This isn’t physics. This is abstract maths that has no bearing on the physical world

[@michatarnowski580]

It’s a legitimate mathematical question how much can string theory explain, and the possibility of explaining the number of macroscopic dimensions sounds impressive. Maybe it’s an argument for string theory’s validity, maybe not, but I don’t care to be honest - it’s all very hypothetical anyway. But I still want to know how much can be explained, so I believe this line of research to be at least as valuable as pure maths. Maybe string theory should be moved to maths departments or even to philosophy departments, maybe more should be invested in other theories of quantum gravity, but constructing explanations is fruitful. I believe developers of different models should be considered collaborators, not rivals. They're like astronomers looking into different parts of the sky, exploring worlds that will never be touched. The question is whether we should focus on worlds which are close to us or on those which are particularily odd and potentially surprising.

[@hayatojp1249]

is it possible to consider weird quantum phenomenon as other dimensions that we can not see or experience?

[@146maxpain]

Problem is that the Large Hadron Collider has not verified super symmetry.

[@debtanupatra3385]

It only verified supersymmetric nonsense.

[@youtubesucks1885]

Low energy supersymmetry is ruled out. However, this is not prediced by string theory. What is predicted is that the low energy effective actions of string theories are supergravity theories and they are high energy supersymmetric.

I’ve been hearing about string theory my whole life. I don’t know anything, but I’m suspicious when-after all this time and collective effort-all he can say is “the math is beautiful”.

[@advaitrahasya]

Gurdjieff tried to explain the physical mechanisms of strings, but, on account of using the word "hydrogens" to talk about modes of vibration, he could not be understood. This was on account of him hearing that science had discovered the most fundamental matter and had given it that name. He thought that they had discovered the primal vibrationary mode, so he used their word "hydrogens" meaning "vibratory modes". Strings, like the other tweakable mathematical models from QM to QED and GR are "blind men's reports of the elephant" as spear, snake, fan, barrel, tree and whip. The reason the views taken all miss the elephant itself is the blindness. Blindness is created by paradigm. Geocentricism blinded us to planetary orbital dynamics. Chronocentric Atomism blinds us to the fundamental. Escape Chronocentricism and Atomism … strings will have a physical, mechanistic explanation. The cyclic rise and collapse of the not-exactly-zero volumes of strings yields gravity. But escaping atomism is hard. Some hints/encouragements: Notice that string theory maths are really useful to hydraulic engineers. Take the Young's modulus of "empty space" seriously. That which we call "empty space" in the atomistic model is 20 orders of magnitude stiffer than diamond. If that doesn't help, take an afternoon to smoke a cigar, blow smoke rings, and gaze into a glass of champagne.

[@FordFourD-aka-Ford4D]

Seems like you're hinting at something… why don't you just outright say it?

[@advaitrahasya]

@@FordFourD-aka-Ford4D Invert atomism. Instead of bits of somethingness bouncing around in a nothingness … "matter" is "strings".. threads of pure vacuum spun open by generally toroidal vortices. Spun open from the one indivisible substance, probably best modelled as a superfluid/supersolid. Interlinking and knitting toroidal vortices are interlinked centrifuges. thus gives them momentum Collapsed by the vibration/impulse of the high pressure moment … reappearing probabilistically in the low pressure moment. That repeated collapse of matter yields the motions/force called gravity. .. about as direct as I can be. invert atomism .. even if just as a thought experiment.

[@SpotterVideo]

Conservation of Spatial Curvature (both Matter and Energy described as "Quanta" of Spatial Curvature) 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 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. ----------------------------------------------------------------------------------------------------------------------------------------- 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 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. Quantum Entangled Twisted Tubules: “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 the “Twistor Theory” of Roger Penrose, and the work of Eric Weinstein on “Geometric Unity”? 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 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 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 Mesons. 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. Gamma photons are produced when a tube unwinds producing electromagnetic waves. 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. We know there is an unequal distribution of electrical charge within each atom because the positive charge is concentrated within the nucleus, even though the overall electrical charge of the atom is balanced by equal positive and negative charge. >>>>>>>>>>>>>>>>>>>>>> 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. The 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. .

"Take a random dimension from 1 to infinity." It's strange how he takes a theoretical concept - dimensions - and uses it as something real. Mathematicians come up with some math, call it a dimension and we are supposed to treat is as something real. I do admit that I need to educate myself on what dimensions exactly are. That said, I would be very surprised if dimensions beyond the 3 "classic" ones weren't created by a mathematical sleight of hand.

There is a thick line where both physics and metaphysics seem to overlap, there is no clear boundary! You know Newton's physics just worked and seemed to be experimentally verified until proven to be only an approximation - a really useful and elegant approximation, but the more accurate physics needed much more effort to be proven and was also frowned upon in the beginning. My largest concerns are about the utility of string theory (e.g. compared to Newton's physics). With Newton you can build (better) machines (right now), with string theory, you can justify more obscure maths. It remains to be proven really useful, such as the updates to Newton by Einstein et al.
