Scientists plan to hunt for signs of the invisible "dark matter" and "dark energy" that make up more than 96 percent of the universe, and hope to glimpse the elusive Higgs boson, a so-far undiscovered particle thought to give matter its mass.
Critics of the LHC filed a lawsuit in a Hawaiian court in March seeking to block its startup, alleging that there was "a significant risk that
Critics like Wagner have said the collisions caused by accelerators could be more hazardous than those of cosmic rays. Both may produce micro black holes, subatomic versions of cosmic black holes collapsed stars whose gravity fields are so powerful that they can suck in planets and other stars.
But not to worry say the scientists. Though if a black hole ends up swallowing the planet I guess we should just sit back and enjoy the ride as well as get used to weightlessness.
An interesting aside from TFA is the apparent data requirements of the LHC:
Each year the detectors will generate 15 petabytes of data, the equivalent of a stack of CDs 12 miles tall. The data will require a high speed global network of computers for analysis.
