  • I get constantly asked if I could please comment on other people’s theories of everything. That could be Garrett Lisi’s E8 theory or Eric Weinstein’s geometric unity or Stephen Wolfram’s idea that the universe is but a big graph, and so on. First I explain what physicists mean by a theory of everything and by grand unification (or a grand unified theory, respectively). Then I explain why the current approaches are no very promising but why, forgive me, I nevertheless think it's good to have them.

    This why I love your channel , you don't just accept things and you are very critical of the state of today's physics . That's the mentality needed , if we are to keep going forward in the advancement of physics . And yes the universe doesnt give a damn ,what we want or what we think as pretty . It is what is it .

      I like the video so much, but I have a theory of everything too.
      According to Buddhism Suddhāṭṭhaka (“suddha” for “pure” or fundamental” + “āṭṭha” or “eight”) means a unit of matter consisting of eight fundamental entities. Four of these are the “satara mahā bhūta“ (The Four Great Bhūta. Bhūta is another name for “ghost” because of their elusive nature.): Pathavi (Solid/Earth), āpo (Liquid/Water), tejo (Heat/Fire), vāyo (Gas/Air). These are indeed the most fundamental units of matter, but they cannot be detected by themselves. The four mahā bhūta ('Matter') are with four basic “gati” ('Character of Matter'/ 'Antimatter'): Pathavi gati (hard/coarse), āpo gati (bound/attracted/liquidity), tejo gati (fiery or energetic), vāyo gati (motion). Thus, in Buddha Dhamma, it says, “gati (character) attracts a similar gati”. (*Read more about "The Origin of Matter - Suddhāṭṭhaka" at Pure Dhamma website.)
      According to my mathematical calculations the Universe can make two objects (Matter and Antimatter) using the 6 gaps of the 6 directions:
      (+0-0)3 x (+0-0)3 = Matter x Antimatter
      According to this mathematical formula (a+b)2=a2+2ab+b2 we can write (+0-0)2 as 02 - (+1-(-1)) x 0 x 0 + 02
      (+0-0) x (+0-0) x (+0-0) x (+0-0) x (+0-0) x (+0-0) = (+1-(-1))3 x (+0.0-0.0)3
      (+1-(-1))3 can make 8 dimensional forms of space with a nature of Matter and Antimatter which can cause to convert those 8 dimensional forms of space into 16 quantum dimensional forms of space like Quarks, forces and etc.
      (+0.0-0.0)3 can make extra dimensions, Higgs boson and etc.
      Possible or Probable Outputs of (+0.0-0.0)3
      (+0.0-0.0)3 = (+0.0-0.0)x(+0.0-0.0)x(+0.0-0.0)
      The Most Possible Output:
      (+0.0-0.0)3
      = (0.02 - (+1-(-1)) x 0.0 x 0.0 + 0.02)x(+0.0-0.0)
      = ((+1-(-1)) x 0.000 - (+1-(-1)) x 0.000)x(+0.0-0.0)
      = ((+1-(-1)) x (0.000 - 0.000))x(+0.0-0.0)
      (+0.0-0.0)3 = ((+1-(-1)) x (0.000 - 0.000)) x (+0.0-0.0)
      I write it like this for identification:
      (+0.0-0.0)3 = (+(1)-(-(1))) x (0.000 - 0.000) x (+0.0-0.0)
      Now we can combine the results of (+0.0-0.0)3 with the results of (+1-(-1))3 to see the most possible total result:
      (+1-(-1))3 x (+0.0-0.0)3 =
      (+ (+1)3 - ((+1)3 x (-1) - ((-1)2 x (+1)2)) + (-1)2 x (+1)
      - (+ (+1)2 x (-1) - ((+1)2 x (-1)2 - ((-1)3 x (+1))) + (-1)3))
      x (+(1)-(-(1))) x (0.000 - 0.000) x (+0.0-0.0)
      (+1-(-1))3 x (+0.0-0.0)3 =
      (+ (+(1))(+1)3 - ((+(1))(+1)3 x (-1) - ((+(1))(-1)2 x (+1)2)) + (+(1))(-1)2 x (+1)
      - (+ (+(1))(+1)2 x (-1) - (+(1))((+1)2 x (-1)2 - (+(1))((-1)3 x (+1))) + (+(1))(-1)3)
      - (+ (-(1))(+1)3 - ((-(1))(+1)3 x (-1) - ((-(1))(-1)2 x (+1)2)) + (-(1))(-1)2 x (+1)
      - (+ (-(1))(+1)2 x (-1) - (-(1))((+1)2 x (-1)2 - (-(1))((-1)3 x (+1))) + (-(1))(-1)3)))
      x (0.000 - 0.000) x (+0.0-0.0)
      It gives 16 results and this unbalanced result (Higgs boson): (0.000 - 0.000) x (+0.0-0.0)
      Now I can show all the most possible results (the 16 dimensional forms in atoms called quarks, forces and etc) like this:
      Distance of Directions in beginning of the Universe: (+0-0)6
      =

