Question 12 of 13

1

How does the Doppler Effect help explain the Big Bang Theory?

Select one of the following:

Big Bang Theory says the universe is expanding. All light seen from earth is blue shift and has longer wave lengths meaning that the object sending the light is moving away from us.
Big Bang Theory says the universe is shrinking. All light seen from earth is blue shift and has longer wave lengths meaning that the object sending the light is moving away from us.
Big Bang Theory says the universe is shrinking. All light seen from earth is red shift and has longer wave lengths meaning that the object sending the light is moving away from us.
Big Bang Theory says the universe is expanding. All light seen from earth is red shift and has longer wave lengths meaning that the object sending the light is moving away from us.
