nother star in the same galaxy, and as long as line AB does not go through the origin(where the big bang occured/center of univesrse), then the stars are also moving apart. Lets do the same with a sun and a planet. Same result (not counting the orbits are elipitical, but circle(ar??)). Lets use two building on earth, same results (not counting plate movement). Now, let us use to atoms. Are the results the same. Yes bond forces might hold them together, yet is not there being more strain the farther we move from the origin. When this strain on the atoms become to strong, will not they break. Even if we use quarks, which have no true distance inbetween (i think) yet still occupy to seperate points in 'space'. Will not end the end those bonds break.
