During the recent period, I've reached a point where I have a good order in my head (previously, there was a relative disorder prevailing for a considerable period of my life, which I expect to be clarified soon), and thus, I can much more easily "visualize" potential scenarios for the world around us. I've now organized my thoughts and express them in words that are much more carefully structured in my sentences. So perhaps I can manage to convey to you what I have in my mind, and they make exactly the sense I want.
In the previous text, I revealed the possible existence of extra dimensions. Specifically, if we absolutely want to justify the existence of gravity, the theory of superstrings probably covers us. I remind you that gravity is the (hypothetical for now) particle responsible for gravitational attraction. The existing theory suggests that a particle is exchanged between bodies, causing this attraction. (Increasingly, this seems to me an incredibly childish notion, as spacetime curvature suffices, I believe, and does not require the existence of this particle. We've said that perhaps time is the only responsible one...)
The first part, which is probably easier to imagine (as much as anyone can), is the extradimensions. An easy example follows:
In Video 1, we have Piu, who is a kid sitting in his world. Piu's world is different from ours. As you can see, it only has 2 spatial dimensions and of course, time passing, so Piu's universe is three-dimensional, and the Doppler phenomenon might not even apply there (there's no scientific reason for this, it's just a fan element of the universe 3, as I'll call it 😝). So, Piu, no matter how hard he tries, will never see/find the third spatial dimension. Why? Because he doesn't have the sensory organs to understand/perceive it. His eyes, his brain, his body are designed to perceive only 2 spatial dimensions.
What will happen if a being from our "level" intervenes in Piu's level? Based on the video, hungry Piu in the desert, while wandering for years, began to find food that suddenly fell in front of him from the sky... What does that remind you of? Maybe some tough times are coming, I probably booked a spot in hell, which ultimately seems to be frozen rather than hot (that's another matter 😅). Nevertheless, with this example, I think you understand that already in our universe, we are the beings that understand more dimensions than some other entities, and there's a "universe" of fewer dimensions, Piu's universe.

I think we got the gist of possible extradimensions, which no matter how hard we search, we're probably naturally unable to see while they might exist everywhere around us like webs from a cosmic Shelob (a spider from a well-known epic trilogy...).
The next possibility is that dimensions are very small and perhaps folded, one within another and within itself. Could this folding be responsible for the points where later gravitational centers appear in celestial bodies? I wonder and hope to find the solution.
In the next video, I'll show you an example of folding which I'll describe to you in words immediately. How do I imagine the folding: suppose we have an extra dimension that could be a plane and suppose that some particles have certain characteristics which we either ignore because we observe them differently, through physics so far, while these particles are trapped to move on that extra dimension. So, if this dimension is folded upon itself and instead of being a plane it has become a cylinder of very small dimensions, in the macrocosm from which we make the observation, we wouldn't perceive it. Imagine a particle moving on that dimension at the speed of light, as it moves on this dimension it would be trapped to make a helical motion around an imaginary stick that has been created. So if this particle moves at the speed of light or even faster, due to the helical motion around the stick, we would observe it moving at a slower speed than the true speed with which it moves. And this would happen because in the dimensions we perceive it would cover in a specific time a specific space, but the particle itself would have covered, due to its helical motion, (probably) a much larger distance than the one observed. This would give us the illusion that the particle moves at a slower speed and that this is the result of the possible mass it has and because of gravity it decelerates during its motion or otherwise slows down under the influence of gravitational forces on its mass. So we would observe it and thus explain it and possibly do so for decades now. So it is very likely that there are extra dimensions which are also very small and folded in various ways, apart from the stick I've thought of, which with classical theory and with the observation we can make based on our technology may lead us to wrong conclusions, that some particles have mass or cannot move at the speed of light, while in reality nothing of the two might happen.

The universe may hide several secrets which we think we know and believe we know what happens and why it happens, but we may need to gradually be led to a review and reconsideration and perhaps change of science itself.
As our ancient ancestors used to say, "everything flows." Nothing remains unchanged, everything changes, energy changes forms, matter itself, so why shouldn't the perspective we have for the universe and the world around us change as well.
