Explain what red shift is and what it proves
WebCosmological redshift is the result of the stretching of light during its passage through space, caused by the expansion of the universe. The further the galaxy is away, the more time … WebAug 19, 2014 · Redshifts have been interpreted as a velocity of recession, i.e. that galaxies are moving through space. And that the recession implies expansion of the universe. But Hubble, up to the time of his death, was …

WebJan 24, 2024 · Bottom line: A redshift reveals how an object in space (star/planet/galaxy) is moving compared to us. It lets astronomers measure a distance for the most distant (and therefore oldest) objects in... WebMar 17, 2015 · Hubble’s diagram of velocity vs. distance appears plain and simple.It shows a clear trend of increasing velocity with distance, despite a large scatter. What makes this plain-looking graph astonishing is the far-reaching implications of the observed trend: that we live in a large, dynamically evolving universe that is expanding in all directions.
WebDear Mark, redshift is related to photons but not to interstellar bodies. Redshift or blueshift depend on physical and geometric properties of concrete cosmological model. WebAnswer (1 of 15): The Doppler Effect is a complex method in many useful ways. But in cosmology it is overrated. As we know it is defined as: “an increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move towards (or away from) each other. The effect c...
