Large Hadron Collider Goes Online

For the purpose of this story, let's call this section Past Watch, for that is the purpose of the controversial Large Hadron Collider (LHC). This 27-kilometre circular tunnel will serve as the arena for some serious atom-smashing, and will give us more insight into what precisely happened when the universe began. It's also, incidentally, been accused of heralding its end--scientists have battled death threats to get this behemoth up and running.

On Wednesday, the team of scientists at CERN, Switzerland, gave the LHC its first test run, successfully sending a beam of particles all the way round the tunnel at 99.999998 percent of the speed of light. In October, two such beams will be made to collide at similar speeds, and the researchers hope to recreate the first few seconds of the big bang. The reaction may reveal new dimensions, dark matter, and what is known as the "God particle"--the Higgs boson. The particle is the only one in the Standard Model of particle physics to have never been observed, and is thought to be the reason that particles (and hence us) have mass.

With a statement like "recreate the big bang", it's hard not to think of this as the end of the world--the last big bang was pretty darn big, we've been told. However, the scientists are quick to point out that this is a controlled environment, and we aren't likely to see a new universe create itself.

And if they're wrong, what can you do?
