The laboratory is being constructed beneath an old goldmine, which itself was once the site of renowned physics research. The fact that it’s sheltered from cosmic rays makes it a great potential locale for the mysterious dark matter particles, which may make up a quarter of the universe’s mass and do not “feel” the electromagnetic forces that affect ordinary matter. According to the AP:

The research team will try to catch the ghostly particles in a 300-kilogram tank of liquid xenon, a cold substance that is three times heavier than water. If they tried to detect dark matter above ground, the highly sensitive detector would be bombarded by cosmic radiation.

And while scientists have been running tests and warming up its accelerators to prepare for the day, something else has been heating up: an online video of a rap about the LHC, created by Kate McAlpine of Michigan State University.
