Both CERN and antimatter are very much a reality. 

CERN, or Conseil Européen pour la Recherche Nucléaire, is located just outside of Geneva, Switzerland and houses over 3,000 of the world’s top scientists. 

Not only are these scientists regularly producing small quantities of antimatter, CERN is also the birthplace of the Worldwide Web. (An Interview...)      

Anti-particles were first predicted by physicist Paul Dirac in 1928, and these particles were first detected in 1932. (Hawking)  The basic idea behind the existence of antimatter is that for every particle there is a mirror image anti-particle, and if one is able to separate the two, their re-collision produces a great deal of energy, or what scientists at CERN call “annihilation”. (An Interview)  

The reason that we don’t see these “annihilations” all the time, is that the “universe is somehow unbalanced, biased toward the existence of matter over antimatter.” (CERN)  So Scientists at CERN have to work in very controlled environments to produce antimatter, since it doesn’t occur in isolation naturally.  As long as research on antimatter continues at CERN, there is great promise in the creation of a 100% efficient, non-polluting source of energy.
