The Higgs boson (named after a certain Scottish #physicist , Peter Higgs) is an unusual kind of #subatomic particle.
In our current theory of #particle #physics , fundamental particles do not have mass on their own. They get their mass by interacting with the the #Higgsfield . The field is a concept like a magnetic or gravitational field: it's present everywhere. (Unlike a magnetic or gravitational field, though, the size of the Higgs field doesn't change much from place to place.) #Higgsbosons are ripples of the Higgs field. By finding the Higgs bosons, we have evidence that the field itself exists - like seeing water waves and concluding there must be an ocean beneath.
The Higgs field is extremely important in #particlephysics . It's no exaggeration to say that it makes your existence possible. Without it, #atoms would not exist; #electrons would zip away from #nuclei at the speed of light. The value of the Higgs field determines what kinds of nuclei are stable and some of the differences between matter and #antimatter . Almost all particles we know of are affected in some way by the Higgs field.
In 2012, 48 years after the idea was proposed by Peter Higgs, the existence of this particle was observed in the Large Hadron Collider at #CERN .
