One of THE best videos on particle physics I have ever seen.

I envy the new generations of students and hope they appreciate just how valuable these productions are. Thanks Alvin!

Arvin, this is amazing. Thank you for doing this video as I think a lot of people forget that we don't necessarily have to see something directly to know it's there. This is becoming so much more important as there is so much now in physics we can't directly see, but need to find a way to indeed conclude something is there. I hope the science community keeps going with ways to find things that we can't directly see and each of these discoveries is huge. We will always question things and that's good, but we have to learn to make sure we follow the science that's already been concluded. If something is 5 or 6 sigma we can't dismiss it and say it doesn't exist and do some totally different stuff. The only way we make progress is by following what we have found and building on that. As hard as it is. You can find a billion ways to not find something, but the hardest part is finding the one way to find something. This is where I don't agree with experimentalist that all tests are good as they say the result is progress regardless. But it is not now a days as science has become very difficult and very expensive. A.k.a.......... ITER

(Still acknowledging that you are in fact very informed and knowledgeable and a great teacher)

Great stuff! Yea we always need to remember that we aren't seeing reality directly but rather our interpretation of reality through the lens of our senses and our own mind. Could be that there are alien civilizations out there that have a while differently model, every bit as valid as our own, completely depending on how they are measuring and interpreting the results of their inquires. The mental map is not the territory, but rather only a representation of it with varying/unknown degrees of accuracy.

What literally blows your mind in the decay process: we can predict with what rate the substance decays and with a really huge precision. But absolutely in no way we can predict when decays one chosen particle. It can decay now or at the end of the universe! No way of predicting. And at the same time there is no such notion as "age" for a particle. Every particle of a chosen type is absolutely the same as any other particle of this type.

Informative and well done as always.

I was at CERN in 2017 in a masterclass setting and learned this first hand. Blew my mind, as the discovery of the Higgs is both mathematically sound while being 100% unsatisfying. I too had to quiet the "bullshit" bandit that kept making its presence known. Luckily my host is one of the greatest at ATLAS so I was ultimately able to take in the science.

Well, both eyes and LHC are kinda doing the "same" thing. Let me explain... When animals (including us) see an object, what's happening is that the quantum particles of light (i.e. photons) coming from the object hit the quantum particles that make up our eyes. The energy transfer from these collisions kicks off a chemical chain-reaction, starting from the retina, through the optic nerves, and to the brain. We experience this chemical process as sight i.e. we see the object from which the photons came. In other words, sight of an object is caused by the interaction/detection of photons coming from that object. The LHC discovered the Higgs-Boson by the interaction/detection of photons coming from Higgs-Boson. So, in a way, the LHC did see the Higgs-Boson.

@colder5465

7 ай бұрын

With "seeing" we have a big problem when we go to microsizes. In order to see we have to light the object. But light is also a particle - photon. In other words, we make the object interact with another particle and "see" the result of this interaction and not the initial object. Another big problem: the huge difference in sizes of visible light photons and, for instance, an electron. The electron is much much smaller. So in no way we can't see the electron.

This is the definition of profound..great video👍🏼

Excellent video as usual! I have been wondering about this ☺️

The more I learn about the Higgs "discovery" back in 2012 and how it dictates the mass of particles within it's field, the more I think it was a discovery of justification. It justified the huge cost of the LHC and then managed to justifiy further billions for upgrades.

That's super interesting - I love these detailed explanations. To put the numbers into perspective (like you did for the ratio from Higgs to electron), I suggest adding a human-relatable reference. For example, for the 10^-22 lifespan of a Higgs particle, the age of the universe is 10^17 in seconds, so the Higgs would experience 10^5 universe lifetimes (in seconds) compared to 1 human second - it degrades that fast, which is still mind-boggling 10^22 times more than the plank time. It would also be interesting to know the frequency of the emitted photons from the Higgs decay vs the frequency of the gamma rays from supernova or antimatter/matter collusion. It would also be interesting to understand the energy multiples between the various particle flavours (ie electrons) and how they are manifested in the quantum fields; or why we think specific fields interact with only other fields - and how.

