Every night i go to sleep watching youtube, doesnt matter what im watching, i will wake up in the middle of the night to this video
Dude... same.
Same happens to me on a different video, similar subject matter, usually Sean Carroll videos.
@@ryanhaller8896 6k
I fell asleep watching youtube and this was the last video that had been played. Maybe it's youtubes way of checking if we're asleep
Same here, crazy. Why?
I wanna confess something, Brian greene's youtube content helped me get out of depression, honestly
good to hear man, hope ur doing well now!
He has that effect on people, so I hear.
Okay, I didn't hear. I have bipolar disorder and when I'm depressed, learning more about relativity and quantum physics from Dr. Greene is one of my goto methods of getting out. That and cheese spread with sambal on bread and watered down banana juice. I just love that crap XD So if I don't feel like drinking or eating I eat and/or drink that and the taste makes me want more. Physics is just exhilarating. It takes little effort to sit down and absorb it and it just makes me happy and not even a depression can stop that from happening. Like my cheese spread and banana juice but for the brain.

@@MyKneeHurts i
Seriously though, this lockdown has brought me to more science contents to watch. We have Brian Greene, Sean Carroll's podcast with lots of leading scientist in physics or other topic, and also Royal Institution videos.
Best delivery of a time dilation explanation ever.
Couldn’t leave til the video finished, totally glued.
Awesome Dr Greene. Awesome and inspiring.
Thank you for sharing this. Brian Greene is just the best science communicator. Sometimes im so thankful for RUclips.
Yes AMAZING VIDEO ❤️❤️❤️
Praise the lord
Can you imagine what we could accomplish if we all had teachers like Brian Greene?
The secrets of universe
Flat earth people wouldn't exist.
We should clone him. A million Brian's should be enough to shift the pendulum in humanity's long-term favor.
Hopefully find a better theory then sting theory
what are you talking about , he's right there. can't you see? we have him as a teacher? What's holding you back?
Isn't that a miracle that we can watch this incredible lecture by world's leasing physicists for free at any moment in spacetime ! We are so lucky !
agree
I agree

@@socialmeaslesinpartnership1252 then why are you here? Over 2 hours you either didn't watch it all, or were interested in it enough to watch it.
Wait to watch mine
Greene as a teacher to a layman like me is breathtaking, phenomenal and rare to encounter. Almost if not entirely one of a kind. I say entirely because this gifted teacher just gave a lecture on a difficult subject to understand to a non-physicist and n0n-mathematician just like me: the conceptualization of Special Relativity. Nobody in my book has explained Special Reavity and what it means in practical terms the way Green has. Outstanding!!!!!!!!!!!!
Greene is good, DeGrasse Tyson is great, Carl Sagan is the one you should be looking for; "Cosmos", my young Padawan!
@@stevemuturi965being dead, Sagan won't be able to reflect a current understanding of these topics. And even at this dumbed down level, some important details of the interpretation have changed since Sagan went away.
I was told if you can't explain the general concept to a 12 yr old it may be completely wrong
@@josephsmith6777 that’s more about the depth of your understanding and your ability to explain it at various levels. It doesn’t mean that any truly accurate model of the universe is necessarily going to be fully comprehensible to any human, let alone a twelve year old. The universe owes us nothing. And our brains were shaped by an evolution to be just good enough to enable us to pick fruit, hunt wild game and get through an ice age. There was nothin in there about being able to perceive ultimate reality.
@@ralphclark no but u can explain the solar systems basically to a 12 yr old I learned newton's equations in 7th grade so the same way green describes huge equations and the connection to live experiment the basics aren't terribly hard to explain 😀
The first book that ever properly made sense to me and got me hooked onto Physics is The Fabric of the Cosmos! Thank you Dr.Brian Greene. 😊
Now hooked come check out The Resonance Science
If constant velocity is the same as being at rest for things made out of matter having mass, then why would light behave as if it was at rest if light has no mass?
What a waste of money.
What a gift Brian Greene has. He can explain this kind of thing in ways that mortals like me can perfectly understand ! Thank you Brian !
I agree emphatically !
I agree. However, I wish he wouldn't say meters per second and then say miles per HOUR. It confuses my addled brain. 😉😅
Immortals are still perplexed.

