Hi sir. You are requested to make a video on this: 1. When does the sun's magnetic polarity get reversed? 2. What impact will it have on the Earth? 3. Recently in 2020, the sun's polarity has been reversed, for the 25th cycle. When was the first cycle occurred? 4. Approximately when will the 48th (final) cycle occur? 5. What will happen, when the final 48th cycke occurs? 6. Whenever the first cycle had occurred, before that had no polarity reversal cycle ever occured on the sun? 7. Will the sun never ever change its polarity, after the 48th (final) cycle? 8. If the answer to question 7 is that the polarity will stilll be changed even after that, then why is the 48th cycle considered as the final cycle? 9. If after the 48th cycle, any new fresh cycle starts, then what will be different in the cycle? Why will be a fresh new cycle and not the 49th cycle?

This is the first time I have seen gravity caused by time. Every other text book, article I have read has said mass bends space-time. LIGO measured changes in distance. I’ve even seen gravity bends time. Descriptions of general relativity, The rubber sheet analogy and the resultant term “gravity well” alludes to space gradient being the significant component of perceived gravity, not the time gradient. If it’s true that it’s time, why is it not so widely taught as such?
@EugeneKhutoryansky

Tanner, the text books are correct when they say that mass bends space-time. However, the rubber sheet analogy is not accurate because it does not show the "time" component of "space-time." The curvature of space components relative to each other become very relevant when moving at relative velocities close to the speed of light, or when near a black hole. But for the type of situations which we normally encounter, where Newtonian physics is an accurate approximation, it is the curvature of the time dimension, relative to the spatial dimensions, which is the most important effect.

@@EugeneKhutoryansky I understand the analogy isnt perfect, hence it is an analogy and as stated it bends space-time. However you are stating that the time component is the most critical component? Is there a specific formula for this (I could not find within the special relativity formulas)? The way i understood it was newtonian physics only explains so much light curvature around a massive object as it only takes into account bending for space (for arguments sake lets say half the predicted outcome) whereas the Eddington experiment proved general relativity of bending space & time (the other half). Is it not 50/50 is it 80/20 or some other mathematical relationship?

I had a hunch they were not complete, how could they be, but because I was never given what was missing it was hard to see what I was getting wrong when I tried to actually use the metaphor as a mental starting point to understand.

No, gravity is a result of the curvature of spacetime. You are confusing the apparent gravitational attraction caused by time dilation, which can also be caused by an accelerated reference frame, with actual gravitational attraction, which is only caused by the curvature of spacetime. To further understand the distinction between apparent gravitational attraction caused by time dilation and actual gravitational attraction due to spacetime curvature, consider the example of a rotating spacecraft. Imagine a large cylindrical spacecraft rotating about its axis. Within the spacecraft, there are astronauts standing near the inner surface. As the spacecraft rotates, the astronauts experience a sensation of weight, as if they are being pulled towards the inner surface. This apparent gravitational force experienced by the astronauts is not solely a result of centrifugal effects, but also arises from a combination of centrifugal effects and time dilation. When the spacecraft rotates, the centripetal force pushes the astronauts towards the inner surface, giving them a feeling of weight or apparent gravity. This is similar to how an object on a rotating carousel is pushed towards the outer edge due to the centrifugal force. However, it's important to note that this apparent gravitational force induced by the spacecraft's rotation is not caused by the curvature of spacetime. It is an effect of the centrifugal force and the resulting sensation of weight experienced by the astronauts. In contrast, actual gravitational attraction, as explained by general relativity, arises from the curvature of spacetime caused by mass or energy. It is the warping of spacetime itself that influences how objects move in a gravitational field. Therefore, while time dilation can create an apparent gravitational attraction, such as the experience in a rotating spacecraft, it is distinct from the actual gravitational attraction caused by the curvature of spacetime. Time dilation occurs due to relativistic effects like differences in motion or strong gravitational fields, while actual gravitational attraction is a result of the curvature of spacetime caused by mass or energy.

