British physicist Peter Higgs gestures during a press conference on the sideline of his visit to the European Organization for Nuclear Research (CERN) in Geneva, April 7, 2008. Higgs said on Monday he expects proof will be found soon of an all-pervading force giving mass to the universe and making life possible - existence of which he predicted over 40 years ago.
