The Hubble redshift in atomic spectra of distance cosmic objects, discovered by Edwin Hubble around 1929, is claimed as a source of evidence for the [[Big Bang theory]].<ref>Edwin Hubble (1929). [http://www.pnas.org/cgi/reprint/15/3/168/ "A relation between distance and radial velocity among extra-galactic nebulae"]. 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. It also suggests either that the universe is undergoing accelerating expansion for an unknown reason, or that there exists [[Hubble time dilation]] causing such an effect in stationary [[Einstein's universe]]. The latter effect is expected by observational predictions of [[Einsteinian gravitation]]. It also complies with the [[perfect cosmological principle]].

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.

However, creationist cosmologies also predict this expansion, so the evidence cannot be used in support of the Big Bang theory over creationist theories especially that the Big Bang hypthesis is also a creationist theory as it asumes that the universe was ''created'' 13.7 billion years ago.
==Redshift according to Perfect Cosmological Principle and Einsteinian gravitation==
According to the [[Perfect cosmological principle]] that says that the universe looks everywhere and always approximately the same the redshift is a feature of [[curvature of space]] which in general relativity theory is coupled to the rate of time. As a result we see the more redshift the farther we look since the space is also more curved the farther we look. The exact relation between the [[curvature of space]] and rate of flow of time is
:<math>d \tau/dt=exp(-r/R_s)</math>,
where <math>\tau</math> is time in observed deep space (proper time of that place), <math>t</math> is time of observer, <math>r</math> is distance from observer to the observed point in deep space, and <math>R_s</math> is radius of curvature of space.
According to this principle the universe looking always approximately the same is neither expanding nor contracting and existed always and therefore was never created. Furthermore because of such relation between redshift and the distance the universe looks as if it was expanding with accelerating expansion which was noticed in 1998.
