I was wondering....
Suppose, a tiny black whole is created. And suppose Hawking-radiation does not happen to exists (as far as i know, it has never been confirmed to exist yet), so the black hole will not evaporate itself into this radiation... how dangerous is such a black hole?
The energies that are used and produced are extreme to our senses, however I think they are still nothing compared to the forces and energies found in the galactical black holes.
So, how quick will it grow? Will it be possible to suck up the earth in a matter of minutes, or will it take millions of years?
In the latter case, I think it will just sink to the center of gravity of the earth. There it may first wobble about around the CoG, and (later) have some growing impact on the rotation of the earth as it gets bigger.
(Could it be possible we already have a tiny black hole down in the center, due to collisions from radition from outer space, which helps keeping the earth spinning?)
What do you think?
