Spinning, Black Hole

' It seems that a supermassive black hole lurks in the heart not only of the Milky Way, but of many observable galaxies. The hub of the stellar carousel is a place where space and time end, and into which stars can disappear forever.'

Dennis Overbye 'Trolling the monster in the heart of the Milky Way'

Vertigo causes one's world to spin, on a vertical or lateral axis. Like being in the hub of a carousel that is turning, and unable to stop it.  Looking back on a bout of vertigo, it is the feeling of helplessness as well as the nausea which sticks in the memory.

Being caught in a black hole would mean immediate extinction, so nothing to remember, and a much more extreme comparison with an earthly experience like vertigo or Swirl. But a 'place where space and time end' captures something of the Swirl experience, notable as it is for a feeling that time has slowed, and that spatial orientation is lost.

"Was it a curved space?
Angular? How thick were the walls? How deep was the space? How high? "

Are not these descriptors specific to a physical space, like a cave, rather than as in a metaphor?
