Expanding Universe

  1. Dec 14, 2013 #1
    Space is expanding equally from all points

    Galaxies are moving away from each other contrary to gravity.

    However gravity overcomes expansion between nearby galaxies and within the galaxy and the nuclear forces overcome the expansion within matter.

    What is the formula to determine what the force is to overcome the expansion