In your apparent gravitational force's example, you added 'motion' What Eugene described is the phenomenon which will occur if there is no motion in the dimensions of space. For example if a body is not moving at all, it is still evolving in time dimension and the speed at which it is evolving through time will cause an acceleration which will cause the gravity. What gets proved from this example is that if a body is not moving, it will still have weight and will attract other objects according to the intensity of its field of influence. I hope you will understand. English isn't my primary language so don't mind my bad grammar.@@skhotzim_bacon

Man, thank you for this. I feel like I almost have it visualized. Like I can almost make out the silhouette of the concept through the fog before it fades again. I think what's messing me up is the apparent rotation of the barbell object in the video It makes it seem like it would have to rotate spatially as it moves toward earth, but I know in reality it doesn't. I'm trying to picture how, say, a ball or point object would be made to freefall by time dilation, or how an object at rest on a surface of a planet is kept there by time dilation, and how that relates to the perceived acceleration upward by the surface. All I can picture is a stationary object at the same distance from the earth just aging differently, I can't see how it initiates the movement from that graph.

Awesome description - without all the mind boggling maths! Would I be correct then, that an object's motion through time, (when there is a 'time gradient' in spacetime, caused by its proximity to a mass such as the Earth) causes the object's motion through the time dimension of spacetime, to translate into a motion through the space dimension of spacetime? If so, what is the 'mechanism' by which an object's motion through time becomes translated via this time gradient surrounding a mass such as the Earth, into an object's movement through space?

@Baker's Bread I feel like it would be less of a flipping and more of a stretching... the body may be rigid in the x or y axes, but the difference in rates of motion along the time axis could very well be constant, and so the stretch-i.e. difference between positions of the body through the time dimension-would be as stretchy as you want. Like you recognized in your first reply, zero effect on the position of any parts of the body, since motion along the time axis is completely independent & orthogonal to the x & y. 2D spatial position would be given by a projection or shadow of the object straight down along time axis onto the xy plane. Since time has no effect on the position, it also does not strictly cause a rotation in this presentation, since rotation would imply motion in xy of the projection or shadow. But I agree-I can’t see how this time dilation causes attraction...

Glad to see someone finally do something other than the indented sheet visualization. I had to imagine gravity pulling things into the sheet so the visualization was useless. I didn't realize what was going on until I managed to figure out that everything goes through space-time at a constant speed of causality. So if you are not moving through space, you must be moving through time. And if you are moving through space at the speed of causality, time is stopped for you relative to observers. This type of visualization would have helped me figure that out a lot sooner.

Eugene, I always understood that the warping of spacetime simply caused the spatial vector we know as 'down' to point slightly towards the future and that inertia prevents objects with mass from instantly reaching the speed of light. The force of the ground against an object is acting slightly against the flow of time and thus causes a continuous divergence from the inertial reference, slowing time's apparent progression. Is this incorrect, or is the explanation in your video logically equivalent (i.e. indistinguishable from a physics perspective) from my interpretation?

Great story! I've been reading, seeing this a lot lately; "gravity is not a force". It reminds me of an analogy explaining why light refracts: imagine several columns of soldiers marching towards a river, at an angle. One column is going to encounter the river mud first. They'll be forced to slow down. The other columns haven't got there yet, so they don't slow down. From a top view the soldiers looked like a straight line, until they hit the river banks. It looks like a bend in the line, just like refraction. When they get to the other side, the opposite happens. Then it looks like the line bends back. Again, just like in refraction. It's funny that high school refraction lessons could be the key to understanding how gravity works!

You considered an accelerating elevator and you explained that the time interval between two pulses will be different at ceiling and floor because of time dilation. Suppose a theory is developed, which says the time interval is different because the light pulses are accelerated relative to this frame. Will it violate principle of equivalence or the postulates of special theory of relativity?

