ON HIGGS BOSON ( OR ) GOD PARTICLE

World has witnessed many great moments.
When Galileo proved the Heliocentric  system.
When Einstein theory on Spacetime Curvature was proved.
When an atom was exploded.
When Cosmic Microwave Background Radiation  was discovered, etc
To-day the entire Physicists community and elites of the world  are joyful.
It is because of the discovery of new particle consistent with the Higgs particle.
Many of my students had sent mails  asking me  to explain in simple terms .
.
Q: What is Higgs particle ?
A : Higgs Particle nicknamed as God particle is a subatomic particle.
 This particle is responsible for  making  any  particle to gain mass.
Light is made of photons ( energy pockets ) but they do not have mass.
It is because , they do not have Higgs particless in them.

Q : You mean Higgs particles help matters  to gain mass?
A: Yes. Without gaining the mass , there cannot be gravity. 
Without gravity,  the formation of the  Universe would have been impossible.

Q : What is the life time of  a Higgs  particle ?
A : Do not be astonished, it is one millionth of the billionth of a billionth of a second. Afterwards it will decay.

Q : Why  this particle is so important ?
A : When the Universe was formed about 13.5 billion of years ago, the scattered matter gained mass and formed universe. If  there were no Higgs particles, the Universe would not have formed. There would be no atoms, no matters, no stars, no galaxies and no Universe.

Q :When this Higgs particle was formed in the Universe ?
A : After the Big bang  explosion , within  a trillionth of a second ( 1 Trillion = 1000 billion ).
the Higgs particles are supposed to be formed. These particles helped other particles to gain weight.
Because they gained weight, the Universe came to a shape.

Q : How the scientists were able to locate this particle now ?
A. The Scientists are very careful in using the terminology, they say they had discovered a particle consistent with Higgs particle, they have miles to go
In CERN  using  powerful  collider they were able to achieve this.
In Physics, it is a great moment, a moment of joy.

Q :  Actually how this Himalayan  task was possible by the scientists?
A : Protons were accelerated by using colliders to the speed nearer to the speed of light .
The speed of light is 3,00, 000 Km /sec. 
According to the Special theory of relativity nothing can travel faster than this speed.
Scientists accelerated the collider to 99.99999991% of the speed of light.
Higgs particle or Higgs Boson was exploded.

Q : Why the term Boson is used.?
A : Named after the Indian scientist S.N Bose.(Satyendra Nath Bose ).
Bose worked with Albert Einstein to bring out Bose-Einstein condensate in 1920.
He was the pioneer to work on this subject  before Peter Higgs spoke of it.
To honour him , it is named  Boson. Since Peter Higgs of UK worked on it  in 1964 , it is named Higgs Boson.

Q : How this discovery is going to help.?
A : There are many mysteries in cosmology, which remain unsolved.
For example  "dark matter ", it is present in between galaxies and push the galaxies far away.
In fact this dark matter ( dark energy ) helps for the expansion of the Universe.
Scientists are without proper knowledge about this dark matter. This is called dark matter because  the knowledge on it is dark or blank. Infact it is not dark in colour. Knowledge on it  is dark.
Discovering of Higgs particle will find answers for these questions.

Q: Why it is called God particle ?
A: It is a misleading name, this particle as nothing to do with God.
In 1933 Physicist Lederman book was named " God Particle " by his publisher.
This name had somehow entered  in this subject to mislead us.

Q: What is use of this discovery ?
A: what is the use of just born infant ?
