    • If you want to know how it all works, master special relativity. And I don't mean the tons of math that describes observations of it. SR addresses time, space, mass, and energy. Can't you see how that touches every aspect of our universe? And how it works is EXTREMELY simple. When SR is described, 20 or more earth shaking Nobel prizes will follow in months. Physics will flash ahead with lighting speed.

    • Physics at our scale are incorrect, so that leads to quantum physics being even more incorrect. Mass is not attracted to mass for a start, mass is repelled by mass. There's no such thing as a pull force, and there is actually only one force. So basically all of physics are delusional to begin with. Peer review means to join the delusional gang. Mass moves towards holes in mass, because it flows with gravity like water moves into a sponge, and can take something with it. The bigger sponge has the most mass, but also the most holes. Observation of the Cavendish experiment does not count as observation at all, it's invisible. Peer review is the Emperor's New Clothes, you see the invisible in the Cavendish experiment, you see mass attracting mass, but the truth is that you see nothing at all. With such bad teachers to follow you will never get anywhere. I ignore everyone... I ignore the crazy gang.

The accepted pattern will not appear. There will be marks where the humps were. Present science cannot explain this. Get the longest wave length you can. Shorter wavelengths will produce errors. I know why.

But the organization of philosophers (IAI) has decided he is a waste of time. Even though some of the big brains will not put something in the real world to demonstrate an idea: this person has suggested a real world experiment that might demonstrate something very important. You criticize the system but let your assumptions keep you on a similar path. Was it BCS that told me SR is a dead horse? Com-on man.

    • I think everyone is thinking about it wrong. I mean take for a example superposition it's not all things at once or so simple. It's how the integrated differences give rise to a difference or become a difference while maintaining itself so both states at the same time but through different methods. Imagine a guy doing the wave, the energy just traveled trough the differences and didn't stay as one thing but moved trough it's integrated differences. What I mean is that the "quantum wave collapse" is the syncing/integration of the differences. Think water and it's differences taking the shape or variable differences but maintaining itself as water or how words embody the difference of other things. Meanings are the same as superposition adnas we integrated more, the uses and differences grow that it can integrate with, like math repping reality and then using an equation to find a prediction and then using us ass connected difference, we can integrate

    • If we could measure the gravity of a single electron what would that give us? If we send photons one at a time thru 2 slits, each photon hits a screen at only one point, however the points are spread out in an interference pattern as if each photon went through both slits, as the wave function stated. But if we put a detector after one slit then we will see that half the photons hit our detector and half the photons go straight through the other slit directly to the screen. We could do the same thing with electrons. We cannot detect an electron's gravity, but we can measure its charge. What experiment are we wanting to do with gravity that we can't do now with charge? Aren't we in the situation as with the photon? If we measure the charge then it stops being quantum. We would be in the same situation with gravity unless gravity is not quantum even though the particle is.

    • @@Nebukanezzer Actually, the idea comes from quantum mechanics and general relativity's principles. In quantum mechanics, particles like electrons can indeed be in a state of superposition, existing in multiple states or places simultaneously until observed. When we apply this concept to gravity, a force that depends on mass, it's logical to infer that an electron's gravitational influence might also exist in a superposition of all possible states. However, our current technology can't directly observe such quantum gravitational effects. This isn't about belief systems but about theoretical physics and the challenges of unifying quantum mechanics with general relativity. It's a fascinating area of ongoing research, not yet fully understood or observed.

Quantum mechanics shows particles like electrons in superposition, influencing their electromagnetic interactions. Yet, we wonder if gravity, inherently linked to mass, behaves similarly at quantum scales. This isn't about detecting an analog to charge in gravity but understanding if gravitational fields can exhibit quantum properties. If we could measure such effects, it could unveil new physics, bridging quantum mechanics and general relativity-a leap beyond what charge measurements offer.

  • One of the hardest things to wrap your head around, is the concept that a theory of everything does not describe the universe, but actually is the universe. Just like an astrophysicist has to realize the notion of up and down to be local, theoretical science has to realize the inherent imperfection of theory. 1 + 1 does not equal 2, simply because 1 does not perfectly equal one in any universe, realm or dimension, real or fictional, including mathematics. The source of a theory is the purpose it serves. Thus looking for a theory of everything is like the principal of commerce, a by definition bottomless pit. Not unlike in commerce, the objective should not be the optimisation of a virtuality, but the solution of a well defined practical problem. That step would solve a lot more than just a debate in physics.