The gravity of a different object will interact with the the first object & the sum of the numbers will influence the course of the objects. If the >milky< way gives you starry sk-eys ? Then our earth churns out to be a weight on your mind :-D

The object does strech but up to a point because it will resist the streching (or break apart) Given that the forces have different magnitude, it will not just move in a straigh line but also rotate, resulting in a curved path

There is another spatial 'direction', or 'dimension' if you will, that is not yet recognized and incorporated as such by "the standard model". As convenience would have it, this turns out to be the 'direction' in which a spherical shock wave 'expands' - and an 'imploding' one 'collapses'. i.e. there is a '4th direction' in which momentum can be transferred "through-space-over-time". Note that if this "point-radial" (PR) direction has real physical significance, as described here, then the architectural feature of the actual (yes, non-Euclidean/non-linear) geometry of "space-time" is in fact the basis for the apparently "particle-based" architecture of the "material universe" - it is the "point-singularity" at the center of the 'horn torus' - i.e. the horn-toroidal "fluid vortex" in the physical counterpart of theoretically convenient "ideal fluid", which is, of course the SUM (scale-uniform 'super-(or 'hyper'-)fluid' medium), traditionally known (in its 'stationary' - i.e. not PR'ly acceleration-flowing - state) as "empty space"; and later "identified" by A. Einstein as "space-time". And note also that if this 'PR-dimensionality' is so, then a human being's entire "experience" of A.E.'s "space-time" universe could be 'manifested' - some might say "simulated", as in "generated by a 'simulator' software program running on a computer" - as the "standing waveform" interaction/interface between an individual 'outwardly expanding' momentum(or "acceleration")-pulse wave-front and a series of multiple "in-coming" (i.e. "PR''ly collapsing") momentum-"pulse" wavefronts... Note that (as the convenience of serendipity, and old Occom himself, would have it) the spherical shape of an expanding shock-wave in an ideal fluid is identical to what we are "intuitively" comfortable with as the shape of a "particle'". ... And as convenience would have it once again, the PR 'direction' is also the (some might even say "seemingly providentially") apt candidate for description of the ever-changing 'PR'ly expanding' wavefronts we call "particulate (as in "particle-based") mass-objects" (PMO's) as "time passes". ...

Hey Eugene, I deeply admire your work and been following you since a decade. I have a question, hope you help me understand this better: I have heard this same explanation at several places as to why objects fall in gravity. Now, in that object, the point that's farthest from the earth will move faster than the point that's closest to the earth. That would make the object tilt. However, it does not explain why the point closest to the earth will move towards the earth at the same time. Can you please help me understand this please?

The point farthest from the Earth will move faster "through time." Therefore, when we say the object is "tilting" that is the same thing as saying that it is moving towards the Earth, since it is the direction of the time dimension that is tilting, and the object moves forward in time.

As there is no force on the object, will the object follow a curved path in xy or will it simply be a straight (to earth) line from a spatial point of view?

Great video as always. And I'd like to say that PBS Space Time has done an excellent video on this as well. However, I'd like to point out that instead of straight lines, you should have said geodesics because the objects follow geodesics through the curved spacetime and they aren't always straight lines.

The ‘tilting’ of the object due the different parts moving at different rates through time reminds me of how the refraction of light is explained by wavefronts moving at different speeds through space . Is there a connection?

Excelente video. Existe una forma mas intuitiva y rigurosa de visualizar la atracción gravitacional por dilatación temporal: -1 Representar el tiempo en la linea de tiempo del propio video. -2 En el eje z representar la "velocidad" a la que transcurre el tiempo, con valores desde cero (tiempo detenido) a 1 (velocidad 1segundo x segundo) -3 En los ejes X e Y representar dos dimensiones espaciales.

Wait, so, at 2:40, wouldn't you just get a cross-section of the object at any given value for time? The 3D visuals for the object in 2 spacial and 1 temporal dimensions is also confusing: the argument breaks down entirely when you use a 2D render of the object instead. Also, what compels you to reason that the object would necessarily experience a torque? There is no force holding the object in the temporal dimension, so, wouldn't it just stretch? ALSO, what about the fact that massive objects curve space time, resulting in the rising of the Earth at 9.8 ms^-2 upwards while the object is inertial in spacetime? Isn't that the very first thing we learn about General Relativity, and isn't that line of reasoning much simpler? Would greatly appreciate it if you clarify these questions.

