Some answers to the questions I have been asked: - Has this visualization not already been presented? No I don't think so : you may have already seen a visualization with a distorted 3D grid (like at 5:20), but the crucial point that distinguishes my new representation is its temporal dimension. It is the fact that the grid is perpetually contracting which allows us to better understand the way bodies fall (and which is more faithful to the equations). As far as I am aware this has never been represented in this way, surely because this is only possible with the video format. EDIT: I have since then discovered that this visualization does exist, at least a similar one called the "river model". It allows for an intuitive understanding of black holes for instance. - If space contracts, shouldn't there be an accumulation of space in the center? Beware no, it is not space which contracts : it is only the straight lines (geodesics) which get closer to each other due to the curvature of spacetime. In the same way that on the sphere the geometry does not change (see at 9:10) , the geometry of space-time is static, it does not vary. But this geometry gives a tendency for straight lines to come closer to the center - How to define a temporal speed? In relativity there are two different times: the time of the observer (the coordinate time / the time dimension), and the time of the object (proper time). Velocity in relativity is the derivative of the coordinates with respect to the proper time of the object. The "temporal speed" is therefore simply given by the rate at which the time of the observer passes compared to the proper time of the object. To find out more, check out my series about the Maths of General Relativity

The only struggle I had was with the perpetually contracting grid “bunching up” an infinite amount of spacetime at the center of the earth. I’ve understood gravity to be the effect of time dilation with a slower running clock at the base of the Apple than the top. So if the perpetually contracting grid was representative of time - inertial frames of time constantly traveling the geodesic to the center of the earth then it works for me flawlessly

this is a very nice explanation but we are dismissing one an important thing. There is no evidence of the curvature of galactic space and time but mathematical computes. And by the way, elastic sheet does not as same as space fabric in effect galactic empty space. The marbels onto elastic sheet are attracked to the center with bigger ball. Unlike planets such as Mercury, Venus and Earth that orbit around the Sun but are not attracked to it. It is the huge difference that suggests elastic sheet doesn't prove anything. Regard!

The feeling of it clicking when you mentioned that even if the apple is sitting still in space, it's still moving at a velocity through time was crazy.

This gets amplified in black holes where time kind of swaps with a spacial dimension so hard making the center of the black hole a direction in time (once you pass the event horizon), it becomes the future. It’s weird but it’s like in weak gravity you can escape the tendency of the future by spatially moving away from the planet for example, while inside an event horizon, no spatial movement can make you go back in time, time is pushing you closer.

Awesome work! A few years ago i had a similar idea but as i had no skills with video-production and the graphical tools needed for a job like this i never bothered to even try doing anything with my inner picture of this stuff. :P Since that moment i have been speculating on and of how the "flow of spacetime" influence the outer regions of spiral galaxy's in regard to the "Galaxy rotation curve problem". I feel fairly certain that Kepler's laws don't take into consideration the accumulating flow of spacetime inwards in the spiral arms direction and that this allows the higher rotational speed without the predicted "side effects" of solarsystems coming unbound and slingshot out into deep space.

This is by far the best intuitive explanation of how the perceived "force of gravity" actually works! I've seen dozens of videos, and they all stop several steps short of a useful explanation -- but in this one, the beautiful visualization of movement through time makes all the difference, and IMO gets one as close as possible (realistically) to getting some semblance of an actual grasp of how "free-falling"/inertial objects behave in spacetime.

Great way to touch on Special Relativity too - "c" is not the speed of light, but instead is the "c"onversion factor between meters and seconds. One thing I always liked to demonstrate the 4-dimensionality of spacetime is a thought experiment: If you describe the motion of an apple with a 3-dimensional vector (up/down, left/right and forward/back), then when it's at relative rest, the direction of that vector is undefined. Stopping an object shouldn't break the math behind physics, nor should it leave us with a hidden direction variable - so something else has to be going on. Adding a fourth dimension means that when at rest in 3-space, the object is at maximum speed in the fourth dimension - time. Speeding up in one of the other 3 space dimensions necessarily means slowing down in the time direction, and you no longer need to use the magnitude of the vector to describe speed, it can be used for energy instead - plus the orthogonal space directions to the object's own time direction are no longer tied to the observer's space directions, so even time rate and dimensional length can change with the object's relative speed - therefore you get all the effects of Special Relativity for free.

You know, I feel as though my understanding of relativity has been hampered by the "balls on a sheet" representation. I've been learning about relativity since I was basically a kid, and was eventually able to gather a decent understanding of the math behind it, but the warping of spacetime never made intuitive sense to be because through the entire process everyone was saying to imagine it like balls on a sheet (even legitimate academic textbooks). But finally after seeing this, I get what the math has been trying to tell me all this time. It's so simple and elegant. It's a travesty that relativity isn't taught this way.

How can I then understand the concept if he doesn't make certain I understand the definition of a word? THIS IS WHY EGGHEADS CANNOT BE GOOD TEACHERS. They can teach people with a preexisting knowledge of the subject, but not to someone like me. I so want to understand special relativity, but there is no one to explain it to a neophyte.

not sure I still fully understand it. I might have to rewatch it. Kinda reminds me of fluid dynamics with a ball whose mass is being displaced underwater. If you were to pop the ball so to speak would gravity behave similarly to water in that it would rush back into itself or does it have a finite speed like light? My guess is gravity has no speed since spacetime itself is what is being altered not the distance within it.

