Can a judge save the universe?

[Skybird]

Today I've learned (and re-learned) some fascinating things! The greater the distance to the phenomenon, the greater the fascination.

I think those fancy terms and equations means we're all dead if a black hole appears and doesn't die after a millisecond...

However, Stealth is wrong about some other bits....
A black hole sucks in things from an infinite radius in the same way the the gravity
caused by the mass of my hand attracts things to my hand from an infinite radius.
Even the most distant stars are effected by each move of my hand, but the effect
in inversely proportional to distance and proportional to mass.

The Schwarzschild radius is not the radius at which the black hole 'sucks things in'.
It is the radius at which it becomes impossible for light to avoid heading in the
direction of the singularity. i.e. it is the radius of the black bit of the black hole
when it is looked at through a radio telescope. Outside of the Schwarzschild radius
light will just be bent by the pull of the hole. Or to be more accurate, space is bent
and the light follows it.

If our sun collapsed into a singularity, the earth would continue to orbit as the mass
and gravity of the black hole would be the same as the mass and gravity of the
former sun. However, if the earth was stationary at the time, it would certainly get
sucked in from far outside the Schwarzschild radius.

If you where a foot outside of the Schwarzschild radius, but not moving closer to
the hole, you would be experiencing a force of gravity several million times that of
the Earth. That is not good for your health or completion.

I turn your attention to NASA:

Ok after your further explanations I understand it now. I had in fact not realized that the space inside Scharzschild radius is only the part of the black hole that is "black" (because not even light can escape).

After I have read your explanation, 3km sounds reasonable for that zone.

I think we can rule out the danger of micro black holes because they do not have enough mass. But what about the other problem, the exotic matter? Is it possible that the higgs field is disturbed?

I read this sometime agoand IIRC when they say scientists they are in fact the god botherers version of scientists, I think it's the head gardener and his mate...remeber these lackluster twits in your prayers says enough I think.

I just wanted to defend myself real quick on this topic.... I in no way am affiliated with either of those scientists, nor do I support their claim. The "prayers" sentence was added as a joke, as I am an agnostic. I found this while googling my site and was surprised to see someone quoted my shorthand of the actual story.

I don't see why you should defend yourself. On the other hand, it's extremely naive to post things in the internet and be surprised if it gets spread.

I'm not surprised something from my blog got spread, I was just correcting the person that wrote this "remeber these lackluster twits in your prayers says enough I think."

As if my write up was an official press release on behalf of some Christian organization. I was just pointing out that the "prayers" line was a joke.

I have no problem with scientist working on black hole matter. What I have a problem with is they're doing it on earth. If safety protocol fails we're all dead in a flash. They should do this far away like in another star system. If they botch up no real loss.:hmm: I have no interest in being turned into particles. I still need more Rum and women hehehe. I hope my wife doesn't read the last part.
