Description

An interesting property of anti-de Sitter space is that massless fields can travel to infinity in a finite time, bounce back more focussed and collapse to form a black hole. This has recently been shown to lead to the instability of AdS against the formation of black holes. Our goal is to shed light on this by numerically examining the effect of adding higher curvature terms to the Einstein-Hilbert action. In the case of of 5-dimensional Einstein-Gauss-Bonnet gravity, for example, there exists a mass gap. That is, there appears to exist a minimum mass below which no black holes can form. It is of interest to see if this mass gap restores stability to AdS space in Einstein-Gauss-Bonnet gravity.
