Foliation of Timelike Hypersurfaces on Which the Khronon Phi Becomes a Constant (IMAGE)
Caption
The foliation of the timelike hypersurfaces on which the khronon phi becomes a constant, and the location of the universal horizon xi = xi_{UH}. The khronon defines globally an absolute time, and the trajectory of a particle is always along the increasing direction of phi. Thus, once it cross the horizon, the particle move toward the singularity r = 0 and reaches it within a finite proper time.