      16: + (-(1))(-1)3))
      ))) x
      This should be the Higgs boson in Standard Model (in particle physics):
      17: (0.000 - 0.000) x (+0.0-0.0)
      Each electron has an electrical charge of -1. Quarks make up protons and neutrons, which, in turn, make up an atom's nucleus. Each proton and each neutron contains three quarks.
      The Higgs boson field came from this: (+0.0-0.0)3
      And this (+0.0-0.0)3 is combined to this: (+1-(-1))3
      So always there is an interaction between the final resultS of this: (+1-(-1))3 x (+0.0-0.0)3 with this (0.000 - 0.000) x (+0.0-0.0) which can make a mathematical connection between those things. (Eg: Tau : Muon : Electron = 2000 : 100 : 0.5 = 4000 : 200 : 1)
      The reason to the birth of Atoms is the reason to The Origin of Matter and Antimatter. And it is the first part of 'The Theory Of Everything'.

No, I'm not, I'm just looking to find out more about the world, and if it turns out there is a simple ultimate law which explains everything, so be it, that would be very nice to discover. If it turns out it's like an onion with millions of layers and we're just sick and tired of looking at the layers, then *that's* the way it is! But whatever way it comes out, its Nature is there and She's going to come out the way She is.

      My initial understanding of science still holds today. Science is propelled forward by investigating where observations don't equal predictions. Each revolution in our ability to observes tends to lead to breakthroughs in our understanding, since the inconsistencies between observations and predictions get highlighted. This is precisely what led to General Relativity.. There were many observations that didn't square with Newtonian physics (where gravity is concerned) (read about the orbital anomalies of mercury to get an idea of how this came about).
      Making decisions on where to look based on mathematical beauty is an inane way to do science, yet it is where many in theoretical quantum physics live right now.

      The following proves Spinor Theory is correct.
      Quantum Entangled Twisted Tubules: "A theory that you can't explain to a bartender is probably no damn good." Ernest Rutherford
      When we draw a sine wave on a blackboard, we are representing spatial curvature. Does a photon transfer spatial curvature from one location to another? Wrap a piece of wire around a pencil and it can produce a 3D coil of wire, much like a spring. When viewed from the side it can look like a two-dimensional sine wave. You could coil the wire with either a right-hand twist, or with a left-hand twist. Could Planck's Constant be proportional to the twist cycles. A photon with a higher frequency has more energy. (More spatial curvature). What if gluons are actually made up of these twisted tubes which become entangled with other tubes to produce quarks. (In the same way twisted electrical extension cords can become entangled.) Therefore, the gluons are actually a part of the quarks. Mesons are made up of two entangled tubes (Quarks/Gluons), while protons and neutrons would be made up of three entangled tubes. (Quarks/Gluons) The "Color Force" would be related to the XYZ coordinates (orientation) of entanglement. "Asymptotic Freedom", and "flux tubes" make sense based on this concept. Neutrinos would be made up of a twisted torus (like a twisted donut) within this model. Gravity is a result of a very small curvature imbalance within atoms. (This is why the force of gravity is so small.) Instead of attempting to explain matter as "particles", this concept attempts to explain matter more in the manner of our current understanding of the space-time curvature of gravity. If an electron has qualities of both a particle and a wave, it cannot be either one. It must be something else. Therefore, a "particle" is actually a structure which stores spatial curvature. Can an electron-positron pair (which are made up of opposite directions of twist) annihilate each other by unwinding into each other producing Gamma Ray photons.
      Does an electron travel through space like a threaded nut traveling down a threaded rod, with each twist cycle proportional to Planck’s Constant? Does it wind up on one end, while unwinding on the other end? Is this related to the Higgs field? Does this help explain the strange ½ spin of many subatomic particles? Does the 720 degree rotation of a 1/2 spin particle require at least one extra dimension?
      Alpha decay occurs when the two protons and two neutrons (which are bound together by entangled tubes), become un-entangled from the rest of the nucleons
      . Beta decay occurs when the tube of a down quark/gluon in a neutron becomes overtwisted and breaks producing a twisted torus (neutrino) and an up quark, and the ejected electron. The phenomenon of Supercoiling involving twist and writhe cycles may reveal how overtwisted quarks can produce these new particles. The conversion of twists into writhes, and vice-versa, is an interesting process.
      Gamma photons are produced when a tube unwinds producing electromagnetic waves.

