The three main theories put forward to explain the origin and evolution of the universe are:
1.The Big Bang Theory2.The Steady State Theory3.The Pulsating Theory 1.The Big Bang theory
The Big Bang Model is a broadly accepted theory for the origin and evolution of our universe. It postulates that 12 to 14 billion years ago, the portion of the universe we can see today was only a few millimeters across. It has since expanded from this hot dense state into the vast and much cooler cosmos we currently inhabit. We can see
remnants of this hot dense matter as the now very cold cosmic microwave background radiation which still pervades the universe and is visible to microwave detectors as a uniform glow across the entire sky.
Big bang theory was supported by 2 theories, General theory of relativity and The cosmological principle.
