BBC NEWS | Science/Nature | Lab fireball 'may be black hole'
"A fireball created in a US particle accelerator has the characteristics of a black hole, a physicist has said."
...
"These form a ball of plasma about 300 times hotter than the surface of the Sun. This fireball, which lasts just 10 million, billion, billionths of a second, can be detected because it absorbs jets of particles produced by the beam collisions.
But Nastase, of Brown University in Providence, Rhode Island, says there is something unusual about it.
Ten times as many jets were being absorbed by the fireball as were predicted by calculations."
...
"However, even if the ball of plasma is a black hole, it is not thought to pose a threat. At these energies and distances, gravity is not the dominant force in a black hole."
So, we created a blackhole that our calculations said we shouldn't have made, but don't worry, our calcuations say there is absolutely no danger.

Well said. As long as we realize something is impossible just after it has been done, there should be no problem in declaring that we know enough about it to know that that which we couldn't have done was completely safe, we think...