I always kept wondering where the 4th dimension (time) would get placed on the 3D graph lol. After watching this video I think I understand the space time curvature much better than before. I personally think it's the most appealing way to describe the theory of relativity and the space time fabric in an animated video.

Thank you so much for this video! Every time I saw those typical visualizations and demonstrations that you show in the beginning of the video, it always made me wonder why the moon doesn't crash into the earth, why the earth doesn't crash into the sun, and so forth. Now I FINALLY understand that the earth doesn't actually orbit the sun, the earth is just travelling on a straight trajectory and because of conservation of momentum, no forces acting on the earth, and spacetime being distorted by the mass of the sun, it just APPEARS as if the earth is orbiting the sun. The earth is just travelling in a straight line; wow, I can't express how profound it feels to me to FINALLY understand this!

@Muckin 4on Ah but nothing is actually contracting - It’s the geometry of time that is being affected by a massive body. If you sat on a chair for 3 days and didn’t move, you are actually still moving through time in a given direction, it’s just that we don’t perceive this as a motion. If I then stick a massive body by you, the direction of this motion will curve towards it as the direction of this time’s journey has been influenced by a change in the geometry of the space in which it’s travelling. The model showing perpetual contraction is just a way of showing how every object is making a journey through time in a given direction.

I can tell you precisely: Socialism is when things are ruled in the interest of the people. Capitalism is when things are competed over and denied, excluded from the people. For Karl Marx, these things are narrowly economical, but he researched it a long time ago. For our leaders and media, Socialism is the stereotype of Soviet model, which was corrupted by Capitalist leaders and laws, although it began with the interest of the people in mind. Stalin was a Capitalist not in the sense of Free Market and Central Planning but by socio-political outlook. Authoritarianism, Dictatorship, Totalitarianism are mistaken as Socialism and Communism is mistaken as the outcome of lack of Democracy. Democracy is mistaken as the flawed election system, where power and decisions are not discussed by people in person, but by Capitalist leaders and laws. Capitalism is mistaken as Free market, freedom and Democracy, because it is depicted against the context of Totalitarianism, Central planning and not American economy, which used to be expansive at the time. Therefore Central Planning and Free Market is just a practical question and has nothing to do with Left or Right. In the end, the Anglo-Saxon Capitalism was the narrative of only the rich. Capitalism is every way of anti-social behavior, because it excludes the Other, even if it gives Freedom and wealth, and even the fair Soviet welfare. Democracy really should have everybody in the discussion. Socialism doesn´t really exist in the welfare programs of center-left parties as it was Marx´s word for the worker´s control of the means of the production and it must be rewritten to mean the Ideology of moving away from all Capitalist leaders and laws. Communism was Marx´s possible outcome for having the means of production in the hands of the industrial workers. The poltiical left is defined as "Equality in expense of Freedom or Security" and political right is defined as "Freedom of Security in expense of Equality". That is why Socialism really is only Libertarian Left,, not Authoritarian, and Capitalism is Authoritarian Right, because it cares about Freedom to enterprise or from other people´s competing influences. Neoliberalism is Libertarian Right, which fantasizes about the ultimate Free Market as the source of Equality, Freedom and Security. Right can never ever actually be free or secure without Socialism. Therefore Equality and Libertarianism precede the Right Ideologies and are prerequisites of Freedom and Security.

@RichardWilkin
@RichardWilkin 3 жыл бұрын
But speed always involves both space and time: speed = distance/time. So it doesn't make sense to say "temporal speed" or "spatial speed". Speed (or movement) is always both temporal and spatial.

@ScienceClicEN 3 жыл бұрын
In relativity you can also define a distance in time (time is a dimension just like the 3 dimensions of space). The "speed" is calculated with respect to the proper time of the object, while the "distance in time" is calculated with the time of the observer (it's a coordinate)

Both speeds are measured with respect to proper time. Spatial speed is the change in the spatial coordinate as proper time goes by, and temporal speed is the change in the time coordinate (the time measured by the observer) as proper time goes by

Thank you for a very effective “visualization.” The beauty of nature is that it has no obligation to make itself understandable to any one intelligent animal using any one of their limited senses. A critical nod to the importance of role of the observer. Einstein, and any observer who can rise above their known limits, understands that we can’t actually “visualize “ what is going on! Artificial senses like mathematics and physics are tools that give us a tiny glimpse into these miracles by creating a junction between the reality and our wiring. Meanwhile, the average conscious human, and rabbits, etc, think nothing of it because it can’t be observed by their given senses. The apple falls………. And we just eat it.

All of the previous models never made sense and cause me to have more questions than to actually understand how any of this worked.. Now I do and I do clearly. this should replace all other animations or representations shown today. Thank you for finally making this model. I cannot believe we ever tried the marbles on a sheet example now that I see this.. How in the world did it take so long for anyone to make this version. This is crystal clear and perfectly explains gravity and answers all questions and doubt created by previous illustrations. Thank you for this!!
