Big Crunch

  1. Aug 17, 2012 #1
    I was wondering, if the gravitational pull due to dark matter is greater and at some point the universe stops expanding and starts contracting(Big Crunch)..from galaxies to stars,from stars to planets,molecules,atoms etc.and it reaches the minimum length scale Plank (according to ST) to one single point (as the Big Bang).Is it possible from that point,due to quantum fluctuations to start expanding again?And if that is,,is it possible that our universe has experienced more than one Big Bang?

    This concept is known as big bounce, see the wikipedia article and its references for more information.

    Possible, but there is zero evidence for it and everything points to continued expansion.
