Abstract | We use a rubber balloon model to give a simple explanation of the motion of photons and galaxies in an expanding and collapsing universe. In particular, we study the Friedmann- Lemaitre-Robertson-Walker closed universe. The behavior of the peculiar velocity of galaxies in an expanding universe is also studied with the help of this model. © 2007 American Association of Physics Teachers. |
