Deep dive into the known forces

- Popular science explanations of the standard model usually describe four forces (strong nuclear, electromagnetism, weak nuclear, and gravity). They also claim that some of the forces are stronger than others. What they don’t tell you is that all of those claims are only valid for distances comparable to the radius of a proton. For different size scales, the order of the strength of the forces can be wildly different.
In this video, Dr. Don does a much deeper dive into the topic. Prepare to be amazed.
Is the weak nuclear force really a force?:

More deep dives please. UA-cam is saturated with surface level treatments of science, so these are gold!
i would actually argue that the sheer amount of surface-level scientific content is actively very harmful to science literacy. it’s the IFLS-ification of science content.
@@slipperynickels It is indeed. Kurzgezacht, my nemesis XD
@@nikkan3810They are actually better than everything else out there.
@@foolishball9155 not by a lot. Making tons of claims that just have no experimental basis as if it's totally true and real. Too much confidence in things that we don't even have tools to comprehend, not to mention research.
@@foolishball9155
Kurzgesagt is one of the most surface-level, IMO. ScienceClic and Science Asylum are better for physics. You've got PBS Eons for paleontology. Myron Cook for geology. Professor Dave Explains is better for just about anything.
UA-cam is full of videos which are ankle-deep into particle physics, but the ones which go into intricate details and describe smaller topics in detail are rare. I would opt for having these kind of videos every once in a while, they are greatly appreciated!
As a theoretical physicist I've always been fascinated with cutting-edge particle physics because it's difficult to explain in simple terms without adding something irrelevant.
I'd say this videw was at least knee deep. Maybe even waist deep.
PBS space time does it well too
this is ankle deep. There's no math
@@sakesaurus1706 There are graphs of field intensity versus distance, arguably a math.
Scientist: Yo, gravity. You the weakest force!
Gravity: Come say that to my event horizon.
Scientist: Make me, I'm over here, and you're allll the way over there!
Einstein: Gravity is not a force.
When a force cannot withstand a non-force
that's a hoax. Gravity isn't actually a force. That's the plot twist. And the weak force is probably a pilot wave interaction rather than a massless temporary particle.
@@ZennExile No forces are actually forces. By QFT, they are all exited vibration of respective field. Taken this way, Gravity is just the large scale bending of its field, the space-time itself. Large-scale bending and short-distance vibrations seems to be fundamentally the same object.
This is a really nice balance of, "whooboy, it's actually a lot more complicated than you've realized" and "let's explain what's going in a simple, approachable way." Solid programming, would love to see more like it.
More deep-dives please. I never even realized that the top quark doesn't live long enough to feel the strong force.
Agreed, and I don't even know what that means: the strong force operates at a speed slower than the rate of causality? Is there a strong force equivalent of a sonic boom or of cherenkov radiation?
@@ChristopherCurtisit takes non-neglibble time for the strong force to take hold and bind quarks, and the top quark decays before that happens.
Think of it like the egg yolk disappearing before you get a chance to fully scramble your eggs in a bowl.
Thanks, but a disappearing egg yolk doesn't help. Gravity and EM move at the speed of light. How fast does the strong force go? And how far does it go to get there? Where is it coming from to get to this apparently-free top quark?@@glowerworm
@@ChristopherCurtis It's not slower than the rate of causality. The strong force simply isn't strong until a certain amount of time has passed because the particle needs to travel a certain distance before the force actually becomes strong. The weak force deals with that particle before it can get that far.
@@glowerworm not so bad of an analogy
The demand for more deep dives clearly restores our faith in humanity and physics. The deeper the better.
Deeper dives! You guys are one of the few channels with talent qualified to explain these concepts in more detail. Almost any science journalism channel can cover the broad concepts, and I feel it would be a waste of your expertise to rehash it.
In particular this video was excellent in clarifying my understanding of forces, and I've watched countless videos on the subject (as well as read several texts on it). For example, I had no idea that to escape the strong force, particles actually change into others which aren't affected by its influence. That is a concept I've not encountered before, and I appreciate it!
The changing into other particles behavior is at the heart of the LHC collision experiments. They smash protons together, and when Quarks get ripped apart from each other the energy is converted into a "zoo" of new particles which hit the detectors.
That's how I understand it, at least, as a layman.
@@onnastick Physicist here, your explanation is correct. It's simplified, but that goes without saying for this topic
When I saw "deep dive" in the title, I was expecting an hour long video! Shocked and confused the "deep dive" was only 10 minutes! Give us deeper dives!
More deep dives, please. Your delivery makes it so I can follow further down the rabbit hole than I otherwise could.
The shallow videos are a great introduction, but the deep dive ones are much more thought provoking. If possible, keep producing both, as both are valuable to different audiences.
Bump. #FeedTheAlgorithm
This.
Deep dives! It helps to satisfy the 'but why' questions we have been asking from childhood. Also it's great to understand the limits of what we know, why we have reached those limits, and what's next.
