What happens if you join the head of your paper arrow to the tail of your paper arrow, as in a torus? What if neutrinos are a torus with either a RH or LH twist and antineutrinos are a twisted torus with the opposite twist? ---------------------------------------------------------------------------------------------------------------------------------------------- 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. ------------------------ 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. 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. 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. 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. .

[@ivangaeta4126]

In my nuclear physics oral exam I was asked about this experiment, and I answered using the explanation given in this video. My teachers said that it's really difficult to explain it in a clear and concise way, but I did it. Thank you very much

[@markl4593]

Dear Mr Das, What a superb follow up to your “What are Neutrinos” lecture. I especially loved your explanation of the Wu experiment. I very much respect your ability to present quantum concepts in understandable explanation - you do share that trait with the great Richard Feynman.

[@FortheLoveofPhysics]

Thank you.. I am very flattered by such high praise :) I am glad you enjoyed the video

[@FortheLoveofPhysics]

UPDATE: So here's the video on Neutrino Oscillations, finally :) kzbin.info/www/bejne/oJLQn4mAa9pkrbs I promised a video on neutrino oscillations. However, i am a bit stuck on a few animations (which i wanted to create for a better visualization of the topic) so till i figure that out, pls enjoy the other videos. Cheers :)

[@arzooakhtar5225]

OK sir. I'll wait for it. But you are doing great work keep it up sir. 👍

[@ambitiousshouryasharma3173]

Tqq so much sir particle physics content on KZbin is not much in number so u r initiative is really appreciable

[@henryD9363]

Only my opinion but I would say You are already very good at explaining things with your chalkboard explanations. Don't worry about animations. Often they are over simplified and give and incomplete and misleading View of the physics. This is especially true in the case of a complex probability amplitude function that is represented using an image which is naturally described with only real number dimensions. For example, I don't know how you could animate the probability amplitude function for a photon in the double slit Experiment. The very act of showing an animation implies a measurement of it as it moves forward in time. Looking at it destroys it from the very beginning. I would like to be proved wrong it's this would help in the understanding. But I don't see anyone has done it

[@FortheLoveofPhysics]

@@henryD9363 Thanks.. I think you have a point there!

[@eliagiuliograndoni2898]

This video helped me with my thesis for bachelor degree in physics, beautiful and clear explanations.

[@darmstadtbeste4590]

We had to read the original paper of the Wu experiment in our Particle Physics Master course and I didnt understand much while reading it, but with your video its totally clear to me and I finally understand why this experiment was so groundbreaking. Thanks a lot !

[@henryD9363]

Thank you so very much for this detailed and clear explanation of the violation conservation of parity. This is so helpful. It's the first fully COMPREHENSIVE explanation I have heard. It was detailed, step-by-step, and clear all along the journey. You did not skip over or rush through the important and difficult aspects, which is something that happens all too often in technical lectures.

[@shishirjha7744]

Perfect clarity. Please keep on doing. How sad that Wu did not get the Nobel she so much deserved.

[@Harshit-lh8jz]

The Best explaination ever ! Thank u so much sir for such an informative and lucid explaination . ♥️

[@alexiaalexanderwight1199]

This is really really interesting. Can't have imagined a better physicist to explain this!

[@Sahil-bb2qw]

I thank you from the bottom of my heart for the series you are doing.

[@socialreveluv5428]

After a lecture I always come to this channel to get another glimpse on the topics of particle physics. It has been the most reliable source which is also easily understandable compared to some books. I am really grateful that I can live in a time one can benefit from videos like these.

[@ghanshyamgautam2603]

The best i have heard for this topic. One of the finest explanation..! God bless you

[@blitxaac]

I was struggling a little with this concept, but man you explained it in such a concise and detailed way. Thank you very much!

[@bloodyorphan]

It is a stability question, we have long known there is no requirement for any collision to occur for a particle to form. Particles persist even after their velocity drops to zero m/s. Particle Persistence symmetry is based on the Standard Particle Physics Laws, but the symmetry is energy based, not "LAW" based. I.E. The speed of light is not constant , it has been observed to be 1.3c in a 10,000 degree Celsius space. **EINSTEIN**

wah bhai kya explain kiya hai, gajab

[@mrfinesse]

Wonderful video as always. Thanks very much again. This is the first time, I've been able to understand clearly what a mirror image/transformation means. I was under the assumption that in a "Mirror" Universe, you have to flip the charges as well (Electron becomes a positron), and a particle becomes an Anti-Particle. Perhaps that is a different set of transformations. Thanks again for very clear explanations.

[@FortheLoveofPhysics]

Indeed, what you are referring to is CP (Charge+Parity) Once P-symmetry was violated, it was believed that CP- symmetry was conserved instead. But that was shown to be violated too, leading to CPT

[@vikaskadian461]

Great lecture.... Really brilliant...

[@danmiller4725]

If you make a fist with your right hand and look at how the fingers curl on the backside the little finger curls clockwise. On the thumb side the forefinger curls cntrclkwz. Yet the fingers all curl toward the palm. So opposite curls clockwise and cntrclkwz are not essentially different. Given momentum the two opposites are helical and clockwise and cntrclkwz are essentially different and nonsuperimposible. This needs review by the physicists.

[@ghanshyamgautam2603]

This was one of the finest (i just revisited this lecture) the explanation to preferential outcome of electrons was explained nicely. My only question that remains unanswered is why can't we simply see the parity violation by observing only beta decay rate?

[@nikkanbiswas3357]

Very nice explanation.....

[@SimranKaur-nl5yp]

Super lecture.. thankw sir

[@RajarshiGhoshal]

Wonderful! Thank you!

[@PasseScience]

Hello, let's say we have 2 versions of an experiment, a left version and a right version (parity symmetric) and let's say we observe a different behavior in each (a non parity symmetric behavior). It can be due to 2 differents reasons: a) we forgot to make symetric the "inside" of a component by wrongly assumming it was "atomic" or b) the laws of our universe violates the parity symmetry. It's unclear to me how we know that we are in the case b for the Wu experiment, how do we know that the cobalt atom is not just an asymetric structure that we "forgot to miror" ? how do we know for sure that we are not lucky to observe only right-cobalt in a universe in which there is in fact left-cobalt as well ?

[@DrDeuteron]

He left part of the experiment out. He shows 60-Co --> 60-Ni*. The star means the nickel nucleus is excited. It immediately decays to 2 gammas with a known quadrupole alignment (a quadrupole is parity even). The distribution of gamma rays allows one to measure the alignment (but not direction) of the 60-Co spin. Any asymmetry in the electron momentum with respect to _either_ direction associated with the alignment violates parity, so it doesn't matter if you got the cobalt spins reversed. Scalar probability being proportional to the pseudo scalar dot product of spin and momentum violates parity.

[@NikitaSharma-jg1mu]

Wowww👌👌

[@HimmatBording]

Wow. The most interesting topic is here.

[@rittwikchatterjee5347]

Superb sir🌸❤️

[@bishwajitbhattacharjee-xm6xp]

The symmetry of parity in quantum particle nicely put in vector signature. Your good teaching never forget to mention "intensic" property as well a not real or physical rather a mathematical operations only. Then why violation under a force field physics taken seriously . Collapse of wave function is not a universal fact . Please see in more depth in future planning on quantum mechanics. Computing is different than physics or nature.

[@johnsmoak8237]

Allegedly it was recently disproven that gravitational forces arent capable of measurably violating CP symmetry Luckity T is still here to hold things together 🤣