Mm
Keep in mind that he is a mortal as well.

Y u.
Einstein was a musician.
Many of us still do.
The majority of people though, oh well... Let's just say they are a bit simpler and leave it there, before someone takes offense at my words. :D
@@gerardcousineau3478 Einstein was actor, who played role of original author of his theories, while they were result of long process of groups of peoples who cooked them in back kitchen.
That is why he was not involved in group projects like Manhattan, and never be in proximity of others like he not became guide of any student for doctrate while working in universities. Many things quoted or attributed him to made image of him as genius, too much publicity is needed to conceal flaws. Things like his brain was bigger so more intelligent, later it proved that there is no such correlation. He done his thesis under Minkowski who was already working on relativity with others like Poincare, Lorentz to fulfill ideas of Maxwell.
Only If I had more teachers like this.
Your teachings are excellent.
I have never ever had a physics class like this.
My professors would always bully me with students.
Everyone needed a professor like him, someone who lives a good speaker and could keep you interested in the subject.
@@cynthiashepherd7754 Yes, indeed Cynthia Shepherd.
Hi. Prof. Brian Greene. In the beginning, recently, I watch your program by chance. But now, I am hooked and become your staunch follower. Your lectures are very interesting and enjoyable even for someone who does not have any background in physics or cosmology. I feel you are giving lectures on cosmology like reading a poem. I love it, sir. I am watching from Thailand.
I am somewhere watching between the East and the West: relatively in relative world views consideration for "change" vs. for measuring what is the highest value cross culturally or what it means to "know" something (epistemology), Orr what is logic as understanding "process" by the axiology of our values as may be seen by the cohesiveness of the group herein as astro physicists non-technically!
The major world views hold axiology to advance questions of what is the highest value cross culturally, what does it mean to know something, snd what is change, and what is logic. The psycho linguistics in aspects of cultural differences suggest the Whorfian Hypothesis ststes that no two people have the same view of the real world view in the same way unless their linguistic backgrounds are similar. The Mustrician Hypothesis goes deeper to suggest that Man has to rationalize his existence and does so through linguistic orientations. Perceptions abstract information within human ranges potentiated by technology herein as astro physicists to chase light. Our puny brains have abstracted therein the s Standard model being a theory for s partical physics requiring CERN is the top of the arts and sciences. Here process for our world view defines technology.

