Since the universe is expanding after the big bang, galaxies are moving away from each other as first determined by Hubble. But, our solar system and our galaxy (and any galaxy we look at) is not expanding. To bring the point down even further, the earth and its parts (down to atoms and sub atomic particles) are not expanding either. If everything was expanding at the same rate, we could not detect the expansion.
How can the universe be expanding but the individule parts not be?
