:- Video - Official CERN intro video – they collide particles together at high speeds to squash them up to recreate these very high densities and then watch what happens. It is not true to say they smash up atoms to see what is in them – more they create particles from (kinetic) energy.<br /> | :- Video - Official CERN intro video – they collide particles together at high speeds to squash them up to recreate these very high densities and then watch what happens.
