The higgs boson if nothing else the most expensive particle of all time it’s a bit of an unfair comparison discovering the electron for instance required little more than a vacuum tube and some genuine genius while finding the higgs boson required the creation of experimental energies rarely seen before on planet earth



It’s been called the god particle but thanks to the efforts of literally thousands of scientists We no longer have to take its existence on faith So why the scientist had to discover new particle ? what’s it important for? how they proved its existence ? what’s the ration between the higgs boson and the universe formation ?



In the standard  model of particle physics the fundamental forces of nature arise from laws of nature called gauge symmetries and these forces are transmitted by particles known as gauge bosons and let us imagine that three is a double electron affecting on each other by electromagnetic force represent by a photon which it is exchanging photons the double electron in each other, simply imagine that the double electrons are tennis players exchanging the ball by the moving of the ball from player to another the second player will move to catch it and so on 



According to the gauge theory the weak force’s gauge symmetry should cause its gauge bosons to have zero mass but experiments show that the weak force’s gauge bosons the w and z have mass , some particles which represent forces can pass a lot of distances with high speed close to the light speed which make the forces have an influence for long range While  the others particles which have mass so it moves with limited speeds in certain places which means the influence of the forces are limited in short ranges   



In tests But it has proved difficult to find any way to explain the unexpected mass
