Did you know:
  • That antimatter is routinely produced at CERN (more than 10 million particles per second).
  • That the world's largest magnet, weighing more than the Eiffel tower, is at CERN.
  • That the vacuum in the Laboratory's accelerators is the best between CERN and the moon.
  • That CERN's biggest accelerator is 27 kilometres around, and particles travelling near the speed of light lap it over 11000 times each second.
  • That CERN's detectors are the size of four-storey houses.
  • That over 1800 physicists work on the biggest experiment being prepared for CERN's next accelerator (the LHC). This experiment will generate data at a rate about equal to everyone on Earth simultaneously making 10 telephone calls each.

Taken from the CERN homepage - sorry about that.
