    Since neutrinos have mass, they only travel at less than the speed of light. This means you can find an inertial reference frame that overtakes a neutrino. From that reference frame, a left-handed neutrino would look like a right-handed antineutrino traveling in the opposite direction. In one reference frame you have a neutrino. In another an antineutrino. This paradox would be a good topic for a video.

    The claim that there must have originally been equal amounts of matter and antimatter is itself dubious. We don't know what caused the big bang, we don't know what should have resulted from it. It is assumed that the universe was created with equal charge but that is an assumption, it has no empirical evidence. The ratio of matter and antimatter could have been an arbitrary parameter of the big bang.

    Is there any potential relation to the flipping of chirality of neutrinos/antineutrinos and the Dzhanibekov effect? I know it couldn't literally be the same phenomenon, but perhaps an analogous effect takes place in moving neutrinos...but because they travel very close to the speed of light, the occurrence of such flipping would, to outside observers, be much rarer than might be predicted from the point of view of the neutrino itself. I don't know whether that is potentially sensible or way off base.

They are the real particles, but we only detect the mixtures that are flavor eigenstate. In the quark sector its sort of the converse, the weak interaction only interacts with d' and s' quarks, while we think about d and s quarks. ofc, being quantum, we could just as well mix them via u and c, so it's really just convention.

    I don't think there's any unanswered question about neutrinos more interesting than the overtaking problem. Helicity is measured relative to the direction of travel. Since neutrinos have rest mass, they travel at less than the speed of light. Suppose you see a neutrino go by at 0.9c. You observe that it has right helicity, meaning it's an antineutrino. You then jump in your spaceship and accelerate, chasing the particle. At some point your speed relative to your starting point exceeds 0.9c, which means in your frame the particle is now traveling in the opposite direction from what it was before. But its spin hasn't changed, which means its helicity has flipped to left. But that makes it a regular neutrino, not an antineutrino. Did you just convert antimatter into matter simply by changing your frame of reference? If so, what does this imply for relativity? And how do you reconcile what you're seeing with observations by your colleague back home, who still sees an antineutrino?

    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. 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 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.

    What if neutrinos are opposing like north and south poles rather than positive or negative? Your input wouldn't cancel out, they simply combine. When they combine that wouldn't need to be double strong. Rather they could be weaker or stronger as the distance between poles changed. Every neutrino may have mostly north charge. Throw enough energy into and the result may flip the pole. To visually see my idea you can use two common ceramic magnets and a 100mm long piece of steel bar. Take one magnet and stick the north pole onto one side of the bar. Flip the bar over and stick the second magnet on the opposite end of the bar with its north pole. At first the magnet will oppose doing so but trust me, it will hold once in contact. You now have a s-shaped array that exhibits mostly a single north plle and two small and weak south poles. I know its strange but it has everything to do with combined magnetic flux. Take a third magnet and you will see its true, as its still has one big north pole and two small south poles. A neutrino may be something akin to this, only the forces are more uniform. And since the poles are not symmetrical you mostly repel but when the weak pole is at the correct position they attract. Destabilize this uniformity and poof, they now interact with a neighbor. Now take a second bar and attach the south poles. Same pieces, reverse characteristics.

    Maybe, when considering the expanse of spacetime between the big bang and the end of the universe, it still adds up to nothing. Then, it's just a matter of perspective that there appears to be something. In our case it's in the far tail of the distribution (14 billion years or so), where there's barely anything but self sustaining processes remaining. The implication being there's an equally unlikely negative something on the other side of the mean. Unfortunately in this view we're all just waiting around to eventually be cancelled out by our own anti particles. On the other hand, the nice part is there's any number of solutions, and the accounting is especially useful. It's conserved. Thinking in a top down manner in physics is a new phenomenon, as before not too long ago there weren't any CMB or Uncertainty Principles to constrain us. I wonder if we're getting close to making some different kinds of universal assumptions and implications given these imposed restrictions. I've seen some talks from Neil Turok that seem to be asking some of the same questions, and he's saying right handed neutrinos are a potential solution to a lot of problems in physics. I'm not a great particle physicist, so I'm not sure what to make of it! I guess we'll have to see where the experiments lead us.