I guess I don't fully understand the role she is playing, but continuing her theme about productive use of time, I enjoyed the time spent on this one which I guess is a little compensation for the time 'wasted' on others. I don't mean to sound harsh or unkind, it's critique rather than criticism.

    Oh lord I love your perspective!
    I just stumbled upon your channel and as someone who's just finished a phys undergrad and has decided to continue learning about physics on my own rather than through academia, since it's more of a personal curiosity thing than an academic pursuit, I love how questioning of the way physics is going you are.
    I am firmly held by the idea that we are roughly where classical physics was just before the discovery of quantum mechanics, and that there's either an underlying classical world waiting to be discovered (like in 't hooft's cellular automaton interpretation of QM) or that there is entirely new physics to be discovered that we have not beforehand considered.
    I've even started questioning the fact that we do use calculus for EVERYTHING, it just reminds me too much of the old adage that "everything looks like a nail to a man with a hammer"... Maybe there's another way to do maths and physics that doesn't start with calculus. Or maybe multiplicative type calculus would show us some new insights we haven't seen before. I don't know, and my favourite thing is that right now- probably none of us know

    I agree that "pretty" math can lead down many rabbit holes and is often based on hunches, but I think that it is possible to create a single theory that accurately predicts all aspects of reality we can observe. I don't think we are anywhere close to it, but there is no reason to think it can not be done. It is a very logical deduction.

    Just a few days ago I was exposed to your lectures Sabine, and my conclusion, from the present lecture, is that indeed the universe can be governed by two non-integrating theories (quantum theory and general relativity). This is my first time having the "dare" to think so. It's thanks to you Sabine. On the other hand science is based on endless curiosity without stopping and staying in an existing state “warm and comfortable”. Thus even if there is a built-in separation between the two theories, we must not stop asking questions. Even if there is no total solution that unites the two theories, still the research itself can bring very great benefit to science and hence to humanity

    • @reverseview2522
      @reverseview2522 Před rokem

      I don't think your conclusion is correct. Sabine said that it is imperative to develop a theory of quantum gravity so that the two theories are combined in a consistent way. What she said is that it is not necessary (and she does not see it happening any time soon or even ever) that the theories can be combined in a way that demonstrates a link between all the forces so that we can talk about a single force rather than many different forces. In other words, what is disputed in this video is that there is a simple and elegant theory that describes every observed phenomenon, but NOT that there is a consistent theory that describes all phenomena.

    I once, during my working life, was an IT security manager. I looked at different kinds of risks, like data theft, process manipulation, fire in a data center. I became aware of the difference between threats and vulnerabilities, and the relationships between them. I acknowledged that successful measures had to be about organization, people and technology. And I acknowledged the value of a mix of preventive, detective, repressive and corrective measures. Finally, it was absolutely clear to me that taking measures in itself wasn’t enough, one had to test and check on a regular basis, learning from the results, adapting the security system where necessary. This all, in a clear organizational framework of the security process itself, assuring the quality of that process.
    Nowhere was there a need to unify the security effort, on the contrary, there was strength in diversity of aspects: what the one aspect wouldn’t do satisfactorily, the other aspect would pick up. The whole diverse framework would ensure success by flexibility. The simple problem setting was: what can go wrong, and what is effective against it? Experts from different directions provided the input necessary to be good at what we were supposed to do.
    So, why would physicists look for a unification theory? Sure, it would be pretty if possible, but in light of the above, this striving is just answering the wrong question. Which problems are there to be solved, with which toolset can this be done best? To me, progress would mean, a better understanding of the problems at hand, and a better toolset to tackle these problems. Whether they would be diverse or unified would be quite irrelevant. Those paying these physicists could have some influence on them, by asking to set proper goals to achieve, instead of performing in a beauty contest. Or is this standpoint just a bit too matter-of-fact, not fitting the freedom of science? My guess is, it should be possible to combine the two, conflicts about it leading to a well understood set of checks and balances, working towards a result.

