Which one of the following is not an evidence of the big bang theory? a. most objects in space are moving away from one another b. cosmic microwave background radiation c. the light from objects in space is “blue shifted” d. most of the universe is made from light elements, hydrogen and helium

Hello there!

The correct answer to your question is c.

This is because one of the main claims to the Big Bang Theory is that "the universe is constantly expanding outwards."

When various objects, say galaxies, recede from us, their light's wavelength is elongated. This, in turn, results as the galaxy's light to look red.

When these objects are moving closer to us, it shortens the wavelength, creating a blue light. In terms of the Big Bang Theory, this should not happen, because everything is moving out.

I hope this helps!