Hey guys, interesting video, but why can't the objects simply stretch into the time dimension? The further away part could simply get older faster than the close parts, what constraints this stretch into the time dimension and therefore induces the rotation?

As stated in the video, this is an imperfect analogy, since a point particle with zero volume will still follow the same path. The issue is not that the particle is "rotating" but that a straight line in curved space-time follows this path. A straight line on a curved surface is called a geodesic. Perhaps the following video on geodesics would be helpful. kzitem.info/news/bejne/r5yn2Heaepyanqg

I'm confused, some people say we go down because time is curved towards the ground, and we travel in time. Others say because time is different at my head and my feet and creates a torque to go to the slowest time, which one is it?

At 2:16 you say that the object move through time and different parts or the object will move through time at different rates, but you show the object moving through SPACE , so i don’t understand how the movement through time causing the attraction. I completely understand the movement through time, but doesn’t it just mean the object will be standing still as different parts of it move through time at different rates? How does the object move in the first place? It had anything to do with slower object appear heavier or something like that?

I really like the video. Thank you for posting it. I am still hesitant @ 2:58. Though it initially seemed obvious, why would the object move closer to the Earth, versus farther away? In the time dimension each end of the dumbbell is moving at a different rate, so in the middle is a sort of fulcrum around which it begins to rotate. But why does that middle point not stay stationary in space, and the closer end not move away from the Earth as the farther end moves closer? Is the above concept of a middle point of rotation accurate? Or is the situation rather that the point nearest to the Earth remains that close and no closer, and that closest point itself becomes the axis of rotation? So that the other end definitely moves closer to Earth until the dumbbell is perfectly vertical and parallel to the cylinder that is the Earth as it moves through time? At that point the outer side of the dumbbell is moving more quickly through time, but as there is no more shape-caused easily conceived point of rotation, I'm not sure what happens. However, in this second way of understanding the situation, the object overall has moved closer to the Earth, even though it's initial closest point is still exactly the same distance away. Anyway, this isn't me resisting the concepts or any other part of the video, just wrestling to understand versus merely taking the video's assertions without understanding them. Thanks again.

I have the same question, the dumbbel shapped thing rotated left and travels towards the earth, but why doesn't the dumbbel shapped thing just rotate around it's center of mass and continue to move upward without approaching to the earth? And if the object is a point , it seems to just spin on itself and will not travel toward earth. Although he or she had already said at 3:05, this visualization does not accurately represent the full picture, since a point

I also found this aspect of the explanation troubling, whether that's on me or the video. My understanding is that objects would have to be incredibly large or be near am incredibly large body to have any sort of significant "time gradient" within itself. And the fact that point particles follow gravity as well in the absence of such a gradient across their volume makes me a bit sketchy on the value of this explanation

Hi I see you responding to newer comments which I really appreciate. I’ve been so fascinated by space and physics recently but now starting to get confused at all the different things being said and disagreed on in the study. I saw your comment on Dialect’s video on the “true cause of gravity” video. Someone here is wrong and don’t know what to believe.

No, as I mentioned in the video, even a particle with zero volume would still follow the exact same path. The effects of gravity do not depend on the volume of the particle. Therefore, this is an imperfect analogy.

XY plane shrinks as the bar goes upward in time, and that's why the bar "moves" toward the Earth. Points closer to Earth experience stronger shift than the further ones, btw the latter travel faster in time and thus experience more shift to Earth than you could expect. Actually, since space shrinks not so much, it's time dilation who contributes more to the bar shift. With only time dilation the bar wouldn't move toward Earth, but it would just age at different speeds at the two ends (any worldline slice with same-age bar points would stretch moving upward in time, but each slice for a given instant would be of the same lenght, connecting bar points of different ages). Does it sound better?