A Dutch saying goes, lost a bit in translation: there is a difference between being right, and “getting” right (people acknowledging you are right).
      My solutions may not work for you, but I start mentioning them anyway. Of course I not always got my way. So I made sure the case at hand was crystal clear: problem, alternative solutions, best solution, cost benefit analysis. Complete, but as short as possible. This way, I often got my way. When not, phasing was an attractive option, trying out the easiest and most promising part first, for a fraction of the cost. The additional benefit was learning while doing so, sometimes phase 2 wasn’t even necessary. And sometimes I got a firm NO, then I looked at the risks again, looking for alternatives that, while not ideal, could at least take the pain away.
      I guess, the above is not applicable to you, except the first part. You must write down your solution as good as you can, it must be crystal clear, not only for you, but also for your peers. Then comes the difficult part, to be compared with marketing. The aspect I would pick out is communication channels. Contact your peers, editors, all kinds of stakeholders, defend your case. Ask feedback, and maybe you have to modify if those peers have a point. Ask them to help you to publicize you solution. It may take some time: perseverance, patience are very important. You failed? Try again, try to find alternative channels: television, CZcams.
      Maybe you already did all this, and a bit more, maybe you are still in the middle of it: go on! And in the end, you will succeed, or alas, not. If the latter: if you tried everything, there is no shame on you.

Both Eric (a mathematician) and his brother Bret (an evolutionary biologist... pretty much the opposite of eugenics) are PROGRESSIVES. The basic beliefs being universal human rights, meritocracy, scientific ethics, freedom of speech, pro limited social safety net, anti war, pro environment, anti authoritarian etc. (aka from a conservative perspective the basic mark1 hippy: tree hugging, peace loving, tolerance spouting, pot toking, granola munching, crazy haired radicals...). The basic stuff codified by the enlightenment (...and...well that other long haired Jewish hippy: jesus), and until recently, propagated through the liberal arts in the university system that they believe has been infiltrated by resentful illiberal authoritarian leftists...the kind orwell warns about in animal farm. Guys who don't like people being able to advance the sort of ideas that let you safely question the powerful and the psychopaths and narcissists who crave power and use manipulation and political correctness to take it. The barbarians that have broken through the gates and are currently metastasizing through our corporate and civic institutions. See Evergreen or chaz/chop for a master class on the destructive power of this game theoretically unstable ideology. It's Nash equilibrium is somewhere between dumpster fire and nuclear waste in terms of its ability to contaminate and depopulate/destroy social habitats.
      The systen of enlightenmnet values that both of these brothers have dedicated their lives to defending represents an existential threat to fascism, communism, marxism, maoism, neoliberalism and other autocratic totalitarian and plutocratic economic or government systems. Eugenics is the literal antithesis of their belief system. Eugenics is an unstable unethical borderline psychopathic system of thought that countenances and was used to justify some of the most horrible atrocities committed by the Nazis! Many of the Weinstein's relatives parished as a result of this ideology. I can assure you that they are not supporters of eugenics. Opposition to the type of fascism that nurtures thus ideology is probably one of the few things that could actually motivate them and those of like mind to physical violence or armed conflict.
      Harvey Weinstein (no relation to Bret and Eric) was a friend and at times, co conspirator of Jeffrey Epstein who was among other things a psychopath, pedophile, serial rapist, AND eugenicist. You've got a pretty huge case of mistaken identity going on here.

    You are correct 'time' is extremely valuable and not to be wasted. So how to know if someone is worth spending time with and listening to? IMO it first centre's around the act of determining as best you can - does that person demonstrate that they have a functioning moral core that as a prerequisite is largely independent of their ego? That can usually be determined by investing a few hours of listening closely for indicators. One such indicator is showing empathy and understanding for those you disagree with at a fundamental level. Also, not willing to be seduced by beauty when you are enamoured of beauty (musical beauty) indicates someone who is well centred, grounded and clear headed. And so I give you what I feel is my most valuable possession. Thank you for taking the time to educate us.

    The thing that has shocked me most watching top physicists interviewed on CZcams etc. is the very poor grasp these people have of the relationship between Maths and Physics. When I was a student I found this very confusing, in fact it was the main problem which blocked my progress in learning Physics. Years later after I graduated in Biochemistry I turned to a study of the foundations of Mathematics as a hobby being still very much bugged by this confusion. I discovered that during the late 19th and 20th century mathematicians had established a very clear understanding of what mathematics is and how it works. The nature of maths and its relationship to Physics and other natural sciences was in fact quite clear. However today I find people with Nobel prizes espousing Platonist ideas about maths and equating Maths and Physics as part of the same thing. They even confuse mathematical 'truth' (a purely logically defined status, RATIONALISM) with scientific truth, something which is never fully achieved only approximated to and based on the empirical tests of theories (EMPIRICISM). I find it difficult to understand how people who have such proficiency in the application of Maths have such a poor idea of the difference between the purely logical, rational and linguistic on the one hand and the world of real natural phenomena on the other. The way I put it is they confuse a drawing of a house with a house and believe the two equivalent.

