Secrets of the Universe: Neil Turok Public Lecture 

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.

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!

Unbelievable that you can listen to some of the greatest minds in our time. Turok is brilliant.

I wish I could have caught this live. I'm just a lowly butcher, but science is my first and truest love.

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.

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.

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.

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.”

"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 RU-vid to us.

Live long and prosper Turok 🖖

This is what we all being waiting for since The Astonishing Simplicity!

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. 🖖🌠🌈🛸🦄

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.

A privilege to sit in on this lecture from home. Thank you.

My main man Neil never disappoints ❤

The best lecture yet🎉

Always a fenomenaal lecture. Good to know born South Africans are doing well in the USA. Dearest Regards, From South Africa.

Kudos, thank you Neil and thank you Perimeter

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.

Finally another public lecture. I've been missing those a lot! And then it's even with Neil the legend Turok himself :D

I was watching this during the Rugby World Cup Final to calm my nerves.. We won Prof Turok! 🇿🇦

Very interesting ideas. Thanks for the lecture.

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)

Turok begins at 4:28

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.

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.

I still can't understand what he's talking about, but what he's talking about is much more easy to follow and to grasp than what the PBS guy or Sabine Hossenfelder are trying to tell us. It feels like I can almost understand it. 😀 What I feel very positive about, is that he got rid of that silly Inflation idea. What a relief! 🤗

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.

Enlightenment indeed ! I am going to study this further, I really think he's cracked it...

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!

simply beautiful, elegant presentation

I have been waiting so long for this. Thanks Neil and PI. ⭐

Learning about reality makes my heart soar.

Physics eases my mind from the chaos that is life

Excellent!!! This man is way too smart. 😮

Canada does this type of stuff very well. Its very well done.

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".

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?

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!

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?

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. ❤

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?

This point was not the start of the big bang but the expansion of the universe by mass equalling gravity of space and with centrifugal force expands.

Neil Turok I.S. (Infinity Squared) right on "The astonishing simplicity of Everything". Neil Turok, you have shattered the human perception of cosmic ceilings.

I really enjoyed his apresentation.

Beautiful.

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.

"Maybe we have time for one more quick question. Is it a quick question?" - "Yes. […long monologue…] What is existence?"

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.

Thankyou for your video at last

its interesting that ancient Egypt has a story about creation and where “light sees its own shadow.”

Love Dr. Turok

I love this guy talking

Brilliant talk

Most powerful application of cancellation I've ever seen. He gave us permission to remove the Nutrino L's!

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

Neil has it figured out!

THANK YOU...!!!

Thank you 👍

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.

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.

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!

Turok, you rock!

Anybody other Hitchhiker's Guide to the Universe pick up on the fact that the number 42 is apparently easter-egged prominently as this man answers the question of the Universe? I mean, I guess it was 42/100 but I grade on a curve 😂

Very interesting!

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)

It's always NOW => every day is Orientation Day, first-class of everyone's career throughout life in pulse-evolution.

I admire so much whoever understands 10% of this presentation

Neil turok is the man 🎖️

Turok is a great Vulcan star-trek character name 👍

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...

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.

Marvelous

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

Funny: someone went to a lot of trouble to intentionally name the place PI only to have folks “shorten” it to the four syllable perimeter.

Realy I like this video its interestyng

1:20:20 This is the topic that fascinates me. Could anti matter be rushing backwards in time thru the singularity and out the other side in the mirror universe?

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

The question about how we observe the BBT is "bang on" Relativity of 1-0-infinity wave-particle coordination-identification positioning.., holography.

I feel like the root cause of existence is something to do with cycles. Like the way complex numbers cause periodic graphs compared to regular numbers.

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).

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. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pMCnT8ZqGkA.html Can’t post the link to the book here directly due to youtube’s restrictions.

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?

"Look at the large chunk of data - see what fits - [our narrative, and YOU] learn from that!"

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?

Awareness is the only constant of all experience what could be more fundamental to reality than that? Awareness is known by awareness alone.

I did not understand much but I think it was good for my neurones connection building anyway😂

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

Gee-Whiz Propeller-cap KID-Science in its highest expression. Modern Theoretical Science.

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.

Spirituality is when you connect to the other side then your side will be a little bit brighter

C and D are your roots and your production capacity

Cosmology is under control. 💪🙌

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."
