Just because it increases doesn't mean it increases by a certain factor. y=x also increases, but y=ex increases far more, and y=x! increases even more than that.
I believe they've done the calculations using the Schwarzschild equation and showed that it does increase faster. Or so I understand from reading wiki articles and such.
I agree with this scenario, but there's a problem: you have no idea if the black hole is spinning quickly enough for that to happen. How fast does a star's nucleus spin when the star is dying? How much does it accelerate before collapsing?
Granted, but I don't think we've actually observed a star collapsing into a black hole, so at the moment we don't know for sure what happens to it; all we have is predictions. I did look up to see how fast pulsars can spin, which is as much as 3000 times per second before the angular momentum should overcome the star's gravity. So a black hole would have to be spinning faster than that to avoid a collapse. Since we can't observe a black hole's mass directly, I don't know how we could tell how quickly it was spinning.
There's also a possibility that it could be spinning rapidly enough to keep from collapsing without actually coming apart. I don't know how fast it would need to spin to do that, however. Also, the Schwarzschild metric (how they calculate the radius before it turns into a black hole) apparently doesn't apply to a rotating object, which complicates things.
I think my brain had an orgasm from that article, but it doesn't really explain something that I saw as the problem in your statement. Specifically, the part where you said "wherever it ends up". Were you referring to white holes?
Ah, my mistake. I was referring to a different article
which said that the matter might end up elsewhere in the universe or in another universe entirely.
Regarding your follow-up question, I haven't really worked with that level of math before, and thus I'm not sure how well I could work with it. Also, as I stated before, the problem with plugging an infinity (such as the infinite density that a singularity is believed to have) into an equation is, what do you do then?
I must now perform seppuku to prevent further contamination of the English language.
Can I be your second? I mean, if you're going to eviscerate your intestines, it might help to have someone ready to chop your head off before it gets to be too painful.
