The best geodesic explanation I've seen is with paper strips. Orient the strip so that neither side folds or leaves the surface - then you have a geodesic. Putting a straight line around a cone won't work, the side of the strip towards the narrower cone end will not make contact with its surface. It's effectively the same idea as the car wheels, but easier to simulate hands-on!
@@canyadigit6274 Motion is relative... From the perspective of the fallen object, the entire Earth is rushing up and hitting it and from the perspective of the Earth, the falling object is moving towards the ground and hitting the Earth... No reference frame is more true; than the other. Let me ask you this: Say you are inside a rotating room (an empty room with no windows or doors that just rotates around its central axes) Now inside that room you find a tennis ball. You pick it up and you throw it to the opposite wall, what would happen? Will the tennis ball go straight and hit the wall in front of you (since you threw it straight) or will it take a 90 degrees curved path to the right and hit the wall to your right? (or left depending on how the room is turning...) The answer is the latter. The tennis ball will take a curved trajectory and it will not go straight. And you might ask: "why does the tennis ball go to the right when I'm throwing it straight?" That's of course a bad question, because the tennis ball IS NOT actually taking a curved path, its YOU inside the room that is, that see the tennis ball take that curved path! The tennis ball was always going straight, it's only your own motion that made it look like it was curving. Like here: ruclips.net/video/bJ_seXo-Enc/видео.html Now imagine the same idea but with "gravity" and in 4 intrinsically curved dimensions of spacetime and that motion that you have (the one that is equivalent with the motion of the room spinning) is in TIME and not in space! Imagine all of that and you have Einstein's picture of "gravity" and you also have the answer to why Einstein considered this his greatest thought: "A man in freefall will not feel his own weight" No, objects in free fall are not falling, they are not moving in space because there are no forces acting on them at all. The reason why we *see* them fall, is because we exist inside a curved spacetime but we "don't know it", our senses "don't know it" and they in fact interpret our curved minkowski spacetime as a non curved euclidean spacetime. The only way for a human to see reality as it really is, is to go somewhere, where spacetime isn't curved. And we have such a place, it's called "outer space" away from any Star or other Planet sized massive object. There spacetime has a very low curvature, and there, when you let something fall you can clearly see that is not moving in space. Here on Earth is still not moving in space, but our senses by interpreting this world as an euclidean one, (and not as a mikowsky curved one as they should) see the object fall when in fact it's not falling. ruclips.net/video/QyeF-_QPSbk/видео.html :)
6:50 "The geodesics that are swallowed continue to spiral downwards" that's only if there is no bottom to that hole. If there's a bottom at any point, the geodesics will return. So, if we ever see light emerge from a black hole, could we use that to calculate the spacetime structure?
Something similar to this could be a pulsar which is an object that collapses but doesn't have enough mass to create a black hole, spitting it's matter out in polarized jets and spinning hundreds of times a second, but are 20km across and almost the density of a black hole. Check out the NASA mission IXPE cause we'll get some insane data we've never gotten to explore before when it launches in about a year.
But scientist says the information that gets into blackhole will be destroyed, so if you fire a beam light in to a blackhole maybe when it exits the blackhole it will be in another form or something...Idk
The car analogy attached on the surface gave it away for me! The wheels rotating with the same speed, cover different distances due to the curvature of the surface and thus the car turns accordingly but always moving fwd thus covering the least distance!
@@wilcovdberg You are right however that if you model gravity as a 'pit' in a surface, less velocity in a direction that escapes it will cause an object to fall earlier