Couldn't agree with this more! "But why?" is the question I always want answered when I'm looking for educational content; why are things the way they are?
I don't know anywhere else on UA-cam where I can hear advanced level physics topics explained in such an easy to understand style.
It's what keeps me coming back to this channel.
There are plenty of other channels that offer surface level overviews.
Finally a video where there's no BS about "universe borrowing energy for a shortest period of time" but the (slightly) more accurate description of the force carrier having a small enough mass. Kudos!
What’s wrong with the idea of borrowing/returning energy? I would like to know if/why this is a mistake, because if it is, I’ve been making it.
Yes but you only probe a tiny bit more into this strange world. If you want to do it properly you need a mathematical treatment of the subject.
@@LeTtRrZbecause it's obviously a neat accounting tool and shouldn't be mistaken for reality.
@@Zamicol So, how should I think about the concept of energy uncertainty? How would you describe the idea of intrinsic charm of protons if not borrowing or returning mass?
@@Zamicolif it has predictive power it's valid physics, all of quantum physics is a series of elaborate accounting tools.
Absolutely more deep dives, please. How about a deep(er) drive into asymptotic freedom, which you briefly touch on here. Good stuff!
Yes, please Dr. Lincoln, a deeper dive into the weak and strong forces would be great! Keep up the great work!
4:50 One should mention that for _macroscopic_ objects, the negative and positive charges are usually almost exactly balanced, leaving only a _very_ small net charge in total. Hence for macroscopic objects, the ratio of charge to mass is ___much___ smaller than for electrons or protons, and hence the force of gravity is usually more important than the electrostatic force. (That's the point which all proponents of the "electric universe" conveniently ignore.)
> Electric Universe (EU) is an umbrella term that covers various pseudo-scientific cosmological ideas built around the claim that the formation and existence of various features of the Universe can be better explained by electricity and magnetism than by gravity alone. As a rule, EU is usually touted as an aether-based theory with numerous references to tall tales from mythology. However, the exact details and claims are ambiguous, lack mathematical formalism, and often vary from one delusional crank to the next.
why are you bringing this into the discussion out of nowhere?
yeah, but that's exactly *because* the electromagnetic force is so strong
you don't really see big charge differences in nature because that would require a lot of energy, whereas pulling two masses apart is much easier
your argument is like saying that the law prohibiting speeding is more important than the law prohibiting murder because a lot of people get speeding tickets but only a small number go to jail for committing murder
@@Mmmm1ch43l The only reason there _can_ be charge cancellation is that the universe 'happens to' have a very close to equal (if not actually truly equal) amount of positive and negative charge.
Deep dives please! Deeper and crazy deep helps me to know what I need to study next.
Love deep dives like this. As you allude to, UA-cam is awash with general primers on physics. Deep dives give us something rarer (though not as relatively rare as weak force interactions).
More deep dives! Thank you!
More deep dives. Love this host. Great explanations. Good energy.
I love the deep dive! More of these, please!!
Your intuitive exploration of uncharted territory provides a fresh and exciting perspective on quantum physics. Bring it! 💥
Great video, and YES PLEASE to more deep dives - there are already plenty of other videos without this level of depth. Thank you for doing these - the channel is terrific.
More deep dives, please! These videos are presented very well.
Yes, more deep dives are very welcome!!! Thank you for your great work.
Deep dive is fantastic, please do more! Love actually gettiing to *LOOK* at a topic instead of just glossing over it.
More deep dives - loved the explanation for the weak force
Yes Jedi Don, please do so, more deep observations! Many thanks!
This is one of my the most favorite channels! Please, more deep dives!
Appreciate the deep dives, and it's helpful to list the more basic videos on the same topic, for background information.
Excellent video. Deep dives at this level of detail are just what I need. Thanks and keep 'em coming.
Thank you for the vid! That was as clear as it can get. Would very much appreciate more of that level.
Love the deep dives. Keep them coming please. Thanks!
Loving the deep dives! This finally answers a handful of questions I had about the fundamental forces.
Keep the deep dives coming! Your UA-cam platform is unique. You cover a given topic first at higher level then more deeply in subsequent episodes. That maximizes your audience reach and allows users to customize their 'curriculum'. Really enjoy your books and Teaching Company DVDs.
More deep dives, please. You provide so much insight.
This format was great!
More please 🙂
Thanks for this brilliant video! I’d love to see more deep dives!
yes please, love the deeper dives. You're a talented communicator Don, very enjoyable.
thank you for the deep dive, the level of detail was just enough for me to understand easily with some thought put into it
Yes, thoroughly enjoyed this. I think deep dives into narrow topics are a good idea. You've done, and there are plenty out there, broader videos and there's only so many of them worth making
I really think many more of these deep dive videos are great and needed. Truthfully I would do a mix of videos that give a general overview and then a follow up deep dive video on the subject in question. Just my thoughts. Great job as always!
