 Since the initial publication of these results, Tifft's findings have been used by others, such as Halton Arp, in making an alternative explanation to the Big Bang Theory, which states that galaxies are redshifted because the universe is expanding.However, they have not found widespread support and are now dismissed by the majority of astronomers.Tifft himself, when interviewed for the popular science magazine Discover in 1993, stated that he was not necessarily claiming that the universe was not expanding.