I am confusing myself. Please help.
I have read, I believe, every book that Dr. Greene has written. There is simply on one on the planet who can explain complex subject matter in a manner that even I can understand. Thank you, Professor Greene, for allowing me to see and appreciate the wonderful universe that we all inhabit.
Brian Green is by far the best public speaker on RUclips. Flawless as a salt crystal.
Brian, I'm speechless. For the first time in 30 years, I get it. This is the clearest account of these ideas on the internet.
LOL. It’s the worst I’ve ever heard. But if it allowed you to figure it out then good for you.
His books are great
Sir, you are one of the few persons who actually make one love physics.
Thanks a lot sir.
@Enter the Bragn’ what is it then?
Enter the Bragn’ You are so stupid...
Enter the Bragn’ You don’t even deserve an explanation
@Enter the Bragn’ if space and time is one - and space is something physical then surely it qualifies as "physics" by your own definition, dosent it? Idk are you looking to distinguish the difference between physics and theoretical physics?
I'm just eager to understand🙏🏼
@Enter the Bragn’ ive been searching a little around and is still confused but i found the claim -
"In physics, spacetime is any mathematical model which fuses the three dimensions of space and the one dimension of time into a single four-dimensional manifold. ".
so its a type of model within physics but not actual physics because of only having physical attributes? and if so, what category does it then fall under?
He is brilliant, 73 year old here always trying to understand space/time
I’ll be rewatching this for a while. Great lecture, I always enjoy listening to Brian.
Give Albert Einstein the respect and credit he deserves for piecing all the concepts together, if, he hadnt thought of it himself.
He stole it all and still got it wrong. Einstein was a Useful Idiot just like this woke idiot and wrong about everything. Now you are dumber for watching.
I never went to high school. Theoretical physics, subtopics particals,, quantum theories attract my imagination n I'm so grateful these videos explain so much of the questions I've been asking myself for years.
Do not worry, even if you would have gone at high-school, the rotten teachers and fked up no life kids who's parent never bothered to help them make a difference between right or wrong and much more, would have sucked out everything good from you, just do you and learn now with the tech at hand, what you really like, every word every sentence you Don t understand from these kinds of videos, just search them and see what they mean, memorise it and go on to the next YOU thing.
I know what you mean. I left school without finishing grade nine to go to work. RUclips is school these days. I remember having to go to the library to look for things I wanted to learn and even that in itself was a challenge. Now in just a couple minutes I have a choice of ten specialists to choose from to show me what I want to know. Such a wealth of information.
What is theoretical physics to you? What counts as gravity and a valid theory for gravity?
You were great in Rocky.
university = memorize training center
bring something new to the science : )
The visuals are incredible! I can listen to Brian Greene for hours but these visuals are really next level 👏
The more I learn the more I realize how much I don’t know. I have three degrees and bunches of letters following my name, yet I know so little. Thank you Dr Brian…you are the best. I’m continuing to learn.
Life’s a journey. Knowledge is great. Increasing your knowledge is great. Learning is great.
That was precisely Albert's sentiments, until he met Mileva Marić 🙄
@@ultrakool 😊
As long as you don't have a "D" behind your name, that would make you very closed minded.
gravity was a downward force on 9/11...but then on all other days gravity is not a force
If I’d had a science teacher like Brian Greene I’d have a PhD in physics
Amen
no you won't.
You’d still have to write the exams, and know how to solve the equations ;)
But hey , I don’t know you. You may be very smart and good at advance math .
@@DHT2023 no she/he won't be PhD for sure. based on reaction to this very basic lecture she has no fucking knowledge of physics nor she could ever go to level where she can get PhD in physics. this very very basic entry level physics lecture.
@@amazingdude9042 u dont know wtf ur talking about
For young aspiring physicists like us, it is very essential for people like Dr.Brian Grene to inspire us and
Equally, from our side is essential to get inspired by them; to not only keep our in touch with our subject, but to keep the flame of curiosity burning inside too.... I'm deeply grateful for this sincere effort Sir.
I will do the same soon
I am not a science student but Dr Brian Grene's amazing knowledge in physics and of relativity and simplicity of his explanation gives me some insight of the subject . It interests me very much . Thank you Dr very much.
Amazing I think I understand time dilation on high level now. Thanks, Mr Greene. What a treat.
I'm watching from South Africa, Durban. I am enjoying your lecture, I'm going to actively seek more of your work as you have a layman's way of explaining rather complex scientific concepts
The difference between a poor student and a brilliant one is the teacher. Brian was not only a brilliant student, he's an excellent lecturer.
I read " Brain is not only a brilliant student..."
@@E-Kat yea got it..👌
You should tell that to Kanye
That is really really not true. Every theoretical physics student does not have a great teacher. In fact most of us have really shitty ones. But we get by just the same.

Dear Processor Brain Greene,
I love physics and I'm sure there are at least 1 lakhs students like me who love physics too but the way our teachers teach us is rubbish...they let us to see the beauty of marks, jobs, career etc.

Thank heavens for teachers in his vain. They are very few and extremely far between... We love ya Brian!!!

Sometimes we understand concepts perfectly well but have difficulty articulating them. So your statement that he explains best because he understood it best is not always true. Some people just have a gift of explaining things in a better way.
I wish we were taught like this in college :(
We were mostly cramming things without actually understanding what's going on. This video is totally amazing!

