I was really taken with the idea of a Plan B. This applies everywhere, not just in Physics. It is a very old idea, that one should develop a primary skill set and make it your life's work. But at the same time develop a secondary skill set as your Plan B. If something happens to the marketplace of ideas or things of your primary, one can then fall back on their secondary. All plans great and small should have a backup plan.

Even if in the end it doesn't turn out to bear fruit atleast the entire basket, there's always something positive that shines through. Gravity has weighed physics down for 100 or so years and has kept us grounded in more ways than one. It's time so to speak to move forward and outward away from the atmosphere environment.

After causing a small explosion in Chemistry, I was kicked out at 15 by an itinerant young teacher who btw would answer any questions outside the text with "I don't know" (our migrant school couldn't find permanent science staff). After 60 years of wandering under the stars, I finally got a job in cancer research which I love. A series of lectures by Leonard Susskind took me into rabbit holes of supersymmetry and possible universes which challenged my grip on reality. You make perfect sense: Physics is applying Logic to Nature and should reflect reality and that three generations of 16 particles is most likely the finite number. Thank you kindly, Prof Neil Turoc.

I was so happy to hear that he’s listening to the only actual source of useful information, knowledge and intelligence, the nature, and is even looking for simplicity. My kind of thinking. It tells us that we have to focus more on what we are already focusing on for 50+ years, the (machine) computation and try to find the next big thing through that. Forgetting about the scaffoldings we constructed around it, we could finally rely on our trusty intelligence and the nature. At some point, they will be able to reproduce and even possibly enhance themselves in the form of some kind of artificially created computational structure that follows the logic of the nature (hint: mimicking the barely understood neural networks of our brains to achieve intelligence is a weak conception). By creating and applying a (somewhat) strong intelligence, AND pretty much disregarding the crippling network of our always just partially applicable assumptions and the icing of math completely, we could make the next big step outwards after all these flat decades of my lifetime.

Turok is spot on... if I've noticed anything over the years, it's that the vast majority of people will overcomplicate rather than simplify obstacles. This is especially true of bright people; they're so good at computation that they tend to magnify it rather than reduce it. My intuition is that math and physics are at some sort of computational boundary, and whatever the next step will be, it will have a noncomputational aspect to it.

I agree with Neil about how to manage research, about how to select and manage the human resources in a research organization. I also agree with Neil about the idea of not to "disconnect" so much from the experimental testings (except if you are a pure mathematician). I do not think that much advance will be achieved in unifying gravity with QM if it is not first understood something much more basic: how the classical framework and the quantum framework coexist. That is, the Quantum framework (unitary evolution) and the classical framework approximate 2 different "realms" of reality. Both realms are part of the same reality, but we do not have a satisfactory "model" saying exactly how or when the QM phenomena (phenomena well approximated by the QM framework) become and cause classical phenomena (phenomena well approximated by the classical framework). It is obvious that there exist a "realm" of the reality that is not well approximated by any of the 2 frameworks. Ideally we should try to find a model (predictive theory) for this more deeper realm of reality that should have QM and Classical frameworks as "limit" cases. We have a set of coarse rules that link both frameworks (needed for QM because our perceptual and conceptual background is classical), and that "link" suggests that causality for the new deeper model should not be space-time bound (non locality), more, space-time should not be fundamental, but just emergent from causality. We should investigate this interface between the quantum "world" and classical "world" with a much more open mind and thru experiments. Instead of investing so much in "discovering" new particles or ordering the particle "zoo", invest in solving more basic problems (analogy: investing in finding new animals/plants species vs. investing in understanding how life works.).

All of the so-called particles that make up the standard model table of particles, are composites of these to particles. I honestly believe that it would be well worth your time, to just consider what I propose. Although it is available in a book, I am more than happy to send you a copy of the manuscript. Kind regards, Tony Marsh.

