    Actually DD, that technique and the compression (shock) wave it generates is similar to part of the technique to "fool" a nuclear mass into thinking it is critical by increasing its mass density. That dynamite test would be a good way to rupture every cell in your body, and essencially vaporize yourself.

    Taken from the BBC website:

    The LHC will generate huge amounts of data, with nearly 150 million sensors picking up information from millions of particle collisions every second at the centre of each of the four main detectors.
    This will produce around half a gigabyte of data every second, or around 15 petabytes (15 million GB) every year, equivalent to filling a standard 100GB hard drive every four minutes.
    To cope, a specialist LHC Computing Grid (LCG) has been built.
    The number crunching starts at the detector. Each of the four main experiments has an attached "counting room" which is used to sort through the raw data and store anything of interest.
    Batches of data are then sent to the Cern computing centre where they are backed-up on tape. A processor farm begins the huge task of crunching the data to create an event summary, also backed up on to tape.
    From Switzerland, the data is pumped out across the net to 11 so-called "tier one" centres such as the Rutherford Appleton Laboratory in the UK, each directly connected to Cern through dedicated cables.
    Each centre reprocesses the raw data, creates another back up and then pumps it out to 150 "tier two" centres, mainly universities located around the globe.
    From here, the information will be available to around 7,000 physicists who will perform the final simulations and detailed analysis.
