Gravity as negative mass?

  1. Aug 26, 2006 #1
    i am thinking

    what if gravity is itself a negative mass particle?
    like, if you have something in front of a black hole right?
    how would it gain gravitational potential energy?
    if anything with positive mass cant cant out of a black hole?

    I've heard of gravity being described as negative energy, but not as a negative mass particle.
