We assume that their are an infinite amount of planets and that they are all about

the same mass or we will just pick a minimum mass. And we assume they are evenly distributed. So the gravitational field falls off as 1/r^2 but the amount of planets grows

as r^2. So If there were an infinite amount of planets or stars or whatever, we would experience an infinite pull, but this would be in all directions so it might cancel.

i guess this is similar to gauss's law. But how would we know where the center is or how would we balance these infinities?
