Comment on Black Holes

  the event horizon is effectively a sphere, like inflating a donut-shaped balloon (that can’t pop). Eventually the middle hole is going to close like a sphincter (enjoy that imagery) and the whole thing will approach the shape of a sphere because that’s what anything becomes when you inflate it hugely.

  The Black hole isn’t a ring, it’s a fuckin sphere, the ring surround it in it’s equator. Grinded material more and more acelerated until almost the speed of light nearby the hole, from where it falls into the hole to end as something nobody knows. Like the swirl formed when you take out the plug of the sink, but the hole in the middle is a sphere.

    You are describing a Schwarzschild black hole. I am describing a Kerr black hole.

    Schwarzchild black holes may not exist in reality, though it is thought that rotational energy could sometimes be removed from a Kerr black hole through natural processes resulting in a Schwarzchild black hole.

    The original comment were referring to the ring singularity which is different from the accretion disk.

    The singularity is unseen, we suppose it’s a ring in rotating back holes, but we have no idea. As anything inside the event horizon, we cannot see what’s going on in there.

    The accretion disk is the disk of matter falling into the black hole, it’s outside the event horizon and can be observed.

      Supposing the singularity as an unidimensional something what we don’t know. In any case we can’t see the black hole as such, but the gravitation it causes, form a sphere arround the singularity, visible as such by the accretion disk. If not, we only can observe an black hole by its influence, eg, the gravitation lense effect.

  It is, and you won’t believe what happens!
