A black hole with stable matter

I had a question on rotating pulsars a while back. I wondered how fast it could rotate before particles started leaving it and floating off into space. Sorry to still be on the same subject here; as you can see it hasn’t left my mind.

I’m aware that inside a black hole, it’s assumed that no matter exists and there’s only a point of singularity because an infinite force would be needed to keep matter suspended above the singularity. No state of degenerate matter should exist.

But I assume this matter has a threshold of density that it can sustain right? (Weight / Volume = Some Ratio). And if this ratio gets to a certain threshold, or a ‘breaking point’, then a full collapse happens?

Since I can’t think of a way for this to form naturally, I’m just going to be superman on steroids from here on out.

I, Superman, fly to the sun and compress it to a radius of 3km or whatever this threshold is. Say that if it shrinks just a couple nanometers more, it will undergo its collapse and be a black hole. Now, I grab this ball of quarks or whatever I have and I spin it FAST while compressing just slightly. Can I compress it just a couple nanometers, and have the centrifugal force on the inside alleviate some gravity slightly due to the spin?

If so, I have a black hole on the outside as all mass is contained in that small space, yet I still have real live actual matter on the inside which I can never ‘see’.

You plan on grabbing a singularity? Good luck with that.

The event horizon (and all the rest of the structure, for that matter) of a rotating black hole is different from that of a non-rotating hole. And there’s an absolute upper limit on how fast a black hole can rotate.

In classical mechanics, if you are actually compressing it, you’ve done the deed. Spinning makes it harder for you to compress it, but doesn’t reduce the compressive force at the center (where the black hole starts).

I think the same thing would be true without restricting it to classical mechanics, though I’m not quite certain.

This thread reminds me that I was going to post a thread once I started reading The Whole Shebang by Ferris. As it turns out, I understand so little of it that it has depressed me to the point where I can barely keep from opening a vein. Muons? Tau? Leptons? Singularities? Just fucking shoot me.

Muons, tauons, and leptons aren’t that bad. Muons and tauons are basically like electrons, just more massive, and leptons are the category of particles that includes those three and neutrinos.

Take an orbiting ship and have it lower a person and a ladder past a large black hole’s event horizon. What would the person trying to climb out experience? What if the ship started to fly away?

I keep hoping for an “aha!” moment; sort of a unifying thought, if you will.

The ladder breaks some time before it crosses the horizon, and the person on the ladder can’t even point in the right direction. It’d be like if I told you to climb a ladder in the direction of last Tuesday.

Letting go is the hard part.
