Guys...let me know what you think of the sound on this video. We tried some new sounds and sound engineering on here. I would appreciate your honest feedback. Love it, like it, don't like it, hate it? Your constructive criticism is helpful, so we can continue to improve on future videos. Thank you.
Sounds just was great and Cristal clearly for me. In this video, the music was more clearly than the other videos. Especially in the middle of the video, music actually touched me (I wanted to say it, even before you asked. I thought it's just for me. But you said that you try to improve the sounds).
Thoroughly enjoy watching your videos and really appreciate your clear/concise explanations. I feel it has the right amount of detail so as to not overwhelm the non physics major yet enough of it for someone who would be interested in learning about the very universe we're living in.
Hi Arvin, I strongly disliked the music on this video, it made the explanations much more difficult to understand as I was focussing on the music rather than your voice. Please remove the background music completely, I can't understand why you would think it adds anything to the video as it's very distracting. The content, script and animations of the video were excellent as always.
I have been struggling with my health since middle school, I am unable to go to college right now and I appreciate the time put into these videos so I can still learn despite my health issues. THANK YOU
Lmao, I typed in “Einstein gravitational theory” and found your video on it, was blown away and watched it multiple times and had utterly mind-blowing epiphanies at having it explained so clearly. By the end of the video you had me dying to know more about Quantum Gravity - but I suddenly remembered string theory, something I’d heard about years ago, and wanted to see if the two were connected. Typed in “quantum gravity string theory,” clicked the first result, heard your voice, clicked subscribe. Hell yeah man. This is gonna be awesome.
I follow a lot of channels talking about physics, most of them having millions of followers, yet your videos speak to me and everytime I watch one of them, I learn something new that sticks in my head and becomes My Reality. Thank you Arvin !
This guy should get a full documentary series on the tv. I watch all his videos. He has a gift for teaching and his smile is infectious. I specifically enjoy how the information presented is not biased nor opinionated. Great content great channel. Thank you.
This video is the most overarching and in-depth science video I've ever seen. I constantly had to rewind to make sure I absorbed everything. Magnificent job! ⚛︎
As a subscriber to numerous physics/physical science/cosmology/whatever channels, I find yours to be one of the most lucid, understandable, and succinct yet comprehensive channels on RubeTube.
Very clear and understandable! In a nutshell and without the math (though mathematical formulae show up, even the complete Lagrangian of the standard model!) the basics of the two theories, and their differences, are presented in a way that makes one understand the Nature of both. Quantum loop gravity even more than string theory. Thumbs up!
RUclips says this is the last video I'll ever see without removing ad block. I guess this is good bye. You've consistently done a great job explaining the meat of concepts without dancing around them or injecting inaccuracy that just confuses people like some other science communicators. Thank you for that.
Wow. I loved this! Arvin you should get a prize for popularizing science!! The most complicated theories presented in such an approachable way. Truly impressive, you’re my hero man🙏🏼👍🏻👏🏼
Thank you so much Arvin Ash, this is an amazing explanation video. You explain it in such a simple way and use pictures to help me visualise it. I tried PBS space time but they are too complex and they dont explain it simply enough but you do, thank you.
This is pure gold. Very logical and nicely presented content. That animation of bosons getting exchanged analogous to the people on the boats was awesome. A very nice perspective to understand attraction and repulsion, caused by exchange of bosons. Similarly for Loop Quantum Gravity the animation was excellent. These things create a perspective which is hard to get just by reading. With this, when the maths behind it is studied will help bolster the understanding for young people and enthusiasts. A great service to Science
The richness of details along with the amazing clarity with which you present this information to us in your videos is, I think, unparalleled on RUclips. Keep up the good work, Arvin!
Hello sir. I am 12 years old and I am learning quantum , thermodynamics ,electromagnetism,string theory and the best lesson is quantum gravity. And your video was really helpful and I enjoy it✅✔✅✔🚀.