I hadn't heard of Dr Turok although I had a short theoretical physics career in GR. It was fun to experience the era of black holes and general relativity. Now I am retired and am holding a library of abut 200 books on general relativity, quantum mechanics and mathematics. No one seems to want paper books anymore. I'm not sure to do with this library. Any suggestions?

Concrete examples contrasting contradictory equations/formulations from classical physics and mathematics with their non-contradictory counterparts from infinitesimal/non-standard analysis and monadological frameworks: 1) Calculus Foundations: Contradictory: Newtonian Fluxional Calculus dx/dt = lim(Δx/Δt) as Δt->0 This expresses the derivative using the limiting ratio of finite differences Δx/Δt as Δt shrinks towards 0. However, the limit concept contains logical contradictions when extended to the infinitesimal scale. Non-Contradictory: Leibnizian Infinitesimal Calculus dx = ɛ, where ɛ is an infinitesimal dx/dt = ɛ/dt Leibniz treated the differentials dx, dt as infinite "inassignable" infinitesimal increments ɛ, rather than limits of finite ratios - thus avoiding the paradoxes of vanishing quantities. 2) Continuum Hypothesis: Contradictory: Classic Set Theory Cardinality(Reals) = 2^(Cardinality(Naturals)) The continuum hypothesis assumes the uncountable continuum emerges from iterating the power set of naturals. But it is independent of ZFC axioms, and leads to paradoxes like Banach-Tarski. Non-Contradictory: Non-standard Analysis Cardinality(*R) = Cardinality(R) + 1 *R contains infinitesimal and infinite elements The hyperreal number line *R built from infinitesimals has a higher cardinality than R, resolving CH without paradoxes. The continuum derives from ordered monic ("monadic") elements. 3) Quantum Measurement: Contradictory: Von Neumann-Dirac collapse postulate |Ψ>system+apparatus = Σj cj|ψj>sys|ϕj>app -> |ψk>sys|ϕk>app The measurement axiom updating the wavefunction via "collapse" is wholly ad-hoc and self-contradictory within the theory's unitary evolution. Non-Contradictory: Relational/Monadic QM |Ψ>rel = Σj |ψj>monadic perspective The quantum state is a monadological probability weighing over relative states from each monadic perspectival origin. No extrinsic "collapse" is required. 4) Gravitation: Contradictory: General Relativity Gμν = 8πTμν Rμν - (1/2)gμνR = 8πTμν Einstein's field equations model gravity as curvature in a 4D pseudo-Riemannian manifold, but produce spacetime singularities where geometry breaks down. Non-Contradictory: Monadological Quantum Gravity Γab = monic gravitational charge relations ds2 = Σx,y Γab(x,y) dxdydyadx Gravity emerges from quantized charge relations among monad perspectives x, y in a pre-geometric poly-symmetric metric Γ, sans singularities. In each case, the non-contradictory formulation avoids paradoxes by: 1) Replacing limits with infinitesimals/monics 2) Treating the continuum as derived from discrete elements 3) Grounding physical phenomena in pluralistic relational perspectives 4) Eliminating singularities from over-idealized geometric approximations By restructuring equations to reflect quantized, pluralistic, relational ontologies rather than unrealistic continuity idealizations, the non-contradictory frameworks transcend the self-undermining paradoxes plaguing classical theories. At every layer, from the arithmetic of infinites to continuum modeling to quantum dynamics and gravitation, realigning descriptive mathematics with metaphysical non-contradiction principles drawn from monadic perspectivalism points a way forward towards paradox-free model-building across physics and mathematics. The classical formulations were invaluable stepping stones. But now we can strike out along coherent new frameworks faithful to the logically-primordial mulitiplicites and relational pluralisms undergirding Reality's true trans-geometric structure and dynamics.

