Abstract:
Possible astrophysical consequences of the Hořava quantum gravity
theory have been recently studied by several authors. They usually
employ the Kehagias-Sfetsos (KS) spacetime which is a spherically
symmetric vacuum solution of a specific version of Hořava’s
gravity. The KS metric has several unusual geometrical properties that
in the present article we examine by means of the often used technique
of embedding diagrams. We pay particular attention to the transition
between naked singularity and black-hole states, which is possible along
some particular sequences of the KS metrics.
