I can listen to this brilliant fellow lecture for hours and hours. He gets going and its a whirlwind of genius. Love it. Thanks for the upload ❤

link to the next day's lecture Space-Time, Quantum Mechanics and the Multiverse (Nima Arkani-Hamed) kzfaq.info/get/bejne/fNiEpMKeltawqmw.html

I like the assertion: give a professor enough time, food and graduate students and they can figure out anything. Even though I can't follow much of the math, I greatly enjoy Nima's talks

Nima makes male pattern baldness look good - keep pioneering, bro

I can't believe you broke it down to a level that understand. Your interpretation step by step was pretty much spot on. Quit it I hear your inner voice saying I know Genius level right... Lol just kidding around. Thank You Dr.

Finally we got somebody with all the complexity in his head and can tell so easily.

Once again. Thank you for opportunity to see/hear.

I watched a "free" documentary on Time on KZfaq yesterday. It claimed that "The weak force is Gravity," which is misleading. I felt compelled to correct the publishers by explaining that gravity is neither a weak force nor a force at all. It is actually the consequence of mass interacting with space, creating a gravity well that causes our planet to orbit the sun. The smallest possible black hole that can exist is limited by the Planck mass. This can be calculated by taking the square root of the reduced Planck constant multiplied by the speed of light and then dividing by Newton's gravitational constant. This mass is approximately 10^-8 kilograms. If gravity were stronger-if Newton's gravitational constant were larger-then it would be possible to create even smaller black holes. You get what you pay for, has never been more true.

Brillant talk!

You could always use a little crazy glue to adhere the pencil to the table. Higher energy levels lets go. Nice presentation.

On topic, "There's no wrong question or answer", if the context and content of relevance are mismatched, ie in the "Not even wrong" conceptually, (Socratic) philosophy. For those who know how a Laser is "pumped" before reflecting the nodal-vibrational, orbital-orbit states around the crystalline line of bonding, the ubiquitous-universal superposition property of frequency aligned wavelengths, Reciproction-recirculation Singularity e-Pi-i fractal function, exceeds the tuned length of the device and emits a pulse of the reflected wave. The same mechanism applies to the Universe in every detail of its Being. You can figure it out, if you are willing to trust in your own included self in this mechanism. Ie it's all about tuning and timing, that is it, that is all.

Thank you for sharing this video!

So where is that second talk he mentions at the beginning available online?? Not the Q&A video to this first talk, but the one he says he's giving on the next day. Anywhere online?

I have to admit that current fundamental theories do have a kind-of epicycle feel to them. I'm sure there's something really important we're missing.

The comments here are idiotic. Great lecture.....

Great talk! Wish there was a link to the discussion he mentioned repeatedly.

Fantastic talk. v good speaker

Hey! Good camera work too!

I don't understand the 'Delta Observed = Delta Classical + Delta Quantum' argument (at 24 mins); which seems to be a central piece. He seems to be arguing that the 'Delta Classical' term subtracts120 decimal places (as a kind of constant) in order to give us 'Delta Observed = Delta Quantum'. But surely 'Delta Classical' has to subtract 120 orders of magnitude (in terms of a CONTRACTION of space-time) instead. IE. to do away with the 120 orders of magnitude of expansion that is unobserved, though predicted. What am I missing? Any comments gratefully appreciated. Nima, you out there mate?

The greasy enemy of life and Being is Time,real or virtual they replace in science what in morality we will call Good & Bad

I do believe in the MultiUniverse Model, especially in the version where their is only one universe.

Thankyou

Nima and Donald Hoffman should talk soon

Well... It is 2021. Have we got big new principles or a bigger paradigm?

I cannot find part 2 of this, does anyone have a link they can share please? I see some short Q&A from this lecture but I am more interested in his personal take on what's "going on" that he mentiones would be in part 2.

great great great !

His slides look like they could be from a Wes Anderson film.

