# Emergence and expansion of cosmic space in an accelerating BIon

## TL;DR

This paper extends the Padmanabhan mechanism to an accelerating BIon, demonstrating how degrees of freedom differences drive cosmic expansion and deriving related cosmological parameters.

## Contribution

It introduces a generalized model of cosmic space emergence on an accelerating BIon, linking degrees of freedom to universe expansion.

## Key findings

- Degrees of freedom difference causes accelerated expansion.
- Derived Hubble parameter for universe on BIon.
- Calculated energy density associated with the expansion.

## Abstract

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.
