Scientists study the red shift to investigate which aspect of cosmology?
Cosmology and Arthur Eddington to explore its astronomical ramifications, which enhanced the ability of astronomers to study very distant objects. Physicists began changing the assumption that the Universe was static and unchanging. In 1922 Alexander Friedmann introduced the idea of an expanding universe that contained moving matter. Around the same time (1917 to 1922) the Great Debate took place, with early cosmologists such as Heber Curtis and Ernst Öpik determining that some nebulae seen in telescopes were separate galaxies far distant from our own. In parallel to this dynamic approach to cosmology, one long-standing debate about the structure of the cosmos
Red Shift (novel) main themes as those of "loneliness and failure to communicate". Ultimately, she thought that repeated re-readings of the novel bring about the realisation that "it is a perfectly realistic story with much more depth and psychologically more credible than the most so-called "realistic" juvenile novels." The title of the novel arises from the mind of the teenage character Tom. He talks of astronomy, cosmology and other subjects he is learning. He declares that he is too "blue", i.e. sad, and needs a "red shift". Since the cosmological red shift results from galaxies moving away from each other, this may be
