5-dimensional Myers-Perry Black Holes Cannot be Over-spun by Gedanken Experiments

TL;DR

This paper uses a refined thought experiment to test whether 5-dimensional Myers-Perry black holes can be over-spun, finding that the weak cosmic censorship conjecture remains valid at both linear and quadratic orders.

Contribution

It applies a new version of the gedanken experiment to 5D Myers-Perry black holes, demonstrating they cannot be over-spun, thus supporting cosmic censorship.

Findings

Extremal black holes cannot be over-spun at linear order.

Nearly extremal black holes cannot be over-spun when quadratic corrections are considered.

Weak cosmic censorship holds for 5D Myers-Perry black holes.

Abstract

We apply the new version of gedanken experiment designed recently by Sorce and Wald, to over-spin the 5-dimensional Myers-Perry black holes. As a result, the extremal black holes cannot be over-spun at the linear order. On the other hand, although the nearly extremal black holes could be over-spun at the linear order, this process is shown to be prohibited by the quadratic order correction. Thus no violation of the weak cosmic censorship conjecture occurs around the 5-dimensional Myers-Perry black holes.