You born astrophysicist.Not only ,you authored at age 12 calculus book and atrophysics book about quantum gravity and every thing related to physics! Wish you to reach your dream to be Astrophysicist
Same here. Even i am 15 yrs old and learning these concepts. If we could team up and work together, it will be more easier for us. Think about it and tell me ok😄.
Very cool explanation of loop quantum gravity, I've listened to a lot of videos on that topic, but this is the first time I heard it explained so straightforward and understandable! With that in mind, could you make a video on just LQG? Would love to hear more details about it from you
I'm a researcher (in particle physics) and I think your video is extremely well done. I'm not sure though how much a non-expert in physics would understand ;). One comment about the part of the video where you argue which one between QM and GR is incomplete. This part is a bit misleading, since GR is a theory while QM is a broader concept which comprehend several theories (classical QM, SM of particles,...). I understand that this is not easy to explain in 15 min, but I would simply say that both approaches are incomplete and they need to be unified. Keep doing your amazing videos! Best wishes, NG
This was an outstanding video. You explained why it's difficult to reconcile quantum theory with general relativity, and you explained loop quantum gravity and string theory, and how they attempt to solve the problem, and you did it all in a way that was easy to understand. Impressive.
because its a line not a plane. :P but penrose puts it you need the extra dimensions so the strings can intersect, overlap and curl up, if they were in 1 dimension or less than 4 or 5 i forget off the top of my head, they would not be able to so the extra dimensions the strings exist in allow it.
C-shaped strings joining together create o-shaped strings. Now you can move from 3d space into multiverse. Space-time is not flat, but like bubble wrap upon bubble wrap.
Each beer adds another dimension. You need 9 beer to vibrate like a one dimensional string in 9 dimensions. With a partner, you enter into the realm of closed strings. Beer. I need beer!
@@scottmiller4295 , thanks miles, obviously! I started on those beers too soon I think. I don’t know what I was thinking. Of course a line is one dimensional.
@Arvin Ash Probably one of the best videos in physics on youtube. I have no background in physics but your videos and the animation make complex theories so simple and easy to understand. Kudos on another great video. Can't wait for the next one. Btw can you make a video on the holographic principle and how it conservation of information on black hole, and if it is related in any way to the quantum gravity or string theory? Thanks
Thanks for your kind words. I made a video a while back on holographic principle. If you search on youtube for "holographic principle arvin ash" you will see it.
My teachers ruined physics for me as they didn't even understand but after 24 years now I have started to understand physics better and better from your videos. I wish I had a teacher like you. I will see if i can solve this problem
Y'all are fantastic at this. Glad I found this channel. Love your work, Arvin. I wish I could see a collaboration between you and Matt O'Dowd from PBS Spacetime, somehow. Perhaps a pass-off video where y'all split the video halfway, each discussing a phenomenon/problem from a different perspective. (Could even be filmed remotely.)
One of the best introductions to why our reality is mind blowing. Can't squeeze all that stuff into a short video but enough to touch on the main points. Relativity, quantum physics and the far out theories trying to reconcile them. I like the explanation of string theory.
Dear Arvin. Thank you for your amazing way of explaining so complex things in a understandable way. Maybe the background sound could be a little lower, but your visualization of complexity is phenomenal.
Sir,the sound effect in this viedeo is fasinating and have different dimentions.thanks for the lovely efforts ,thanks to the sound engineer also.it is fantatastic to hear nature ,secretes with your clear explanation along with the lovely misitical hevenly musical sound.
Strings as points in time could vibrate in extra dimensions bottom to top, quantum dimensions of planck time, and regular spatial dimensions as part of graviton particle when reach planck space
I think advanced research on black holes can provide us with some solid evidences of either of the two theories. The amount of gravitational fluctuations around primordial black holes is massive and these fluctuations can unfold major secrets. The gravitational fluctuations can be detected as disturbances in the speed of light which can unveil something about Loop Quantum Gravity. On the other hand the space around the singularity can provide us something interesting about string theory. Let's hope we unravel this mystery soon.
