If you've ever imagined yourself at the controls of the world's biggest and most expensive science experiment, now is your chance.

Built by more than 10,000 people from across the world at a cost of €10 billion, CERN's Large Hadron Collider is a 27-kilometre circular particle accelerator buried beneath the Swiss-French countryside. It smashes protons together in order to find out how atoms and other fundamental particles work.

It's also where the world wide web was developed by Tim Berners-Lee.

Now you can wander its corridors, experience near light-speed collisions and discover the mysterious Higgs boson right here in Sydney.
