- How did the universe begin? How did it evolve to what we see now?
In his Perimeter Public Lecture webcast on October 25, 2023, Perimeter Director Emeritus Neil Turok shared his insights into the basic laws of the universe and their surprising simplicity - including his latest work on an alternative to the cosmological inflation model.
Turok is an internationally renowned cosmologist who has collaborated with luminaries such as the late Stephen Hawking. He is the Higgs Chair of Theoretical Physics at the University of Edinburgh, and holds the Carlo Fidani Roger Penrose Distinguished Visiting Research Chair at Perimeter.

I spend too much emotional capital listening to the problems of our political landscape. I come to these videos of lectures given by rational, intelligent, intellectually curious people to remind myself that they, and I hope I can say we, still exist. I hope there are enough of us engaged enough to turn the tide of the irrational mobs that will, if they can manage to do so, overrun virtually every intellectual pursuit left to humanity.
What a beautiful post.
Thank you 🙏
you're an emotional capitalist? nice!
Very little return on that, of late@@egay86292
Lovely!
Agreed. I'm glad to see Neil Turok again. I love his lectures.
Besides his obvious profound intelligence and curiosity I find Prof Turok to be equally humble and human. So many of the world’s other notable theorists are just so inaccessible and seem insulted when their theories are challenged.
Whether or not Turok is on to something this was a masterclass in presentation and exposition. The students at Edinburgh are so lucky!
I felt the same, it is immaculate, an example of how to present information. A question though, new to this: for e.g. 11:18s the Cosmic wave background spectrum, Boltzmann curve x-axis is depicted with frequency, whereas the normal (and yet identical curve I find) show x-axis in wavelength. How could the 2 curves be identical when wavelength is the inverse (opposite) of frequency?
Great presentation.Thank you Prof Turok

Unbelievable that you can listen to some of the greatest minds in our time. Turok is brilliant.
Yes, with all that is available via the Internet there really is no excuse for the unabashed ignorance that pervades some Western societies.
@@mitseraffej5812 I live in the Southern United States, i know precisely what you mean unfortunately. The silver lining in the situation is that the most ignorant tend to be the loudest, whilst the rest of us are just scratching our heads. Critical Thinking 101 should be a mandatory class in high school. Unfortunately the powers that be really love the uneducated. Gee i wonder who i could be talking about...
I quite liked Turok 2 on N64, great game!
nonsense science is not near to answering the big questions there is no progress just speculation you might as well ask a sci-fi writer
Love these videos. A lot I still don't understand, but whenever a little piece falls into place, I am so happy.
Mind blown. Thank you for making this available for us. What a wonderful opportunity to have access to the worlds greatest thinkers and researchers.
Somehow I feel as if we step back far enough, we would see our life emergent from the flotsam of increasingly complex energy waves. Life is freaking amazing.
Calm down Dear!

I wish I could have caught this live. I'm just a lowly butcher, but science is my first and truest love.
Why is being a butcher lowly? My grandfather was a butcher and he was among the brightest men I’ve known! Besides we all have to eat! Your job is important!!! ❤❤❤
*Whose* science *of_ what*? Why the Uriah Heep act?
What about knives ? Fare thee well.
Me Indian meditation teacher said this: 'Why not ? A butcher can be a saint.'
Fare thee well.
Neil Turok, future Nobel winner for Enlightenment, aces it in his last answer; reaching so high effortlessly, he can't but take the prize. Thank you for catching me up over the past fifty years. Perimeter is fortunate to have captured a place in your heart. I'm sure you'll be back one day with more stories from the event horizon.
"It would be called Enlightenment." Nice! Distinctly fitting summarization & clear conjunction to the acutely mind-blowing cliffhanger of a lecture. Mr. Turok gave with the Simplicity of Everything at PI in 2015 as Director.
I trully love such smart and clever people - thank you for bringing this excellent talk in UA-cam to us.
This is what we all being waiting for since The Astonishing Simplicity!
Turok: “It tells us its secrets.” Recall Shakespeare’s lines: “And this our life, exempt from public haunt, finds tongues in trees, books in the running brooks, sermons in stones, and good in everything.”
Amen 🙏

