  1. Ok yesterday I visited a planetarium and the host said that the proof for the universes expansion lies in the red shift of stars. He also said that the red shift increases as the stars distance away from us increases. Now I thought it the the stars light takes time to reach us wouldn’t the stars closer have a greater red shift, because the light reaches us before the ones farther away? Hopefully you get what I’m asking, thanks!
