To find the speed of gravity you need to determine why the dimension of the entropy of a black hole does not change with the radius of the event horizon. Then you need to relate this to a Planck mass sized black hole. Otherwise you are using wild speculation.
Considering that the wavelengths associated with gravitation are longer than the wavelengths of light then we can take c as the speed of light and g as the speed of gravitation.Then we should be able to formulate the following equation.Here lambda_0 is a specific wavelength of light and lambda_1 is a specific wavelength of gravitation. Finding the correct ratio will then give the speed of gravitation. Not easy. Not all the factors are taken into account by this simplistic relationship.
What exactly is a timing cross correlation synchronisation? I would really like to know because it confuses the hell out of me. It might sound like a very scientific thing to say but not if it doesn't make sense.
Consider being a mass of completly uniform density, a gas, liquid or solid. Next consider being surrounded by a medium of exactly the same material stretching out in all directions infinately. Would there be any force imposed on you? if the answer to this is no, why is this? If the answer to this is yes, where is the force coming from?

If the answer to this is yes, where is the force coming from?An even matter density throughout the entire Universe, is what I think you are trying to describe. If this was so, and also an even temperature for all this matter, then the amount of Spacetime absorbed by every bit of matter would be the same. That would mean that all forces acting on all parts of the Universe would be equal, and nothing would move. Spacetime would still expand with the passage of time, but there would be no clumps of Matter, and no Voids. The Universe would remain with an even distribution of Matter for ever.That is what the Universe would have been like if at the time of final scattering there did not exist the small anisotropies we now measure in the CMB.The scenario you postulate above describes an extremely fine balancing act. It would only take one small discrepancy between any two particles in the Universe to break that symmetry.But just for your thought experiment, the answer is Yes and no. Yes all the known forces of nature would be acting on you exactly the same as they would be acting on everything else.No because the sum of all the forces, because they are acting on every bit of Matter exactly the same, would have a net effect of "0". The only change in such a Universe would be through expansion.Hope that helps..
pure speculation,We might have two systems. An energy state that is uniform throughout the universe and mass that absorbs that energy to move. The energy system without mass would be a completely uniform constant. would there be any view of expansion? No, there would b no light. We only view expansion through red shift. If we are not completely sure what red shift represents we would not be sure about expansion or a big bang. Red shift is considered a SR cause and not a GR cause for expansion faster than the speed of light. Yet we view dilation as lensing which is a GR expansion of space if Einstein is to be believed (curvature of space). From our less dilated position in our galaxy all galaxies would appear red shifted just by position of dilation. Dilated space causes a longer jump for the electron which we assign less energy. And that is probably true if energy density is lowered by dilation. mass causes dilated space and dilated space expands mass. So the cell length used for detection of red shift changes with energy density position. it is not light changing frequency down a gravity well by increasing momentum as has been suggested. it is merely the synchronization parameters that change by position because of the change in cell length.So gravity is the attraction of mass to a lower density energy state of dilated space. The attraction can be related to a speed of attraction in a stationary position.
