You would do well to read Tom's book since he already explains the flat rotation of galaxies using the idea of the finite propagation distance of gravity.

I read an article on the idea of the finite propagation distance of gravity and found it very interesting, but my idea use an infinite propagation distance with a finite propagation speed of gravity. The finite speed of propagation imply that their will be an aberration. I am not a mathematician and my question is: will the aberration produce the observe effect on the rotation of galaxy?

Aberration will tend to accelerate the orbiting body over time and make it escape the system, it does not produce a constant velocity profile as what is observed for galaxies.

what grid msystem are using for an universe, where are you putting it in a grid? that will tell you where it has moved since then!! Please explain

Can you explain me exactly what is observed with the rotation of galaxie.

Eucledian infinite 3d orthogonal<img src=icon_smile.gif border=0 align=middle>.
Observing spiral galaxy from the top give us an "instanous" view.
Spectrum of inclined galaxy give us rotation speed.
What was observed that does not fit with the standar model prediction based on the mass estimate of luminous mater?
I know that it does not fit. I know that the standard model need to add dark mater and black hole to make it fit. But I don't remember exactly wath was observed <img src=icon_smile_shy.gif border=0 align=middle>