    1:08 Steve Biller ... there just one problem it gavetwo solutions for energy. So this happenswith a quadratic equation. Dirac's equation was quadratic in energy so you could have a positive energy solution and a negative energy solution. Son in this sort of thing happens in physics, we tend to just throw away the nonphysical solution and keep going. But Dirac wondered whether the negative energy solution could have a physical interpretation, and that led him to postulate the existence of antiparticles. So nowadays we don't think antiparticles as having negative energy, but think those particles that have their fundamental properties reversed. And amazingly, a few years later, in 1932, the entiparticle to the electron was discovered, the positron which looks identically like an electron, but with a positive charge. 2:00 ... 4:09 There's a problem with the universe. When it was created, you must have had equal amounts of matter. 【Nature has no problem at all but physicists have big problems for their interpretions of cosmic microwave background origin and their ideology.

    Why would it emit a photon? I don’t think neutrinos interact with photons. If it emitted a photon, then I think that would imply that neutrinos could also absorb or emit photons. Actually, I think maybe only charged particles can interact with photons, for symmetry reasons? Now, what happens when an anti-neutrino and a neutrino meet, if they don’t annihilate and produce something else? I think maybe (this is speculation on my part. I don’t know.) the idea it isn’t exactly that they meet and annihilate, so much as that the creation of the one, is the annihilation of the other? Like, if the decay of neutron involves the annihilation operator of the neutron, the creation operators of the proton and electron, and the creation operator of the neutrino, And like, the decay of two neutrons have two of each of the above, with all these operators multiplied together, that the two copies of the creation operator for the neutrino, cancel out, because of the creation operator and annihilation operator of the neutrino, being the same operator? Like, photons are also their own anti-particle, but you don’t have a situation where two photons annihilate with each-other and emit a photon.

I guess if an electron and positron correspond to representations of exp(i theta) being sent to exp(i theta) and exp(-i theta), and these together making the trivial representation, then these annihilating to form a photon, should imply that the photon’s associated representations of U(1) should also be the trivial representation, So my reason for thinking that U(1) symmetry requires that photons only interact with charged things, didn’t make sense, I suppose.

    Spin is real and is caused by an imbalance in the vectored momentum of incoming and outgoing superluminal fundamental particles. Spin itself is superluminal and is only dependent on the direction of travel by an instantaneous flip of a particle to align its poles with the other particles in the stream. This means that there is some small immeasurable charge on neutral particles like neutrons and neutrinos with charge representing a quantised net difference in the number of incoming and outgoing superluminal fundamental particles.

    Neutrinos are notoriously difficult to detect. We're told they can pass through light-years of lead. And that some ridiculous number of them pass through us every millisecond. So I presume that in most normal beta decay, including double-beta decay, the neutrino(s) would escape undetected. So how do you distinguish between a neutrinoless double-beta decay, and a normal double-beta decay in which the neutrinos escaped the detector undetected?

This only an effect of a resonant phase wave neutrino ocean. That's right.

The forces converged to evolve inverse to the neutrino pressure and refraction properties. Likely responsible for resonant pressure holding (possible in part condensing to ignition) fusion reactions together like the Mariana Trench might under thesam3 conditions for a fusion star the size of a grain of sand. The resonant transfer is everywhere we look. It's why the math even exists along with paradoxical choice and the QCD energies in part.. nuclear electrons in tunneling resonation whips as pairs converging to evolving inverse to the neutrino pressure and with strang3 attractions and von Karman Vortex streets, properties of flow and eddy, cymatic nature, entangled fields, and electromagnetic wave particle dual electrons helixing, Vortexing in convergence as pairs emerging, another pair meeting as inverse in description and orbiting and exchanging energies inverse to there relative properties of movement and energy exchange, needling casting to evolve whip lighting as tesla coil like field excitement, careening off in amazing resonation wiggle to a needling point like particle, likely engulfing and flipping through and/or around atomic nuclei and black holes or other Heaney bodies with enough energy concentrations like possibly around fusion reactions. Perhaps stars are their transformers.. us and nature a product of their awesome evolution to spin inverse energy sets with infinite potential into reality as we know it. Our current likely surging to their tunneling or resonation paths. This like,y or not, the uncertainty principle and wave functions speak loud in a direction that we too are in superposition, but only experience a flow. BET anything.

