○Higgs Boson is particle that appeared after 1billionth of a second of the Big Bang, at a time the temperature dropped to quadrillion degrees, and gave mass to other elementary particles. [1]
(Higgs boson is full of universe, the energy when the particle collides with the Higgs particle is its mass.)
１） If Higgs boson did not appear, then the other particles just fly around at the speed of light, and the substance was not born.
２） Light has no mass because it does not react with Higgs boson.
３） The amount that is expected is 62 square of 10 ％ of the energy of the entire universe
４） Spin, Electric charge：0 [2]
５） Mass：125.3 GeV [2]
※Weak force and the electromagnetic force was the same force immediately after the universe birth.
... Higgs particles are related to this symmetry breaking.
○Higgs boson is the original of 2% of mass. The principal and manifest consequence of chiral symmetry breaking is the generation of 99% of the mass of nucleons, and hence the bulk of all visible matter, out of very light quarks. [3]
○Gravity is caused by the exchange of the graviton between the ones that have mass.
※The Standard Model of elementary particles (more schematic depiction), with the three generations of matter, gauge bosons in the fourth column, and the Higgs boson in the fifth.

○July 04, 2012, Conseil Europeenne pour la Reaherche Nucleaire (CERN, in Switzerland)announced that they discovered a new particle which they could believe it as Higgs boson. [5]
○Symmetry breaking [2]
"Symmetry breaking illustrated": – At high energy levels (left) the ball settles in the center, and the result is symmetrical. At lower energy levels (right), the overall "rules" remain symmetrical, but the "Mexican hat" potential comes into effect: "local" symmetry inevitably becomes broken since eventually the ball must at random roll one way or another.
