Question, since gravity is determined by the mass of an object, and since e=mc^2 can be arranged to form m=e/c^2, does this imply that an object will have a greater gravitational force and hence will warp spacetime around the object to a greater extent, the greater velocity it has (due to the fact greater velocity implies a greater kinetic energy)? Or am I thinking about it wrong

Hello Eugene - thanks for this great video, I watch it all over from time to time, it is so fascinating. The only special thing is the background music being to loud over the nice lady's voice, especially when I try to concentrate... Thank you again for the nice video, really admirable!
Hey, the proper time is always the short one. The longer time (time dilatation) is the one that the "Earth" guys observes. Both TIMES are correct. Just like a car moves away from you, it gets smaller and smaller, but the car is always the same :) Hope it helps...
Hi, as a retired science teacher, I can say that this video is outstanding. It has made the understanding of General Relative easier to get one's head around the concept. Very well done. Nicholas Marino FL.
In the last part, doesn't sarah's clock run faster irrespective of whether adam accelerates or not. I have seen several videos where it says acceleration has nothing to do with it.
Dominic, the videos which say that acceleration has nothing to do with it are only dealing with Special Relativity. I am discussing it from the point of view of General Relativity, which is the more complete theory. I go into the details of this specific issue in my video on the Twin Paradox at ua-cam.com/video/bjHLboK2M1g/v-deo.html
@@EugeneKhutoryansky well I have a question. Why do we think that light's speed is same for all observers. Suppose that I am moving at light's speed now, so I will notice that light has stopped moving. So according to me light's speed is 0 but for other observers on Earth it will be still c. Where am I wrong?
I remember watching this video as a kid and falling in love with the beauty of physics and the background music, it gave me the inspiration to learn the piano and perfect it. Thank you for that.
How can time slow down inside a moving vehicle to rectify the otherwise inevitable - apparently - problem of 'light travelling faster than light speed which is, as a principal of physics, CONSTANT, if this would cause any light that started to travel inside the vehicle just before the vehicle moved to slow down and 'travel slower than the speed of light' which is, also, according to Maxwell's principal, 'impossible'? Plus, if light reflecting off OUTER surfaces of a moving vehicle would affect the light as a tennis ball 'slowly' hitting a speeding train would be affected in terms of its speed increasing on reflection without, that is, the slowing down of time OUTSIDE the moving train, then either time does not slow down outside a moving vehicle and Maxwell's principal is violated or time slows down OUTSIDE a moving vehicle - as well as inside - and Einstein's theory of 'relative time' is wrong?
@@JamesHenderson-ue5db I don't understand Maxwell equation but I too have doubt in theory of relativity. Can you please explain me Maxwell equation simply. I am not good at math.
It's actually good to see someone who actually knows what he's talking about doing such an elegant animation. Its been 6 years since I first saw this video. Back then I didn't understand anything. Now, with a physics degree I can appreciate it much better. Seen some of your videos. Please continue.
is it sad tho? its your interpretation of sad. but why do you interpretate these tones as sad? as far as we know there is actually no logic behind it. high slow tones indicate sadness? what in evolution has caused that if thats the case? i wonder.
@@hsaccount_ it's not "high slow tones". Anytime you try to associate an emotion with a rule in art you will find a counterexample. That's the beauty of art, we know if something is beautiful, sad, happy, dark, but we don't know why :)
Wow this is an excellent video. I go to school every day hoping my teacher's would teach me something like this but instead they bore me with the very basics of a plant for e.g label all the parts of a plant. I wish science in schools would be taken more seriously.
Lol there's no practical application for this unless you go into physics, and to actually understand this you'd probably need a few years of fundamental knowledge in physics, stop whining about school. (and maybe take physics instead of biology)

Hey. so If I travel at near light speed and time slows from hours to seconds for me ... does my biological body follows the time?. We can't survive without food and water. travelling for an hour at near lightspeed is equal to months on earth. how can my body survive?
I'm pretty sure time will be taken out of Space time. Gravity is just a physical effect on clocks and atoms making us think time has been changed, but it hasn't, as clocks are not the definition of time. Time marches on at a steady rate irrespective of the existence of clocks.