I have read but mostly watched so many videos about these theories and in general i understand them as a concert, yet struggle to keep up in some way. Never the less i keep watching 😁. Thank you for the educational video
Superbly well explained! All the right questions. I successfully derived the centripetal a = v^2/r from no more than the notions of Planck length & time from quantum loop theory and energy density that General Relativity's equation includes. Knowing next to nothing about any of these, I overly simplified.
I realized why I like your contents. The introduction is everything, it reminds me of scientific journal articles' abstract. Instead of reading it, listening is more interesting and easier to understand. Thankyou so much, Sir 🤓
At uni, I came up with the postulate that the expansion is not universal but happens in discreet areas. Like bubbles of space expanding. Thay would mean they collide and the colliding parts would have different relative speeds. If the relative speeds reach certain %ages of the speed of light, the place where the "collision" occurs will be subject to time dilation and space contraction. I.e. tiny, "permanent" areas of space will manifest. We interact with these as "particles". So, a particle is actually just a part of space that exists on a different level to the rest of space. This explains why things appear "quantised". If you look at deep-seated images, you can see galaxies form at the edges of voids of space. Just an idea. I was never good enough at the math to calculate spherical and vortex phenomena in actual equations.
As always, an excellent video, Arvin. It's time to start formulating a theory of gravitation, in which mattergy (Mg) displaces spacetime (ST). Here, Mg and ST are both seen as possessing mass and density---with Mg as possessing more and ST less. This allows Mg particles, forces, and fields to displace those of ST. Further, a force within ST, akin to the EM and strong forces, acts to pull any displaced ST components back together to close such displacements. Finally, the continuous pushing out of ST by Mg and pulling inward of ST by a sort-of integrity-field would be felt as "gravitation." Maybe you can do that.
Superb Video Arvin, Do you think this implies simulation because of such rule set kind of like how we define while programming, configuration of fundamental constants, plank's length, time as shortest for this universe!
I don't think so. Our universe simply has some mathematical rules that it abides by. Proof of simulation would have to come in some other form in my opinion.
The universe doesn't run on maths, maths is the decrypted form of the universe. Or perhaps we are just all a simulation indeed, in that case, hey infinitely dimensional alien, nice work and all, but could you remove the "existential dread of being at your 20's and still having accomplished nothing" feature?
Never disappointed by Arvin Ash! Presenting material in a way one can understand. You didn’t lose me once. And your passion always inspires me to imagine the possibilities while you’re talking. Never boring always educational. Thanks Arvin
I've watched all the great physicists try to explain why quantum theory n GR can't b combined , hours n hours n in just the first 5 minutes I now get it ! Professor Jim Al. is my favorite also but your right up there Arvin keep explaining n I'll keep watching ! Thanks
I feel like I need two more cups of coffee and a PhD to fully understand this video. And that’s considering that these are mere representations of much much much more complex mechanics.
@@ArvinAsh Would it be too late to suggest that the reason nine dimensions are needed in ST may be due to the three fundamental QM forces each having their own independent 3-space manifold to operate within, all intersecting at the quark?
It's close but there is a misapprehension i think. In my opinion electrons quarks etc. is not particles. We think they're particle because the device that measure the particles works with high energy beams and that beams concentrates energy thereupon the energy becomes particle.
arvin always makes these topics so clear and understandable for us plebes. and fun too. as soon as he says sonething and i have a question he covers it.
9:29 "Loop quantum gravity (LQG) predicts that the speed of light has a small dependence on energy." Wait... what? Whoa! Now THAT'S what's called a RISKY prediction!
It is not necessary to demean others while complimenting someone.Neil is someone who make science intresting for general people and only after someone takes intrest in science someone like arvish can help to understand the scientific concept in depth.
You give a really illuminating exposition of the attractive mechanism for photon exchange between unlike charges. For that alone I'm grateful, as I had understood the mathematical reasoning decades ago but never got a visual image of the process. But the explanation of the difference between loop-quantum and string theories is wonderful. I am a physicist of a much more mundane sort. Even though I use quantum theory daily, this field is one where I very much lack the tools. I'm planning slowly to teach myself, simply to delight in the elegance (and appreciate the gaps).
