Super well researched! But you might want to be careful with throwing around that neutrinos have "antiparticles", as that's still an open question. A lot of particle physicists think that they might be Majorana fermions, which means that they are their own antiparticle, and if that were the case it would also help explain the mass issue.

One fact I always thought was fascinating is that 99% of the energy released by a supernova is in the form of neutrinos. That’s “gravitational energy”, which I think I understand to mean that 99% of the energy thrown out of the star is in the form of mass as neutrinos with their kinetic energy. That’s in contrast to the amount of energy released as photons or more familiar subatomic particles such as protons, neutrons, electrons. Neutrinos are obviously subatomic particles, too, but it surprises me that they contain most of the energy released in a supernova.

The natural first (Occam’s) assumption to explain how or why a particle like a photon (or electron, etc) might behave as an uncertain location particle while also like a polarizable axial or helical wave “packet”, given that everything in the universe from electrons to solar systems are in orbit with something else pulling them into polarizable axial or helical apparent waves depending on the orientation of their orbits as they travel thru space, and given that we know we’re in a sea of undetectable dark matter but don’t know where it’s disbursed, is that they’re in orbit with an undetectable dark matter particle pulling them into polarizable axial or helical apparent waves as they travel where the speed of their orbit determines the wavelength and the diameter is the amplitude which would explain the double slit, uncertainty, etc.

One interesting thing to note is that in order to get massless energy waves to become mass particles, mass would have to derive from the energy waves interacting more with itself, perhaps with another complimentary energy wave, creating a pairing up of sorts that creates energy fluctuations that travel within its own construct, in other words it goes in 'circles'⭕ Ah yes mass is just sass, In other words the more the energy is interlocked in an arrangement, the more stable mass seems to become? Would this hint to an even smaller construct of near massless particles

The implication is that matter is time encapsulated. Time is a variable in the equations that express properties of energy and matter.

6:29 The standard model doesn't explain gravity, but I'm really fond of the explanation that gravity isn't a force but just the consequence of inertial motion within curved spacetime.

I wonder if gravity and spacetime are opposing forces, but are tightly intertwined... if only we could see the singularity of a black hole. Who knows if understanding neutrinos would tell us about singularities?

Firstly, neutrinos were proposed by Dirac. To balance equations that model neutron decay he needed a massless term that had spin. Several decades, and lots of money was spent trying to physically detect these things. The detection method was then used to measure neutrinos from the Sun, as mentioned, and didn't match the model of the Sun. More time and money later, Pontecorvo had some left over remainder in his maths, dealing with nuclear reactions and so neutrino oscillations were postulated. That is why neutrinos have mass. To fix the maths.

There's always one guy who asks on any physics video and I guess today it's my turn: Does this maybe explain dark matter? He doesn't say where these predicted extremely heavy neutrinos are exactly. But if they exist then that's so much more mass in the universe than we're currently aware of, right?

A bit off topic but when matter and antimatter destroy each other, what happens? Just release a ton of energy and that's it? Is there anything left?

Iirc specifically when an electron and positron annihilate you get a gamma ray photon out of it. Not sure about something like a proton and antiproton but I suspect the radiation is more complex than just light.

Okay, so why are heavier particles harder to detect, when the general trend of particle physics discoveries is toward smaller and smaller particles (protons before quarks, etc)? What kind of scale are we talking about? (I believe the last quarks to be discovered were also the most massive; is that for the same reason?)

To determine the absolute masses of neutrinos, catch them before they oscillate! To catch neutrinos, use what they love doing most to entice them: they love to socialize only via weak and gravitational interactions. This has led to the construction of Neutrino mass generation mechanism.

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. Gamma photons are produced when a tube unwinds producing electromagnetic waves.

While building his reactor, Enrico Fermi calculated a loss of mass after atomic decay. He knew it was a non-charged particle with a tiny mass. Like a very small neutron. So, in an Italian accent he said, "this must be a neutrino". Fermi died in 1954. So, I think it been a while since we have know about this.

It's not quite that simple! The full form of the mass energy equation is E^2=p^2c^2+m^2c^4 with the p term representing momentum. Even confirmed massless particles like photons can carry away momentum thus changing the mass without having any themaelves.

If we accept the seesaw model to be correct, and the planck mass as a hard upper limit for the mass of the right-handed neutrino, then conversely we could derive a lower limit to the mass of the left-handed neutrino

2'23" "this is not the point here" actually the reason why a change of neutrino flavor implies imperatively mass is super fun. A massless object must move at the speed of light and according to special relativity, such a particle is frozen in time. Or, if such a particle (like the photon) carried a clock and we looked at it, this clock would not move. But if time is not moving for this particle, it could not change its properties like flavor. This is why the observation of the neutrino oscillation (i.e. changes of flavor) implies that it doesn't move at the speed of light (even though very, very, very close to it) and accordingly, it must have a mass (even though very, very, very small).

Every particle has a purpose. I think neutrinos tell space to bend. Heavier particles like the tau and muon neutrino are created by maybe neutron stars, clusters or superclusters. The decay time of neutrinos, tau's and muon's would make the difference in the range of gravity.