After 4 videos I finally understand it and it explains a lot about space. This video was by far the best as it did not just repeat Einstein's theory but actually explained it in a new modern way
you're right in my opinion. But i also like Leonard Susskind, Stanford University professor explaining the math: ua-cam.com/video/toGH5BdgRZ4/v-deo.html
Exactly ten years ago (I was 15 years old), I discovered this video. Before that, I am already interested in sciences and mathematics. After watching the video, I was mind blown and having existential crisis for a few days. From that moment, I started to read a lot of physics book and math book to be able to understand general relativity. I understood special relativity mathematically during my college majored in physics. For general relativity, it took me until now, my math is still not enough to understand it. I am currently a research student doing master degree in quantum dynamical semigroup. Without your video, it is hard to imagine to be able to get to where I am now.
Thanks. I am glad that my video made such a positive impact. By the way, in case you haven't already seen it, I have a video discussing the mathematics of General Relativity (Einstein's Field Equations) at ua-cam.com/video/UfThVvBWZxM/v-deo.html
A really simple, concise explanation of Relativity. I especially enjoyed the fact that you pointed out that because gravity is the curvature of space/time it is not actually a force. Gravity does not pull on objects. It is the curvature of space/time that makes objects traveling in a straight line in curved space/time appear to be pulled towards each other. I get so frustrated when I see very famous and popular scientific educators neglect to mention this. Instead they mention the curvature of space/time and then continue to describe gravity as a pull. I realize that it is an attempt to make the concept of gravity easier to understand but, in my opinion it is a disservice to true scientific education. I think even most layman can grasp the reality when presented properly as you have.
I see the dent and all, but one still assumes objects to travel "downhill" which is due to the preconcieved notion of gravity being a "pull" in the first place??
xXsakkelaoXx An understandable misconception as, given what we observe, your explanation makes perfect sense. In reality gravity would actually be more of a push that we receive from space/time itself. I don't know if you have ever seen one of those big funnels that you drop coins into and watch the spiral down into the centre? The coin rolls around the inside of the funnel because it actually wants to go in a straight line. However the "push" of the funnel makes it orbit instead. In this case a decaying orbit, but if you could get that coin rolling really fast it could acheive a stable orbit the around the centre.
James Toupin Gravity is a very mysterious thing, especially when you think of it along side space/time - here is an interesting thought, if an astronaut were to leave the gravitational curvature of the earth --- and he placed an object next to his mass that was say 1000 times smaller, or 10,000 times smaller, would that object then orbit him? If the answer is no because the mass is not great enough to "Dent" the fabric of space, Then you have to wonder if it is "Layered" and how big is each layer? The reason for me saying that is because when I think about it, if it was a consistent fabric then why should the sun be big enough to bend it? If the sun is, then surly an entire galaxy mass should be enough to cause a rather big dent which would nullify the effects of the inner dents? Also curiously if the answer was no, and you then accelerated the poor spaceman inside the galaxy along with his ball we will call "Wilson" haha to near the speed of light his mass would become big enough that the ball would orbit? and also if his mass accelerated to such lengths that it becomes near infinite if you had enough power that is... Then surly the denting of that infinite mass would throw off a few orbits of say, the complete solar system? The more deep you think about the subject, the more questions there are, personally I have always accepted the standard theory of gravity and thinking about it leads to endless questions, poor albert.
I understand the concept, but the question is why would it orbit so slowly? When the earth orbits the sun quicker for example? The obvious answer is Mass - Yet the sun is much smaller compared to the galaxy than earth to the sun, and in ratio the grain of salt compared to the man, so if you picture the indentation the galaxy must make, should that not make for example the centre of the galaxy's gravity a lot more dense and nullify anything holding orbit? the same as the earth nullifies our ability to have a grain of salt orbiting us on earth?
I love it how you connect your explanations with your atmospheric animations and the calming music. This way those topics regain the beauty that they deserve.
I don't know if Einstein can taught a 12 year old boy 'What is my theory of relativity'.But you did this . Great job..👌👌👌👌👍👍👍👍.I have never seen a educational video which can teach us this simple.
+AWarmCoffee yes dude i saw that movie over 4 time's probably, but cant understand the basic concept, after this presentation i watched another time, and i clearly understood ..
This was the video that got me started on my path to become a theoretical physicist. This video legitimately changed my life! But I have to say Eugene, you’ve improved tremendously on these since you made this. Ever think of remaking this video to remove some of the more whimsical bits or correct sections like the relativistic mass section?
