The redshift in atomic spectra of distance cosmic objects is claimed as a source of evidence for the [[Big Bang theory]].<ref>Edwin Hubble (1929).

Proceedings of the National Academy of Sciences 15: 168–173.</ref> The redshift, the expanded wavelength of light, suggests that these objects are moving away from Earth due to the expansion of the universe. This is a phenomenon predicted by the Big Bang theory. However, creationist cosmologies also predict this expansion, so the evidence cannot be used in support of the Big Bang theory over creationist theories. | The redshift in atomic spectra of distance cosmic objects is claimed as a source of evidence for the [[Big Bang theory]].<ref>Edwin Hubble (1929).
