- This work considers objects falling into a black hole, and deduces the surprising and counterintuitive result that, measured by a specific class of observers, the infalling velocity decreases monotonically from the speed of light at the event horizon to zero at the central singularity. It extends this idea to rotating and charged black holes, and finds that the decrease in velocity is no longer monotonic. This analysis helps to illuminate more recent discussions in the literature regarding the nature of spacetime in the case of each of these types of black hole, and in particular the so-called ‘river model’.