In the formula F=ma, a has a time variable which means F = 0 when time = 0 and Force can not be calculated unless you provide time duration. The parameter a Acceleration is due to the Gravity and Gravity has a set vector / direction, 0 to 180 degree, in other words there is NO Acceleration if there is NO Gravity, and in Gravity direction and Time needed. Force is 0 (zero) unless you give a non zero time.This is what scientists have been hiding and the space time scam is to explain a flawed formula using the gang leader einstein. E=mc2 is also False since you can change the constant 2 to 3 or any other number, it has no effect because E has no Unit. Also all the formulas mentioned as the successor to E=mc2, has the Time variable with the value 0 (zero) which makes all the calculated Forces, Energies and Vectors Zero. Additionally einstein never wrote and published any of these formulas and no other scientist wanted to claim Fallacy.
Shakespeare should have said books in trees and tongues in running brooks. He was incorrect. Thanks for the quote.
To-morrow, and to-morrow, and to-morrow,
Creeps in this petty pace from day to day,
To the last syllable of recorded time;
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life's but a walking shadow, a poor player,
That struts and frets his hour upon the stage,
And then is heard no more. It is a tale
Told by an idiot, full of sound and fury,
Signifying *Nothing*. Also courtesy of that esoteric school that hid behind the name Shakespeare.
This tab has been sitting in by browser for 4 months, I'm glad I finally watched it. I cannot tell you how relieved I am to learn that Turok finally has cosmology under control.
Finally another public lecture. I've been missing those a lot! And then it's even with Neil the legend Turok himself :D
My main man Neil never disappoints ❤
As always Neil Turok provided a very informative talk. My only criticism is that the shots of the audience during the talk were rather distracting.
A truly wonderful exposition. So profound yet also very accessible. It takes a true master to make it look this easy. 🖖🌠🌈🛸🦄
A privilege to sit in on this lecture from home. Thank you.
Live long and prosper Turok 🖖
The best lecture yet🎉
I love this conversation. I would love to understand how long cycle gravitational waves can be explained within this theory. In my perception. I always figured it never become as a singularity and that the wavelength of light stretched over time, creating the red shifts and make galaxies appear to be travelling away when they weren't. It's been a long journey of trying to figure it all out.
Kudos, thank you Neil and thank you Perimeter
Always a fenomenaal lecture. Good to know born South Africans are doing well in the USA. Dearest Regards, From South Africa.
Yet - firstly - human being - like all of us. Muddling through - with this meaning - nay, truth quest.
Also from SA - now in Germany and imbibing spirituality - from Indian meditation. Hee hee.
Fare thee well.
Here is hoping - that other thinkers and viewers - grant enough space - for Prof Turok - to continue his original thinking.
To bring clarity - in his way - to the thought - in physics research.
In simplicity - it is quietly apparent - that essence is realised. ( Hint from Raja yoga meditation)
Fare thee well.
I waited new Neil Turok video for like a four month and I smashed that link 20 seconds after it became available. Since I heard it first I trust Neil approach much more than I trust string-theory-multiverse-inflation bad infinity. I believe Astonishing Simplicity is actually the way.
4:53 talk starts here
Edit: Could have needed bookmarks to jump to the new stuff (edit: note to self: jump to 41:26 ; the real bomb gets dropped 57:56). Pretty slow start; even a bit tedious to watch the beginning.
19:30 our model of the universe: Lambda CDM
22:02 promises minimal theory: starts talking about critical behavior and phase transitions; (foreshadowing)
28:09 promises easy solution to the Big Bang; (more foreshadowing)
34:00 smallest and biggest lengths you could even theoretically ever see: introducing Planck Length and Lambda Horizon; (at Planck Length a photon of that wavelength would form a Black Hole, so light can not escape; at Lambda Horizon distance, space expands faster than c, so that this light can never reach us)
38:13 “These are all the laws we know.” - reiterating that maybe there are no more “new particles” (- even more foreshadowing)
39:27 The Standard Model (insert usual picture)
40:31 Three Generations of Particles, but why? (- more foreshadowing)
About time we came to the good stuff (- the things I hadn’t heard before)
41:26 right handed Neutrinos (Seesaw mechanism) as good candidate for Dark Matter
