I mean, where is the black hole described in BotNS? How is it 
characterized sufficiently to make those proceeding inferences?

Something on the order of an earth-mass black hole with hand-sized even 
horizon is what I had in mind. This would imply that the White Fountain 
would be of a similar magnitude and why it would do such a job on Urth 
as it passed along.

Oh, of course. I'm just saying that a hypermass of a vague order of 
magnitude can have effects that qualitatively resemble what's in the book.
