    How do physicists use AIT adhesives to test
    fundamental theories about the universe? The
    answer is simple: They use it to glue stuff in the
    biggest particle detector they are building.

    The world’s most powerful particle accelerator
    under construction, Large Hadron Collider (LHC)
    at European Center for Nuclear Research
    (CERN) is to produce collision energy found in
    less than billionth of a second after Big Bang. In                                                             I must confess: I "love"
