# Brane big bang brought on by a bulk bubble

@article{Gen2002BraneBB, title={Brane big bang brought on by a bulk bubble}, author={Uchida Gen and Akihiro Ishibashi and Takahiro Tanaka}, journal={Physical Review D}, year={2002}, volume={66}, pages={023519} }

We propose an alternative inflationary universe scenario in the context of Randall-Sundrum braneworld cosmology. In this new scenario the existence of extra dimension(s) plays an essential role. First, the brane universe is initially in the inflationary phase driven by the effective cosmological constant induced by a small mismatch between the vacuum energy in the five-dimensional bulk and the brane tension. This mismatch arises since the bulk is initially in a false vacuum. Then, false vacuum…

Brane-world cosmology is motivated by recent developments in string/M-theory and offers a new perspective on the hierarchy problem. In the brane-world scenario, our Universe is a four-dimensional…

Denouement of a Wormhole-Brane Encounter

- Computer Science

It is shown that persistence is more likely and the persistent wormhole manifests itself as a particle-like object whose interaction with cosmic matter is purely gravitational, and the viability of this object as a dark matter candidate is considered.

Entropic Issues in Contemporary Cosmology

- Physics

Penrose1 has emphasized how the initial big bang singularity requires a special low entropy state. We address how recent brane cosmological schemes address this problem and whether they offer any…
