The Future of the Universe; Open or Closed


There are two main theories of the Universe; Open Universe or Closed Universe. Some physicists believe that our Universe will expand forever. Other are convinced that expansion of our Universe will slow down and finally start contraction ultimately resulting in the Big Crash or Crunch. If there is sufficient matter in the Universe, gravity will eventually win and begin pulling the galaxies together again, causing the Universe to experience a reverse of the big bang the big crunch. After this a new Universe may come into being with totally different laws of nature; this is the cyclic theory.