This is what I wrote. The other was a co=pilot rewrite. There are so many things in cosmological physics to think about. Now spacetime is at the forefront of physics, I think. Space is as we see it the container of all the mass/matter/energy within it. Our observations are based on the movements, motions, and spins of the boundary detections from small to large of those mass/matter/energy distributions. Einstein has shown from relativity, both general and specific, that space(time) warps, twists, distorts et.al. in conjunction with proximity of large masses, thereby creating the warped space for matter to combine in a "gravity well" as it aggregates, leading to star, planet, solar and galaxy systems formations. As well as "blackholes'. It is mass/matter/energy and its motions that we measure. All physics breaks down as to a picture of what was before the theory of the "big bang", while also breaking down what is beyond the boundary of the blackhole itself. The real data that metrics of space(time) has the property of quantum fluctuation where particle pairs are both being created and destroyed, and in some cases creating new real particles that stay in the universe at a rate. "The Hawking Radiation" from blackholes. That the before and after, while the before was all mass/matter/energy that we theorize was injected into a something that became the container that is space(time). While the second, and a subset, was the capture within these warped space(time) wells, enough mass/matter/energy that it closed the warp of space(time) into a spherical boundary condition. Where it would consume at a rate the mass/matter/energy that passed that boundary, we note a "volume change" as the blackhole aggregates more mass/matter/energy within the boundary limits. We note "spin" or non-spin of blackholes. Now think outside the box. There are infinitely many possible wavelengths, practical considerations and measurement precision play a role in determining what we can observe and distinguish. In my thinking, I want to know what was the "space" like before such injection of the "big bang". One has to start "imagining" basing those imaginations on the physics we know. How was the "wall" breached? We talk about the big bang as barely a pinhole, maybe smaller than a Planck Length. Injection, expansion, inflation. Into what? It could be small; it could be large. Did the injection actually create the space it injected into? Was there an energy (back to quantum fluctuations) in the injection space? Is there a quantum anode like and a quantum cathode like to the "spaces"? The bang had to have a source before injection. We could deduce the total energy from the big bang that was injected. It is just we get "dark energy and dark matter" into that equation. We can see what we call a gravity effect from an undetectable source. We see mass/matter/energy expansion where clusters are moving away into expanded space. Our measurements have reached differing rates. We are kind of handcuffed by mass/matter/energy as the tool we use to understand this space we live in. With imagination, with education, a consensus could be formed for this pursui

I agree with Prf Turok’s attitude to clever mathematical theories that require unknown fields etc. Essentially I believe we already have the physics we need. All that is missing from the standard model is the inclusion of the implications of an inverse mathematical proportionality between time and gravity. The greater the gravity the slower time moves so; a view of a cluster of black holes at say ten trillion AU would take longer to reach us than a solitary star at the same distance. As gravity travels at the same speed of light it too would be affected by the slower passage of time. It is these localised time differentials that interact with the universe in a maelstrom of flows from the big bang (The 73% energy) and vortexes in time and gravity that form galaxies, matter over density's etc. This is not semantics. I am saying we are not orbiting a supermassive black hole, I am saying that we and it are the result of external flows from these intergalactic energy/mass/time patterns. M=E/C2 means a lot of energy has a little mass (Thus the dark mass) Further consider the slowing of time in a black hole as time stops everything stops ,entropy, movement ,vibration so by physics you achieve absolute zero. I see the singularity not as a point but as a zone that can grow with the mass of the black hole. This characteristic also explains their ability to continue absorbing. Anything that enters takes an infinitely long time to slow to a stop. Though from outside the Black Hole I suspect that how quickly that happens depends on the mass. Leaving aside what I take to be easily understood: that in the even more turbulent early universe the “Impossibly “ massive early black holes were force fed mass by these dark mass torrents not by their inherent gravitational pull or any change in the given age of the universe. I want to comment on Prof Turok’s comment starting at 16-26 of the video. He is I assume making a reference to “Cosmic Voids” with all due respect the point cosmologists have not taken into account is that as these voids empty their time is flowing faster and faster relative to their dense galaxy shells so it is not an unknown energy we see it is a time curve. The matter further out moves slower so the faster (Time)matter has caught up with it. I have always been inquisitive about cosmology but I have now firmly nailed my colours to the mast. I recommend a topographic time/mass map of the universe ,if we could quantify how quickly time was flowing at the various things we see it could amongst other things explain that the crises in cosmology: The age of the universe. It is simply that there is no one age it depends on what gravitational /time zone you are in and the gravitational past of what you are observing. It would I think show that cosmic strings can be described as visible evidence of venturian patterns in these Energy/Mass/Time flows. I have explained my full theory before so I will not repeat it here but I can copy /paste if requested. Especially cavitation that is central to my understanding.

