When we analyze the light from distant stars, we find that their light tends to be redshifted. Furthermore, the amount of redshift seems to increase with distance from us. Scientists

took this relationship and applied it to the Doppler Effect, thinking about it in terms of how fast those stars must be moving away. Take a look at this video for more info: 3A) What is the relationship between the distance a star is from us and the speed with which it seems to be moving away from us? 3B) What does this relationship indicate about the universe?
