Example drawing from a paper on cosmology
The figure illustrates how the phenomenon of "aberration of light" can be used to explain how the
angular diameter of galaxies is increased beyond that expected for
their distance from us. While the expansion of space gives an exact value for this effect, for
small redshifts, the aberration of light gives an equally accurate answer, and furthermore
demonstrates one example of a correspondence between phenomena on the global scale and those
on the local scale.