Amazing presentation. The accuracy of the graphics and narration kinda split at the end, which is understandable 😇 it’s also easier to learn when our minds start to fill in the blanks.
"Special considerations must be taken when applying this concept to the higher fourth dimensional space-time of general relativity and this will discussed later in the video" *is only a 10 minute video* It's gonna be a good one.
"Straight" is an _ad hoc_ qualification that you have to specify when doing differential geometry; e.g., if you're doing the ordinary Euclidian geometry, two "straight" lines are "parallel" if they conform to Euclid's fifth postulate, and vice-versa...
0:37 Oh yes it is only deflected by a small amount I totally don’t see two angles opposite of each other Ps 5:54 The reason why they end up converging and diverging because one is positively curve and one is negatively curved.
The Dark Knight when the potential is zero: the only force present is the force normal to the surface: this doesn’t affect the Kinetic Energy hence the Kinetic energy remains constant: hence the speed remains constant
Gravitational time dilation tells you that distant frames in a gravitational field will begin to appear to move relative to you (they will accelerate relative to you) because rather than moving entirely in the time direction through spacetime, they will lose some of their 4-velocity in the time direction, relative to you, and transfer that 4-velocity to a spatial direction, this all appearing to you as a gravitational force pulling these object through space, and slowing them down in time.
Since both happen simultaneously, it is not entirely accurate to say that one causes the other. It might be more accurate to say that gravitational attraction CAN be explained using time dilation. It may be possible to do the reverse, but we do not know of any such way. So in the models that we have built, it appears that time dilation is more fundamental. But, there might be other viable theories (which we don't know of) that could explain time dilation as a consequence of gravity. Or maybe, both are emergent from something else entirely.
Last time I was this early people thought time was absolute! I love the title of this video, it shows you don't only appreciate math as a tool but also as something that can be aesthetic and fascinating
6:16 I think that sheet can imagined as a distortion in Space created by black hole and that lines as a light And I think this explain why light cannot escape from black hole but some of them can escape after spinning around it ?? *IDK I am right or wrong ?*
Imagine if you had to observe physics from a two dimensional plane. I feel like that's what's going on with black holes from our dimensional perspective. There's a direction we just don't understand 🤷♂️
How do you create these animations? They are simply stunning. Imagine if we had these showing in every school, and if all physics was taught in this way. You are creating something powerful, hats off to your efforts!
I've tried for months to compute the geodesics on a general ellipsoide (x/a)^2 + (y/b)^2 + (z/c)^2 =1 with a b c all different between 2 arbitrary generic points. Your animation shows the geodesic to wrap multiple times around. I had not considered that.
Why Eugene's video are amazing: Spatial representations of concepts Color-coding to differentiate between different elements Contextual verbal guidance
In my geometry class, I am pretty sure we defined geodesic as the shortest path between two points, so I have a hard time understanding 3:30 - did I understand nothing of my math class(probable) or at the physics and math definitions different?
Eugene Khutoryansky, we want to know more about you. Please give some information about where you seek your knowledge! Are you a professor? Do you own a degree? What do you do for a living? Very curious fan here just wondering

Your videos are so calming. The music fits perfectly with the amazing animations. And your voice is also calming. You'd think that would make the videos less interesting, but it really doesn't. It makes them a good way to get in a good mood while learning about math and physics.
When talking about General Relativity with people I've explained that the curved time component is what explains gravity. Everyone thinks I'm the crazy one LOL. Thanks for making this video, it's such a great explanation. Understand concept first, then it's pretty easy to grasp what the math is doing because it's no longer abstract!
I do like these videos, but personally I think they'd be better with a bit less 'down time' and, relevant to this video, not repeating the same sentences, I feel if someone doesn't understanding something there's always the rewind button, but if you skip forward you might miss something. Thankyou for making these videos though! They really do help make more tricky concepts easier to grasp!
6:20 i believe it's a good model of the event horizon, the light that managed to escape from the gravity, and also the light that was kept inside the black hole.
Huninin şeklini tepe noktası kütle merkezi olarak düşününce kütle çekiminin nasıl çalıştığı hakkında gayet net bilgi veriyor.Huninin tepe noktasına doğru hareket için gerekli alan azalmıyor çoğalıyor normal alanda gitmek yerine daha yoğun alanda gitmeyi tercih ediyor cisimler bu şekilde izah edersek yoğun alanda daha hızlı gitmeli olanda bu. Uzay standart kuvvet uyguluyor cisimlere yoğunlaştığındada bu kuvvet artıyor.
In my opinion one of the most important moments of this video is at 0:40 when the sheet is turned upside down, and the paths do not change. The classical rubber sheet analogy in explaining gravity is easily misunderstood. Balls rolling on a rubber sheet do not follow actual geodesics, because they are affected by gravity. On the other hand, real geodesics are purely geometrical and there are no forces involved.
@@EugeneKhutoryansky Thanks for the hint! Coincidentally I have not had opportunity to watch this video to the very end. Anyways, thanks for your great work, this is absolutely brilliant!
Straight line: the geodesic which lies on a flat plane. Straight line time: The measurement of the motion of an object or entity along this straight line. Cyclical time: time which measures motion along the surface of a discrete object.
Is there an easier way to find a geodesic on a sphere? Place two points anywhere on a sphere. Using these any-two points you can define a great circle. Useing this great circle, define a cross-section. Viewing this cross-section you will see the two points between which you can trace a curve (following the outer edge of the sphere). And using the length of a curve formula you will determine the shortest distance and straightest path between these two points. No need for a metric tensor or Christoffel symbols. Thoughts?
All the music in this video is from the free RUclips audio library, and the names of the songs are the following. Wigs Clouds Wedding_Invitation Road_to_Moscow
If the two points are right next to each other, then the geodesic connecting them is the shortest path. But, if the two points are far away from each other, not every geodesic is the shortest path.

