Lots of funny comments.

FYI: If my memory serves me correctly Grant money for similar experiments was withheld a few years ago and the experiments were ordered to be stopped immediately while a panel of physicists examined the proposed experiments.

The reason why? What if a group of scientists working in particle acceleration lab created a BLACK HOLE that was above some level of stabilty (ie. large enough that it didn't immediately dissolve because of Hawking Radiation)?

Would it "run away" and devour the Earth? In other words, one minute I'm tying this message and the next mi.......................

The human race disappears without any warning. Poof!

well, I know I've read theories that black holes have passed right through the earth so maybe these small ones can be fun. And even if it does suck us in, we'll all find out what goes on inside a black hole. Please try to look on the bright side of these things.

That was what I was thinking of when I saw this article.

Sorry, but your premise is flawed. The lifetime of a black hole depends on the mass-to-surface area ratio. Since the mass itself determines the surface area, that means the lifetime of a black hole depends on its mass, and exponentially. Unless you can get something of about planetary mass compressed to the applicable radius - a challenge for any laboratory environment - the decay will be essentially 'immediate.' Even planetary mass black holes decay in fractions of a second. All the cool 'black holes passing through the earth' ideas were pre-Hawking.
