Question

1. the big bang theory is the theory that about 14 billion years ago, the universe began with a massive explosion (big bang) of an extremely dense and very small point. how does the doppler effect / red shift provide evidence to support the big bang theory?

Explanation:

The Doppler - Effect/Red - Shift shows that light from distant galaxies is shifted towards the red end of the spectrum. This indicates that galaxies are moving away from us. If all galaxies are moving away from each other, it implies that the universe is expanding. The Big Bang Theory posits an expanding universe starting from a single point. So, the Red - Shift provides evidence for the expansion of the universe as predicted by the Big Bang Theory.

Answer:

The Doppler Effect/Red - Shift shows that galaxies are moving away from us, indicating the universe is expanding, which supports the Big Bang Theory's prediction of an expanding universe starting from a single point.
