I believe that LHC will produce mini black holes that will not evaporate.  Several reasons.  First the idea that mini black holes will evaporate is cavalier wishful thinking.  Would we accept such assurances from a biotech lab? Suppose the lab reported revolutionary benefits of conducting an experiment where they insert small pox genes into an influenza host--with the solemn assurance that any and all samples will immediately be destroyed.  Would we just let them waltz on ahead?  I think not.

The other reason I believe that the mini black holes will be stable is because I am advancing a revolutionary new model, the Dominium, that suggests that mini black holes will stay stable as voracious matter compacting beasts.  Debate has been hot and heavy on my Scientific American blog. http://science-community.sciam.com/blog/Hasanuddins-Blog/300005039  I invite anyone to come on over and join the "fun."  You wouldn't believe some of the harsh words that my detractors have against me.  The funniest thing is that the people with the harshest words adamantly declare that they have never read the model.  Go figure?  Of those who have read the model, they have nothing but positive things to say...though they all hope that I am wrong about the stable mini black-holes, or, if I am right, that LHC can be stopped in time.  

If you do chose to join in the discussion, please read the model first.  You can download the half-version at http://www.sendspace.com/pro/dl/u56srb or you can purchase the full book (the paperback is more complete) at online bookstores
