Are you referring to black hole and the jets of particles they emit? I don't think this image works here because of the time dimension (but I may have answered too quickly... haver to think more).

Yes, and I thought the planar rotating disc with polar jets was found in other systems as well. Remember I'm an armchair cosmologist and get my theories in that field mostly from sources aimed at the interested public ;)

No problem. I have tried to answer with what I think here. I think this image does not apply here (I have trouble to make the analogy working with this damned time axis :D).
