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? 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? 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 Force" 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 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. >>>>>>>>>>>>>>>>>>>>>> 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.

Atoms are neutral in charge. Since electrons having negative charge are revolving around the nucleus so there must be equivalent positive charge in atoms. These positive charges are protons.
Protons are a fundamental part of the Nucleus. And even if we become successful in removing the protons from the nucleus, it would make the nucleus unstable(claim). Now if the nucleus doesn't has electrons to interact with other atoms, how will it regain its stability? And, regarding your question that why a nucleus having only neutrons is not available, is because we haven't found such a nucleus that does. Still, I haven't answered your question. Now why haven't we found such a nucleus? Because the micro universe doesn't work like that. I hope I answered your question. Thank you for reading.
Your question can simply be rephrased as "Why do we have Atoms". The thing is, Atoms exist because of the interactions between Electrons and Protons within the Atom itself; without which such configurations of particles in the Atom can not be achieved, even if it is achieved by chance it would still be fragile. For a better understanding, read something about "Particle Interactions at a Distance", then you will understand that Atoms exist because of the nature of particle interactions in their configurations. So getting back to your initial question, " Why a nucleus having only neutrons doesn't exist", I would say that the neutron lack charge (i.e. they have a neural or zero charge), therefore can not in any way interact at a distance with the electrons to form the configuration of an atom (which consists of a Nucleus and Electrons around it). Simply put, we know that electrons are electro-negative, the presence of a positive charge in the nucleus (proton) makes it possible for the electrons and protons to interact (through an attractive coulomb interaction) thus maintaining a level of "Togetherness". However note that my explanations are only basic illustrations for your convenient understanding. You need to clear all your doubts with quantum mechanics of the "Hydrogen Atom" to better understand why the electron doesn't collide with the nucleus (especially the ground state -> n=1 electrons -> 1S orbital) if there exist such electrostatic attraction forces in the Atom. Or why the electron doesn't loose out all its energy (through photon emission) as it orbits the central positive nuecleus, hence colliding it. Thanks for your attention.
He got this idea because the electrons are not collapsing into the concentrated nucleus even when they are of opposite charges. thats why he came up with the idea that the electrons have to somewhat move around the nucleus in such a way so that elctrostatic effect is nullified. This what HC Verma said in the video. Pls rewind through the video and confirm, then only believe what i said above is right. Thank YOU.

How electrons can repel alpha particles since alpha particles are positive charge and electrons are negative charge they should attract towards them
Anyone made notes of this entire lecture, please reply, i need it
Great sir
Can 12 can Student take help from that video
As we all know rutherford suggested the model where electrons have tk revolve around nucleus. My question is from where he got this idea?
Might he had noticed negative charge around atom
He got this idea because the electrons are not collapsing into the concentrated nucleus even when they are of opposite charges. thats why he came up with the idea that the electrons have to somewhat move around the nucleus in such a way so that elctrostatic effect is nullified.
This what HC Verma said in the video. Pls rewind through the video and confirm, then only believe what i said above is right.