Who said? From what i gather he would be unlikely to use much social media at all. Too much time thinking bigger thoughts than 'wonder how people feel about lamb tonight ....' ;p
Isn't that last statement quite ironic. Great videos by the way, they are excellent mix of complex ideas with comprehensible explanations, but not overly simplified.
The legend teacher of the world if you were my science teacher I would kiss you not because of loving you for your explanations that make me curious about science and now I'm learning it more and more and more every day of my life and doing some experiments for better understanding.
Excellent research and video Arvin. Scientists are very close to linking gravity with quantum mechanics. Understanding the small (lower) extra dimensions of the quantum realm within the fabric of space will lead to discovering wormholes and the inside of black holes, how they function and to where they lead. 👍
Thanks, A.A. for a clear and informative video. It is just my opinion, the thing that is fundamental to our spacetime is the galactic plasma, which can be quantized. The music is good.
Thanks for making this video. It answers so many questions - why quantum physics and GR don’t talk to each other, what is quantum gravity, why we need to reconcile GR and quantum theory and many others. However I’m still not able to understand how space and time occur in LQG. I realize this is very complex, but after watching many many videos and reading many articles, I’m still not able to visualise it. Could you please do another more detailed video on this? I’m sure a lot of people would benefit from it. Thanks!
Very lucid explanation of some very mind boggling concepts. Wonder if we will ever work out the full story of our Universe and how it interacts with other possible Universes?
Fascinating that both mysticism from ancient yoga and modern mathematical physics have the same impulse toward unification. Yoga is a word that means "union", after all. Where does this drive to unification arise in our psychology? Science is often critcised as being reductionist, but this tendency reveals that the deeper drive behind analysis is synthesis of the results. This comes to mind because both of these approaches to experiential understanding are beset with intellectual difficulties. Mystics are no closer to a unified understanding of how duality can be subsumed in nondual awareness, than scientists are to unification theory. Is this because of a logical contradiction, or is it due to the nature of experience, of reality? The answers seem to be irrelevant to the fundamental human drive to unify the parts, in that both of these strangely motivated endeavors will continue even if some dogmatic ideology arises from experience which purports to prove that "unity is impossible" in the sense that it either does not exist or simply cannot be symbolically understood and expressed. Such as Godël's results on the incompleteness of arithmetical logic. If not even arithmetic can be freed from paradox, the physicists' program would seem to be inevitably downright illogical. Based on a faulty premise -- that a noncontradictory expression for a unified theory can be written or thought. In that case, the lack of a paradox-free explanation doesn't say anything about unification in actuality, but it speaks to our limitations as computational beings. The physics version of arithmetical propositional indeterminacy might read as something like "any mathematical expression powerful enough to describe everything in terms of fundamental forces is necessarily a generator of paradoxical statements that cannot be resolved within that same framework." ? But at least the wet neural network of a yogi is more philosophically (or perhaps just psychologically) amenable to holding paradoxical concepts even while practising their art. This is perhaps the source of interest in mysticism among quantum theorists, and its popularity among non-physicists. Onward! Haha

Further, a force within ST, akin to the EM and strong forces, acts to pull any displaced ST components back together to close such displacements. Finally, the continuous pushing out of ST by Mg and pulling inward of ST by a sort-of integrity-field would be felt as "gravitation."
Maybe you can do that.
Superb Video Arvin, Do you think this implies simulation because of such rule set kind of like how we define while programming, configuration of fundamental constants, plank's length, time as shortest for this universe!
I don't think so. Our universe simply has some mathematical rules that it abides by. Proof of simulation would have to come in some other form in my opinion.
The universe doesn't run on maths, maths is the decrypted form of the universe.
