CERN will create a quantum black hole. How does it differ from a cosmological black hole?

Question

How dangerous is this? How necessary to understand our world?

Answer 1

This Tower of Babel science is very dangerous!

Answer 2

Black holes in outer space big enough to have observable effects are huge, very heavy, and very stable.  The smaller a black hole gets, the more unstable it gets, because of Hawking radiation.  Quantum black holes, if they really exist, are so small that they are completely unstable, and should disintegrate nearly instantly.  Cern will use energies present in some cosmic rays.  If these energy levels are sufficient to cause world-eating black holes, then why hasn't the Earth been eaten?  Why hasn't the sun been eaten a million times over?

Answer 3

I love that scientists "theorize" that they will create this tiny black hole that will close its self instantly, causing no harm. what? I think its absurd to risk the entire planet on a theory. to mess with some thing of this magnitude is insane in my opinion.

maybe it will be small and maybe it will do no harm and maybe it will close instantly... but maybe it wont. then what? what do they theorize for that situation...

or maybe I'm just paranoid lol
