God may have been around before then — but as far as scientists are concerned, the big bang is as far back as they can go. And to get back there, they're getting ready to blast subatomic particles so energetically that the extreme conditions of the freshly born universe will be re-created on Earth.
Will those "little big bangs" crack age-old scientific mysteries? Or, despite repeated assurances from the world's top experts, will they create black holes that could gobble up the planet? After decades of preparation, scientists are finally switching on a machine that will separate the facts from what is plainly science fiction.
