THE BIG BANG AND THE UNIVERSE

According to the astronomers and cosmologists, time and space began with a mighty cosmic explosion known as 'the big bang'. Although this name might not sound serious enough for the origin of the world, the theory is solid and most scientists support it. But we will never know exactly what happened at the dawn of the universe.
I give below some salient features of big bang theory.
At the moment of big bang the radius of the universe is almost zero. After
10 to the power -43 seconds (a negligible period of time ), the radius of the universe is less than 10 to the power -50 centimeter (which is also negligible).
THIS CREATES THE IMPRESSION THAT SOME SUPERNATURAL FORCE (MAY BE GOD), CREATED THE UNIVERSE FROM NOTHING (EMPTINESS). After 10 to the power -35 seconds the universe has grown and its temperature is 10 to the power 27 degrees celsius. one second after the big bang, the universe is an undifferentiated mass of matter and energy. Its temperature is 10 to the power 10 degrees celcius. 200 seconds after the big bang Helium and other light elements are created through nuclear fusion. 800,000 years after, the universe becomes transparent. Matter releases radiation, later to be discovered in the form of microwave radiation in cosmic background radiation. 1000million years after big bang, birth of the proto-galaxies took places. Most of these remain outside the range of our instruments. After 3000 million years, evidence of quasars and some radio galaxies took place. 8000 million years marked the birth of most galaxies including the Milky Way ( our galaxy). Birth of Sun and planets took place after 9000 million years. First life on Earth was created after 13000 million years after the big bang. This is all about the origin of the universe as per the big bang theory.