One of the best videos on internet... I came here thinking let's watch 10 minutes, you held me captive throughout the session.. I just hope time ticks slower on ur 🕒 and u get lot of time to teach many people...
Great metaphor. Live long.
Don’t try to prove the metaphor though.
Excellent lecture by Brian Greene!
I love relativity and now we have this precious video forever to watch over and over again. Thank you Brian!
Absolutely! I have in my 58 years feel 'Finally yeah thank you.
Brilliant
One of our best physicists!
Thank you Brian for giving me hope that maybe I’ll understand this one day. I’ll listen to this another dozen times and get back to you!!
From my perspective, the most amazing aspect of this lecture is that if forces you to rethink your entire concept of reality. At 74, it’s not so easy.
Same here, but I'm 83 so time here is different.
Ya same and im 103
I at 77 too am impressed.
Amazing presentation. Very clear and no um's or uh's. A true masterpiece.
Once again thanks for RUclips and its content creators...access to videos like this are often more instructive than classroom college lectures on the same subject. Yes, I could do with less of Professor Greene jumping around on a stage, but that seems a small price to pay. No, this does not replace the in person experience of going to an institution of higher learning but what a boon to the rest of us who are no longer in school.
I am now an addict of his lecture, professor greene is a legend, who made physics fun and easy..
I love falling to sleep with these ideas....its very relaxing.
I do too
My everyday routine!
Me 2.... N I suck at math...,🤷😉🤘🏽
The best way to fall a Sleep!, 💪💪
Doing it right now
Brian Greene is such a great educator!
The passion of this dude amazes me every time I see him speak.
The more I watch these videos and ask these questions, the more I realize nobody really knows why. I've been beginning to accept the fact that it is just true and can be measured consistently. These are just properties of reality. I spent my entire lifetime trying to wrap my head around this stuff but I think today I finally get it. I can finally see forward and backward land.
Genius
Why: because it’s a lot simpler than not being this way. When quantized, it enforces particles be boson or fermions, with the latter being matter.
Brian is such a great teacher and speaker.
Great video. Thank you.

Is it coincidence Brian Greene is the spitting image of a young Albert?
Brother, I've been following you for 16 yrs. This is by far your most susinct and penetrating lecture. Bravo!!! Thank you.
I have enjoyed Brian Greene for years . Thanks you tube.
There is something so soothing about your teaching - its easy to follow and you have a way of keeping our attention
I’ve been learning stochastic and differential calculus for financial quantitative analysis and took a break to watch this video. I completely forgot myself for those two and a half hours.... I’d always heard of these equations and watched Interstellar several times but never really understood the concept with a high degree of comprehension until now. BRAVO man 👏 this was extremely spot on, and I can’t believe anyone would dislike the video. I never though calculus would come in handy in the real world until two situations in my life: 1-the decision to become a quant, and 2- my new found obsession with time travel and time dilation in general. To quote Family Guy, “why are we not funding this?!”

Amazing lesson and awesome teacher. I felt like I finally have someone who knows the answers to my questions before stressing a thorough investigation on my own paths. I still have so many questions on this topic, but I know now that someone like Brian Greene can just keep answering them so helpfully and usefully.
Being a science student and a teacher (in a different field) can vouch on the beauty of your arrangement of thoughts and delivery of the subject. I never grasped the theory of relativity as clearly as i did today. Imagine my concentration to have realised after 1:30 minutes of continuous watching.
Good job!
Thank you Brian Greene. Thank you. That was so eloquently explained and in such an entertaining style that, at least IMHO, you leapfrogged past Sean Carroll, in terms of communicating your craft to we others (less gifted), and in doing so you help to enlighten us all both now and, hopefully, our prodigy sometime in the relative future -- either through our sharing of what we just learned or via osmosis through our DNA to theirs perhaps. And think of how much better we inhabitants of this planet might be if we all could see it, and everything else around us, through Brian Greene's eyes. Not necessarily his perspective mind you (pardon the pun) but through his eyes. I do have issues with his perspective and interpretations at times but there is no denying his incredible ability to pass-on to us these wonderous things such as this which is shared in the lecture above. Again, thank you Brian Greene. Poles and barns .... lol. Incredible.
Through his eyes literally means from his perspective.
Thank you so much professor Greene. I love the way you explain thing
I like the way you explain the science, Brian Greene.
What a wonderful lecture!!!

