The Large Hadron Collider and Future Energy Sources

What is the Large Hadron Collider? How can a particle accelerator simulate the big bang? What are our options for energy in the future? Dr Dave tackles these questions on this weeks Ask the Naked Scientists. We also find out why the moon doesn't rise and set like the sun, how ships can carry heavy cargo without sinking and why melting icebergs won't actually change our sea levels.
