Lecture from the mini-series "Multiverse & Fine Tuning" from the "Philosophy of Cosmology" project. A University of Oxford and Cambridge Collaboration.
I quite enjoy Nima's insight. For those who are interested in some of his work he is featured in a documentary about the Higgs on Netflix called Particle Fever.
+digibu hahaha One day some one will mathematically prove that there is a correlation between being highly intelligent and not knowing how to look handsome hahahaha. This guy is like a god in theoretical physics and quantum mechanics so I don't see myself in a position to criticize him in a million years. hahahah
I realize this is from 9 years ago, but I don't understand why the CC can't be 20 orders of magnitude smaller than the critical value that allows anything to exist (23:00).
As a graduate student in theoretical physics, I have always had little patience with string theory and its holography and multiverses, as often heard from the pop sci literature. This lecture finally convinced me that multiverses and holography are at least conceptually valid, perhaps even desirable, options to consider.
Pretty standard stuff today. Bet you have a class at University there. 🙃 Watch "Is The Universe A Hologram?" on RU-vid ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-iNgIl-qIklU.html
The observable Universe has a beginning, its just not the beginning of everything. Our Universe belongs as a much larger structure, an infinite structure made out of an infinite number of other universes all belonging to what we will call the Omniverse whose nature is governed by the Aethoesystem. Each individual universe starts off as a magnetic singularity. This infinitely small singularity is then transfixed to the end of an umbilical cord tethered to the Aether by the Aethoesystem which then begins to pump the Aether into the singularity which then makes the singularity of magnetic force highly energized. After a time, depending on the singularity’s position in the Omniverse, both spatially and mathematically, the Aethoesystem would begin to transform the Aether into the fundamental particles that will be needed for the successful maturation of the Ovum along with the nuclear forces to assist in the particles processing. Once the particles begin to fill the singularity it simultaneously begins to expand. As the Aether transforms, fundamental particles begin to appear and fill the ovum which begins to grow in size as more and more particles enter, jockeying for room that just isn’t there and creating chaos as the particles continue to bang into each other, and if one is anti-matter and the other normal matter, they then destroy each other’s vibration, releasing the energy back to the Aether and creating quite a bang as a result. During this initial period, the magnetic field splits into two separate forces, the postromagnetic force and the electromagnetic force. The postromagnetic force then attracts the heavier anti-particles into the center of the ovum and the electromagnetic force attracts the lighter normal matter outward, around the center. This then continues until the ovum reaches a certain size, again depending on its designation in the omniverse, at which point the fields would reach their elasticity point and snap, releasing from the umbilical cord and causing the ovum to spin off into the Aethoesystem as the magnetic forces reverberate back and forth throughout the ovum, and once again creating absolute chaos. As this occurs, Gravity then takes holds and keeps it all together while each of the magnetic fields, already permeating throughout the ovum, are able to establish order and create a stable structure for the ovum to maturate and grow as it expands into the Aethoesystem to join all the other Universes in the Omniverse.
Einstein was a weasel who was seriously lacking in common sense. Important. Mr. Boris Stoyanov is a super bright and an HONEST physicist. He has agreed that the following post is "crystal clear": ELECTROMAGNETISM/energy is gravity. This is proven by F=ma AND E=mc2. Accordingly, gravity/acceleration involves balanced inertia/inertial resistance; as ELECTROMAGNETISM/energy is gravity. "Mass"/energy involves balanced inertia/inertial resistance consistent with/as what is balanced ELECTROMAGNETIC/GRAVITATIONAL force/energy, as electromagnetism/energy is gravity. Gravity IS electromagnetism/energy. That objects fall at the same rate (neglecting air resistance, of course) PROVES that ELECTROMAGNETISM/energy is gravity. Think about it. By Frank DiMeglio
It's pleasant to have a philosophical review, thanks. Accepting that the reason to say that spacetime is doomed might be because the "spatial" terminology such as "vacua" applies only topologically, ie it applies to the stable effective result of cause-effect, ..the Quantum Fields Mechanism of temporal superposition, (the apparently material substance of time-duration), that can be calculated as projecting & modulating time-inflation states, is a "nameless" principle of mathematical multiplicity. (Implying the conjectured structure of quantized reality postulated by the calculation of discrete identies in infinity) It's the "virtual reality" of potential +&- relative temporal position at 1-0D. In timespace, "vacua" applies to conduction, the "empty space" of frictionless, crystaline field harmonics, ..time only transition or "jump space". If the Planck dimension is an evolved state within the anthropic conditions of a complete Universe, then the observable universe is the Quantum "containment field" of evolving and re-evolving life cycles from seed to adult in sub contextual environments of corporeal bodies, by the quantum logic of this cause-event here-now. Spacetime => standard modeling, (suggested by the particular effects on a metastable field in a Wilson's Cloud Chamber), is the natural identification "nomenclature " of the Quantum Fields Mechanism, ie the apparent modulated-modules of quantized bubbles in a theoretical Quantum Chemistry equivalent to the BBT, in terms of phase-state. The LHC is operating on the same principle with more refinements. Timespace is Quantum, scalar properties of the unitary-function of connection. "Infinitely big" identifies the physical evidence of the extent duration-due to the effective connection of eternity in the reciprocal position to now, ie it's the orthogonal quantized scalar properties of the objective singularity with transverse-tangential displacement of relative possible probability, in temporal superposition terms, a mathematical nomenclature.
