I stumbled upon this one right after watching your latest vid on neutrinos. Arvin, this has to be one of your top five. Wow! Because you touched upon questions that are close to my heart and made statements that resonated so very well with how I think about things. When you say something like 'but math is just a tool to describe reality' or 'we should not be too confident about quarks being the most fundamental', you so humbly put forward the limitations that we as humans have in describing the physical reality we inhabit. Let me assure you, this is NOT the way they are introducing these beautiful subjects in schools even now. The way things are presented is as if everything is known and we humans have mastered everything. Math is taught as if it is the end all and be all of the world. You made my evening.

True.

[@ac5]

I'm pleased that you brought up the fact that our understanding of physics is based on mathematical models, and not the actual processes themselves. Our desire to produce a grand unified theory is more to do with our need for simplification rather than a real description of the universe.

[@mcmoswane]

This might be a little misleading. Our understand of physics is also backed by empirical evidence. These are not just mathematical models that make sense, we also collect empirical evidence to back them up.

[@ac5]

@@mcmoswane I certainly agree with gathering empirical evidence to support mathematical models. And quantum theory has a lot of evidence to back it up. I just feel that although the models agree with everything thrown at them, they are just models after all. A single piece of evidence could require that the model needs tweaking, or at worst re-appraising. That's why physics remains so interesting.

[@hupekyser]

I never understood before how particles can form momentarily in vacuum space until now. So its actually the chance additive effect of waves combining in the field to produce a virtual particle at a given space-time point. (or words to that effect. Thankyou. My mind is blown with the ease you have of explaining complex ideas.

[@thedeemon]

No, if you look in QFT textbooks it's not like that at all. The description of virtual particles in the video is just something that was easy to draw and tell, not what QFT says about them.

[@ArvinAsh]

I consider it a matter of interpretation. I don't exclude other ways of considering it. But it comes from the fact that a quantum field is never still, and since it is quantum its properties are not well defined. So sometimes you have extra energy somewhere in the field, and that is what causes the virtual particles. You can imagine this in different ways than additive waves. But it comes from a surplus energy at some point from the field and its unsteady vacuum state.

[@DrDeuteron]

the extra energy is "old fashion perturbation theory", which Feynman ended. In the path integral approach: an initial state goes to a final state as a sum of all possible paths that conserve energy, momentum, etc: but energy can be negative or arbitrarily large in any sub-vibration, so that's a lot of paths, even if the initial and final states are just the empty vacuum. How that can't be "infinity" every time is a deep question addressed by the renormalization group equation, hopefully AA will make a video on that...the most difficult topic in rQFT.

[@xenphoton5833]

@@DrDeuteron not to imply that you are necessarily" wrong". But I think you &AA represent two sides of the same coin,though the interpretation you reference may be considered slightly more refined. Also, the term "conservation"can be misunderstood, and there's no such thing as" negative energy".

[@DrDeuteron]

@@xenphoton5833 the integral in the 1-loop photon diagram integrates d^4k over all (k0, k1, k2, k3)...and k0 = energy. Virtual particle live in momentum-space anyway (at least in Feynman diagrams) so it's really just labeling a negative frequency.

[@csabakoos1650]

The best and simplest explanation about how everything fits together I ever heard. Well done. It got me thinking, the issue is always time. It is time that does not fit. 1.It seems like time does not exist in the quantum realm. 2.A photon experiences no time until interaction. 3.Delayed-choice quantum eraser, backwards in time. 4.Entanglement, time is not an issue. 5.Gravitational time dilation, the presence of mass and energy warp spacetime, mostly time. 6.The rate at which time passes depends on your frame of reference. 7.The universe doesn't care about the speed of light. Then it does not care about time either. The speed of light is constant for all observers, probably because time has nothing to do with it. Time ceases to exist in a black hole, a singularity is just a different form of quantum state. The inexplicably rapid inflation of the universe. As long as the baby universe was in a quantum stat there was no time, except maybe if viewed from the outside or from an another dimension. Conclusion. Time is an emergent phenomenon. You can not measure something without isolating it and interacting with it. Interaction means emergence in time. Any thoughts?

Can you do a video on how the various fields manage to interact with each other and create bigger "unified" things. I.e if there are separate fields for all the particles, how do all of those separate excitations in different fields create an atom that stays together and behaves as 1 object, rather than independent excitations that would otherwise "float" away from each other and do their own thing?

[@DrDeuteron]

fermion fields are weird, because they have conserved quantities, so the particles can't just go away. They also "anti commute", meaning two particle can't be in the same quantum state: it makes them look like matter.

[@jaredf6205]

Also, are there virtual fields that aren’t really fields but are composites of other fields interacting that only seem like a field?

