Web26 aug. 2024 · There are three main mechanisms which produce redshifts (and blueshifts): 1) Kinematic motion of an object through space ( Doppler Effect ), 2) Expansion of the universe, or the space itself between the object and the observer, and 3) Passage of light through distorted space-time caused by strong gravity fields. Web3. Explain the Doppler shift. 4. Explain how all galaxies are similar. 5. Think Critically All galaxies outside the Local Group show a red shift.