This guy is knowledge in fun (unless it's the contrary: fun in knowledge?) Anyway, one keeps bumping against him when one is a bit interested in the adventure
I'm reading rn Sean Carroll's "Something Deeply Hidden" book and so, managed to get Nima's very articulate presentation. It's obvious this guy is not only eloquent, he seems to have a firm grip of the subject. Obviously, many questions are unknown due to the cosmological horizon impeding observing vestiges of a multi-verse but, that point was well explained. I also liked the infinite apparatus vs finite limit to what is observable at the miniscule scale before a black-hole is created part, plus the notion space-time is doomed (or emergent) used to title a lot of these talks. This lecture/synopsis seemed more accessible than others I've seen. It would be nice if Nima could popularise more of his own work such as on the 1) Large Extra Dimensions and 2) the Amplituhedron scattering amplitudes work as these seem to be scientific theories of the large and small respectively, or put these talks' suggestions and tips for future theorists into popular written form as I reckon he's a talented speaker, no doubt, just would be nice for more popularising work, although, Sean Carroll does a good job at least so, that these talks are more comprehendable as a result! Cheers. 👍

"Existence" equals the fundamental, general state of time, and the phrase "a solid state of existence" is the reference frame against which the increasingly complex fluid states of change are related by the physical laws. To follow the sequences of structure and change around the "circle of infinity" from the least information component of a point, the potential minimum quanta, by increasing stages of complexity to the ultimate inverse quality of the "hole" in which the point potentially exists relative to the whole, is an infinite combination of infinity describing the connection. Temporal superposition is the self-shaping statement of existence and mechanism by which shaping is constructed, and is modeled by suspended particles in an echo chamber. It should exibit a blackbody spectrum but the cloud is collected by resonance. (always wanted to watch a Wilson's Cloud Chamber in action, and have now done so) Astronomy is in the actual cloud chamber to watch, and "it's fun to imagine", with the "echo" idea, why there's only one electron zapping in and out of the infinite possible positions available while remaining forever entangled, and so on. The more resilient shapes of resonance will be due to the relative persistence of prime numbers, and that is why the Polar/Cartesian coordinate connection is the dominant shape of resonance inside the sphere of higher dimensions, and why superconductivity applies near the extremes of shape and motion, or it's also interpreted as infinitely fluid-distributed eternity at the infinitly limited position, now. The possible arrangements of primes in complex conglomerations of connection that can then be associated with the constants is, as the Professor has demonstrated, difficult to calculate. ----- Probability "chips will fall where they will", means that like, "Gold is where you find it", is WYSIWYG Actuality, in which ONE-INFINITY prime-connection coordination is discovered set in absolute superimposed Temporal "solidity of No-thing ", of Zero-infinity Black-body Kelvin flat-space ground-state envelope sites, in fractal Eternity-now Interval, Cosmological placement.
@@deandeann1541 you can make the argument that the reciprocal of quantization is the relative-timing ratio-rates Perspective of Singularity-point i-reflection containment positioning, or is making a state of information-unity equivalent to "Prime", so when applied to Relativity of how holographic Modulation Mechanism Singularity positioning condenses superimposed Quantum-wave states as "numerical" wave-particle nodal-vibrational Quantum Computational "measures" of time-timing, we perceive the Physics landscape to be composed of Primes and Cofactors in Polar-Cartesian coordination-positioning wave-packaging. OK?
@@davidwilkie9551 🤣🤪😝Yes, yes! And the inverse of infinity is the infinitesimal - which is indeed a deep and subtle concept, as deep and subtle as infinity itself, and related to infinity like two brothers are related - both are important and the base upon which much advanced mathematics is built, thus I have pondered the concepts in my youth. As I read your material above I can't help but to likewise ponder what is the inverse of intelligence and understanding - it must be that such an inverse is also important and worthy of my attention - yet I must admit that the above mentioned inverse is beyond my limited abilities to comprehend, perhaps you will have to find a more suitably endowed student, with abilities more aligned with your own.

i think we can safely leave gods out of fine tuning, if a mind created the universe it had the laws of physics already in place and had to follow those laws, a god-creator could set all the numbers to "1" and we would accept that as natural. the thought that a guy with a beard was going "right, that's gravity sorted, oh frig, expansion, now what numbers will work" is a bit silly.
درود به نیمای عزیز من به فیزیک و فضا خیلی علاقه دارم ولی زبان انگلیسیم خیلی ضعیف است کاش فارسی بلد بودی برای ماهم صحبت میکردید. یاحداقل زیرنویس فارسی میگذاشتید.سلامتی ترا آرزو دارم.