[@LuisAldamiz]

@@jaredf6205 - Wouldn't that be rather "virtual" particles in real fields? There are virtual photons, electrons, etc. but they belong to the electromagnetic field, electron field, etc. The difference is that gauge fields (bosonic fields) act as interactions between the fermionic ("material") fields: for example the electron and the proton (or two electrons, etc.) interact via the electromagnetic field (photon field, which is ironically not electromagnetically charged). As Dr. Gamma explains these fermions have "material" properties, so they can't be in the same place at the same time (unless they have opposite spin or similar, i.e. Pauli's exclusion principle) so the waves shown in the video better reflect the behavior of photons than anything else because they can add to each other in space and time, while electrons (for instance) can't unless in very specific ways (they do add up in time however because the double slit experiment applies to them but not in space).

Elementary particle, like electron, can be understood as a persistent closed flux of energy of electromagnetic oscillatons. Toroidal ring of homogeneous flux with radius r corresponding to reduced Compton wavelength {lambda/(2.pi) } = r. With mass m={h(trans)/c}.{1/r}, mass as a measure of real vacuum inertia to bending of energy flux (bending of Poynting vector). In a given referense frame. Bending {1/r} gives birth to mass. Or not, like for photon with no bending to ring, zero 1/r(infinity) Spherical symmetry of E, B stereosweep to spherical angle 4.pi gives impression of effective "stationary" field , atributed to elementary charge |e-|. In reality just mathematical construct, ratio of on ring centrifugal force in [N] and effective electric intensity E(effective) in [V.m^-1], i.e. N.m/V or J/V = [C]. |e-|={h(trans).c}/{r^2.Eo/(2.efactor)}. Eo/(2.efactor)= E(effectiv)=c.B(effect) r^2.Eo is invariant. So |e-| is invariant. |e-| = h(trans).pi/{pi.r^2.B(effect)}= h(trans).pi/Fio and Fio is magnetic flux quantum, known from superconductivity. Fio=h/(2.|e-|). Its inverse is Josephson constant, ratio of ring angular speed [Hz](energy flux with speed of light) and voltage [V] on a halfring E(effective).r.pi. Exactly like measured. Eo , Bo are estimated from mass density in the toroid. Toroid dimensions from electron magnetic momentum.

Absolutely love your episodes. You speak to so may of us “lay-humans” about something so incredibly complicated yet convey it in a way easy and beautifully imaginative to understand. That’s genius. When I’ve tried to explain the collapse of the wave function by observation Ive used the 1st person shooter video game analogy. Hear me out, lol. If you think about it, if you look down at yourself right now, all you see of yourself is your limbs and torso. No upper chest, no neck, face. Just like many 1st person video games. What you see in “your reality” is akin to what “your character” sees in his/her reality, (what’s on the screen) (You just see both “real” and virtual realities at once being the controller of this avatar, obviously ) I tell a person to visualize your video game character walking up to a house. The house is now on your screen. You see it as does your make believe avatar. Now, spin your character 180 degrees. Ask “where did the house go”?? It’s there… but it’s not. When the video game character is spun away from the house, the “house” goes back into 0’s and 1’s on a hard drive. Waiting to be pulled up again by the processor being told to do so by a “consciousness.” Thus, in your subjective reality, is what’s behind you “not really particles”? Just a wave of probabilities and until you observe this fief of waves does the particles not need to “exists” until consciousness collapses the wave function? If someone is facing you, the “waves of reality” collapse behind you but ONLY in “their” reality and what’s behind them collapses in YOUR reality?? Is this what’s going on?? Just a pondering

I love your analogy about quantizing a field and best of all I actually learned something that I wasn't expecting to learn. Up until watching this video virtual particle had never really made much sense besides just being told they existed - your ocean wave explanation just made everything click into place and suddenly not only does their existence make sense to me, but even the reason why a vacuum can create them! Thanks again!

[@schmetterling4477]

Anybody who mentions ocean waves in connection with virtual particles to a grade eight kid should be punished. That is absolute not what virtual particles are. They are mathematical terms in a particular type of perturbation theoretical expansion. There are neither real nor virtual particles in nature. Please do not lead the kids astray here. If a student asks you what a quantum is tell them the truth: a quantum is a small amount of energy. A virtual quantum is a small change in the energy levels of quantum systems.

Killer video. I've seen a lot of videos on this topic but you bring the healthiest level of scepticism I've seen. I kept thinking about the fact these "particles" are either purely math or energy detections. The idea of fields of energy perturbations definitely makes sense when compared to our maths and theories but i wonder sometimes how much of this is just us fitting our theories to our observations. Had we somehow made these observations without an existing theory i wonder how different our resulting theories may have been. It's also conceptually weird to think of all particles arising from fluctuations in a field, yet these fluctuations remain constant for years throughout space and time. Like I can fly across the world and spend 5 years abroad, come back and have plenty of the same atoms as before. Conceptually to think of the persistence required of these seemingly fickle fields/particles to persist over change in space and time is really weird and just seemingly improbable.

