The post LHC universe?

Most of you have heard about the commissioning of the Large Hadron Colider (LHC) by CERN and then the explosion of Helium followed by a postponement of operation until spring next year.  One of the worries some people had was that a mini black hole would be created by the collsions.  Also, the anthropic principle in one of its forms suggests that every possible universe exists but we see only our universe because it's the one in which intelligent observers exist.

Following the shutdown of the LHC comes one of the best comments on the matter that I've seen.  From Peter Woit's "Not Even Wrong" blog on the shutdown of the LHC:

    Obviously this is the effect of the anthropic principle! In all the universes that the LHC were functioning and crossed it’s beams, black holes were created which swallowed the earth. Since we are all alive and see the LHC malfunctioning, this is evidence that miniature black holes can be created at LHC. This is really the first experimental data the LHC have produced. It’s amazing how much new good science this anthropic prinicple makes possible!


    Does anyone know what exactly went wrong in the latest round of LHC problems - from the mechanics point of view?

    CERN has released a report on what happened at the LHC.  The report can be found here.

    It appears that it's taken a month for the tunnels to warm up enough for people to go in an inspect the damage.  The damage appears to be extensive but the details are not clear from the report.  The proximate cause seems to be the failure of some spring-loaded relief disks to contain the pressure at 0.15 MPa.  The ultimate cause is still unclear.

     A video of how the LHC works can be seen below.
