Over-Rotating Black Holes, Godel Holography and the Hypertube

TL;DR

This paper explores how a five-dimensional Godel universe can serve as the core of over-rotating black holes, using a supertube domain wall to resolve causality issues and proposing a new holographic relationship between Godel regions and D-brane configurations.

Contribution

It introduces a novel mechanism where a supertube domain wall removes causality violations in over-rotating black holes, linking Godel universes to D-brane bound states through holography.

Findings

Godel universe appears as the core of over-rotating black holes.

Supertube domain wall removes closed timelike curves.

Proposes a new holographic relationship involving Godel regions and D-brane states.

Abstract

We demonstrate how a five dimensional Godel universe appears as the core of resolved two-charge and three-charge over-rotating BMPV black holes. A smeared generalized supertube acts as a domain wall and removes regions of closed timelike curves by cutting off both the inside and outside solution before causality violations appear, effectively allowing the Godel universe and the over-rotating black hole to solve each other's causality problems. This mechanism suggests a novel form of holography between the compact Godel region and the diverse vacua and excitations of the bound state of a finite number of D0 and D4-branes with fundamental strings.
