The Rees-Sciama effect describes how this occurs as a result of retention of energy from superclusters.
The Rees-Sciama effect describes how this occurs as a result of retention of energy from superclusters. The Sachs-Wolfe effect because of an example of this phenomenon observed in cosmic microwave background radiation, and it can be measured on earth via the Mossbauer effect, a technique first used in the Pound-Rebka experiment. Quasars have notably high values of it and it can be caused by the Doppler effect. For 10 points, name this increase in the wave length of electromagnetic radiation, named for the color at the low energy end of the electromagnetic spectrum.