Sentiments such as this would be well applied in all areas of human society. Thank you so much for this wonderful interview.

Second method to create the point particle: It has in the past it has been theorized that gravitational collapse could have set the stage for the big bang. There is a second possibility in that were one to accelerate any quark using all available matter, and energy in any discrete universe one would have the point particle. as this particle accelerates it's path would form a tighter, and tighter curve following the gravitational curvature of space with the final condition conserving all velocity as rotation around it's own axis. One would assume from current observation that this state must be unstable and that what we currently observe is the result of this instability which is exemplified by a lenticular shape to our discrete universeformed of galaxies spread out in spiral arms with each galaxy on a smaller scale also exhibiting similar rotating structures including spiral arms along which stars cluster, down to solar systems again in which all objects exhibit rotation of individual bodies, as well as rotation of these bodies in orbit around steller bodies. I propose that the second method to produce the point particle while just a thought experiment coincides well with all other theory particularly the notion of a body becoming more massful as it is accelerated which was my inspiration for extending that notion to it's ultimate limit. Of note several data zero out at the moment the point partice is alone in thany discrete universe. First it is both at great velocity either linear along the topography of space, or it is rotating at great velocity, but it is also at rest because it is alone in a discrete universe, and there is nothing to compare it to. Second as it accelerates time slows ultimmately reaching zero. There is nothing for gravity to act upon so it's effect becomes zero. Each discrete universe shopuld others exist are defined as one such as ours that will never share a particle, force, or field. Should there exist any shared particle, force, or field between bodies we define as a universe then they are not discrete from each other. Any discrete universe may containe more or less matter/energy, and therefore this higher, or lower aggragate value would be reflected in the maximum velocity exhibited by any point particle it may form. Via E=MC^2 Matter= Energy = Mass at Velocity. Peter A. Schmitz, Crackpot Extraordinair!

In a material sense, what is this fabric of space? If it were possible to shrink and stand atop an electron, would that electron be hollow? And furthermore, what would you be standing on? My hunch is the ultimate mundane simplicity of the universe is that it just...space. Even the material component of an electron, which can not be broken down further, is simply that the subatomic particles are folds of space....folds in that perceived nothingness we call space. Physics will not reach a paradigm shift or total understanding until we can answer these two questions. What is space? What makes a particle something separate from space instead of something contiguous with space? Intuition tells me that particles are indeed space that is folded. It is the particles that exist in 4 dimensions that we can understand. Space and space time are not 4 dimensional. It is the action of matter in it that shows a four dimensional nature to this fabric of space. Space is a probability field and particles are events occuring within the topology of space. Space is also superdimmensional and isn't constrained by four dimensions. The particles, since they are events within that fabric are constrained by the nature of their existence or the way they are folded. Thus, that is why we have different kinds of particles. These are different propating events that were set in motion....like a loop that can roll down from one end of a string to another, to make an analogy. Space has more than one "side" to it. We are unable to see the other sides because we are made of and using things made of particles constrained to three dimensions. The fabric of space is not constrained to three dimensions and can be as high as 15 dimensions. It is the particles that function in four dimensions only that are the issue. The fabric of space needs to be understood. Once we know all we can about the particles and of energy...and finally can make sense of it all, we will finally see that elephant in the middle of the room... Most of the Cosmos is space. Most of an atom is space. Out of a vacuum virtual particles occur. Zero point energy is real. It is the nature of space that we do not fully understand. But how do we study the void?
