* People often read stories about the work of CERN and get very scared. “will they create another “big bang” and destroy the earth” is a common one... The big bang is very poorly understood by the public.<br /> | * People often read stories about the work of CERN and get very scared. “will they create another “big bang” and destroy the earth” is a common one...

:- 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.
