Actually, it's interactions with the moon that are the most telling. Since this is a heavy ion collider, it's colliding nuclei that are much larger than those found in the earth's atmosphere. When they disproved this crap before the Relativistic Heavy Ion Collider turned on they found that the most powerful constraint came by considering heavy ion interactions when a cosmic ray hit the moon rather than the earth's atmosphere (even though the earth is bigger, to properly compare with conditions at RHIC, you need to look at the number of heavy ion collisions). If collisions at RHIC were to create strangelets or blackholes, then the moon would have been destroyed long ago.
