What is Big Bang theory?Explain.

Big bang theory is a theory that tells how universe, that is space time and matter was formed in the universe. This theory was derived mathematically from equations of general relativity by the Belgian monk Georges Lemaitre that gives a creation point of the universe. 

Chief features of Big Bang theory are 

  1. All points that comprise our universe was confined to a single point of infinite temperature, infinite density and known laws of physics does not hold at that point.  
  2. An explosion occurred at that point about 13.75 billion years ago and point began to expand, real time started. It can be thought as small marks on balloon being inflated.

The?big bang?is how astronomers explain?the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now (and it could still be stretching).

The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it says the universe as we know it started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today.

Big bang is a theory given for birth of the universe. According to this theory all the mass in the universe was concentrated at one place, which exploded to give birth to all the stars, planets and other celestial bodies.
