My first post here, hope to have more...
I have an idea/question probably brought about by watching too much Discovery Channel and I don't know who to ask, but I found this place so here goes.
Consider a black hole of radius r at the centre of a steel ball of radius R, where R>>r. I am not considering how it got there or whether steel is important - its just the way it is.
Now I am led to believe that the interior of the steel ball would be consumed by the black hole, until one of two things happen; either
a) the steel ball is completely consumed or
b) a state of equilibrium emerges where the interior is hollowed out leaving the black hole at the centre of a steel shell which resists further consumption because of the compressive strength of the ball and the distance of its thick shell from the black hole.
my question is - what is the ratio of R to r for condition b) to arise and what kind of gravity would the steel shell have compared to the earth?
