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."

Thing 2: How is this a good thing to do? Aren't they basically stating that they don't understand how or why this is occurring, but they want to destroy something to figure out what goes on behind it? When are they planning to do this? December 21st, 2012?

They're scientists and engineers. "Break something to see how it works" is how scientists and engineers of all walks of life think. They're just thinking bigger than most. I gotta salute them for that.

I dont know about anyone else but....

I'm not an expert on this by any means, but here's my two cents...

Try not to think of it in terms of light trying to escape in a straight line and just not being strong enough to do it. Instead, think of the straight line as not being straight. Gravity wells curve space-time (a Google Images search for "spacetime" will yield some familiar diagrams of spheres resting on a fabric), and the event horizon of a singulatiry is the point in that curvature where it's so "steep" that it curves back in upon itself. This is difficult to show in the aforementioned diagrams, because it's less about the picture and more about the math behind it.

Basically, from behind the event horizon it's impossible to escape not because you don't have enough force to get away but because all paths lead back to the singularity.

If somebody with more knowledge/expertise on the subject can correct/elaborate, please do.
