Hubble's Law states that galaxies farther away from Earth are receding from Earth more quickly than nearer galaxies. The dots on this balloon represent galaxies. As the balloon is inflated (representing the universe's expansion), each dot moves away from all the others. To a person viewing the universe from a galaxy, all other galaxies seem to be receding. The distant galaxies appear to be moving away faster than the near ones, which demonstrates Hubble's law.
