and it's associated with something called the higgs megaisim in, named after peter higs. somehow we believe that there's essentially a higgs field, a field that's something that permeate it is universe. and in some sense there's a mysterious charge throughout the universe that the barrels were all bouncing off and in some sense that's how they're acquiring their mass. >> rose: could this experiment taking place prove higgs right? >> absolutely. absolutely. i mean, i think that people really believed that the higgs... was right there. 's strong theoretical reasons. we know that these particles shouldn't have mass in some sense. we know that they do have mass and we know that if they had mass fundamentally it would lead to all sorts of nonsensical predictions. so this mechanism is a beautiful way of accommodating all these theoretical and experimental facts so we believe the higgs mechanism there. the fantastic something that if it's right, there should be experimental signature of it. there should be a remaining particle which is known as the higgs-boson. and that's a part