@quitchiboo

7 ай бұрын

Frequency of one of those decay photons (about 1.5*10^25Hz) is higher than the most energetic gamma ray photon ever recorded (GRB 970508) which had roughly a frequency of 10^24 Hz. So you wouldn't expect to see a lot of those around. What you describe in your last sentence is a very hard problem in particle physics, namely how to explain the mass-ratios of the fundmental particles. Afaik, these masses are free parameters in the standard model, which means they cannot be derived from theory but must be measured.

Could also add, even if the created Higgs boson wasn't stationary, but was actually travelling at light speed, in 10^-22 sec it would only travel 10^-14m - ie, way less than a nanometer- and could never hope to reach a detector directly. Its existence NEEDS to be inferred from its decay products.

Gosh, the amazing facts of scientific study keep coming. Thanks Arvin Ash.

It was the first I heard the Higgs remains essentially stationary and never moves toward the detector with ~0 momentum. That was interesting. I had always heard the usual that near-instant decay was the process why Higgs wasn't detected directly, but the lack of momentum was indeed interesting to me.

The Higgs boson does have momentum, it is produced by particles moving very quickly. It doesn't move very far before it decays but it still has quite a large momentum.

This man gives the best and digestible explanation of theses complicated subjects, And I can say that with a gazzillion sigma of statistical significance.

Another great video! The number one confusing thing for people in my experience that I get asked the most when they watch videos like this is the heavy use of phrases like "10 times 3 to the power of negative 6". People that don't deal with numbers written like that, have no idea if that's a big number, a small number, and everything said after that is lost because they can't follow along anymore. Just a quick explanation of that, even though it might seem silly, would go a long way of helping even more people follow along in these videos.

I guess this is the best channel on youtube with simplest-but-not-simpler-than-necessary explanation of complex stuff...

"Wait a minute, this is all bullshit!" Made me laugh out loud! Wonder video, thank you!

The graphics and the explanation on this video was truly amazing. Thank you for the video. I have one question, is there a reason that particles exist at just specific amounts of energy ( like 125, and etc) and if we call these amounts of energy, particles, then the energy in-between these numbers should be particles as well even though they might not last long and are there infinite particle fields that we can only detect some of them because of the available particles (like photon) we are using to detect them? And how do they shoot particles like protons and make sure they will collide?

@quitchiboo

7 ай бұрын

The reason for those specific numbers is that those are the fundamental excitation energies of the underlying quantum fields. If you hit the electron field with 511 keV it will resonate and "spit out" an electron. If you give it more than that, the resulting electron will just be faster until you hit the field with 2 * 511keV, at which point it will "spit out" 2 electrons. One of the biggest problems in particlephysics is why the ratios between the masses of the fundamental particles are the way they are, which cannot be derived from theory but must be measured.

Imagine if gravity somehow worked like this: Big masses like sun and Earth would repel/stretch the Higgs Field.

The experiment could have been done without knowing the theory at all. Probably 99% of all science progresses by conducting experiments and observing new and unexpected results, rather than having theories and then building experiments to test the theories. Not every scientist is an Einstein, who came up with correct theories before any test existed. But even Einstein sometimes came up with theories after experiments, such as when he uncovered the photoelectric effect when he was expecting a completely different result.

@@surajvkothari I don't consider "quantum gravity" to be a theory, because there are no formulas for it, or data suggesting it... it's just two words: "quantum gravity." For something to be a theory it needs more than a title. The "multiverse theory" should also not be called a theory, because there's neither data supporting it nor a formula describing it. I suppose you could call "alien life" a theory because at least there are some unidentified aerial phenomena. It's still a weak theory, but there is a small amount of data pointing in its direction. Even if they didn't have the Higgs theory, they still would have noticed the spike and then probably would have come up with the theory. They didn't need the theory to observe the spike. But sure, they had to have the theory in advance to "know where the spike should be." The theory predicting the spike was great, and adds credibility to the theory, but they didn't need the theory to observe the data that now supports it.

Nice one. "Physics does not guarantee the truth, only the most reasonable explanation...". And when a more reasonable explanation is found, the truth follows suit.
