But if CERN can
produce non-decaying micro black holes, then
cosmic ray events should produce some too.
This analogy is defective. If I understand it correctly the LHC will
bang millions of particles together at once. So comparing it with what a
cosmic ray does is like comparing an atom bomb with a single uranium atom.
        Idiot.  Any given proton will collide with at most one other
proton.  We expect 10-20 collisions each time the beams cross.  Each
collision is totally independent of any other collision. There is no
additive effect.
If a single black hole forms, won't it collide with other protons?

        In the time it takes to decay from Hawking radiation?  

So who the *** knows how long that is?

Get real!

Hey, not everybody has a "Dr." in front of their names.

You should answer legitimate questions without the ivory tower
attitude.

The protons are held apart by electrostatic repulsion, it takes a _lot_
of technology to keep the beam from flying apart.

And wouldn't that effect be additive since it's a black hole?

        No, it has to encounter another proton first.  

Then the answer should properly be: Yes, but it has to encounter one
BEFORE it decays, which you imply above is unlikely.

We're talking
(IIRC) timescales of something like 10^-34 seconds here (and of course
O(10) collisions per interaction, times the probability for BH formation)..
I'd sooner expect the pink elephants...

I guess now we know what drives cranks in the first place.