Or perhaps we are just all a simulation indeed, in that case, hey infinitely dimensional alien, nice work and all, but could you remove the "existential dread of being at your 20's and still having accomplished nothing" feature?
I see that string theory comes with a lot of strings attached
wow, where did you pull that joke from.

Never disappointed by Arvin Ash! Presenting material in a way one can understand. You didn’t lose me once. And your passion always inspires me to imagine the possibilities while you’re talking. Never boring always educational. Thanks Arvin
Awesome! Thank you!
I've watched all the great physicists try to explain why quantum theory n GR can't b combined , hours n hours n in just the first 5 minutes I now get it ! Professor Jim Al. is my favorite also but your right up there Arvin keep explaining n I'll keep watching ! Thanks
Thanks. Be sure to check this out as well on the subject of quantum gravity, where I get more into it: ruclips.net/video/S3Wtat5QNUA/видео.html
Will do
Very well explained ! All told, the video was excellent (sound was fine). Thankyou !
A more balanced approach to explain the theory of everything than other channels. No pet theory, just facts.
I feel like I need two more cups of coffee and a PhD to fully understand this video. And that’s considering that these are mere representations of much much much more complex mechanics.
When you think about it string theory is so messy compared to lqg.
But keep in mind, ST would also explain more things.
I agree seems very out there, but reality is weird
@@ArvinAsh Yes definately, when you come up with lots of extra dimensions to prove your theory there's lot more explaining to do ;)
@@ArvinAsh Would it be too late to suggest that the reason nine dimensions are needed in ST may be due to the three fundamental QM forces each having their own independent 3-space manifold to operate within, all intersecting at the quark?
@@markiv2942 The bigger problem is IMO no super symmetry partner particles have been found yet, which is very odd.
Çok güzel bir video olmuş. Teşekkürler. Bu kadar karmaşık bir konuyu bu kadar kısa sürede bu kadar sade ve net anlatabilmeniz çok güzel
It's close but there is a misapprehension i think. In my opinion electrons quarks etc. is not particles. We think they're particle because the device that measure the particles works with high energy beams and that beams concentrates energy thereupon the energy becomes particle.
The next Einstein will never come but the next ' Someone' will surely come.
This premier is such a great idea. Amazing channel, keep going 🤗
"Complexity is the result of Simplicity not wanting to be alone." - Wald Wassermann, Physicist
Excellent simple but deep discussion to the conflict between both theories. Thank you for your great efforts.
arvin always makes these topics so clear and understandable for us plebes. and fun too. as soon as he says sonething and i have a question he covers it.
9:29 "Loop quantum gravity (LQG) predicts that the speed of light has a small dependence on energy."
Wait... what? Whoa! Now THAT'S what's called a RISKY prediction!
Explain your statement.
Always the best, simple but rigorus.
Arvin Ash has had an exponentially greater success at increasing my scientific literacy than Neil DeGrase Tyson could even hope for.
It is not necessary to demean others while complimenting someone.Neil is someone who make science intresting for general people and only after someone takes intrest in science someone like arvish can help to understand the scientific concept in depth.
Yo that was kinda low key racist my guy

Amazing stuff ❤❤. I will watch all your videos soon
Great to see the channel grow and the audio is better I'd say.
Thank you! I finally understand how general relativity and quantum mevhanics do not work together. 🙏🏼🙏🏼🙏🏼
I will try my best to help humanity by making a theory of everything 🤞in future .
This has been the absolute best explanation so far
Thank you so much, im writing a paper on this topic and this video is actually so incredible! I really enjoyed watching it!
Glad it was helpful!
You give a really illuminating exposition of the attractive mechanism for photon exchange between unlike charges. For that alone I'm grateful, as I had understood the mathematical reasoning decades ago but never got a visual image of the process. But the explanation of the difference between loop-quantum and string theories is wonderful. I am a physicist of a much more mundane sort. Even though I use quantum theory daily, this field is one where I very much lack the tools. I'm planning slowly to teach myself, simply to delight in the elegance (and appreciate the gaps).