  • Seems to me, and I think this is what Roger is getting at, that superposition can continue only so far, because at some point the different possibilities encompassed there within would start to have different impacts with regard to the interaction of the particles with gravity. And that it is those emerging differences that cause the collapse, so that gravity has something 'concrete' to work on, suggesting that gravity won't put up with quantum uncertainty that impacts it, because it is not equipped to do so. It implies that gravity is involved intimately with the quantum world, putting a constraint on it, keeping it within tolerable bounds. And if the world is 'computed', maybe there is a requirement for the collapse, encoded in the software, to ease the compute burden on gravity.

It comes down to information, and the leap to that no doubt was helped by the change in people's thinking brought about by the post-WW2 computer revolution. But there is a lot that goes unexplained, and our current theories eat away at the digestible bits around the edge of the big picture. It is not getting any easier to go further. It's been a long time since the last major paradigm shift such as string theory. We're overdue for another one. Perhaps Wolfram's work is a pointer thereto. He needs more brains to join in, but most of the theorists seem subsumed into string theory. In the longer term, perhaps after Wolfram's work starts to bear new fruits, we still have the problem of consciousness, about which we are currently clueless as to how to even start investigating how it ties in with Physics.

  • Toward the end there seems to be disconnect about “emergence”. I agree with Suchitra Sebastian that we cannot predict nontrivial “emergent” effects like superconductivity. But we should not confuse the limitations of our ability to predict with fundamental laws of nature (assuming they exist, as most physicists do). If one cares only about “Shut up and calculate”, then yes there’s a hard line between what we know about (e.g.) copper atoms and how they combine to produce superconductivity. We can compute it after the fact, knowing from experiments that it happens, but we did not predict it. This limitation of our ability to compute/predict must not be allowed to leak into our notions of the laws of nature. Nature has no such limits, and everything about superconductivity is implicit within the properties of individual copper (or other) atoms. This is a metaphysical distinction, but that is what this video is about.

There are several alternative modeling concepts. Why should we limit ourselves to one the was successful in the past. Why do you think it will continue to be successful? The second point is quite different. If there is one Meta lesson to be learned in physics it is the models exist to be destroyed. The ways to describe planet motions is an excellent example. 1. The earth is the center of the universe. 2.The planets have circular orbits. 3. The planets have elliptical orbits. 4. The planets have motions that cannot be described in any simple way. ergo The General Theory of Relativity. This should immediately bring up the question, what is the model in the future? What is number 5? What makes you think that the idea of concepts represented in mathematics is sufficient? There are other modeling paradigms. I don't see physicists using these alternative modeling methods for the existing data and problems that are unresolved today.

  • Amazing collection of scientific problems. I think about the emergence problem relationship with the quantum gravity problems. Perhaps IA can help us to find if there are some way to simulate or predict what possible propertires could emerge from situations with few constituents. I meanf: for Sir Roger Penrose the problem is in inconsistence of quantum mechanics, for Sabine Hossenfelder and other (I think) the problem it is in gravity understanding. But, if gravity is an emergence property of quantum systems how can we develop a theory that tell us how "one become another" as in supedrconductivity phenomena? Scientists have observed superconductity and developed a theory to explain it. Can we, with AI maybe, ind a pattern of thinking or a new mathematical construct that help us to understand thay "backwards way"? Or it is different for each phenomena? I guess that understand emergence better will help us to find both inconsistence in quantum theory and lead us to some quantum gravity theory. Thinking in emergence, perhaps it will not bring us to a unified theory, but just to an exaplanation of gravity as an emergence consequence of some aspects of quantum theory...maybe the opposite cab be truth kkk. I just want to thank you for the video with breathteaking problems to think.

