Higgs boson and higgs field
Way back in 1964, Belgium's Francois Englert and England's Peter Higgs independently theorized the existence of subatomic particles that came to be known as Higgs Boson. Recently, on 4th July 2012, CERN (European Organization for Nuclear Research) announced that they have discovered a particle that exhibits similar properties as that of Higgs Boson.
Now let’s see what is Higgs Boson and Higgs Field. There are some subatomic particles which have mass whereas there are some whose mass is negligible. Peter Higgs proposed that the reason behind the mass of the subatomic particles was the Higgs Field. We can understand Higgs Field by comparing it with water. We know that aquatic animals have streamlined bodieswhich helps them to move through the water without much drag while we human beings find it comparatively difficult to swim through water as water proposes drag on our bodies. The same is with Higgs Field. Some subatomic particles interact less with the Higgs Field while others interact more with it, resulting in negligible and considerable masses. Higgs Boson particles are like the molecules of water. They are the constituents of the Higgs Field.
In reality subatomic particles have no mass. It is their interaction with the Higgs Field that gives them mass.Higgs Bosons (God particles) are the particles that impose this interaction on other subatomic particles.
