Event horizon just means a distance from singularity, where there is no "going-away" from the black hole. But is it possible, that there are particles with enough momentum to actually orbit the singularity under the event horizon?

  • This question however discusses orbits outside of the event horizon. I am rather interested of what happen inside. – Vojtěch Apr 29 '16 at 22:15

    Read it again, both cases are there. – Rococo Apr 29 '16 at 22:22
  • As has been mentioned on this site in numerous answers to black hole questions, the forward time-like direction is, within the horizon, towards the singularity (as usual, we assume the Schwarschild black hole context). That is, whatever it is that compels objects to 'move' forward in time compels objects to approach the singularity (if within the horizon). To have a fixed radial coordinate (circular orbit) within the horizon is as impossible as it is to have a fixed time coordinate. – Alfred Centauri Apr 30 '16 at 01:17