  • Whatever the meaning assigned to the term _complete,_ the following requirement for a complete theory seems to be a necessary one: every element of the physical reality must have a counterpart in the physical theory. ~EPR What we see depends on light entering the eye. Furthermore we do not even perceive what enters the eye. The things transmitted are waves or - as Newton thought - minute particles, and the things seen are colors. Locke met this difficulty by a theory of primary and secondary qualities. Namely, there are some attributes of the matter which we do perceive. These are the primary qualities, and there are other things which we perceive, such as colors, which are not attributes of matter, but are perceived by us as if they were such attributes. These are the secondary qualities of matter. Why should we perceive secondary qualities? It seems an unfortunate arrangement that we should perceive a lot of things that are not there. Yet this is what the theory of secondary qualities in fact comes to. There is now reigning in philosophy and in science an apathetic acquiescence in the conclusion that no coherent account can be given of nature as it is disclosed to us in sense-awareness, without dragging in its relation to mind. ~Whitehead

  • The Ekeberg guy annoyed me. Mathematics is just the best language we have for describing physics. It grows and evolves as our understanding evolves. Equations in physics are like definitions in spoked language. Many great theoretical physicists weren't great mathematicians, so clearly math isn't the driving force. It's simply the language that is used to describe or define something in clear detail. The diving force is the question "so how do we describe/define this". The quest to find a mathematical descriptions of various particles, interactions, and phenomena is both what dives the math, and what drives the reevaluation of existing theory. The beauty of math as a language is that it enforces it's own consistency, and has an elegance when fully formed. Inconsistency or verbosity naturally point to areas where work is needed. The Standard Model Lagrangian is a perfect example of an elegant and consistent mathematical definition. The fact that we don't have an equation explaining waveform collapse points to an area our understanding is lacking.

  • When we know we are missing something fundamental, it is probably time to question some of our most basic assumptions. For instance, what if we are wrong about the invariant nature of light? We have defined the speed of light and taken it off the table for questioning. But consider for a moment the phenomena of water waves, which are well known to display the property of dispersion. Well, they also exhibit frequency downshifting over time (i.e., not invariant). What if light waves do something similar? What if they also exhibit some infinitesimal dispersion? What if the speed of propagation of the change of a field is constant at ‘c’ but electromagnetic waves travel at a very slightly less, but variable, speed? The honest consideration of such questions may just lead to the kinds of new models and understanding that the presenters are saying is needed.

Both work with the known 4 dimensions of space and time, and I'm sure mathematicians would have already exhausted this theory but maybe quantum physics could be of a 5th dimension that's why it's difficult to bridge, could be a silly question as I almost know zero about physics .Also maybe there might be a completely different language of mathematics for a 5th dimension not yet discovered, and quantum entanglement, I quote " two particles communicating with each other, faster than the speed of light, without information" maybe the information is beyond the mathematics that is available at the moment, maybe there's a lot of information being transferred, but not of the physical mathematics used.Beautiful and interesting video, I try to make sense with the little knowledge I have, day by day I learn more.💙💫🙏

    • This is actually a really old idea. Bernhard Reimann first proposed that space on a microscopic space may not have the same properties as the macroscopic, including possibly extra dimensions. Einstein followed in his footsteps formalizing time as a dimension. Very soon after Einstein published general relativity was an attempt made to unify gravity with electromagnetism, called Kaluza Klein theory, which added a compactified 5th dimension to spacetime. Kaluza sent his calculations to Einstein in 1919, so this is before Quantum theory had been formalized. String Theory works with the same idea but with several more extra dimensions, compactified in structures called calabi-yau manifolds. So theoretically formulating theories with extra dimensions isn't an issue, rather it's making testable predictions from those theories that's the problem.

