Ok, neutrino physicist here. Brilliant episode, as always, but with a small caveat. Neutrinos DO NOT lose energy going through the Earth's core. Something tells me you guys know this but the misleading information was born from didactics. What you probably meant is that the MSW effect suppresses tau-neutrinos at these energies and that is why they are unlikely. They would be observed with the same energies but as electrons- or muon-neutrinos (most probably the latter). So, no energy is lost, but the observation of tau-neutrinos at an specific energy value is unlikely, and yet, it seems to be the case. That's the puzzle.

@@felipecamposribeiro4852 Wikipedia will tell you, better than I can, the name of the three brilliant physicists which MSW stands for, but I'll do my best to explain: as it turns out, the three kinds of neutrinos are just labels that we apply to them when we observe their accompanying lepton, the electron, the muon, or the tau. This label is not a constant. It actually changes during the neutrino flight. In a vacuum, this change is periodic and therefore it is called neutrino oscillation. In the presence of matter, it is all different. Regular oscillations can be enhanced or suppressed, depending on the relation between the medium's density and the neutrino's original label and energy. More than that, any abrupt changes in density triggers another kind of label conversion which is not periodic. This is called non-adiabatic neutrino conversion, also known as the MSW effect. In summary, given the conditions in the Earth's core and mantle and the neutrino's label and energy, it is unlikely that the tau type is observed, and yet it is. But the energy is the same, no matter what. I hope this helps a little bit.

I looked into the Ice Cube archive, and determined that Today was a good day.

If we're running out of space to build large particle accelerators that function by conventional electromagnetic acceleration, why isn't more effort being put into figuring out wakefield accelerators? From what I've read, they can have far superior energy gradients, and accelerate particles with much less distance traveled. I understand that there's difficulties creating the plasma wake to begin with, but even those methods don't take up as much space as the LHC, especially when considering laser pumped wakefield accelerators, as opposed to particle beam pumped ones. As a side note, if we could find an efficient way to scale up wakefield accelerators, do you think it'd be possible to make a large array of wakefield accelerators pumped by solar pumped lasers, or by the sun directly, in solar orbit, to make an antimatter factory? It'd still consume plenty of energy to make antimatter, but if you could do it with thousands of small accelerators, it'd become much cheaper to produce than currently when using the LHC, and maybe open up new horizons in space travel. The main cost in antimatter production is the particle accelerator used, and if we could have thousands of small, relatively cheap wakefield accelerators, maybe antimatter powered space travel could become a reality?

​@The Truth of the Matter Right, but a very highly developed and sufficiently powerful Wakefield accelerator could do things for us that an orbital or even celestial accelerator would take decades to implement. Sure we cant know for sure that a Wakefield would be cost effective but we do know that it would be faster to build since we don't have to first construct a buildup of artifice in orbit for megastructures like that. IMO its worth a look as we could do a lot with a deeper understanding of the Standard Model and there's nothing inherently unscalable about an accelerator of the type.

@alobko1

5 жыл бұрын

Well, thousands of smaller Wakefields would probably be cheaper because they're much smaller and simpler each, however the main reason antimatter production isn't practical is because a) the cost of the particle accelerator is so high b) because we can't produce large amounts, since the throughout of each accelerator for specifically antimatter production doesn't change with energy much. As long as the accelerator has enough energy per particle for pair production, more doesn't help that much. Our current particle accelerators are huge, but that doesn't offer any advantage. It's like a computer CPU: some applications benefit from single core performance being better (science experiments), but others (like producing antimatter in mass) benefit more from parallelism. Having thousand of cheap, small Wakefields that can each create basically as much antimatter per second as CERN at a lower energy, would be better than having a single really big accelerator. The really big one would be great for science and terrible for industrial manufacture of antimatter. A hundred thousand cheap Wakefields with way less maximum energy but still enough for pair production would produce much more antimatter. My point was not to perform scientific research but to use the sun to create a energy dense fuel for space travel at scale. Wakefields are objectively better for this if we can use them this way because they can achieve the needed energy per particle within a few centimeters instead of dozens of meters. Much better.

At least that's one nerdy interpretation. However, it is not a generalized "double negative". That's because "weakness" is ambiguous, it can mean "weak coupling" in this context, and so "miniscule coupling" is a correct meaning.

Mad respect to those scientists. coming up with the theory AND math is so far beyond my reach. insane how smart some ppl are.

I'm terrible with names so I can't say who was doing this work, but there was some work being done to redefine quantum mechanics or at least the fundamental forces in terms of Octonion, rotations in an 8-dimensional space. This didn't change the 3+1 dimensions of actual space. The work was not complete to fully translate all of physics to this model, but the model itself does have some interesting properties that may imply why our universe is the way it is. For example, Quaternions, are a 4-dimensional structure used in computer graphics to eliminate the problem of gimble lock in 3-D space. The vector part of a Quaternion is 3-dimensional and a complex part that is 1-dimensional. In computer graphics this can describe an axis of rotation in 3-d space for the vector part and a scalar rotation for the complex part. Quaternions are non-communicative so i x j j x i. I recall, but I'm not finding the sources to back this up, that Octonions have a vector part that is 4-dimensional. Tranformations in Octonion space seem to naturally match quantum spin. Octonions are non-associative, so a (b x c) (a x b) c. And now the part that borders on woo. The non-associative nature of the Octonion may describe why time only flows in one direction. The next higher dimension of rotation object would lose the property of identity and therefore could not exist (I think I made that up but it sounds cool). Therefore, we necessarily live in a universe of 3-dimensions + 1 of time that flows in one direction only because of math! I would love to see a video about this that corrects my misconceptions on this.

