How To Destroy a Black Hole
KentuckyFC writes "The critical concept that makes a black hole black is the event horizon: a theoretical boundary in space through which light and other objects can pass in one direction but not the other. Since light cannot escape the event horizon, it must be black. The event horizon is a nuisance to astrophysicists because it hides the interesting new physics that must go on inside a black hole. What they would like is a way to get rid of the event horizon so that they can see what goes on behind it. It turns out that just such a thing may be possible, say physicists. According to the mathematics of general relativity, the event horizon should disappear if a black hole were fed enough charge and angular momentum relative to its mass. However the calculations are so fiendish (PDF) that nobody knows whether the black hole would shed this extra angular momentum and charge before it could settle into a stable 'naked' state. However, the possibility that the event horizon could be destroyed raises the question of what astrophysicists would see behind this veil. According to some, black holes are regions of spacetime with infinite curvature called singularities. Many believe that 'naked' singularities cannot exist in nature. And yet there are enough question marks to suggest that this mystery is far from settled."
On a less serious note, does Rule 34 apply to naked singularities?

Right, because anyone imprisoned anywhere must be black, because only blacks break the law and get locked up.
Information theory is life. The rest is just the KL divergence.
There are a number of factors to overcome when making singularity porn:
1. once you put it in, it's a real bitch to take it back out
2. nobody has ever successfully pulled out in time
3. they start at sucking and never manage to make it to the sex part
4. Ebony has a trademark on the term "black hole"
5. it's kind of a tease to watch because as much as they constantly approach the "event horizon", they never quite reach it

Peel back an Event Horizon? Get blasted with Radiation/Exotic particles,etc... Um just think what happens to the axis area... They are evaporating just not in a observable curvature that we can understand or detect.

Well, theoretically, (unless the theory has changed) during the big bang matter could have been compressed past the Swartzschild radius due to pressure and black-holes formed that mass much less than is required for a black hole to form today from gravity alone. http://en.wikipedia.org/wiki/Primordial_black_hole Most of these will have evaporated by now (or maybe not depending on how you interpret the string theory), but if they can exist there should still be a great many of these in the universe. We know that a black hole can carry a charge, and the surface gravity can be calculated. It is possible that there may be some of these in the solar system, perhaps in many years we will discover a way to detect them, and increase their charge to the point where they could be manipulated electromagnetically.
I love a sentence that can be misinterpreted to imply that I can retroactively change the workings of the universe based on my presumably mutable interpretation of a theory. I'm sure magic works just like this.
Does not apply to a black hole, IMO.
Not until stellar engineering encompasses more than theory.
Oblig., but not XKCD for a change.

That's racist!
We're talking about naked black holes here.
The least you could do is buy it dinner.
"According to the mathematics of general relativity, the event horizon should disappear if a black hole were fed enough charge and angular momentum relative to its mass. "
You mean... all we have to do to escape the event horizon is... reverse the polarity?
