Quantum Entangled Twisted Tubules: 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. (More spatial curvature). 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 actually a part of the quarks. 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" make sense based on this concept. Neutrinos would be made up of a twisted torus (like a twisted donut) within this model. 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. 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. Gamma photons are produced when a tube unwinds producing electromagnetic waves.

[@SuperFunniestvideo]

Great video. Is wikipedia right? - "The strong interaction is observable at two ranges and mediated by two force carriers. On a larger scale (of about 1 to 3 femtometer), it is the force (carried by mesons) that binds protons and neutrons (nucleons) together to form the nucleus of an atom. On the smaller scale (less than about 0.8 fm, the radius of a nucleon), it is the force (carried by gluons) that holds quarks together to form protons, neutrons, and other hadron particles"

[@ArvinAsh]

Great question! Sounds about right. The force mediated by gluons within nucleons is called the Strong Force. The force mediates via mesons is a residual form of the strong force, called the Strong Nuclear Force. Coincidentally, I will be posting a video on the latter, which is mediated by Mesons, this week. It will be very detailed, and I think you will enjoy it. Stay tuned for the July 29 premiere.

A video like this one is much more helpful than it all on a blackboard in a classroom or church.

Sometimes when plants outside wither, they change color unless they are evergreen, but that is different in quantum perception. Lions may yawn, but to someone who cannot hear, it may look like they are roaring. It is funny how things are illusive in different ways, like the rainbow which I have yet to find any pot of gold at its end. But, Arvin Ash you are helping us all to understand some interesting ideas in these days before each a darkness is realized which ends it. The frogs sing at night, but I am not sure that their songs have the same carrying on as the knowledge which you present to your viewers.

I do understand that gluons carry color-charge, it is a bit more complex than RGB, but good enough. Imagine red gluon emited from quark, changing its color, hitting another quark in a proton, restoring color-neutrality. That is what glues them together. Won't work outside a proton, but pulling the quark out creates meson (quark+anti-quark) that later collapses (matter+anti-matter annihilation), but still transfers momentum like the photon to mediate strong force (photon mediates el.mag./electro-static ... don't get me started about relativity here).

For a single photon that gives you zero, but not for two photons. You’re right that the binding energy of an atom adds (actually subtracts!) to its mass.

There must be quantum love ...😅😅

[@SernasHeptaDimesionalSpace]

love with in particles.

[@SernasHeptaDimesionalSpace]

@@Gogoi-5629 so much mass and so much love.

[@ArvinAsh]

Spoiled again...by love!

The Love eqn := V (LoveU) x Long2 x time

[@richardmcsweeney5291]

best explanation of this perplexing sphere of atomic mechanics ever, well done, i almost understand

[@hgfuhgvg]

I read the title as "OCD: the strongest force in the universe", which also seems legit

[@MathAdam]

Beat me too it.

[@99dudette]

Brilliant video, the best I've seen on QCD Thankyou

[@ArvinAsh]

Glad you enjoyed it.

[@terrylewis4230]

Does anybody remember Newtons laws of physics ?? For Every action there is an equal an opposite reaction.

[@TheOnlineBlackboard]

It's called Rocket science :D

[@terrylewis4230]

Only if u in grade 7 🤣🤣🤣

@Prerit Sharma this isn't universal amongst schools, idk why you're trying to correct him. I've learned of this stuff in 4th grade.

@@daenite2480 bro you were 10 then did you even know what force was except the magic in star wars

[@daenite2480]

@@TheFlemishNut for one thing: 9 for another: didnt even like star wars and finally: you *severely* underestimate the intellect of a 9-year-old if you think this is borederline impossible to teach them, unless your school just so happened to underperform in educating their elementary students.

[@paulg444]

Arvin just hit it out of the park!.. very impressive explanation.

[@usama57926]

Why gravity considered as one of the four fundamental forces. Because general relativity proved gravity is not a force. Its just curvature in spacetime

[@ArvinAsh]

...because GR is incomplete, and its true nature is not really known. It may yet be found to be a force after a quantum gravity theory is discovered.

[@starman2420]

Excellent presentation. Thank you Arvin Ash.

[@KilgoreTroutAsf]

4:25 the fact that you can infer a force nobody has yet detected and estimate its properties from such a straightforward chain of reasoning is just astonishing

[@lewrich4]

You make it all sound so easy. Your a excellent teacher.

[@roxakchan]

My 4 and a half yr old loves your videos. He wanted to add a comment, and asked me to ask regarding the content of this video: “How does this all happen?” :)

[@ArvinAsh]

Well, that is one smart 4 year old! It happens due to the nature of the color charge. When two objects with color charges are nearby, they interact in such a way that the contents of this video illustrate. What exactly is the nature of the color force is not known...but this would be a great thing if your 4 year old would study it, and perhaps provide a new insight for the rest of humanity.

[@cosma_one]

So let's see if I got this straight. In order for the neutrons and the protons to stay close together in the atom's core, you need to have Pions, which come from quarks that were detached from their proton/neutron and formed a quark/anti-quark pair. Assuming I got this correct I got a few questions: 1) How do these Pions mediate the strong force between nucleons? Does each quark in the end of that Pion attract other quarks inside the nucleons thus pulling them close to the Pions and thus bringing the nucleons together? Do Pions interact with each other to create some effect that ultimately draws the nucleons too? 2) What happens to the quarks that break from a Pion? Do they form another Pion (quark+antiquark) or do they from a pair of either quark+quark or antiquark+antiquark. If these homogenous pairs are created what happens to them, next? Do they play a part in the process of drawing the nucleons together? Do they serve any purpose in general? 3) And my final important question: what causes the quarks inside the nucleons to break free from it, in the first place? Who pulled them out? Where did the energy come from?

[@neonsilver1936]

That was the most helpful and informative introduction video to QCD that I've seen yet. I am still trying to wrap my brain around all of this, so maybe it's just that something finally clicked because of your wording about the color charge. I still don't fully understand color charge, but that gives me a direction to keep learning. Thanks, man!

[@ArvinAsh]

Glad it was helpful! Color charge is something that no one yet understands the true nature of. We just know what it does, and how it works.

[@Yk-kj6ly]

I learned more about strong nuclear forces through these videos than by physics textbooks. You are a great Teacher!

[@robinrobinson6714]

Bless you Arvin! Thank you! I finally got it!!…, such a EXCELLENT video!! A Metaphysician HAS to have a good understanding of Physics nowadays. And thanks to you, I don’t have to become a Mathematician (even though I actually understood the math!!). Again, thanks!!😊👍

[@rmehta54]

Brilliant!! When explained, like this, it is easy to understand. Thanks Arvin.

[@misterschifano]

This was pretty exemplary. There isn't much else to discuss here without delving into the math. Well done, sir.

[@ebaymoncton]

I enjoy that this is just out of my grasp of understanding until I listen a few times. Next level stuff for me. Thank you Arvin!

[@twistedtim1969]

This video has raised my understanding of color charge and the strong nuclear force tremendously. Thank you!
