  We generalize the Padmanabhan [arXiv:hep-th/1206.4916] mechanism to an
accelerating BIon and show that the difference between the number of degrees of
freedom on the boundary surface and the number of degrees of freedom in a bulk
region causes the accelerated expansion of a BIon. We also consider the
evolution of a universe which emerges on this BIon, and obtain its Hubble
parameter and energy density.