@@seralelix There is nothing "wrong" with the relativistic mass section, but there are many people who think that the concept of relativistic mass should never be used. I discuss this in detail in my video at ua-cam.com/video/AU_O9yrgwhk/v-deo.html
I very much appreciate Eugene for such brilliant content on a topic that so hard to express. And for those of u who are still learning 2D, 3D and Vector Mathematics, just try to parallel transport a vector on the surface of a cylinder and a cone. U will the magic which Einstein fomulated in very complex Mathematics.
Interesting. Very complex, and to think a man thought of this, and disproved what everyone in that time thought of space it's self. this puts a good visual in my head of his theory, thanks for the video.
This is the best presentation in the UA-cam about special relativity in pure conceptual terms. Congrats. MGM (phd in Physics). PS. There is however a slip during a faster generalization about the (never named) twin paradox: to solve the (false) paradox of twins we never need to invoke the acceleration in order to show who really is the younger twin.
Thanks for the compliment. We need to invoke gravity for Adam to believe that he was standing still during the entire journey, including when he was firing his rockets. I go into much more detail about this in my video on the Twin Paradox at ua-cam.com/video/bjHLboK2M1g/v-deo.html
something about this video is so erie and mysterious. the music makes it that way.!! not to be overshadowed by the amazing information and knowledge given throughout the video! It is just perfect and i can watch it over and over and over again!!! Love it so much
Over the last year I have become a physics junky. Your videos were some of my 1st inspirations. Thank you for all your hard work! I can't wait for the next one.
I was like "oh I dont know what the theory of relativity is, Even though I have heard of it many times, I want to know what it is" Holy moly this is heavy stuff! Now I realized why Einstein is a known physicist and not me
I think it's the first (or one of the firsts) videos who teached me about basics of relativity, which is a kind of must-know knowledge for me now. I think it was few years ago. Now I had to go back cause I actually started to feel like the more I think about, the less I know.
I also realized I was stupid all these years thinking that relativity was an objective concept. I just realized that Einstein was expert in confusing objectivity with subjectivity. nothing changes in reality to an observer except their personal feelings. Nothing really shrink. what is seen shrunk to one is not seen shrunk in reality. I invite the learned commentators to reject me if you can. will appreciate. Shaw from USA
Love this video, best explanation and background Music, this video gave me the enthusiasm to understand Relatively in a more deeper way. I want to thank the maker of this video Eugene Khustorianski for such a Master piece which change my entire life forever about the understanding of the universe around me. Again Thanks
This is one of the best video to explain theory of relativity. I tried many sources to understand but this was the source which made me most nearest to understand Completely
Eugene Khutoryansky is humanity's hero! so much time and effort (not to mention sheer brilliance) into making these concepts accessible to the general public!
+Jonathan Jacobi I'm really gratefull for the explanation! Very interesting ! However i wished more than a few time during the video there was a stop button allowing me to stop the music and keep the commentary.
Hello Eugene I don't know if you know me but I learned the basics of these conspicuous theories from your videos . I started watching your videos from like 2 years back and I've found you again . I'm happy

I understood special relativity mathematically during my college majored in physics. For general relativity, it took me until now, my math is still not enough to understand it. I am currently a research student doing master degree in quantum dynamical semigroup. Without your video, it is hard to imagine to be able to get to where I am now.
Thanks. I am glad that my video made such a positive impact. By the way, in case you haven't already seen it, I have a video discussing the mathematics of General Relativity (Einstein's Field Equations) at ua-cam.com/video/UfThVvBWZxM/v-deo.html
A really simple, concise explanation of Relativity. I especially enjoyed the fact that you pointed out that because gravity is the curvature of space/time it is not actually a force. Gravity does not pull on objects. It is the curvature of space/time that makes objects traveling in a straight line in curved space/time appear to be pulled towards each other. I get so frustrated when I see very famous and popular scientific educators neglect to mention this. Instead they mention the curvature of space/time and then continue to describe gravity as a pull. I realize that it is an attempt to make the concept of gravity easier to understand but, in my opinion it is a disservice to true scientific education. I think even most layman can grasp the reality when presented properly as you have.
