An utterly incomprehensible paper has been produced by a team of physicists, designed to make everyone feel better about the possibility that the Large Hadron Collider will produce black holes that will suck the Earth into themselves.
There is no effort whatsoever in this paper to speak to normal people. The most I can get out of it is that yes, black holes can form, and possibly very many of them, but it will take them longer to destroy the planet than it will take the sun to destroy the planet by exploding on its present schedule (of some billions of years from now). Which makes no sense to me at all until I saw this in the paper:
Ah, that makes me feel so much better….
