Be honest.
What is actually proven fact?
I'm not worried about the outcome of the earth. ( that's already safe )
I just hope nobody gets hurt locally.

trekkor, we who care to get our heads out of a book of fairy tales,
do know a good bit about how the universe works
and are trying to learn more
''Well, the smallest possible black hole is around -10to the35 metres across (the so-called Planck Length). Anything smaller just gets wiped out by the quantum fluctuations in space-time around it. But even such a tiny black hole would weigh around 10 micrograms--about the same as a speck of dust. To create objects with so much mass by collisions in a particle accelerator demands energies of 1019 giga-electronvolts, so the most powerful existing collider is ten million billion times too feeble to make a black hole. Scaling up today's technology, we would need an accelerator as big as the Galaxy to do it.
And even then, the resulting black hole wouldn't be big enough to swallow the Earth. Such a tiny black hole would evaporate in -10to the 42nd seconds in a blast of Hawking radiation, a process discovered by Stephen Hawking in the 1970s. To last long enough even to begin sucking in matter rather than going off pop, a black hole would have to be many orders of magnitude bigger. According to Cliff Pickover, author of Black Holes: A Traveler's Guide, "Even a black hole with the mass of Mount Everest would have a radius of only about -10 to the15th metres, roughly the size of an atomic nucleus. Current thinking is that it would be hard for such a black hole to swallow anything at all--even consuming a proton or neutron would be difficult." ''
BTW in a long read on this subject
what they are up to is running gold atoms together at very high speed
but every day gamma rays hit us at even higher energy's with no black holes seen