Thanks. I am glad you liked my video.
I see the dent and all, but one still assumes objects to travel "downhill" which is due to the preconcieved notion of gravity being a "pull" in the first place??
xXsakkelaoXx An understandable misconception as, given what we observe, your explanation makes perfect sense. In reality gravity would actually be more of a push that we receive from space/time itself. I don't know if you have ever seen one of those big funnels that you drop coins into and watch the spiral down into the centre? The coin rolls around the inside of the funnel because it actually wants to go in a straight line. However the "push" of the funnel makes it orbit instead. In this case a decaying orbit, but if you could get that coin rolling really fast it could acheive a stable orbit the around the centre.
James Toupin Gravity is a very mysterious thing, especially when you think of it along side space/time - here is an interesting thought, if an astronaut were to leave the gravitational curvature of the earth --- and he placed an object next to his mass that was say 1000 times smaller, or 10,000 times smaller, would that object then orbit him? If the answer is no because the mass is not great enough to "Dent" the fabric of space, Then you have to wonder if it is "Layered" and how big is each layer? The reason for me saying that is because when I think about it, if it was a consistent fabric then why should the sun be big enough to bend it? If the sun is, then surly an entire galaxy mass should be enough to cause a rather big dent which would nullify the effects of the inner dents? Also curiously if the answer was no, and you then accelerated the poor spaceman inside the galaxy along with his ball we will call "Wilson" haha to near the speed of light his mass would become big enough that the ball would orbit? and also if his mass accelerated to such lengths that it becomes near infinite if you had enough power that is... Then surly the denting of that infinite mass would throw off a few orbits of say, the complete solar system?
The more deep you think about the subject, the more questions there are, personally I have always accepted the standard theory of gravity and thinking about it leads to endless questions, poor albert.
I understand the concept, but the question is why would it orbit so slowly? When the earth orbits the sun quicker for example? The obvious answer is Mass - Yet the sun is much smaller compared to the galaxy than earth to the sun, and in ratio the grain of salt compared to the man, so if you picture the indentation the galaxy must make, should that not make for example the centre of the galaxy's gravity a lot more dense and nullify anything holding orbit? the same as the earth nullifies our ability to have a grain of salt orbiting us on earth?
I love it how you connect your explanations with your atmospheric animations and the calming music. This way those topics regain the beauty that they deserve.
dude the music on this video makes my heart cry and i'm a hardass normally
The music is so mysterious perfectly matches with the content shared in this video, I enjoyed it so much! Thank you and Einstein really was genius
I don't know if Einstein can taught a 12 year old boy 'What is my theory of relativity'.But you did this . Great job..👌👌👌👌👍👍👍👍.I have never seen a educational video which can teach us this simple.
thanks now i understood the interstellar movie clearly...thank you very much
Haha thats exactly why im here.
+AWarmCoffee yes dude i saw that movie over 4 time's probably, but cant understand the basic concept, after this presentation i watched another time, and i clearly understood ..
That movie was trash
No one, ever, past, present or future, understands Interstellar.
Exactly why im here rn lol
This was the video that got me started on my path to become a theoretical physicist. This video legitimately changed my life! But I have to say Eugene, you’ve improved tremendously on these since you made this. Ever think of remaking this video to remove some of the more whimsical bits or correct sections like the relativistic mass section?
Have u become a phisicidt... ? It's my dream too
yeah thanks to her ... for making me a theoretical physicist
@@ShankarKumar-bo8kc got to university
What is wrong with the relativistic mass section?
@@seralelix There is nothing "wrong" with the relativistic mass section, but there are many people who think that the concept of relativistic mass should never be used. I discuss this in detail in my video at ua-cam.com/video/AU_O9yrgwhk/v-deo.html
I have just passed 12 class, I understood 95 percent of all, that's great. Thank you for outstanding videos 🥰🥰
So many different points of views yet all correct.My mind is officially blown.
Why am I crying? lol
+Daxkalak Don't cry...its like what Joey said...maybe he cud date Sarah's super hot great grand-daughter. XD
This is.. a sad story of Adam and Sarah )-;
because you don't watch rick and morty
I know right!
Me too 😢
I want to like this video a billion times and definitely this video deserves a NOBLE PRIZE!!!
awesome video. this is literally the only time I have ever heard this explained in a comprehensible way.