The spin 2 is in black as if it was confirmed, but isn't it purely theoretical?

i dont get why so many scientists misunderstand the anthropic principle. Finetuning of natural constants has nothing to do with cosmology. All scientists do when finetuning, is to look at how delicate and complex physics became as a description of our world. change the language slightly and you will end up with nonsensical jibberish. it doesnt mean, that this nonsensical jibberish actually exists anywhere out there. i personally spoke to prof. Oberhummer in 1998, who introduced the anthropic principle. he wasnt fond of this misuse either. it just shows how frustrated scientists are with their role in society, seeking deeper meaning of their work than there is.

There has been no greater promoter of Einstein's, General Theory of Relativity, Special Theory of Relativity, and the Photoelectric effect than Brian Greene. Now Nima has made the assertion that "space-time" a key component of General Relativity does not exist beause it is completely at odds with Quantum mechanics. Maybe then Nima and Brian Greene should discuss their different perspectives on a publc forum for the rest of us.

I keep wanting to brush his hair back and putting it into a ponytail or bun. That said, I love his lecures and this subject matter (and all theoretical physics)! : )

is anyone else here listening to this genius hoping at some point to understand something? 😅 i keep trying so that maybe my subconscious will make sense of it. 🤓

Einstein: Space and time are just aspects of spacetime and have no independent existence. Arkani-Hamed: Spacetime doesn't exist except as an "emergent approximation" of a more fundamental reality.

I believe you forgot a simple equation: as above as below. Now found Higgs, Quantum Computing doesn’t sound weird to you? I would be worried about finding something that gives me that Higgs process. We’re fucking crying for two bits. 😂

Devolving into multiverse explanations is so disappointing. I tend to think folks like Penrose and Ellis have the better attitude on such questions. But I just love the way Nima links the small and large scales. Few other physicists bridge these gulfs. You could say Susskind and Maldacena do, but Juan's talks are so cerebral they are not so entertaining. So thanks Nima. His hair is receding because his brain is emitting a lot of radiation. Only trouble is, like Feynman, after hearing Nima talk you think you could almost do some bleeding edge theoretical physics. Doh! Turns out to be a little tricky!

Reminds me of "Just Six Numers".

The universe is big so that big macs would fit in

Why is the universe big? Maybe to accommodate all the big elephants. : )

Extremely interesting and important lecture on the front line of physics of fine tuning and the Standard Model, by NIMA, who is a rare breed who dwells in finding the little known and rarely admitted reality of the anthropic principle, leading to unearthing the mystery of fine tuning, intelligent design and the role of the universal probability wave function, governing everything in the universe, from photosynthesis that produces food for all plants and activates our five senses, our brain and all our cells employing quantum computing capacity using entanglement, tunneling etc., even the black holes are quantum phenomenon. Fine tuning (FT) and intelligent design (ID) have no explanation in physics. However, phase transition of non-life matter to life (due to self-organizing property of matter), is. Similar phase transition can be imagined to have self-simulated conscious observer that collapsed the Feynman's quantum field into fine tuned particles, like in the double slit experiment in QM, implying intelligent design that created life and human consciousness, with perfection and with probability one, implying divine purpose. 'A priori' nature of mathematics, according to Max Tegmark, implies 'the mind of god'.

Uh um

If your unique consciousness doesn't possesses adequate specificity to select for a unique string theory universe out of the 10^500 possible in the Multiverse, then you're living in someone else's universe. 😃

Who are the many people that say space time doesn’t exist.

The new field study of the-nE state at 273'15. Is that it is produced by the M.Q.D., not the Q.G.D. A inverted magnetic field state. Q.G.D. is the product.

Uncle CC here! Let Uncle CC help you balance the equation. from C.C. Arshagra, creator of the I Do Not Know Show, The Divide & Conquer News Report, and Dear Dead People with uncle CC. Also an awarded poet, publisher, and multi-medium artist.

The three dimensions is Micro- Medio- and Macro-Cosmos, the Life-Unit-Principle, and the Perspective-Principle plays a major role in this question.

