The God Particle

On fourth of this month CERN(European Center for Nuclear Research ) announced the discovery of a new sub-atomic particle which is been named as Higgs boson popularly known as The God Particle.

Discovery of this particle has revealed the reason behind what gives mass to all the matter in the universe. The great discovery is been done with the help of Large Hadron Collider , which is the world's biggest particle accelerator. Its a 27 kilometers looped pipe fitted 100 meters underground built over Swiss-French Border.

CERN at press release declared India as the historic father of this project. The given name to the particle is been partly shared by an indian scientist , Satyendra Nath Bose , who worked with Albert Einstein in 1920.

The researchers reported this as a 5 sigma result which implies that they are 99.9999 percent that they have discovered a new particle. One sigma implies that the test results could have random fluctuations while 3 sigma count as an observation whereas 5 sigma says that the test results are trustworthy.
With this we have now completed standard model of physics. A premise which says matter obtains mass by interacting with Higgs Field has turned into a fact . This concept can be easily understood by Cocktail Party Analogy:

Imagine a party where guests are evenly spaced in a room representing Higgs field , which is everywhere in the universe. Suddenly a celebrity enters. As celebrity passes through room, clump of guests surrounds the celebrity. Clump is harder to stop than one guest alone. So we can say that clump has acquired the mass.