43:18 predicting the cosmic abundance of right handed neutrinos via CPT-symmetry; the Big Bang as a mirror
46:29 so: what if right handed Neutrinos are Dark Matter? A stable and heavy right handed Neutrino would imply the lightest normal, left handed Neutrino to be massless! There are measurements underway to constrain the mass of the Neutrino.
48:32 nice side effect: Penrose gets his “conformal Big Bang”
51:47 claim / argument for why the cosmos is as it is: entropic reasoning
57:56 “NO ADDITIONAL SMOOTHING OR FLATTENING MECHANISM IS REQUIRED.”
Turok pulling a UNO Reverse on the Inflationists. A true Laplace-vs-Napoleon-move: ”I had no need for this hypothesis, Sire.” 😂 Mic-Drop-Moment
59:01 the problem of mm-scale-gravitational-wave-detectors
1:00:38 The origin of the three generations and structure formation: introducing 36 zero-dimensional-fields to get rid of infinite vacuum energy
On second viewing: this seems a little light on the details…
P.S.: You plug in a measurement from Particle Physics / The LHC into your formula and receive a value that equals a measurement from Cosmology / The Planck CMB satellite to almost two decimal points. - How does that tell me anything about how you chose your formula? Maybe you chose it in a way that it fits? You introduced 36 new constants of nature for this?? How is that progress? How is this the end of the talk?? This should be the beginning of a talk! Does this count as an explanation? - You could have produced a rabbit from a hat like that, for all I know! Are you sure you didn’t just put in the rabbit in the first place? Forget all the hand movements and the name dropping: what exactly did you do? I just have to admit that I did not understand a thing.
I have been waiting so long for this. Thanks Neil and PI. ⭐
Definition of Theoretical Physics. A continual guesssing game of how things are,tested, accepted or rejected,including many fudge factors to make the maths work. Though not being able to understand most of Professor Turocks I really appreciate that throughout his talk it is punctuated with "maybe" or is "just theory".
Turok begins at 4:28
👍
Very interesting ideas. Thanks for the lecture.
He is definitely on to something, I have always asked why everything looks the same a egg in a pan a hurricane a solar system a galaxy a tornado the pedals on a flower the spiral of shells and so on it says the geometry is simple at the core. Wolfgram said that very simple rules can lead to complex systems.
simply beautiful, elegant presentation
According to the supercomputer Deep Thought the answer to the question of life, the universe and everything was 42 (in Douglas Adam's Hitchhikers Guide to the Galaxy). At 1.05.12 Neil says the critical exponent from Cern and extrapolated becomes 42!
Canada does this type of stuff very well. Its very well done.
This is partially thanks to the fleeting success of the Blackberry. Watch the movie: en.wikipedia.org/wiki/BlackBerry_(film)
Neil Turok I.S. (Infinity Squared) right on "The astonishing simplicity of Everything".
Neil Turok, you have shattered the human perception of cosmic ceilings.
Top notch, thank you Neil and PI. Now to ponder and chew over what I've learned over some snacks. Good science and snacks, a cosmic must!
Learning about reality makes my heart soar.
I get that it seems simple to Neil, but honestly, even the stuff I thought I understood ok, when he explains it, I realize, wow, I REALLY don't understand this. No shade. I just think he understands these things at a level I'm nowhere near.
(...going to replay it a bunch more times to see if I can get it a bit more)
Listening to this repeatedly is the right thing to do. I used to work with a guy who could repeat sitcom lines because he watched them repeatedly. We CAN pick how we wire our brains. Even if we don’t start out in life knowing that. What happens to FAUX viewers. They become what they consume.
Enlightenment indeed ! I am going to study this further, I really think he's cracked it...
I live in Oxford England. Thank you for this lecture by Neil Turok. I have mentioned this to many of my friends.
where you live has to do with what?
@@bryanpinto4051 Nothing at all it has to do nothing at all
That's the magic of the past few decades' technology genius, making it now possible for the entire planet to watch a profound lecture in the middle of Canada soon after it concludes. It's been likely the best ten hours I've spent in the last fifty years. Professor Turok presents the magic so well, it seems intuitive, simple, as it merges into our current view of reality. Yes, we will "understand what the hell is going on" as Neil jokingly summarized Physics' quest.

