This got me thinking about gravity's effect on antimatter.

  Same gravitational "polarity" for both matter and antimatter. There is no repulsive gravitational force.

    The inflation models of the universe actually depend on repulsive gravitational force, but it requires a very specific set of circumstances for it to happen.

    In theory, but I'm not sure if actual results have been published yet: http://arstechnica.com/science/2013/04/does-antimatter-fall-up-experiment-could-provide-the-answer/ http://arstechnica.com/science/2013/04/does-antimatter-fall-...
