I Difference between oscillatory/cyclic model and big bounce?

  1. Nov 2, 2017 #1
    If a Big Bounce can occur "after a universal singularity is reached or a repulsive quantum force causes re-expansion" then what differentiates it from oscillatory/cyclic models if both of them defend that the universe will re-expand from a singularity or before that?

    The Bounce only assumes a single bounce event (there may be more, but only one is necessary). Cyclic models include a large number of bounce events (possibly an infinite number).
