> this matter distribution has to be perfectly balanced for its gravity to cancel out to zero at some point? In principle, there are of course effects due to the matter distribution not being perfectly spherically symmetric about us. But except for the obvious effects that are due to nearby obvious objects--like the Earth, the Sun, our galaxy--in practice the gravitational effects of the rest of the universe on us are negligible. |