"Gravitational Time Dilation casues Gravitational Attraction."
Is it one causes the other, or is there some sort of duality?
Former is a fundamental fact. Latter is its consequence, and basically an "illusion".
Gravitational time dilation tells you that distant frames in a gravitational field will begin to appear to move relative to you (they will accelerate relative to you) because rather than moving entirely in the time direction through spacetime, they will lose some of their 4-velocity in the time direction, relative to you, and transfer that 4-velocity to a spatial direction, this all appearing to you as a gravitational force pulling these object through space, and slowing them down in time.

Your videos are so calming. The music fits perfectly with the amazing animations. And your voice is also calming. You'd think that would make the videos less interesting, but it really doesn't. It makes them a good way to get in a good mood while learning about math and physics.
When talking about General Relativity with people I've explained that the curved time component is what explains gravity. Everyone thinks I'm the crazy one LOL. Thanks for making this video, it's such a great explanation. Understand concept first, then it's pretty easy to grasp what the math is doing because it's no longer abstract!
Thanks.
I find this absolutely fascinating.
May God give you what we humans cannot compensate. Beautiful video as always.
Thanks.
I do like these videos, but personally I think they'd be better with a bit less 'down time' and, relevant to this video, not repeating the same sentences, I feel if someone doesn't understanding something there's always the rewind button, but if you skip forward you might miss something. Thankyou for making these videos though! They really do help make more tricky concepts easier to grasp!
6:20 i believe it's a good model of the event horizon, the light that managed to escape from the gravity, and also the light that was kept inside the black hole.
Very beautiful video.

Huninin şeklini tepe noktası kütle merkezi olarak düşününce kütle çekiminin nasıl çalıştığı hakkında gayet net bilgi veriyor.Huninin tepe noktasına doğru hareket için gerekli alan azalmıyor çoğalıyor normal alanda gitmek yerine daha yoğun alanda gitmeyi tercih ediyor cisimler bu şekilde izah edersek yoğun alanda daha hızlı gitmeli olanda bu. Uzay standart kuvvet uyguluyor cisimlere yoğunlaştığındada bu kuvvet artıyor.
This is more than a beauty
Thanks.
2:25 that is really trippy
This vedeo is interesting. When we consider the notion of focal points, we alwarys use the sphere, but in this vedeo, we can see various focal points.
Very happy I subscribed!
I am happy you subscribed too.
In my opinion one of the most important moments of this video is at 0:40 when the sheet is turned upside down, and the paths do not change. The classical rubber sheet analogy in explaining gravity is easily misunderstood. Balls rolling on a rubber sheet do not follow actual geodesics, because they are affected by gravity. On the other hand, real geodesics are purely geometrical and there are no forces involved.
And the rubber sheet analogy of gravity is also bad for many other reasons too, as I describe in my other video that I reference at the end.
@@EugeneKhutoryansky Thanks for the hint! Coincidentally I have not had opportunity to watch this video to the very end. Anyways, thanks for your great work, this is absolutely brilliant!
If Eugene Khuturyansky doesn't get a Nobel for video creation and visualization, then they don't know what it all means.
Thanks.
Eugene thank you for another wonderful and informative vid. Boy how I wish you were around with these vids back when I was in high school!
Thanks.
Straight line: the geodesic which lies on a flat plane.
Straight line time: The measurement of the motion of an object or entity along this straight line.
Cyclical time: time which measures motion along the surface of a discrete object.
Is there an easier way to find a geodesic on a sphere?
Place two points anywhere on a sphere.
Using these any-two points you can define a great circle.
Useing this great circle, define a cross-section.
Viewing this cross-section you will see the two points between which you can trace a curve (following the outer edge of the sphere).
And using the length of a curve formula you will determine the shortest distance and straightest path between these two points.
No need for a metric tensor or Christoffel symbols.
Thoughts?
Awesome video! Thank you!
I am glad you liked my video. Thanks.
Absolutely amazing. Thanks for your hard work on this channel!!
Thanks.
These videos need more SLAYER, then they would perfect! ☺️
This is Gold Mine
Thanks.
at 4:30 what music is that
i would very much appreciate if the music were listed in the description :)
All the music in this video is from the free RUclips audio library, and the names of the songs are the following.
Wigs
Clouds
Wedding_Invitation
Road_to_Moscow
@@EugeneKhutoryansky it is such nice music
Great video. I have a question 2:31. Aren't geodesics by definition the curves with the shortest path between two points?
No. They are the shortest paths between two points only if the two points are right next to each other.
And thanks for the compliment about my video.
Is the geodeci the shortest path between two points, contradicting what you said around 2:40?
If the two points are right next to each other, then the geodesic connecting them is the shortest path. But, if the two points are far away from each other, not every geodesic is the shortest path.
This is why this guy is the best
Thanks.
Amazing animation
I have no words to appreciate uh
Thanks for the video
Thanks for the compliments.
