No. The wave view leads to a realistic model that produces directly the GR equations and de Broglie equations exactly and in a clear and easy to understand way. For example http://nz.youtube.com/watch?v=8BTcmuGdLCU shows the actual de Broglie waves as being phase modulation of the standing waves. Several different people have independently found that the WSM leads to all de Broglie's equations. I strongly suspect that de Broglie was fully aware of all of this himself, as he felt that much of his understanding was never picked up by the physics community. Probably this is a language problem.

Only one unknown parameter is needed to get both the red shift and gravity, so one of these can be used to determine the other.

The only area where there is no quantitative results established is particle physics beyond the electron. However there is a very clear method that is available to anyone to test that and it is far easier to do so than to work with trying to improve present particle physics. If successful it would be orders of magnitude more easy to work with and make things clear at a much more fundamental level. The important thing is that there is no evidence against the proposal which makes it attractive to investigate further.

It is much more attractive than something like string theory because Maxwell's equations are well established already. A famous physicist (I forget which one) once said that whatever is permitted by the laws of physics is compulsory. There are certainly spherical standing wave solutions to e/m equations. If these solutions are not actually particles, then where are they and what are they? It makes eminent sense as Clifford realized well over a century ago.