Thank you Nima for this extremely spellbinding account of 'multiverse and fine tuning' and for finding room for the anthropic principle (however cautiously). However, I would like to think how phase transition affects non-life matter to turn into life and consciousness (due to self-organizing and self-simulating property of matter), that I am tempted to assume similar self-simulation of a universal intelligent consciousness observer collapsing the QF into particles, just as in the double slit experiment of QM, fine tuning the parameter space to create life and human consciousness, with perfection and with probability one. Then man and god could be entangled. And divine purpose will be meaningful. The infinite (or zillions) of solutions to the string theory are like the zillions of different snow flakes, no two are similar, may not imply multiverse with different laws and values for CC and may imply laws of physics are the same everywhere (my limited knowledge says).
This is an invitation to see a theory on the nature of time! In this theory we have an emergent uncertain future continuously coming into existence relative to the spontaneous absorption and emission of photon energy. Within such a process the wave particle duality of light and matter in the form of electrons is forming a blank canvas that we can interact with forming the possible into the actual! The future is unfolding with each photon electron coupling or dipole moment relative to the atoms of the periodic table and the wavelength of the electromagnetic spectrum. As part of a universal process of energy exchange that forms the ever changing world of our everyday life the ‘past’ has gone forever. At the smallest scale of this process the ‘past’ is represented by anti-matter annihilation with the symmetry between matter and anti-matter representing the symmetry between the future and the past as the future unfolds photon by photon. In such a theory the mathematics of quantum mechanics represents the physics of ‘time’ with the classical physics of Newton representing processes over a period of time, as in Newton’s differential equations. In my videos I explain how this process is relative to temperature and the phase changes of matter.
Is theoretical physics now becoming like modern art. In the case physics most people can visualize space-time as determinist, wheras the majority of people cannot visualize non deterministic outcomes.
Can you throw dice? That's a non-deterministic experiment. That you imagine that there is some sort of god-like creature that could predict the outcome of a throw is a figment of your imagination and nothing more.
It's a tick. He's concentrating intensely. Have you ever watched a musician play live? They make some weird faces and gestures too. It's kind of the same thing. He could probably not do it, but it would make him self-conscious and not as focused on his thoughts and articulations.
Considering the fine-tuned universe as a compelling argument or that there is "something more" to our reality doesn't or wouldn't necessitate being or becoming religious lol.. Nima has a MASSIVE bias toward quantum mechanics (even though he doesn't specialize in the field) and thinks that most experiments conducted in quantum physics are somehow all flawed (double-slit experiment, quantum entanglement, retrocausality, etc) and are uninteresting.
@@SpiritTracker7 So you are basically telling me that you don't understand what makes low energy quantum experiments boring and useless. OK. You are not the first one. There is a whole generation of tabletop physicists out there who haven't been able to get over those things, either. Nima is simply not one of them.
@@schmetterling4477 Also, when the gentleman asks about quantum physics and it's connection to consciousness, Nima basically cuts him off and hand waves the whole field as uninteresting. And it's not just "tabletop physicists" that find such dismissal as utterly intellectually irresponsible but there have been actual authoritative working-in-the-field physicists who have written books on the subject matter. Of course Nima doesn't need silly experiments when he has scribbled-on napkins as compelling evidence.
By the way, "multiverse" conjecture doesn't deserve to be in the same sentence as Space-time and quantum mechanics. Space-time is a concept that has been accepted for over a hundred years and quantum mechanics is applied science now. Multiverse conjecture was invented to counter the anthropic principle/fine-tuned universe theory out of desperation. These guys have been literally "fine-tuning" counterarguments to the "apparent" fine-tuned universe "problem" for a century.
You stop being a scientist as soon as you use the words "it has been generally accepted for x amount of time". At that point you turn into your crazy conservative uncle who doesn't have a future and should not be invited to family dinners.
@@schmetterling4477 Not at all, it's how science works. When something is generally accepted among the scientific community it means nothing has come along with enough compelling evidence to provide an alternative explanation. I have nothing against theoretical science... but the multiverse conjecture is pure theoretical mathematics based on the imagination of highly educated thinkers. I've listened to Nima before.. he is very intelligent but that doesn't mean he is right. Take a look at the "big bounce" proposal for example. It's a highly sophisticated model that no-one actually understands outside of the 3 or 4 people who worked on it. If science is supposed to be testable, then none of these models have ever been tested. They are nothing more than thought experiments with overly sophisticated mathematics bent in such a way to support them. Now in order for it to be science, we just have to observe another universe or compelling evidence that more exist.
@@schmetterling4477 I am actually referring to a Nima lecture on another video called "Public Lecture | The End of Spacetime - SLAC National Accelerator Laboratory".. I just happened to land on the above video and commented.
@@schmetterling4477 "science works by observation"... oh my... now we enter into empirical/experimental physics vs theoretical probabilities/physics. By definition, you just ruled out the multiverse conjecture as real science. We are on the same page after all.