Thanks.
I very much appreciate Eugene for such brilliant content on a topic that so hard to express.
And for those of u who are still learning 2D, 3D and Vector Mathematics, just try to parallel transport a vector on the surface of a cylinder and a cone. U will the magic which Einstein fomulated in very complex Mathematics.
Can U Pls explain again What to do??
man sarah should stop stalking adam. : p
Some people might appreciate someone watching over them
i enjoyd the entire video, except the sound of the balls bouncing...
+Anand Pathak yes THANK YOU
it wasnt gay until the balls touched
Still the best explanation of the principle I ever saw.
Спасибо вам за это!
This was the most mindblowing video I saw in a long time
I never knew Relatively Theory was so sad.. 😢😢😭😭
A sad love story 😩
😂
🤣🤣😄👏🏼👏🏼👏🏼
Same...this video made me weep 😭
relative to what?
Life is short in relative to universe.... Read about Islam
Interesting. Very complex, and to think a man thought of this, and disproved what everyone in that time thought of space it's self. this puts a good visual in my head of his theory, thanks for the video.
Robby tty I am glad you liked the video. Thanks.
I still watch this every year. Absolutely great video!
Thanks.
I love this video, the combination of the scary music and these interesting and bizzare things makes me scared and amazed at the same time
Poor Adam. He's stuck in a spaceship with just a bouncy ball.
hahahahahah, you made me laugh so much!
Perhaps he should name It Wilson.
and sarah is a evil physicist , who never rescues adam.
Hell of of a bouncy ball! I'd love to have a bouncy ball that big!
What a video!! I think every student should watch this video It creates curiosity in mind.👍👍👍
It mind blowing reality
Curiosity is infinite so is universe☺️
I love you Harshita Verma
This remains the best video I have ever seen on UA-cam. Thanks 🙏
Thanks for the compliment.
This vid is a straight BANGER. Super classic
Relaxing and awe inspiring. Brilliant!
Great video, but that piano song.. mannnnnn Is like a time travel to my bed.
This is the best presentation in the UA-cam about special relativity in pure conceptual terms. Congrats. MGM (phd in Physics). PS. There is however a slip during a faster generalization about the (never named) twin paradox: to solve the (false) paradox of twins we never need to invoke the acceleration in order to show who really is the younger twin.
Thanks for the compliment. We need to invoke gravity for Adam to believe that he was standing still during the entire journey, including when he was firing his rockets. I go into much more detail about this in my video on the Twin Paradox at ua-cam.com/video/bjHLboK2M1g/v-deo.html
something about this video is so erie and mysterious. the music makes it that way.!! not to be overshadowed by the amazing information and knowledge given throughout the video! It is just perfect and i can watch it over and over and over again!!! Love it so much
Thanks. I am glad you like my video.
why do your clocks go up to 13?
+MrErmmmmmm 26 hour days are the future, get with the *times*
+MrErmmmmmm I like the 13 hour clock!
He was joking :). Why the clocks go to 13 is still a mystery.
Who cares, it's a great video. If you really want a theory, however, perhaps it is to illustrate the point that time as we know it, isn't absolute.
..Russia..Great Cosmonaut Technology..
Over the last year I have become a physics junky. Your videos were some of my 1st inspirations. Thank you for all your hard work! I can't wait for the next one.
Thanks. I am glad you like my videos. I am working on the next one right now.
This is probably the best video on UA-cam that explains relativity.
Thanks for the compliment about my video.
Congratulations! It's the best explanation I've ever seen. Thank you so much
Exactly
I was like "oh I dont know what the theory of relativity is, Even though I have heard of it many times, I want to know what it is" Holy moly this is heavy stuff! Now I realized why Einstein is a known physicist and not me
Everyone : Relativity Theory is so sad
Me : wait, what that clock have 13 numbers
numbers*
because fliying 12hours at light velocity = as being still for 13 hours
Yeah I didn't noticed that.
I think it's the first (or one of the firsts) videos who teached me about basics of relativity, which is a kind of must-know knowledge for me now. I think it was few years ago. Now I had to go back cause I actually started to feel like the more I think about, the less I know.
This is the clearest explanation on youtube, thank you
Thanks. I am glad you liked my explanation.
This explained the whole concept of relativity. I really don't have any words to thank you!!
