Lead ion collision at the Large Hadron Collider. This is the world's highest-energy particle accelerator. Up until now, they were colliding protons. Using lead ions, they created temperatures a million times hotter than at the centre of the Sun.
Now THAT'S a particle accelerator. One of my dreams: to visit the Large Hadron Collider (LHC).