Thank you.....
Dr Greene thank you so much for taking the time to create and share these lectures! Please please more, my brain is hungry!
And THAT is what makes a "teacher" of his caliber worth 1,000,000,000 professional athletes. I'm SURE he's not "in want" of $$, but there is NO AMOUNT that is unreasonable for somebody like him. It DISGUSTS ME what professional athletes make compared to gifted teachers, or others in this world who have equal "gifts" and make TRUE CONTRIBUTIONS TO SOCIETY vs. playing childrens' games for millions.
I’m starting my junior year as a physics major this semester, and while I’m used to seeing all these crazy equations that we have to try and solve like Schrodingers, Lorentz Transformations, etc, it’s nice to be able to clearly and simply understand what exactly I’m trying to solve rather than being fed all these letters and numbers and being expected to be a master of special relativity or quantum mechanics and the like. Thanks Brian!

Amazing. The effort that went into this production to convey science to the public, does not go unappreciated. Personally it extends past my understanding, but it fills gaps in knowledge that would have previously gone barren. Anytime Brian Greene or Sean Carroll or Dr. Tyson or anybody connected to radio astronomy, physics, Astro-physics, JPL, Nasa, Space telescopes, is in the Title,,, I'm watching it.

Thanks for the great video, loved every minute of it. Brian Greene is a great teacher.
I love his use of graphics to make the complex understandable. Fascinating.
At 80 years old, I wish that I had my younger brain again when I watched this tutorial by Professor Greene. .
I don’t have a professional science background, but after watching this I feel like switching streams and pursuing a career in the core sciences :)
I fall asleep to this all the time - I wish my brain would just absorb all this awesome info when I sleep but alas I still struggle to comprehend all of it! But Greene is such a good teacher that I am finally getting a lot of it!
I have popped the popcorn, flavoured the popcorn, baked the popcorn and right now I am eating the popcorn and I am loving this.
At 3:16 and he is such a great teacher. The key is to learn slow and in detail and with basics cleared / strong basics.
His tone is soothing, and his lecture is clear.
Brian Green inspired my love and passion for science.
Thankyou so much sir.....our favourite special relativity course.
Profesor Green Thank you for the photon clock example. Been wondering for 50 years weather time dilation was wrong or just all the examples were wrong. You provided all the math in so simple a manner that I could understand clearly that I had missed nothing as you proved clearly the problem. The light photon in each clock moved the exact same distance. Since it takes the exact same amount of time for both photons to move the exact same distance there was no time dilation only one clock was not up to the conditions it was placed into, so it reported 1/5 the time but your math proved that the clock was not reporting an accurate measure. Both photons traveled the exact same distance :)
Thank you so much for your awesome example and for doing the math in so clear and simple manner. Following up by showing this simple ratio was in fact in line with the fancy math let's me finally put this issue to rest. Clocks may fail but time is as consistent as photons are.
Amazing explanations....l still have to listen this a few more times to comprehend. Very good teachings . physics......not easy to grasp for me😮Thanks
Inspiring Lecturer , not all keep everyone s attention as well as You have full duration of presentation 👏👏👏👏👏👏👏
Dr, Brian Green. You are the best teacher I ever had the pleasure to learn from. I am old but there were things I had trouble grasping. An now it is clear to me. I watch all I can, you are the only one who describes and shows results. Thank you. Ray Parker
In the beginning of this video, my mind broke many times proportional to the tick tocks on the stationary light clock but progressively healed at the rate of the moving tick tock upon multiple viewings and that was awesome to build this foundation of knowledge , incredible instructor !
Congratulations to all of you who understood this explanation. The bouncing beam in the light clock broke my mind.

Fascinating and inspiring to watch him lecture. The dictation he presents is profoundly admirable.
Thank you for this. Really interesting. I never learned Math at school - stopped at Arithmetic, so really appreciated the great examples.
