What is the Big Bang Theory?
The Big Bang Theory simply refers to an explanation that was given by astronomers to describe how the universe was formed, which describes a well-detailed information on how the universe started (its origin).
According to the Big Bang Theory, the whole universe stretched from a single point and then expanded to its present state and this is typically supported by the following evidence:
- Red shift of galaxies due to Doppler effect.
- Cosmic background radiation.
- Decrease in the temperature of the universe.
- Universe is expanding.
- The movement of galaxies apart.
- Existence of quasars.
