The Correct Answer is Option 4 i.e All of the above.

  • Big Bang Theory is also called the expanding universe hypothesis.
  • Big Bang Theory considers the following stages in the development of the universe:
    • In the beginning, all matter forming the universe existed in one place in the form of a tiny ball with an unimaginably small volume, infinite temperature and infinite density.
    • At the Big Bang, the 'tiny ball' exploded violently that led to a huge expansion. It is now generally accepted that the event of big bang took place 13.7 billion years before the present.
    • Within 300,00 years from the Big Bang, the temperature dropped to 4,500 K and gave rise to atomic matter and became transparent.
    • The expansion of the universe means an increase in space between the galaxies.
