In our first year physics course we were doimg the topic of gravity and how bodies interact etc. (we were shown how to calculate the forces between bodies and saw that this force dissapated pretty quickly the further one body was from another) we were told at one point that every body affects every other body. if this is the case in an infinite universe shouldnt there be an infinitely strong force from every where else because of an infinite number of small forces? Or am I utterly wrong???
Re: Is there a simple way of proving that the universe is not infinitely large?