    • The following ideas agree with you. If quarks have not been isolated and gluons have not been isolated, how do we know they are not parts of the same thing? The tentacles of an octopus and the body of an octopus are parts of the same creature. Is there an alternative interpretation of "Asymptotic Freedom"? What if Quarks are actually made up of twisted tubes which become physically entangled with two other twisted tubes to produce a proton? Instead of the Strong Force being mediated by the constant exchange of gluons, it would be mediated by the physical entanglement of these twisted tubes. When only two twisted tubules are entangled, a meson is produced which is unstable and rapidly unwinds (decays) into something else. A proton would be analogous to three twisted rubber bands becoming entangled and the "Quarks" would be the places where the tubes are tangled together. The behavior would be the same as rubber balls (representing the Quarks) connected with twisted rubber bands being separated from each other or placed closer together producing the exact same phenomenon as "Asymptotic Freedom" in protons and neutrons. The force would become greater as the balls are separated, but the force would become less if the balls were placed closer together. Therefore, the gluon is a synthetic particle (zero mass, zero charge) invented to explain the Strong Force. An artificial Christmas tree can hold the ornaments in place, but it is not a real tree. String Theory was not a waste of time, because Geometry is the key to Math and Physics. However, can we describe Standard Model interactions using only one extra spatial dimension? What did some of the old clockmakers use to store the energy to power the clock? Was it a string or was it a spring? What if we describe subatomic particles as spatial curvature, instead of trying to describe General Relativity as being mediated by particles? Fixing the Standard Model with more particles is like trying to mend a torn fishing net with small rubber balls, instead of a piece of twisted twine. “We are all agreed that your theory is crazy. The question which divides us is whether it is crazy enough to have a chance of being correct.” Neils Bohr (lecture on a theory of elementary particles given by Wolfgang Pauli in New York, c. 1957-8, in Scientific American vol. 199, no. 3, 1958) The following is meant to be a generalized framework for an extension of Kaluza-Klein Theory. Does it agree with some aspects of the “Twistor Theory” of Roger Penrose, and the work of Eric Weinstein on “Geometric Unity”, and the work of Dr. Lisa Randall on the possibility of one extra spatial dimension? During the early history of mankind, the twisting of fibers was used to produce thread, and this thread was used to produce fabrics. The twist of the thread is locked up within these fabrics. Is matter made up of twisted 3D-4D structures which store spatial curvature that we describe as “particles"? Are the twist cycles the "quanta" of Quantum Mechanics? 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. ( E=hf, More spatial curvature as the frequency increases = more Energy ). What if Quark/Gluons are actually made up of these twisted tubes which become entangled with other tubes to produce quarks where the tubes are entangled? (In the same way twisted electrical extension cords can become entangled.) Therefore, the gluons are a part of the quarks. Quarks cannot exist without gluons, and vice-versa. 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 Charge" would be related to the XYZ coordinates (orientation) of entanglement. "Asymptotic Freedom", and "flux tubes" are logically based on this concept. The Dirac “belt trick” also reveals the concept of twist in the ½ spin of subatomic particles. If each twist cycle is proportional to h, we have identified the source of Quantum Mechanics as a consequence twist cycle geometry. Modern physicists say the Strong Force is mediated by a constant exchange of Gluons. The diagrams produced by some modern physicists actually represent the Strong Force like a spring connecting the two quarks. Asymptotic Freedom acts like real springs. Their drawing is actually more correct than their theory and matches perfectly to what I am saying in this model. You cannot separate the Gluons from the Quarks because they are a part of the same thing. The Quarks are the places where the Gluons are entangled with each other. Neutrinos would be made up of a twisted torus (like a twisted donut) within this model. The twist in the torus can either be Right-Hand or Left-Hand. Some twisted donuts can be larger than others, which can produce three different types of neutrinos. If a twisted tube winds up on one end and unwinds on the other end as it moves through space, this would help explain the “spin” of normal particles, and perhaps also the “Higgs Field”. However, if the end of the twisted tube joins to the other end of the twisted tube forming a twisted torus (neutrino), would this help explain “Parity Symmetry” violation in Beta Decay? Could the conversion of twist cycles to writhe cycles through the process of supercoiling help explain “neutrino oscillations”? Spatial curvature (mass) would be conserved, but the structure could change. ===================== 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 production of the torus may help explain the “Symmetry Violation” in Beta Decay, because one end of the broken tube section is connected to the other end of the tube produced, like a snake eating its tail. 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, which is also found in DNA molecules. Could the production of multiple writhe cycles help explain the three generations of quarks and neutrinos? If the twist cycles increase, the writhe cycles would also have a tendency to increase. Gamma photons are produced when a tube unwinds producing electromagnetic waves. ( Mass=1/Length ) The “Electric Charge” of electrons or positrons would be the result of one twist cycle being displayed at the 3D-4D surface interface of the particle. The physical entanglement of twisted tubes in quarks within protons and neutrons and mesons displays an overall external surface charge of an integer number. Because the neutrinos do not have open tube ends, (They are a twisted torus.) they have no overall electric charge. Within this model a black hole could represent a quantum of gravity, because it is one cycle of spatial gravitational curvature. Therefore, instead of a graviton being a subatomic particle it could be considered to be a black hole. The overall gravitational attraction would be caused by a very tiny curvature imbalance within atoms. In this model Alpha equals the compactification ratio within the twistor cone, which is approximately 1/137. 1= Hypertubule diameter at 4D interface 137= Cone’s larger end diameter at 3D interface where the photons are absorbed or emitted. The 4D twisted Hypertubule gets longer or shorter as twisting or untwisting occurs. (720 degrees per twist cycle.) How many neutrinos are left over from the Big Bang? They have a small mass, but they could be very large in number. Could this help explain Dark Matter? Why did Paul Dirac use the twist in a belt to help explain particle spin? Is Dirac’s belt trick related to this model? Is the “Quantum” unit based on twist cycles? I started out imagining a subatomic Einstein-Rosen Bridge whose internal surface is twisted with either a Right-Hand twist, or a Left-Hand twist producing a twisted 3D/4D membrane. This topological Soliton model grew out of that simple idea. I was also trying to imagine a way to stuff the curvature of a 3 D sine wave into subatomic particles.

