A complete story of the universe

in 2009 probe called planck reveal that age of the our universe is around 13.82 billion year,that is 50 million year more than we expect.

1. Inflation : (10 to 35 second after big-bang)

• in 1980 alan guth suggest that right after the big-bang an extraordinary expansion is take place in the blink of eye universe grow bigger by factor of atleast 1060.

• in 1989 NASA deployed COBE(Cosmic Background Explorer satellite) and from that we found that there is some tiny irregularity in background radiation.

• in 2001 launching of Wilkinson microwave anistropy probe(WMAP) successfully depicted Standard Model of our universe.

2. Particle creation : (1 minute after big-bang)

• at this time one of the proton trap one of the electron and create an hydrogen atom,now two such a hydrogen atom interact with each other and make a helium nuclei,some of the traces of lithium and beryllium are also found.

• 98% of universe remain in the form of hydrogen and helium rest 2% made up of heavy chemical element.

3. the decoupling of matter and energy : (380000 years after big bang)

• until this time universe had been a severely critical mass of atomic nuclei,lighter particle and energy,and this condition make impossible to form a whole atom but scenario has change.

• whenever nucleus and electron particles bonded together torrent of the radiation smashed them apart again due to above continuous expansion of the universe weaken a radiation so now proton and electron join together.
