Old Mother Nature is capable of some pretty extraordinary feats. We go against her will at our peril.

We live at our own peril. The Catch-22 of all time! LOL

Amazing how similar the quantum affects are to the Higgs-Boson assumptions (scattering probabilities). I wonder how similar the math is after changes to the assumptions for the mass effects. Higgs-Boson Collider effects have included very small, very short lived black holes (from what I've read).

I am not sure how black holes work, but anything spinning that fast would be like a disc, and razor sharp thin, I presume, and as we go towards the centre of the disc, it would be going slower, kind of like a wheel. Eventually at dead centre we would be turning, but not at a near light speed, just at the number revolutions per second?. So if we have this mass that is enormously heavy, at least to us, spinning near the speed of light, perhaps the centre of the mass would gradually move to the outer edge and leave a hole in the middle? Or perhaps the slowly moving high density mass at the centre would gradually move at right angles to the spin and start looking like a spinning top? Either way I think the artists depiction in this article is incorrect. It is not a black ball. Another thing, I presume that the mass of the black hole spinning disc is fluid, and therefore it is not physically like a solid wheel, so most of its mass must be at the edge? And as it spins faster and approaches the speed of light, wouldn't all of the mass gradually migrate out to the spinning edge, and wouldn't it be approaching infinite mass? And would it not spread it self out so thin that it would go further and further out until it consumes the whole galaxy? Or am I talking complete rubbish?

You said it yourself Phil, if you're at the centre, you're not spinning around quickly... so why would you spin to the outside? But that's not the important part. Think if a black hole were a cone here on earth. You drop a marble in, it runs to the bottom. You flick that marble in... it spins around and goes to the bottom. You flick that marble in at 84% the speed of light and you die, but if you didn't and the cone was a super tough road cone version it'd still end up at the bottom of the cone eventually. Remember... light doesn't get out... that gradient is a bitch. If everything flattened out like that we'd be in trouble, aggregation would be a little tricky. Gravity seems to be a blackholes thing, spinning is just a byproduct from the momentum from the attracted mass. We're probably all talking complete rubbish. A name for something which has the mass of billions of our suns... arrogant little monkeys the lot of us! :P Cool article!!!!!!!!!!!!!!!

@Phil You have the idea a bit wrong. A black hole is like the ultimate vacuum, sucking things in. Think about a comet headed towards the sun, when it gets nearer to the sun it actually ends up going around the sun faster. The mass of a black hole is so large that light is unable to escape its pull. So your idea is right, but backwards.

Sorry Phil, but the salient feature of a black hole is that for anything (whether it be photons or bits of black hole) to escape from inside the event horizon, they would require a velocity greater than the speed of light, so the black hole insn't going to expand and wipe out the galaxy!
Phil
I would like to thank everyone who took the time to comment back to me about how black holes work, I guess I have more reading to do! Cheers

Mother nature's way of attempting to keep space clean? SBVC - super big vacuum cleaner?

To be moving at such speed ... speed of light, I think we should look at using this concept for the interstellar ship.