  • For physics to move forward consider these challenges Summary Here are the key components of all my physics posts. Photons are eternal and outside of time and distance. The singularity of photons began the Big Bang. Photons created mass through pair conversion of electron positron pairs in the Big Bang. These electrons and positrons made the elementary particles which in turn made the atoms. Neutrons and hydrogen atoms may be the same thing in different form. The proton neutron bond in the nucleus, kept neutrons from decay and was key to building all elements. Neutrons may be unstable protons. Protons, for the most part could only be created in the immediate era after the Big Bang. The key to atoms stability may be the deuterium nucleus or deuteron that help binds one proton to one neutron. The missing anti matter is in protons and neutrons. Photons, electrons, and positrons, are all different versions of the same thing. Virtual particles may be a key part of quantum leaps. The mass of the universe comes from photons converting to electron positron pairs in pair conversion. The energy of the universe comes from electrons and positrons annihilating and converting to photons. The universe is 5% charged matter and 95% neutral force. Dark matter is not gravity from invisible baryons pulling, but antigravity pushing from empty space. Dark matter and Dark Energy are both anti gravity pushing from empty space. The cosmological redshift supports this. The force from the Big Bang singularity was photons / dark energy / dark matter /anti gravity . They are the same. The force caused by acceleration is anti gravity, not gravity. Time has speed limits up to the speed of light. 95% of the universe seems to be without charge, detectable matter, or gravity: dark energy plus dark matter. The universe is open ended and will continue to expand.

  • Here’s a fun idea I have: Imagine you are a video character. How would you go about finding out what fundamentally makes up the game you live in? What experiments could you perform to verify how the universe was created? It is it even possible? We can figure out how the game works but not how it was created. We can infer how something is created within the universe the character lives in, there must be an initial mechanism for which the mechanics operate. The software and hardware. What experiments could one run existing within the video game to find the software and hardware the game runs on? Can a 2d being understand the mechanics of the 3d world it exists in? Can one determine the activities outside the cave by only seeing the shadow of the activities projected on the wall of the cave? There is a lack of information, we cannot determine what information is lacked.

    • I, of course, dont have answers, but to take your example... the way to search for something that would indicate the simulation would be like searching for floating point errors which accumulate in some situations, or the equivalent of a bit flip. I dont think its stupid to spend a minimal amount of time to look for these things in a physical sense, and its conceivable to me that some external informarion could be derived. Lets say that we have a simulation in a computer, and that the characters spend a lot of time monitoring all values they can find, or are allowed to observe. Stupidly, they would be able to observe something like the rate at which bits are flipped from cosmic rays. There would be no context, but it certainly would be external informarion about "something". In the end, I say it is best to stay curious on all physical phenomena, and to sometimes look where we wouldnt expect anything odd. Science is much more built on "Oh, that's really strange", than it is on "Eureka".

    • Some ideas for the "video characters" you describe: - Going to the limits of the ruleset they are existing in, e.g. getting closer to fundamental (atomar) functional elements, the spacial and temporal resolution, finding unintuitive behaviour and systems, apparent sources of "randomness". - Analyzing their own epistemologic scope and limitations, giving hints about the character and capabilities of the larger context they are embedded in. - Comparing their computer simulations with the actual world they live in. To the "real shadows" they see in their (allegory of the) cave, compare "simulated shadows" - "shadows of shadows" so to speak. - Examine the path of discovery itself, e.g. how it could or couldn't be predicted, in how far it is guided by teleological elements versus a posteriori knowledge i.e. experience. And for something different, if they have access to it, for recreational purposes, there's still metaphysics ;)

    • I'm not sure a video game is the best example for this. Real life phenomena, in stark contrast to video game objects, have the capacity to interact with everything. In video games, all interactions must be added by hand. In real life though, Magnetism, gravity, matter and EM waves all interact with other. Even if just very slightly in some cases, they do interact with each other. This means that they must share a very fundamental property that allows for this type of communication. There is a slight parallel to your video game example though. Whereas a video game character might only see the final product of the calculations, we as "higher beings" in this case know that everything processed and shown is actually purely electrical in nature. In that way, we "unified" (but also grossly oversimplified) all the computer-related phenomena. However, in the case of the video game character, I think it would be difficult for him to find out about this, since there are probably very few hints sprinkled about in the world that offer opportunities to learn about the fundamental mechanics. Reality is much more in-depth and also (at least seemingly) much more complete in that regard.

