Will an artificial black hole destroy the earth?

[Alex]

Yes, but to the naked eye they don't suck all the way.

As for detecting, I don't believe that Hawkings Radiation has any kind of experimental evidence yet, so it is possible it doesn't exist (which, if it doesn't, allows the black holes to exist long enough for detection) and these are things that would only be black holes at the subatomic level so I can't imagine that gravitational distortion would be strong enough (but what do I know).

And if they're saying that these things are so small that they could pass through 500,000 miles of iron without hitting another object then that makes the odds of one running into whatever kind of detector there is pretty darn tiny.

Though maybe you could use photon detectors since if one got close enough to the black hole it its direction would be dramatically altered, but then again size poses a big problem since at this scale the Schwarzschild radius is going to be infinitesimally smaller than a proton.

I'll have to do some poking around the popular sources. Pretty much everything I know about the physics of black holes is about big ones.
