What costs $6.7 billion and 13,000 man hours to recreate? The conflagrated conditions of the universe when it was only one trillionth of a second old. The 20-mile-long International Linear Collider "will use 16,000 superconducting cavities to accelerate electrons and positrons to extremely high energies." Scientists hope to learn a great deal about the endowment of mass and the future of spacetime. And fret not, even though they'll be replicating the conditions of the Big Bang, that doesn't necessarily mean that they're going to create a second universe that overlaps with ours.
