Web12 sep. 2013 · It tells us that the expansion of the universe means it is the space between objects that actually stretches, causing objects (galaxies) to move away from each other. Furthermore, any light in that space will also stretch, shifting that light’s wavelength to longer wavelengths. This can make distant objects very dim (or invisible) at visible ... 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.
