Interesting article George, but I fail to see the relevance. The question was not about object expansion, but about relative positions of interstellar objects(Though I could conceivably see universal expansion leading to the expansion of the area of a gas cloud, it would not expand the molecules that form it, just the space between). The physics model on the wiki page I linked(which I had seen elsewhere in a lecture) clearly says that everything in the universe should be moving away from each other, not moving into a collision course at some point. So, ignore the shrinking/expanding celestial body thing for now (though that is interesting) and lets figure out how an interstellar body that should be moving ever further away from all surrounding interstellar bodies could be lining up for a collision course.
