Right, that's why I propose the hyper sphere geometry. Our universe (the part we can perceive) would be the surface of the hyper sphere and the mass of dark matter would be located in the center of the hypersphere. Each body of matter in our universe would be equally distant from the center of the hyper sphere. A hand-wave is sadly the farthest I can go 😅

How would it cancel? The apparent attraction to each other would be explained by the spacetime curvature around each body of matter. This is the very start of the thought process and I wouldn't be able to express it mathematically. It's hazy, fuzzy, vague but it may have some truth in it. That's why I need the right physicist to take a look at it. I find it a bit frustrating that the brightest minds in the world haven't cracked the problem of the nature of gravity yet, despite being the first force to be acknowledged scientifically. Maybe a change of perspective is needed. I want my interstellar travel and I want it now ! 🤣😆

Possibly the dark matter that permeates the whole universe.

Thanks for your reply MigL. I'm glad you catched the analogy, that's pretty slick actually. I acknowledge that I might have stretched the rubber sheet analogy way too thin 😁. Maybe the only significant part of my (rudimentary) conjecture is the idea of gravity (between masses of normal matter) as a fictitious force. Gravity looks like an attractive force between bodies of matter, it feels like a force between those bodies and even computes as such, but maybe it's an "illusory" interaction. If this conjecture is good, it would have to be compatible with relativity theory, or at least compatible with a modified relativity. The black hole simulations offered by relativity would still be valid and there wouldn't be any reason to start a new simulation from scratch. I used the "exotic" term loosely, it means that we have no idea about the nature of such matter. I don't expect my conjecture to be 100% true, that would be impossible with my limited knowledge. It occurs to me that the the brightest minds in the field are not lacking any intelligence to solve the gravity conundrum ; maybe they just need a change of perspective... maybe the perspective of a naive outsider. My hypothesis wouldn't contradict the Cavendish experiment at all. It states that the measured forces between the lead balls don't come from any interaction between them. The particular geometry of our universe just makes us believe that there's a force between the lead balls. The actual force would be produced by the gravitational interaction between matter and the hypothetical body of "exotic" matter.

Sorry swasont, I tried to reply to your last question but I missed something. This is the answer ⬆️⬆️⬆️⬆️

In this scenario, it's assumed that all the observable matter in the universe (as of today) is composed of 100% normal matter. The exotic matter is hypothetical and would be very difficult to observe (like dark matter) and even more difficult to produce. You could be 100% certain that the rock is made entirely of normal matter. All the exotic matter in the universe would be condensed into one single body. There wouldn't be any exotic matter intermingled with normal matter. The hypothetical exotic matter might be the same as dark matter.

Exotic matter would behave more or less like dark matter and all the exotic matter in the universe would be condensed into one single body made of 100% exotic matter. There wouldn't be any exotic matter in bodies composed of normal matter. Exotic matter might be produced in high-energy particle accelerators but could be extremely unstable.

Thanks for your reply swansont. The exotic matter would be something like dark matter. Gravitational interaction would occur only between normal matter and exotic matter.

Hello, I got the following idea from the observartion of a gravity well, like this one: https://youtu.be/mgZ84NAW0zU I'd like to know the opinion of a physicist about this. This is a naive, crazy, intuitive, outrageous new perspective on gravity and possibly quantum gravity. It's an out-of-the-box thinking experiment. It's the kind of thing that may be overlooked by highly specialized scientists. Please, go past the first assertion. Is this thing even mathematically viable? Here it goes: 1.There's no such thing as a gravitational interaction between masses composed of "normal" matter . Rather, each mass composed of normal matter in our universe interacts gravitationally with a hypothetical, single, huge mass of "exotic" matter. Dark matter, maybe? 2. The gravitational interaction between masses of normal matter and the single, hypothetical big mass of exotic matter would produce the well known spacetime curvature around each mass of normal matter. Small masses of normal matter would get caught in the spacetime curvature of big masses of normal matter. At first sight, It would look like the small masses are being attracted to the big masses, just like the small balls of the gravity well appear to be attracted to the big ball. 3.Such modified gravity might be mediated by a particle (the actual graviton, maybe? ) that might be produced by normal matter, but would interact with exotic matter only. It would be then impossible to detect gravitons with normal matter. In this scenario, a device housing a sample of exotic matter may be needed for detecting gravitons. 4.In this scenario, gravitons might propagate through an additional (4th) spatial dimension. Our universe would be somewhat like the surface of a hypersphere and the huge mass of exotic matter would be located somewhat in the center of such hypersphere. The actual geometry probably won't be a hypersphere of course. Thank you very much for your attention, I promise I won't bug you! Feel free to have a hearty laugh with your physicist friends about this! Share it with as many of them as possible!
