As referenced in the paper, Verlinde proposed that gravity is an entropic force: http://en.wikipedia.org/wiki/Entropic_gravity http://en.wikipedia.org/wiki/Entropic_gravity I highly recommend Verlinde's brilliant paper, it's an easy read: http://arxiv.org/abs/1001.0785 http://arxiv.org/abs/1001.0785 The theory remains controversial, but it's a valuable attempt to put holographic principles center stage.
