par curiosité !
ca compense bien les risques !
The first argument is based on the observation that high-energy cosmic rays collide often with the
surface of astrophysical objects such as the moon. The total number of such collisions on the moon is
huge compared to what is expected at the LHC and, since the moon is still there and made out of ordinary
matter, one may try to use its existence to rule out the possibility of any dangerous process at the LHC.