    Recently I have read in Paul Davies's book, "The Mind of God":
    "It is widely believed among scientists that beauty is a reliable guide to truth, and many advances in theoretical physics have been made by the theorist demanding mathematical elegance of a new theory. Sometimes, where laboratory tests are difficult, these aesthetic criteria are considered even more important than experiment. Einstein, when discussing an experimental test of his theory of general relativity, was once asked what would he do if the experiment didn't agree with the theory. He was unperturbed at the prospect. "So much worse for the experiment", he retorted."The theory is right!". Paul Dirac, the theoretical physicist whose aesthetic deliberations led him to construct a mathematically more elegant equation for the electron, which then lead to successful prediction of existence of antimatter, echoed these sentiments when he judged that "it is more important to have beauty in one's equation than to have them fit experiment". (p.174-175)
    So why, then, genius scientists of the past thought mathematical beauty as a guide?

      2. That we won't find a way to do it, in *spite* of not having a ToE (we might find the necessary physics to do what you want, *before* figuring out how it all fits together, and it just becomes one more piece of the already messy puzzle).

    Positive and negative charged particles elude me. I would like to learn more about charges, or about mass, especially if some practical purpose can come of it. By learning science, I am searching more for hope than knowledge, hope in place of knowledge, which I feel is a more pragmatic endeavor. Thank you for your videos.

    Thank you for your excellent lesson and channel structure and fine edition. Well. Sorry if i ask you something about philosophy... If we don't actively seek for supersymetry (which is a quite plausible theory) and say - in general terms - if we don't seek for possible models with higher levels of explanatory generalization power together with larger descriptive scopes (like grand unification) then I ask you what type of experimental goal should we undertake out of pure applied physics (or non fundamental physics) in the research for the fundamentals of nature? Sorry for my poor english.

    _Do_ we know gravity even exists at a particle level? I mean, we haven't been able detect gravitational effects at that level, right? So isn't it possible that gravity doesn't apply at all on that scale?

      Whatever goes on with gravity on the level of elementary particles, we know that it adds up to the gravity we are used to deal with. You need a theory that explains how this happens, regardless of whether you want to still call it gravity.

      Possible and even plausible IF gravity is an emergent phenomenon rather than a fundamental force.

      @@SabineHossenfelder I'm a total layman, but I know gravity is not a force but a resultant curvature of space-time, so to quantize gravity (as it were) you would need to quantize the curvature. Maybe the Planck constant is related? However maybe the other 3 forces are not "forces" of QFT but rather curvatures in some Hilbert space. Maybe Einstein was trying to get there but failed. Or maybe mass can't curve s-t until a threshold value is reached, much like the quantized energy levels that Planck help to derive.

      That is probably why she put the three up and gravity down.
      Gravity is more of a space geometry thing. Matter/Energie does something to space and the other way around. Space is the "field" not some field in space. It is more of a meta effect like all the fictitious forces around it. The only hint we have is the Higgs mechanism.

    My hypothesis is that we are wrong about alot of QM, especially the interpretations.
    Personally I would throw out Entanglement and Superposition and rethink all this stuff. And perhaps not rely too much probability and statistics or extended them far beyond their limits.

    • @firstaidsack
      @firstaidsack Před 2 lety +1

      The interpretations part is okay, but entanglement, superpositions, and so on are primarily mathematical forms that have been repeatedly tested and verified beyond any reasonable doubt. They make precise quantitative predictions that have been confirmed in countless experiments. You're still free to disagree about what those mathematical things mean but you cannot just throw them out because you don't like them. Science is not philosophy.
      If you want scientists to stop relying on probability and statistics give them something else that can be empirically tested and verified and produces more and better results than probability and statistics already do.

    I like hearing people describing their concepts as much for enjoying and admiring their logic and creativity as for the thoughts they invoke in my mind. Their ideas give me a platform to test my own ideas against. This is all part of a search for knowledge that spans our entire lives, and is the most fulfilling part of my existence, other than family and personal relationships, which will continue till I die. All science in all fields that is sincerely undertaken and not fraudulent should be funded, this is the core of our civilisation, but the exploration of how energy creates everything is the greatest detective story ever undertaken.
