From Yahoo! News: CERN fires up new atom smasher to near Big Bang.
[T]he most powerful atom-smasher ever built comes online Wednesday, eagerly anticipated by scientists worldwide who have awaited this moment for two decades.
The multibillion-dollar Large Hadron Collider will explore the tiniest particles and come ever closer to re-enacting the big bang, the theory that a colossal explosion created the universe.
The machine at CERN, the European Organization for Nuclear Research, promises scientists a closer look at the makeup of matter, filling in gaps in knowledge or possibly reshaping theories.
The first beams of protons will be fired around the 17-mile tunnel to test the controlling strength of the world's largest superconducting magnets. It will still be about a month before beams traveling in opposite directions are brought together in collisions that some skeptics fear could create micro "black holes" and endanger the planet.
Well. I guess we'll find out soon if there's cause to be concerned.
