A May 31, 2007 file photo shows a view of the LHC (large hadron collider) in its tunnel at CERN (European particle physics laboratory) near Geneva, Switzerland. One huge scientific experiment being launched Wednesday, Sept. 10, 2008 is described as an Alice in Wonderland investigation into the makeup of the universe, or dangerous tampering with Nature that could spell Doomsday for the Earth. The first beams of protons will be fired around the 27-kilometer (17-mile) tunnel at the launch Wednesday to test the controlling strength of the world's largest superconducting magnets. It will still be several weeks before beams traveling in opposite directions are brought together in collisions that some skeptics fear could create micro black holes they theorize could endanger the planet.