'universe seems impossible' - indeed, when you think of it, nothing is possible but 'nothing' can be expressed as '0' and '0' can be a result of maybe an infinite amount of equations; I'm probably wrong

Extremely idiotic comments... Beautiful lecture and the paper published on the same day thank you..

That thing has lots... and I’m sure there might something hiding but well... you know how it goes.

We have to remove the reference point

It should be called the noothropic principle; then "relativity" would be a mic drop. ... Multiverse/mass/relativity... hmmmm.

"ukay?"

only string theory can be done in room and the results will be similar to getting magnetic monopoles .....bullshit...

This isn't a coding error, otherwise it would be _consistently_ wrong across all counties. It could be an input error -- either user error inputting the data into the app itself OR, perhaps, if they're manually taking the data off the server and entering the data by hand into some other parsing program... similar to a copy and paste error. In any case, the inconsistency was caused by human hands. If these inconsistencies turn out to _only_ negatively affect Bernie and Warren (the only progressives), then it's _definitely_ done on purpose.

“and a threefold cord is not quickly broken” (Ecclesiastes 4:12)

I'm bailing at 6:50 but I have to comment that, from a philosophical perspective, we are locked in a room where we can't directly observe the universe. (See epistomological skepticism) So we do have to ask the question Does QM and Relativity describe something that really exists? But that's not what this lecture is about.

Nima, lay off the caffeine, dude!

Tripe. A masterclass in incredulity.

10 to the minus 120 degrees... Proceed!

Tomorrow tomorrow tomorrow... The sun'll come out! I'm so not paying attention 🤤😵😕 "vacuum energy equals zero..."🤯

This is not what the Higgs field is or how it works... the Higgs mechanism was specifically proposed to explain the surprising mass of force particles (the W and Z bosons). It is not responsible for the mass of the electron, nor does it have a mass on the Planck scale. It is actually pretty distressing how mishandled the Higgs was, because it means there might have been lots of other wrong things that I don't know enough to spot.

I don't understand how saying "the universe is big" can have any meaning. Big compared to what?

N.Asadi: I can bet that if Nima Hamed would go to Iran to give a speech, he would be put to death by the holy mullahs for not mentioning the prophet Muhammad!

i already found out how eternal universe works.

its big because my ego is in it and its almost infinite

i think, i have a answer for you.

And this whole idea that human beings are irrelevant to an uncaring universe is just negative thinking. It is more likely that consciousness exists as higher dimensional vibrations in a vertical system of of quantum wavefunctions. The highest layers are the easiest to express consciousness because expressing consciousness takes less energy, less effort for a consciousness.

Maybe you should check your emails... might like what I’ve sent you.

He walked too much. Distracting….

This is God speaking: I fine tuned it to be just enough to tease and torment y'all. Going back into hiding now.

It would drive me mad if I had to work with this guy. He would have to be in an office in the deep basement.

I don’t understand the opposition to deshitter space. It seems to me important for all of us for the process of getting rid of waste materials in our bodies. After all, how much spacetime would it take?

The whole thing is a simulation and the master programmer is called God.😮😮😮😮

Let's face it, philosophical cosmologists are not describing the simplest and best explanation why anything is here at all. The best explanation is my explanation. Consciousness exists along a vertical spectrum, from most dense (in the spacetime continuum) to increasingly higher levels of consciousness which exists within wavefunctions that are increasingly easier for consciousness to express itself.

I'm sure this dude has a beautiful skull. He needs to just let go.

I’m so sorry but he’s not a good explainer

What exactly has this guy achieved for the last 10 years? All his videos are the same thing... and on top of that he never uses proper slides, just handwritten ones!

He should so shave his head

screw cosmos. he needs to hit the gym. he doesn't have any muscles. look at his arms. yes he is a very brilliant physicist and thinker. but he needs a healthy body too.

More talking than substance.

His hair disqualifies the entire lecture.