I wouldn't know specifically, but back in college, and in grad school, I'd browse the journals for stuff like that. Unconventional QM, spinors and quaternions, fundamentals of space time and matter. Foundations of Physics was one of my favorites. David Finkelstein wrote some interesting stuff. Quaternions were definitely thought about. Octonions, I've seen papers, but that was long ago. If anyone is doing fresh work on that today, or recently, cool!

You left out that, because of frame-dragging, that neutrinos, as they travel through space, change flavors between the three types as a function of the distance they travel. Therefor, a muon neutrino can change into a Tau right at the detector (becoming more massive... requiring more reletavistic frame dragging to change to the lightest, the electron neutrino). The Tau (which used to be the muon flavor) could then interact at the detector. I'm amazed that you didn't explain to people that neutrinos change their flavor, even using words that leave people to believe that the neutrino types stay the same as they travel through space.

For quite complex reasons, the Anita signal can’t be explained by neutrino flavour changing. Currently there is no standard model or nuetrino oscillation explanation for these two events. I imagine that is why they didn’t discuss it, though I believe they have discussed oscillations in previous videos.

Isn't amazing that all these physicists who study neutrinos for a living have never heard of neutrino oscillations? Or could it be that any popular account of physics is going to leave out lots of details? And as far as I know frame dragging has nothing at all to do with neutrino oscillations.

Fantastic episode as always!

We have a deep neutrino lab where I live (and I’m a scientist) so this video really interested me. Thanks so much. I’ll have to see what our neutrino lab has published lately.

Actually science is losing crediblity drastically. Science should keep theories to themselves until they have been totally proven. One theory falls, another one rises. Over and over and over and over again. Why should anyone give a new theory a second thought? Just wait a few years or decades and it will be taken out by another new theory. How can anyone believe science. You are beginning to look like delusional lunatics.

@@Bryan-Hensley So... you basically have no idea what science and scientific method is... "String Theory" is a misnomer. It is an elegant hypothesis. Not actually a theory. Scientific terms have slightly different meanings than the same word in common use. A Fact is a sufficiently justified true belief. It is a statement about a phenomenon which is supported by evidence of sufficient quality and quantity to demonstrate a testable condition. Relating to Gravity the statement, "things fall down" is a factual statement. A Law is the quantification of a phenomenon. Things fall at a rate of 32 feet per second, per second. A Law increases the utility of a Fact by modeling it mathematically. A Theory, models the underlying mechanism. General Relativity is gravitational theory. Science is the only epistemology that produces useful information. Engineering is the practical application of science. You might want to get a basic science education so that you can determine for yourself whether your objections are well informed.

It's understandable because people take these theories as fact and then it another theory or law of physics slams it. It shocked me to know so many people now believe in a flat Earth.

much _much_ *much* better episode than last week! thank you :-)

when the standard model is SUSSY😳

You said that muon-nutrino can travel through the earth without slowing down, so what if it changes its flovour into tau-nutrino Just before detection

Another great episode. Also helped connect a dot for me. Specifically, I knew that Super-K, Ice Cube etc. map Cerenkov radiation onto, respectively, their surface or 3D matrix to determine where in the detector the event takes place and, by the light cone formed, the vector from where it came. What I wasn't getting was *how* the neutrino caused that. It decayed into a more massive (but lower energy) particle, which smashes into the surroundings at (locally) superluminal velocities and that creates the measurable light! Nice!!! Gotta love neutrinos!

Thanks Matt, another fascinating episode. Best channel ever!

It's defined by the relative stregths of the interactions between fundamental particles. For the gauge interactions (electro magnetism, weak and strong force) this can be uniquely defined because there is a fundamental unit charge. For gravity this is not the case. Usually the gravitational attraction between two electrons is used. One could equally well use the muon or any other fundamental particle. I don't know if it makes sense to compare the strength of gravity in the same way we compare the gauge interactions. To say that QCD is ten times stronger than QED is a precise mathematical statement. This is not the case for gravity.

Plot twist: it's the penguins using mobile phones.

If super symmetric particles require electroweak level energies to exist. Would that mean that right at the start of the universe, everything would be super symmetric? Does that mean the W3 and B Bosons are actually super symmetric and if so what are their normal partners? Also, could this be a candidate for inflation? When the early universe cooled below the electroweak energies all the super symmetric particles would decay into loads of regular particles which would presumably cause a massive and rapid expansion???

LOL yep Relativity vs Quantum Mechanics and so far gravity keeps coming up as a measurement of space time curvature and thus a effect not a force and thus being weak compared to the other forces is not a problem because it's not a force. Unfortunately Relativity has it's own holes, including black ones ;), so much more to learn there is.
