Iron Isotope Argues for Supernova Input in Early Solar System

TNRTB Archive - Retained for reference information

Radioisotope studies of meteorites provide additional support for the fine-tuning of the solar system predicted by RTB’s cosmic creation model. A particular isotope of iron, 60Fe, decays with a half-life of a million years and forms only in stellar interiors. The abundance of 60Fe incorporated in compounds found in primitive meteorites confirms its presence in the early solar system. Further, the abundance of 60Fe points to its origin in a supernova that seeded the early solar system. However, the location of the supernova must be fine-tuned to adequately seed the solar system without blowing it apart. The degree of fine-tuning dramatically increases when considering other evidence that three or more supernovae must have simultaneously enriched the early solar system to account for its chemical composition. Such fine-tuning is consistent with the work of a supercaring Creator who has designed a suitable habitat for humanity.
