if an object is more red - shifted than another object, what can we determine about the two objects? (2 pts)
Answer
# Brief Explanations:
Red - shift is related to the Doppler effect for light. A greater red - shift indicates that the object is moving away from us at a higher velocity. In the context of cosmology, it can also imply the object is farther away as the expansion of the universe causes more distant objects to have greater red - shifts.
# Answer:
The more red - shifted object is moving away from us at a higher velocity (and may be farther away if the red - shift is due to the expansion of the universe).
