Gravity in other Universes

  1. Feb 18, 2009 #1
    In the hypothetical multiverse, is it possible for mass in other universes to be attracted to mass in our universe?

    That's the idea. Physicists are trying to explain why gravity is so much weaker than the other three fundamental forces (electromagnetic-, strong- and weak force). One theory is that gravity only appears to be weaker since it can move between universes, whereas the three other forces cannot.

    I recommend reading Lisa Randall's Warped Passages: Unraveling the Mysteries of the Universe's Hidden Dimensions.

    if it attracts mass in our universe, then we should see the deflection in our universe.
