Let's say our universe was empty, no galaxies, no stars or planets and gravity still worked the way we know it to. If we dropped two large stars thousands of light years away from each other would they eventually gravitate towards each other? If not how close would we be able to get these objects to each other before gravity pulled them together. If they do eventually meet is this why the Big Crunch is a plausible theory? Feel free to change the variables, I'm also interested if smaller objects would also pull to each other.
