Are the particle accelerator, they keep saying it's safe and that 'mini' blackhole may open up, however they will be so small with nothing to keep it together for too long, so they'll vapourise in seconds.
Of course I'd hate to think if the scientists make a miscalculaton or are wrong.
And mistakes can happen, it's only human (from the wikipedia link):
Quote: "On March 27, 2007, there was an incident during a pressure test involving one of the LHC's inner triplet magnet assemblies provided by Fermilab and KEK. No one was injured, but a cryogenic magnet support broke. Fermilab director Pier Oddone stated 'In this case we are dumbfounded that we missed some very simple balance of forces.'"
If there's a small mistake or something missed, then will it be stabl or safe?
If nothing goes wrong it'll be interesting to hear the results, though arguably it's a lot of money to spend on such an invention to propose a similation for the big bang, but not proving it happened, just how it may have happened. Though I suppose such an invention might prove later to have other uses.