    • @@fexus9730 Since ancient times up to this day, most thinkers share the intuition that the number of interaction categories in the (inanimate) physical world might be limited; some go a bit farther, also saying that the observable interactions might only be a subset of all interactions in our universe. On the other hand, simulated worlds don't have such limitations: their size, scope, variety of interactions can always be e.g. procedurally or stochastically expanded, they can be made virtually endless, only limited by available memory for certain interaction categories. The contrast between the former intuition and the latter fact is remarkable.

  • I would say holographic duality best explains this. There’s a world of quantum interactions without gravity and this quantum world contains a full description of things like general relativity. So the classical world emerges from these quantum interactions. So the classical universe is a holographic projection of information in 1 less dimension without gravity.

  • Could the mathematics of quantum mechanics represents the physics of time, with classical physics represents processes over a ‘period of time’ as in Newton's differential equations? The spontaneous absorption and emission of light photon ∆E=hf energy or quanta is continuously exchanging potential energy into the kinetic Eₖ=½mv² energy of electrons. Kinetic Eₖ=½mv² energy is the energy of motion of what is actually happening as an uncertain ∆×∆pᵪ≥h/4π probabilistic future continuously comes into existence with each photon electron interaction or coupling. In this theory photon energy (quanta) are not a property of space and time; it is the other way around the characteristics of time and structure of three dimensional space forms out of an exchange of photon energy. The spontaneous absorption and emission of light quanta forms the continuous motion that we measure as the passage of time.

  • The Rosetta Stone of quantum mechanics is made of a substance called nitrogen tri-iodide. Just two molecules of nitrogen tri-iodide can make up an alpha particle detector in the classical sense. The interaction between an alpha particle and these two molecules involves a radical destruction of unitarity, which I propose could be modelled in a computer simulation by adding what I call tachyonic Brownian motion, though other ideas are most welcome. These two molecules are the smallest possible detector, but their computer simulation will require at least 24 dimensions of configuration space just counting atoms alone. This is not possible. What we can do instead is to model a detector using classical Brownian motion. This is decoherence but with tachyonic Brownian motion as a proposed aetiology.

  • I would sort of agree with Penrose that's its not just down to "consciousness" wave collapse. there's a necessary entangled component, re hidden variable, NON LOCAL. It takes two to tango. I discussed a symbiotic type of wave collapse once with David Chalmers in emails in the 2000s, where the object of our desire so to speak, beckons to be better defined, so the observer and observed need to sort of acquiesce to create REALITY, an entangled non local process. But it still requires a check for either "consciousness" (whatever that entails) as a minimum and perhaps as i am starting to suspect, a UNIQUE soul...in other words entangled to source/issuer and no COPIES in existence, this is key. Clones don't SURF! (waves) The triverse wont allow it.

  • It's a QCD weaved Neutrino Ocean under electron excitement, one resonant in phase wave pressure. The other, resonant in evolving transversal energies. Together they create our space-time as we see it. Gravity is still in part refractional displacement, but at the neutrino and electron level (elementary particles) it involves phase states and neutrino oscillation/concentration/energy or wave phase state/conditions. We phase as a part of this. We do not understand this process. The measurement isn't the refractional property..it's in using photons (always) for making observation. The set refracts in each direction of time and paradox with every electron/photon invasion. Neutrino Ocean wriggled in resonant nuclear chromoelectromagnetic resonation concentrations, both entropic in nature, together evolving inverse to both entropic entities in refraction

Gravity is very different from the other 3 forces, so better understanding of that is crucial. The standard model of particle physics is clearly not the final answer with 20 free parameters. As for many particle emergence, statistical mechanics is well known. To be sure, the next level of theory will be just that, at another level. My guess is that both dark energy and dark matter will be out.
