A better understanding of how a galaxy’s spiral arms form reveals the special location and timing of the solar system. As dense molecular clouds pass through the spiral arms (regions of star formation that spiral out from the center), they drag material from the spiral arms into the voids as they leave the arms. As this material makes additional passes through the spiral structure, further substructure forms. Thus, as spiral galaxies age, they develop so much substructure that the probability for planetary systems, like the solar system, to encounter disruptive dense regions dramatically increases. So, a life-supporting solar system must form sufficiently late for stars to produce the life-essential metals but before the extensive disruptive substructure forms. The solar system not only formed at the proper time, but also its location allows it to avoid the disruptive substructure for the longest possible time. Such fine-tuning challenges evolutionary models but is predicted by RTB’s cosmic creation model.
