Why is there gravity?

True. Good point. But the main reason why electromagnetism in concrete only need 1mm is because electromagnetism in the body had many more than 1mm. If both are equally stiff, I suspect each will yield many more than 1mm.

At least the GR looks ok. The idea that particles are 3d defects in space is funny. I don't understand how the proposed metric for a particle, which is not supposed to be a schwarzschild metric (?), arises. It's not written anywhere explicitely. Is this supposed to be a solution of the Einstein equations in the presence of a defect? The crucial part seems to be missing here. By the way, what are the boundary conditions at the boundary of the "cavity"? What is this "density of space" in terms of GR? Or is that supposed to be an additional concept not present in GR in this form?

Why gravity ?
Earth sucks. (can't believe I'm first to post that, and I'm too lazy to check) The granting of a pardon is an imputation of guilt, and the acceptance a confession of it.

I agree with you on the quality of the links and I do not fully subscribe to either one, but it is a good 'sounding board'. Not many subscribe to this idea at all. The various physics forums are as bad as christian fundamentalists when it comes to breaking out of their 'box'. They have no answer, but i am "completely wrong".
The math of the border is the main crux of the problem. I have been working QM bass ackwards toward the boundary, attempting to resolve the various anomalies. In particular, the various infinities that pop up and get discarded. IF the cavitation is true, then beyond the border is nothing and there would be no math (maybe the anomalous infinities). I do subscribe to a multiple reality scenario which defines 'particles' simply as 'intersections' of these different realities. For now, I am ignoring the 'particles' and concentrating strictly on the wave functions, which should include all realities and expecting the 'particles' to fall into place for individual realities. The 'density' of space would be relative to gravity on a one to one scale, similar to any cavitation. The schwarzschild equation will need some rework to define gravity as pressure rather than attraction. QM has 'proven' itself. so I certainly cannot ignore it, just rework it to include gravity as a 'medium' rather than a 'force'. And if all this pans out, there will be have to be either new words or new definitions for force, wave and particle. You might think me a crackpot (and sometimes I wonder myself), but I have always been one to observe and question from outside the 'box'. The present theories have just as many 'I don't knows" as my hypothesis. I do need to put all my notes into the computer one of these days as I find myself shuffling through reams of notes. Though I like and prefer paper, my memory is as weak as anyones' and computers do searches much better. The computer will make organization much more efficient.
You make people miserable and there's nothing they can do about it, just like god.

I still don't understand. Is this "density of space" a new property you introduce on top of riemannian geometry?
