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???
