Not anymore. Its structure is a remnant of the motion of the accretion disc that most of the bodies interior to the Oort Cloud formed from. That disc is no longer present, but its plane remains evident.johnnydeep wrote: ↑Wed Aug 26, 2020 2:24 pm Cool! And based on that, I gather that the Kuiper Belt is concentrated enough to interact hydrodynamically - acting like a liquid? - and therefor become disk-like. I need to take a physics course...
Well, as I noted, I'm not sure what effect that plays in the special case of the accretion disc around a black hole. Only that if we have material orbiting any massive body at different inclinations, it will always settle to a disc if the density is high enough to result lots of collisions.Ok, neat. But maybe the relativistic frame-dragging at least helps? Intuitively, it seems like it would - though I know intuition often fails - mine especially - in explaining relativity, and quantum mechanics :ssmile:
