Sorry if this is the wrong place to post this, i am new here. I am not trying to say anything different from what we currently understand about how gravity works. I just have not been able to get a solid answer to what gravity is, and it seems it is currently debatable and misunderstood. I actually agree with all of the current known observed actions of gravity, laws of relativity etc.. at least the ones i'm aware of. However none of what i have read about our current set of laws defining gravity can explain what it is or isn't. Just the effects of. So is it wrong to say that gravity is the pressure caused by the displacement of space medium compared to the density of mass. And that space medium is a gas or liquid substance that is relatively displaced by the lack of space (mass density) in which it is trying to equalize into. Here is a simple example that would explain what i'm saying. 1. tank with a fixed amount of gas in it (control base pressure) 2. tank with the same amount of gas but there is also a ball inside (experiment) 3. tank with no gas and a ball inside. (control base ball pressure if any) so gas has a tendency to want to equalize so that means the pressure of the tank with the ball in it would be slightly higher then the tank with just the same amount of gas right? the tank with no gas wouldn't have any pressure change compared to being out of the tank. Doesn't that mean that because the physical space of the ball is dispersing the gas around it and in effect causing more pressure directly surrounding the ball (as well as the inside surface of the box), weather or not the gas pressure is focused or equalized the overall pressure would be higher right? less physical space would cause compression right? Wouldn't that explain that gravity is as simple as saying its the displacement of gas? That this space gas is so fine that we can't detect it but we can detect the effect of it. I mean it completely complies with relativity doesn't it? I would go further to say that that same principle would also explain the acceleration of our expanding universe. This would also explain the relative nature of gravity compared to other solar bodies. Not discounting any thing we have learned so far but explaining it with the simple statement space is a gas. Gas expands and displaces when object enter it causing a compression relative to the energy of the gas trying to equalize upon the object. Hrmm if that were true, couldn't we calculate the mass or size of space based on the pressure it causes on a object? I think also what i'm saying is gravity is space, that substance between the 2 objects explained in Newton's law of universal gravitation. I guess i might also be saying its not a attraction but the repulsion of space onto mass because of the want to equalize. However it doesn't change the formula, just explains the missing part that i can't get anyone to clearly explain to me. One thing different then the ball in the sealed tank experiment that would apply to us is the gas is less dispersed by less dense things, thus the effects of gravity penetrate to our core where the most dense part of the earth is. Am i missing something here, am i wrong? If i am wrong please explain to me what gravity is.
