On Tuesday March 30 the LHC produced the first proton-proton collisions at the record energy of 7 TeV. Many congratulations to CERN and all involved in the LHC for this incredible achievement !

Cosmic accelerators produce the cosmic radiation that interact in the Earth atmosphere with energies that largely surpass this humanly made record energy. However, this happens not under controlled conditions and the number of observable interactions that will be produced at the LHC will be much, much larger. Therefore the discovery potential for the LHC and cosmic ray experiments, such as the Pierre Auger Observatory, is different and complementary.

To show that while we will have fun with cosmic rays at Cosmic Experience, the LHC also has its entertaining sides, we show this clip:
