I don't have the ability to grasp the math, so i can't really figure this out on my own...
A few thought experiments
A) Dead black hole.. hasn't had any matter for millenia, that means, all the matter should(or shouldn't, depend on how you look at the theory and frames of reference) be confined to the singularity at the middle. Since there would be no granuality in the singularity, wouldn't the event horizon be a perfect sphere around it?
B) An extremely fast spinning singularity(i believe you can get a black hole that spins so fast that the singularity is actually a ring.. can't remember the name of said ring, or know if it even has one). Would such a monster(considering it would be a naked singularity) have the event horizon as a perfect sphere?
CD) the same as AB, but with the black holes having consumed some mass within the last thousand or so years
EF) the same as AB with the black hole consuming mass right now.
Just an idle thought.. Does anyone know? can anyone know?
I'm thinking, C and E may have bumps in the event horizon because of infaling matter(miniscule bumps, but there none the less).
And perhaps B would warp space around it in a way that gravitational attraction is different because of it(wait, isn't this the entire idea of how a naked singularity can be formed).
actually, this brings up another question.. if naked singularites are real, that would mean that framedragging has an effect on gravity, wouldn't that mean that a sufficiently large black hole would not have any gravity escape? or is the naked singularity just "space moving so you get speed enough to escape from the gravitational attraction of the black hole"
Wow, this post looks like crap, sorry bout that.
I promise, i'm not going ATM with this.. this is basically all my questions, no agenda or anything else in mind(Though one more black hole question may surface later).
