LHC is still safe - probably

The underlying fear of the Large Hadron Collider (LHC) is that it is too experimental for any scientist to truly understand the risks.

Originally we were told that it was impossible for black holes (that could gobble up the entire planet) to be created, because they "would decay before they got the chance to do any damage".

This has been updated to:

"the growth of black holes to catastrophic size does not seem possible.”

“the expected decay times are much longer (and possibly ≫ 1 sec) than is typically predicted by other models”

By "other models" this scientist is referring to his own previous study which announced that a black hole could not last longer than one second. I find it disturbing that the language used to describe the safety has changed slightly, has become less iron-clad.
