The Noble prize in physics 2019

The Noble prize in physics 2019 was awarded for contribution to our understanding of the evolution of the universe and the and the earth place in the cosmos. One half of the amount to James Peebles “for theoretical discoveries in physical cosmology” and the other half of the amount jointly to Michale mayor and Didier Queloz for the discovery of the exoplanet orbiting a solar-type star.

   

   
     

The Bigbang theory describes the universe created above 14 billion years ago. after that, the universe becomes denser and colder barely 400,000 after the Bigbang the universe becomes transparent and light rays able to pass through the universe. The universe continuously moving away from each other. The hydrogen in each galaxy will gradually be gradually used up and the galaxies themselves will become fainter and fainter.

     
         Using his theoretical tools and calculations, James Peebles was able to interpret these traces from the infancy of the universe and discover new physical processes.
         
His theoretical work from the mid-1960s with the four bases of contemporary concepts of the universe.
The result showed that our universe only five percent of contents are known as planets, stars and us. The rest 95 percents are the unknown dark matter and dark energy.

   
      In October 1995 Michale Mayor and Didier Queloz announced the first discovery of a planet outside our solar system, an exoplanet,  Orbiting a solar-type star in our home galaxy, the Milky Way. At the Haute -Provence Observatory in Southern France, Using custom-made instruments they can able to see the planet pegasi 51b, gaseous ball comparable with the solar system’s biggest gas giant, Jupiter.
