Its part of science!

Edit : In astronomy, the Doppler effect is the change in wavelength of light caused by movement of a light source such as a star or a whole galaxy.

The term "red shift" refers to the increase in the light's wavelength from the

blue to the red end of the spectrum. This happens when a light source is

moving away from us.

I don't want to over complicate things, but there is a similar thing

called the "cosmological red shift ", but that's caused by the expansion

of space itself.

What is a Doppler red shift and a Doppler blue shift?

A Doppler red-shift is a shift in recognizable features of a star's spectrum from the wavelengths where we know they belong toward longer wavelengths. Such a shift can be caused by the star's moving away from us, and that's how it's interpreted when astronomers see it. A Doppler blue-shift is a shift in recognizable features of a star's spectrum from the wavelengths where we know they belong toward shorter wavelengths. Such a shift can be caused by the star's moving toward us, and that's how it's interpreted when astronomers see it.

How did the Doppler effect lead to the Big Bang theory?

Actually, it wasn't the Doppler-effect that lead to the Big Bang theory, but the red-shift of remote galaxies. Although it was initially thought that this red-shift might be caused by a Doppler-effect, it is now understood that this red-shift is caused by the metric expansion of space itself.
