Just to start, let me reassure you that I am not an LHC alarmist. I understand and agree with the cosmic ray explanation, i.e. earth, the sun, jupiter, and everything else would be a BH if they didn't evaporate.
Anyway, I was reading around a little on wikipedia and came to this page: http://en.wikipedia.org/wiki/Virtual_black_hole" .
So it seems like the various theories predict proton decay because of virtual black hole formation? That would explain why the predicted decay rates are so low. I take it that the virtual black hole thing is a result of the Heisenberg uncertainty principle with respect to energy and position. Am I correct about this? I recognize that virtual BHs may be a product of various unproven quantum gravities, but aren't they inevitable due to Heisenberg?
The next thing I thought was, well, since proton decay seems to have been disproven by experiment, doesn't that also necessarily preclude a quantum description of gravity by definition? I mean, Heisenberg is central to quantum, and lack of proton decay would seem to say Heisenberg doesn't apply.
So basically my final thought along this line was, if BH evaporation is based on effects derived from Heisenberg, then is it reasonable to assume that evaporation might in fact not occur? Or perhaps by a different mechanism altogether.
Does any of this make sense? Or am I wildly off base with this? Thanks!