Great presentation - thank you Arvin! In my humble opinion, quantum field theory is currently the best approach to understanding of reality around us, but maybe it's all taking place in one multi-dimensional quantum field, not multiple fields. Those extra dimensions that we can't observe on our scale, are responsible for behaviors that appear weird to us in our observable three dimensions. In that multi-dimensional field, energy signatures we interpret as various particles propagate simultaneously, a little bit like radio waves of different frequencies propagate through space. Looking at the big picture, the universe is one big quantum field with small scale phenomena building the large scale image. I think the large scale landscape of the quantum field is responsible for behavior of the universe, not some "dark matter" or "dark energy" constructs we've invented. Quantum field does not have to be flat :-)

What an amazing video, sadly it ended ☹ waiting for more great videos. I want to ask, if the field shown here as waves are more 1D+height than actual 2D+height representation? Feels like they should have some boundings than hanving an infinite length in one direction, like at 6:33

Well done Arvin.... Love your Channel 👏

Love from India 😎😎

This is marvelous. Literally magical.

"This is all math" it applies essentialy also to non-quantum physics :-) Great video, thank you!

[@shohabunnisa4150]

Thank u arvin glad to know all the chapters......Awesome teaching superb👏🏻👏🏻

[@duprie37]

So we are really all just interconnected vibrating waves propagating on an infinite sea of quantum fields. My cosmic hippie friend Dave would just love this lol!

[@88_TROUBLE_88]

Yes, in a very rudimentary manner of speaking..

[@mondopinion3777]

In your ocean surface metaphor, the atmosphere lying against the water's surface is mirroring perfectly whatever waves are happening. Invisibly. This is profound.

Did gravitational have both nature (particle and wave) ... I think everything have both nature

[@narendrakarkee3543]

Yah I also have same question

[@ikrishna06]

@@narendrakarkee3543 I recently studied that gravitons are part of subatomic particle with zero mass...

[@bookman9897]

@@ikrishna06 existence of gravitons are not proved since we don't have proof that gravitation is a force but just result of curved space time

[@ArvinAsh]

Good question. Many physicists think the answer will ultimately be shown to be yes, but so far there is no evidence that it is such. We don't have a quantum description of gravity.

The animation of constructively interfering waves in the quantum field ocean creating virtual particles that last for a very few seconds was a masterpiece for me... 💎💎💎

[@michaelrenouf9173]

Absolutely brilliant analogy representing vacuum energy as the minimum 1 meter wave. Absolutely stellar job explaining the relationship with waves and particles

[@SukantaMohapatra-w9b]

I am fresher in the domain of Physics. It still interests me a lot to know the behaviour of particles in sub-atomic states. Beautifully explained. Thanks Sir

[@pallabimitra7584]

This is the BEST video till date. I understood everything. Thank you Arvin Ash.😀

[@vadymkvasha4556]

wow, at last I've got the idea of these virtual particles, how they appear and disappear. Really good explanation, thank you!

[@AndyCutright]

"These answers are deeply unsatisfying." YES THEY ARE! Finally, it sounds like my complete puzzlement about what exactly folks mean when they talk about these fundamental elements is addressed. They are in fact just labels we attach to things we don't understand. What is a particle? It's something we can measure! It's math! It's .. I am so happy to hear you say that ten different physicists are likely to give ten different answers. I thought I was going nuts. Also know I understand the slit experiment as actually a measurement that forces the location of a particle (whatever that is) to be resolved. I think the idea of the wave function as not at all a wave, and more that it's a probability distribution is clear in my head. All these representations of the wave function as an actual wave completely misrepresent this idea to most lay folks. It's crazy how powerful visual imagery is and how confused this has made so many folks.

[@Eztoez]

The best explanation of fields and particles. Beautifully visualized.

[@Byynx]

Best guy talking about science !!!!

[@esteedle]

Incredible video. Youve made the most understandable explainer of quantum field theory that exists. Pardon me while i share this video with everyone in my contacts list lol

[@jmanj3917]

Being familiar with this subject matter already, I still found this video to be enlightening. Well done, Dr. Ash!

[@richardvernon7019]

best explanation I've seen,...the visuals really help me understand despite having the comparative brain of a golden retriever, well done!

[@andycopeland7051]

This was interesting man. Thanks for the video

[@bol-loki]

Amazes me how sanatana Dharma also give this example of ocean as field and waves in it as particles!! Mind bending stuff!!

[@Livinginthepresentmoment07]

Best explanation I have ever seen! Thank you.

[@treyd3433]

This is the coolest channel on youtube!

[@hgracern]

Thank you dear Arvin. You amazing and your voice is very easy on the ears. ❤

[@heiyiplee2800]

Best visual so far! More like this please😊

[@LA_Viking]

One of the more lucid explanations I have seen. Well done.

[@georgefratila6773]

Great explanation ! Best approach to the true nature of reality !!!

[@jw4659]

Yes - great explanation! It's important to know that a "vacuum" is not really empty.

[@robertschlesinger1342]

Excellent video, as always. Very interesting, informative and worthwhile video.
