THE BIG BANG OF UNIVERSE THE ORIGIN OF THE UNIVERSE ‘Origin of life ’ begins with the origin of the universe.The universe an old wast and empty space comprising of galaxies originated around 20 billion years ago. There was nothing but blackness filled with gas and dust. The ‘Big Bang Theory’ is the most accepted theory regarding the origin of the planet earth and the existence of different life forms on it. According to this theory the universe is the result of a massive explosion which occurred 20 billion years ago. Whether it is hypothesis on a fact, new universe was formed the atmospheric condition after the explosion became more stable. When the universe began it was just hot ,tiny particles mixed with light and energy.The tiny particles grouped together, they formed atoms. Then these atoms grouped together and gases like hydrogen and helium formed which led to the formation of galaxies and stars of today. After,10 billion years the earth was formed ;which was covered by water vapour, methane, carbon - dioxide and ammonia. There was no atmosphere but only gases and moisture. The powerful rays of the sun stimulated and hastened the evolution. By making and breaking of bonds between gas molecules,earth came out With a new face. After millions of years I e , once earth ’s atmosphere was stabled the first life on earth came into Existence (around 4 million years ago). There began the story of origin of life. There were lots of hypothesis regarding the origin of life on earth. Certain experts suggested that life came from outer space as spores while another group explained that life came from a non –cellular component such as Decaying matters like mud.The latter theory was known as the theory of Spontaneous generation which was discarded later. In the year 1953 , Oparin and Haldane suggested that life originated from non – living organic molecules like proteins and RNA . This was followed by the theory of chemical evolution which suggested that atmospheric condition of earth led to the formation of organic molecules from the inorganic molecules . Few scientists conducted experiments regarding the same. Nowever , once the first life came into existence ,they started to evolve in different ways and forms. അർച്ചന .എസ് 8 E എൻ എസ് എസ് ജി എച്ച് എസ്‌ പന്തളം പന്തളം ഉപജില്ല പത്തനംതിട്ട അക്ഷരവൃക്ഷം പദ്ധതി, 2020 ലേഖനം *കാല്പനികത മരിക്കുമ്പോൾ  സാങ്കേതിക പരിശോധന - Manu Mathew തീയ്യതി: 25/ 04/ 2020 >> രചനാവിഭാഗം - ലേഖനം
