I have a question.. So far, from what I've browsed on the forums, I haven't found an answer to it, and I figured this would be the best place for it. I'm aware of the balloon analogy, but I have a question regarding blueshifts and redshifts. If you take the balloon analogy, everything in the universe is expanding away from everything else, because as you blow up a balloon, you're creating more space between the dots on the balloon, so it's impossible for them to be getting closer. My question is, how can their possibly be any galaxies that are blueshifting if the balloon analogy is correct?
