X-Ray Emissions from Black Holes

[@spicken]

Nice video, very well explained. While I was watching I wondered if some event (big explosion basically) could 'ring' i.e. circulate around the black hole. Analogous to a volcanic eruption shock wave. That could have a periodic nature, multiple echos of the same event.

Very well worded question. I was wondering the same thing myself.