I also realized I was stupid all these years thinking that relativity was an objective concept. I just realized
that Einstein was expert in confusing objectivity with subjectivity. nothing changes in reality to an observer
except their personal feelings. Nothing really shrink. what is seen shrunk to one is not seen shrunk in reality.
I invite the learned commentators to reject me if you can. will appreciate. Shaw from USA
"Adam's ball have more mass" ata boy..
HAHAHA! Underrated comment!
Including eveything
Best video about relativity I've watch this far and it's completely self contained
Thanks for the compliment about my video.
Love this video, best explanation and background Music, this video gave me the enthusiasm to understand Relatively in a more deeper way. I want to thank the maker of this video Eugene Khustorianski for such a Master piece which change my entire life forever about the understanding of the universe around me. Again Thanks
Glad you liked my video. Thanks.
Absolutely brilliant explanation.
Thanks.
Good explaination, but the music was a bit too depressing...
The music is the best thing
And loud.
Mysterious afterall..😅
it was like a horror movie
the music is NOT depresssing , Its just russian music . SOVIET POWER .
Wonderful !!!
It's very clear,. Love it !
I was regarded as the "smart kid" in school but even I can't understand any of this without your videos.
1:47 That fourth observer sure has great vision when he is able to see the sun from outside the galaxy XD
At the place of eyes, thier were highly advanced telescopes.
This is one of the best video to explain theory of relativity. I tried many sources to understand but this was the source which made me most nearest to understand Completely
You explain it so well! Thank you.
Music and theory - both beautiful.
Nolan gets the idea to write interstellar from this video😂😂😂
Just watched it… went to this video to understand it a bit better hahaha
True man 😂
I came here for the music. The theory is just a bonus
What about the love story?
J
Same
Lol
Which music is this?
와! 과학공부하는데 정말 모르겠어서 찾아봤는데 이해가 잘대서 좋아요! 한국어 자막 감사합니다! Thank U😊
Very very well explained!
Thanks Mr Eugene 😊
Simply fantastic!
I knew many of the explanations already but now it added some more!
superb yl....
It was good....explanation.
even though I still have many confusions...
Eugene Khutoryansky is humanity's hero! so much time and effort (not to mention sheer brilliance) into making these concepts accessible to the general public!
Thanks for the compliments!
Great presentation with a facinating soundtrack.
and from my point of view... I got headache!!
Me too, I feel like I understand what the video is saying, yet don't quite understand at the same time.
+Danny Dziedzic exactly
LOL.. Mind blowing... I wached it 3 times already and still blank
lol me to i can understand parts of it alone but when i try to connect it all together i get lost
watch interstellar
why sad music tho
lmao
+Johnathan Jakkobi Makes me sleepy ^_^
Because it's too interstellar
+Jonathan Jacobi I'm really gratefull for the explanation! Very interesting ! However i wished more than a few time during the video there was a stop button allowing me to stop the music and keep the commentary.
K Le blanc I love the music, it makes me calm and sleepy :P
Jonathan Jacobi it's because Adam and Sarah didn't work out
this video explains it very good! every think makes so much sense now thank you so much
Hello Eugene I don't know if you know me but I learned the basics of these conspicuous theories from your videos . I started watching your videos from like 2 years back and I've found you again . I'm happy
Thanks. I am glad you like my videos and that they have been helpful.
The moment Einstein realised Time was a variable he must have felt like God himself!
Time is a dimension. How fast you move across it, is a variable.
@@new-knowledge8040 🤣
Time is relative not variable😂😂😂
He realized that he had only just begun to see the very very basics of how God designed the universe
Einstein realized he was right.....when he gaged the wave equations under lorenz boost. He was so right...........
A brilliant explanation and by far the easiest to understand. Have subscribed and will pass it on. Thank you for posting.
Thanks for the compliment and glad to have you as a subscriber.
Started reading Einstein's Relativity and this video is helpful indeed. Thanks!!
Glad it was helpful. Thanks.
Love the animation, really lives up to the manga
the ball sound startled me like woah
+Jennifer Turner lol me too i was watching this in an quite afternoon xD
The first video that started to piece it all together for me; several Stephen Hawking (and other) books later and I still see why this explained it all to me in the first instance. Thanks for uploading.
