Importance of Galaxy Cluster Environment

Astronomers have found more evidence of fine-tuning in the location of the Milky Way Galaxy (MWG), where Earth resides. By determining the star-formation rates of different galaxies, a pair of astronomers discovered that galaxies in dense clusters are nearly half a billion years older than galaxies outside of dense clusters (like the MWG). This means that star formation stopped earlier for the galaxies in dense clusters. As a result, stars in these galaxies would not be adequately enriched with elements heavier than helium, which planets and life require. In contrast, more-abundant star formation continues to later times in galaxies—like the MWG—that are located just outside dense clusters, meaning heavier-element-rich stars like the sun are more abundant in such galaxies. Such fine-tuning comports well with RTB’s cosmic creation model, in which a supernatural Creator regularly works to ensure the formation of a life-supporting planet like Earth.
