WebRed-shift is detected in light from all galaxies, so they must all be moving away from each other, meaning that the Universe is expanding. Sample question 3 - Higher Question WebRed Shift and Blue Shift When the light source moves away from the observer, the frequency received by the observer will be less than the frequency transmitted by the source. This causes a shift towards the red end of the visible light spectrum. Astronomers call it the redshift. ray wright welding https://cleanestrooms.com