There are many interesting and vital - nuances - to the reality and especially - the Real Being.
Trying for this meaning - is itself - so rewarding.

"Maybe we have time for one more quick question. Is it a quick question?" - "Yes. […long monologue…] What is existence?"
Physics eases my mind from the chaos that is life
I tried, but felt I could not grasp most of this lecture. I watched it again and felt utterly stupid. So glad there are people like Turok to do my thinking for me! I forgive him for making me feel so mentally inadequate. ❤
Here's another takeaway... maybe the lecture was written for a selective audience and not for the average, interested layperson. I conceptually understood most of it, but none of the mathematics and I still fell asleep halfway through. The most interesting part was the very last question - which was answered basically with a "we don't know".
Hi, Do not feel intimated by these lectures. Give your self credit for sitting through this. If this lecture re sparked wonder and curiosity like you had as a child, That is a good thing!
Love Dr. Turok
Thank you Neil. Very cool 💛 41:10 is the generation puzzle about the bi-direction spiral of the sphere? 44:03 Each human is born with a piece of that copy. Every culture and interpretation of their copy is so important to balance with how we govern and treat each other. 1:02:32 Isn't this why we have a reciprocal relationship with the moon?
37:10 Love this talk. Just wanted to add that the Higgs boson can not be seen directly, but only inferred from its decay products.
I'm loving with you Neil, you're amazing human being.
Just Wow. Thanks Neil, amazing ideas. Wondering if this theory has a name yet? Also, just a guess, you mentions a relation ship between having 36 dim0 fields and the 2 groups of 6 particles, seems like those fields might give the particles their 3 dimensions, or something to that effect.
yeah, but more like two groups of two, because each group has two extra that are heavier, e

His model has a taurus in it. The "Turok Taurus Theory"... or "T^3" ... ?
Most powerful application of cancellation I've ever seen. He gave us permission to remove the Nutrino L's!
Beautiful.
It's almost like Turok has explained a reduction in soup into its constituent parts that makes the whole dish possible and tasty. No need for magical cooks. Just the ingredients. I like that concoction much better than the fanciful explanations of imaginative, clever theorists. Just a great soup recipe that makes sense. Now the last question was about the cook in a roundabout way. Why did it all happen? I say, why not?
I really enjoyed his apresentation.
its interesting that ancient Egypt has a story about creation and where “light sees its own shadow.”
THANK YOU...!!!
Thankyou for your video at last
Brilliant talk
Can someone explain to me why I'm addicted to listening to these geniuses even though I haven't the faintest clue what they're talking about?
Turok, you rock!
Neil turok is the man 🎖️
37:10 Only through Indirect detection, which means that the Higgs boson is not observed as a single particle, but as a combination of other particles that result from its decay.
I admire so much whoever understands 10% of this presentation
Thank you
I think there is a typo at the 46:35 mark. Planck mass is 5 x 10^-8 kg (the minus is missing from the 8).
He was saying 5x10^8 proton masses - as in half a billion - which I think means these neutrinos are less than a thousandth of the Planck mass.
@@andymccracken4046 You are right. I thought he was talking about Planck mass here which is 5xe-8. My bad.
Science and the universe are something too sublime for me. Thank you for letting ignorant people like me see more of the universe. I really like this channel
I love this guy talking
Thank you 👍
Neil has it figured out!
The Higgs boson can decay into various combinations of particles, depending on its mass and the probabilities of each decay mode. Some of the most common decay modes are:
Two photons (H → γγ)
Two W bosons (H → WW)
Two Z bosons (H → ZZ)
Two bottom quarks (H → bb)
Who knows, maybe there is no decay in the absolute sense.
The useful information here is that the emitted particles emitted are paired with antiparticles. Though your antiparticleschave not been identified.
Breaking the breaking of symmetry shouldn`t have been seen as so far-fetched. So, the Universe cannot tell left from right in the end, huh. Or in the beginning. The way he sold it (virtually flawlessly) made it sound like it solves more problems than it causes from the get-go. Quite a feat already. Cheers!
"Look at the large chunk of data - see what fits - [our narrative, and YOU] learn from that!"
The question about how we observe the BBT is "bang on" Relativity of 1-0-infinity wave-particle coordination-identification positioning.., holography.
Is the point of singularity non-dimensional? And, if not, wouldn't the two sides of the mirrored universe actually expand into overlapping with each other? If they don't overlap each other, then are there gaps between the two universes that also need to be explained?
15:30 is a very inadequate description of 'ultraviolet catastrophy'.
Cosmology is under control. 💪🙌
I did not understand much but I think it was good for my neurones connection building anyway😂
Realy I like this video its interestyng
I am rather more attracted to the idea of dark matter simply being nanometre dust particles, and dark plasma in the form of hydrogen ions. We live in a plasma universe, and Occam and Newton agree we shouldn't introduce anything new without just cause. If space is has a lot of dust particles of just a few atom or two in size, then high energy photons could hit them directly raising their temperature to thousands of degrees, which - added together would explain what we call the CMB.
Then there is the issue of redshift - which we do not fully understand, and it seems likely there is at least one unknown factor which causes light to lose energy over distance. And if that is true, then dark Energy will simply disappear in a puff of inevitable logic.
For, just as LaPlace said to Napoleon, "Sire, I had no need of that hypothesis."
Very interesting!
Marvelous
Plancks k which looks a lot like Newtons G equation. But that curve is a common damping curve used in many areas of science. Sound getting slightly then quieter for example.
Hello from Kazakhstan! You are familiar with Michelson's experiments. (1881) and its improvements for the discovery of gravitational waves (2015) - And that's only 50%. It is possible to continue this experience; Use "from the gyroscopes two non-circular spools of optical fiber." This device, which is located inside the car, measures: inertial speed in a straight line. (the device does not record the movement of the satellite in orbit). I can share ideas for joint invention
Each individual water drop in the body pushes and transfers the energy while changing itself. Like 1 hitting 2 and it transfers energy and not only moves in direction but moves in an evolution. It’s more apparent in macro things because we see it easier. The cascade is why it’s so fast but seems so slow now. We can see the patterns because we are those pieces in a form/pattern. We are grown in real time because of the cascade and patterns of growths in the brain. Cells being grown from the input of reality through the senses in a pattern that connects to the other senses patterns like touch or smell combining. The patterns are consistent and are seen in math, geography, and in life itself as well as the spirals in the universe. It’s kinda weird to think about if you think it’s weird so don’t think it’s weird and try to understand before sending hateful comments. Thank you. We grow in tandem with reality just as our cells and us grow and not just grow as in make bigger but shift in form like a butterfly, superpositioning.
uau one lecture practically explains every cosmological and quantum mystery there is...
Neil has a sane look at science, physics and the cosmos.
I am tired of hearing about string theory, multiverses, bubble universes and infinite inflation.
Well said....
Yeah. Pretty much what I thought.
😅😅😅
Seriously, folks. You got simplicity, beauty, symmetry.
I almost nearly sort of get it! 😊
31:25 the spread is there but you gotta look at the changes made over the span of the spread, the patterns of change within the spread show you something similar to evolution/change over time.

