so i would like to start off with what is known and work from there. equation for falling objects d = 1/2 *a*t^2 equation for solar orbits d^3 /t^2 = k or if you prefer, v^2 *d = k equation for galactic orbits v = d/k so; for the first observation, i would like to note, neither force nor mass seems to be a factor. for the second observation, i would like to note that the first and third equations flow naturally from the definitions of acceleration and velocity. so, whatever is causing objects to be attracted must a) not involve mass, and b) seamlessly tie together these three equations. i don't know what that would be, but maybe we should start here in order to work forward.
