The Big Bang Theory

DescriptionThe Big Bang theory is a theory that states that our universe was once empty, but then a super massive gaseous point that exploded and sent superheated particles all over space.

1st Piece of Evidence
The earliest observation was the expansion of the universe according to Hubble’s Law discovery and measurement of the cosmic microwave background and the abundances of light elements produced by the Big Bang’s nucleosynthesis.

2nd Piece of Evidence
This is a support to the idea of the Big Bang model because it found Doppler shift, which confirmed that our universe is growing.

3rd Piece of Evidence
Lastly, a telescope named BICEP2, found inflation in light 380,000 years after the Big Bang.
