Question

1 multiple answer 1 point
what evidence do we have for the origin of the universe?
□ doppler effect - red shift of light
□ doppler effect - blue shift of light
□ cosmic background radiation - microwaves
□ cosmic background radiation - ultraviolet

Explanation:

1. For the origin of the universe (Big Bang theory), the red shift of light (Doppler Effect) shows galaxies are moving away, supporting expansion. Blue shift would mean moving toward, not supporting expansion.
2. Cosmic background radiation is microwave - not ultraviolet - and is leftover heat from the Big Bang, evidence for the theory. So the correct options are the ones with red shift and microwave cosmic background radiation.

Answer:

A. Doppler Effect - red shift of light
C. Cosmic background radiation - microwaves
