Imagine that new evidence is found that changes how the Doppler effect is viewed. It shows that objects in the red spectrum are actually moving toward Earth and not away. How would this change the view of the big bang theory?

The universe would be contracting which would not fit the big bang theory.

Explanation:

The universe has been expanding since the big bang. If there is new evidence found that reverses the doppler effect and that the objects in space are actually going in the opposite direction, that means that the universe is actually not expanding but contracting instead.

I hope this answer helps.

yes

blue is scattered more than other colors because it travels as shorter, smaller waves. this is why we see a blue sky most of the time.
