That's what Newton believed, but a more careful look reveals that the integral over all space that determines the gravitational force does not converge to a well defined value. See for example the dynamics of Newtonian cosmology.

Thanks, I appreciate the response. I like the discussion of convergence and the care to consider the shape of the volume in the limit of infinite size.
