Mini black holes under review

For those interested, here's a paper looking at mini black holes, noting that:

a. there is no evidence that they have been produced at the LHC thus far (mind you, its next run is - I think - at about double the previous energy);

b. searches for them from cosmic ray collisions in the atmosphere might have a better chance;

c. there are a lot of reasons why they might never be found - there are a lot of things not understood at that scale.