Why can't there be a Doppler effect from these particles?
In the description of this short video there is a link to a book that proposes a new model of the universe, describes its shape, structure, the mechanisms of its birth and evolution. ua-cam.com/video/pMCnT8ZqGkA/v-deo.html
Can’t post the link to the book here directly due to youtube’s restrictions.
The last gentlemen's question seems to hover around Lawrence Krauss's answer to why is there something rather than nothing which he argues (if I understand corredtly) because "Nothing" is unstamble. "Nothing" being otherwise totally empty packets of Planck-level space which are linfinitesmally energized. Further inquisition leads to speculation with regard to First Causes which Krauss argues converts physics to an environmental science.
I have always thought about, as above so below and the fact that the universe is mirrored in atomic level of matter. What has always resonated with me and my research is the fact that we were taught that the universe is teetering on a knife edge and if one little factor had been out of harmony, the universe could collapse. Extrapolating on this, I have always reconciled the model of the universe as more of a result of SUBLIMATION i.e. Going from a solid directly to a gas state or sometime soon, a gas to a solid. The universe then would be more of a cyclical nature of phase change in my opinion. What do you think?

It seems actually very reasonable that there are gravity that attract mass and a force that disperse mass in analogi with electric fields. So there may be a connection between these ? Gravity is compressed space where time goes slower and dark energy is diluted space where time goes faster. Now we just need an equation and a Nobel price
Awareness is the only constant of all experience what could be more fundamental to reality than that? Awareness is known by awareness alone.
Talking about mysteries. Awareness like the Universe are. I think it is beautiful that we can marvel about mysteries.
Is A.I heading for awareness ? ? Could you argue: Awareness is an attribute of the Universe and therefore that the Universe is self-aware ?
Great talk. Pity about the basic problem. How to explain the origin of the Big Bang. Inflation Theory, hmmm, not bad but it is still lacking something. It is not smooth, it just doesn't quite gel.
Still Prof. Turok shows a great ability to think outside the box (sorry about the pun). His discussion with Dr Brian Keating last year demonstrated his realisation that some new insight is required to smooth out the complications that have been introduced over the last 20-30 years. String Theory et al.
I will stay tuned to hear futher developments
Logic, make sense in every angle