I love your dives into the "actual" causes everyday phenomenon (light bending, light slowing down, magnetism, etc.)!
More deep dives please! Thank you this video was great
I enjoyed the level of detail in this one, I like deeper dives for sure!
Details are fun and you do a great job of explaining them
I love this video style! Getting into nuance in any capacity makes these types of videos more interesting
Dive deeper - that’s why I follow this great channel - keep up the good work 😊
Easyly one of the best videos you ever made! Thank you very much!!!
More deep dive! thanks for sharing!
Wonderful as always, Dr. Lincoln!
Deep dives are great! It’s not often I find like a 2 hour long lecture on some scientific topic but it’s always a pleasure to watch them
I don't hold any qualifications in QM or any in maths and physics, but I find most UA-cam videos to be too basic; a little more depth is excellent! Your videos are at the perfect level for me, simple enough to (usually) grasp but complex enough to make me think. Thank you!
That was a great video which enlightened this topic. More deep dives please!
Great format, and subject matter.
I would love to see more content, in a similar format.
This answered questions that I've had for quite a while. Thanks - deep dives get my vote!
Don presents the absolute best videos on physics. More deep dives to stretch my mind even further, please! So far beyond what I can understand but I typically get a nugget from each. Not unlike my reading and re-reading A Brief History of Time probably 50 or 60 times in the last 15 years. I gain more understanding with each reading as time goes on.
More deep dive for sure. I've heard the same videos about QM a dozen of times. It is this type of content that gets me curious to do my own research on the topic
Definitely a deeper dive. That was awesome!
Just do it all. Initial broad strokes video and then circle around to the deep dive.
Love the vids!
Deep dives, please. Thanks for your great work.
deep dives are greatly appreciated, thanks!
Loved this one, more deep dives please!
Loved this deep dive. Please make more
I agree, more deep dives. Understanding what’s going on at a deeper level is what differentiates this channel from the majority of the others.
Deep dive is awesome! Please do it more 🎉
Loved the video, would love to see a longer form with more info and comparisons.
Please please do like a series of videos on this rabbit hole! You are one of the more knowledgeable persons in this topic on youtube, and basically everyone else only touches surface level stuff. I would adore if you delved in the rabbit hole mentioned at the end. This video was kinda mind blowing and now I wanna learn more about the four forces
The deep dive broadens understanding. More, please!
Brilliant. Thank you. More deep dives please
We love you Dr Don ❤, your expert explanations and style! Because phisic's everything...
Love the deep dives, sir.
More deep dives please!! They are not that hard when you explain them so well 👍
This video was incredibly interesting. I would definitely love to watch more deep dive videos.
Because, physics is everything
Thanks for the clarifications!
Please! Please! Please! More and more of these in-depht videos! Greeeeeeatly appreviated.
I vote for more deep dives! This was a helpful level of detail
Such a good explanation. I studied all of the forces individually but had never put them together in this way
Please more dive deep! We really are capable of handle them, you're a fantastic teacher! 😊
Both are good. Mix deep and shallow dives man! You are great doing any! Thanks
Great stuff, Dr. Don! ❤❤
Great work! More deep dives please!
Deep dives are great, especially when you can link back to broader concept videos upon which one can construct a foundation for understanding. You’ve established quite a library for such development. Go for it!
I really liked this take on the relative strength of forces - I had never heard this before! Would love to hear more explanations like this. Thanks!
Deep dives are great; I'd enjoy seeing even deeper ones.
Loved this. Deep dives are great!
These deep dives are really cool. Definitely more of them. I would love a more in depth discussion on the electroweak force, for example
More deep dives please! This was an awesome video!
This was awesome. Super informative and interesting
Amazing explanation. We want more deep dives please!
More please! I feel like I actually learned something for the first time in a long time. Or, at least seriously challenged my rudimentary understanding. I didn’t understand weak force before, still don’t, but now it feels like there is something more I can learn.
I love those deep dive's. It tells me more than i can expect from the common videos.
This may be my favorite video! I would love more of the in depth videos. UA-cam already has a lot of surface level videos. Deep dive as deep as possible! Thanks!
This is a good video for me. As a passive physics enthusiast a lot of what I hear from videos are things I already know(or things that are wrong). This sort of video is right at my current level where it's understandable and informative.
Dr Don, I thought this was very interesting. I appreciate the 'deep dive'. More like this would be welcomed.
Ah, another channel i can watch at 3am about physics while understanding absolutely nothing.
Best way to fall asleep.
You will make a fine addition to my collection
More deep dives please. This video helped me resolve some lingering questions I had about relationships between electromagnetism and the weak & strong forces. It's exactly the kind of zone in between popular science and university research level science that there needs to be more of in order to help bridge the gap for the curious.
Deep dive you are the best in explaining these findings.
Very intelligent comparisons. Thank you!
The deep dive was great. thanks!
Really enjoyed this deep dive!
