Relationship between elements and speed of light

  1. Oct 27, 2014 #1
    I recently watched a documentary presented by Professor Brian Cox called Human Universe.

    In it he was wondering how much leeway he would have, if he was "the creator of our universe", to alter the physical constants.
    He then went on to say that if he altered the speed of light one way then there would be no carbon in the universe and if he altered it the same amount the other way there would be no oxygen.

    Can anyone start describing how this could be.
    What is the relationship between speed of light and creation of elements?

    Thanks
