This answer mentions the Penrose process as a potential mechanism that could change the axis of the orbital angular momentum of an accretion disk around a black hole away from the original axis of the infaling matter's source (e.g. a companion star, a galaxy) and towards the the black hole's axis of rotation.

Here I'm just asking if the theoretical Penrose process has ever been linked to an observation, or has been used as part of a potential explanation of an observed phenomenon.

  • @J.Chomel "Here I'm just asking if the theoretical Penrose process has ever been linked to an observation, or has been used as part of a potential explanation of an observed phenomenon." If the answer is no, then that would be the answer! – uhoh Aug 21 at 14:33