The next Einstein would be lost in scrolling his phone
Indeed!

Who said? From what i gather he would be unlikely to use much social media at all. Too much time thinking bigger thoughts than 'wonder how people feel about lamb tonight ....' ;p

Gravity is a consequence, not something that has objective existence.
yes
Gravity is - The difference between slower and faster time flow in the time space.

Isn't that last statement quite ironic. Great videos by the way, they are excellent mix of complex ideas with comprehensible explanations, but not overly simplified.
The legend teacher of the world if you were my science teacher I would kiss you not because of loving you for your explanations that make me curious about science and now I'm learning it more and more and more every day of my life and doing some experiments for better understanding.
Extraordinary content. Thanks a lot Arvin Ash👍
Long live LQG✌
Excellent research and video Arvin. Scientists are very close to linking gravity with quantum mechanics.
Understanding the small (lower) extra dimensions of the quantum realm within the fabric of space will lead to discovering wormholes and the inside of black holes, how they function and to where they lead. 👍
This was easily the most fascinating and well explained video I've ever seen. Incredible. Smashed that subscribe button with the force of the sun
Thanks, A.A. for a clear and informative video. It is just my opinion, the thing that is fundamental to our spacetime is the galactic plasma, which can be quantized.
The music is good.
Thanks for making this video. It answers so many questions - why quantum physics and GR don’t talk to each other, what is quantum gravity, why we need to reconcile GR and quantum theory and many others. However I’m still not able to understand how space and time occur in LQG. I realize this is very complex, but after watching many many videos and reading many articles, I’m still not able to visualise it. Could you please do another more detailed video on this? I’m sure a lot of people would benefit from it. Thanks!
Excellent summary of both theories! Thank you Arvin!
Always great topics , thank you Arvin
Very lucid explanation of some very mind boggling concepts. Wonder if we will ever work out the full story of our Universe and how it interacts with other possible Universes?
I think this is the first video thata has ever made a single thing about string theory kinda click for me. I loved the brass instrument analogy
Uptil now , for me, LQG and string theory were just cool phrases to throw around...Now I have some understanding :D Thanks Arvin!
Amazing summary. Keep up the good work!
Hey Arvin, the closing bgm was great.
Fascinating that both mysticism from ancient yoga and modern mathematical physics have the same impulse toward unification. Yoga is a word that means "union", after all. Where does this drive to unification arise in our psychology? Science is often critcised as being reductionist, but this tendency reveals that the deeper drive behind analysis is synthesis of the results.
This comes to mind because both of these approaches to experiential understanding are beset with intellectual difficulties. Mystics are no closer to a unified understanding of how duality can be subsumed in nondual awareness, than scientists are to unification theory. Is this because of a logical contradiction, or is it due to the nature of experience, of reality?
The answers seem to be irrelevant to the fundamental human drive to unify the parts, in that both of these strangely motivated endeavors will continue even if some dogmatic ideology arises from experience which purports to prove that "unity is impossible" in the sense that it either does not exist or simply cannot be symbolically understood and expressed. Such as Godël's results on the incompleteness of arithmetical logic. If not even arithmetic can be freed from paradox, the physicists' program would seem to be inevitably downright illogical. Based on a faulty premise -- that a noncontradictory expression for a unified theory can be written or thought. In that case, the lack of a paradox-free explanation doesn't say anything about unification in actuality, but it speaks to our limitations as computational beings. The physics version of arithmetical propositional indeterminacy might read as something like "any mathematical expression powerful enough to describe everything in terms of fundamental forces is necessarily a generator of paradoxical statements that cannot be resolved within that same framework." ?
But at least the wet neural network of a yogi is more philosophically (or perhaps just psychologically) amenable to holding paradoxical concepts even while practising their art. This is perhaps the source of interest in mysticism among quantum theorists, and its popularity among non-physicists. Onward! Haha
Outstanding Alvin. Spectacular.
Very nice video installment, very easy to follow and understand. Thanks 👍