    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. Virtual particles may power beta plus decay. 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.

    If the neutrino oscillation depends on the magnetic field strength, then a neutrino energy absorber could be created in the laboratory, which would be a better producer of green energy than thermonuclear reactors. Maybe it is the energy of oscillating neutrinos that heats the solar corona to millions of degrees in the magnetic field. If people manage to achieve a magnetic field of 1000 Tesla in the laboratory, I think it will be enough for neutrinos to oscillate every few meters from an electron neutrino to a tau neutrino and release energy, returning to the electron neutrino state again. Under the conditions of the Sun's magnetic field, neutrinos oscillate approximately every 300,000 km.

    @@ozzymandius666Do you understand QED? I don’t, so I’m not saying like “I understand QED and here’s the sense in which bla bla”. I have some impressions of the math in QED, but, I don’t really know it. In the Klein Gordon equation, the solutions include momentum eigenfunctions I think, which are functions of space and time, oscillating both in time, and in space. But, like, moving along any line in spacetime, this oscillation is just a phase factor? And, phases factors themselves aren’t observable, only relative phase factors, yeah? I think the Klein-Gordon equation is only for massive particles, but I’m going to imagine that something similar to what goes on with the momentum eigenfunctions is also applicable for photons. I imagine that when photons “oscillate”, (or, perhaps I should say that the electromagnetic field oscillates(?)), it is a thing like this, with like, interference changing as the phases change across spacetime. With neutrinos... Ah, yeah, I think that if the 3 flavors each had zero mass, then, if it had the same kind of “linear combination of eigenfunctions of momentum”, I would think that, if the linear combination was purely one flavor at the start, then if they were moving at c, then the dot product of the momentum and energy with the difference in spacetime positions would be the same for each flavor, and, like, you wouldn’t get different changes in phase for the different flavors? And like, there wouldn’t be a mass basis for the 3. The different flavors would just stay separate? So you would always end up with the same flavor at the destination as at the start? Of course, like, I’m waving my hands a lot because there’s a lot I don’t understand/know here. But, If the state of a neutrino can be expressed as a linear combination of momentum eigenstates, and if the momentum and flavor operators commute, then, if they aren’t interacting with anything, just being free massless particles , with the energy being determined entirely by the momentum, Then, there should be no mixing of flavors; flavor would be conserved. ;Oh, also, if there was a contribution to the energy other than from the momentum, outside interacting with other things, I would think that would produce a rest-mass.) I think that is fairly compelling reason to think it makes sense that that their being massless would conflict with the oscillating between flavors. But, of course, I don’t really know QFT, so this isn’t a complete mathematical proof like you requested. But, it is some ideas which I think gesture towards the real mathematical reasons, as best as I can tell without really knowing QFT.

    Okay, I will attempt to explain it again. The word oscillation the way you are using it for photons means something different than what is mean by oscillation when talking about neutrinos. The EM field oscillates, not the photons. The oscillation of the EM field is the photon. "neutrino oscillation" doesn't refer to the quantum field associated with a specific neutrino field oscillating. For the next part, I will try to stay technically accurate, without bogging you down with too many details, but ultimately any explanation fails apart from the mathematical model itself. "neutrino oscillation" refers to a very specific phenomenon related a certain set of field interactions that in turn correspond to specific terms in the equation that describes the standard model. Due to reasons of unit consistency (the physical units have to match up with each other in the equation) these specific interaction terms require that the rest mass of the neutrino be multiplied with them otherwise the units would turn out wrong. The argumentation isn't as simple as that. But it is more or less true( and it is absolutely true that every term in the equation has to have the same units for it to be a valid equation). Since photons (and all massless particles) don't have a rest mass, they can't have these terms and thus can't experience a phenomenon similar to neutrino oscillation. That massless particles "don't experience time" also has to do with what kinds of particle interactions are in principle allowed by the unit consistency I mentioned. And massless particles end up being very restricted by this as to the types of things they can do.
