Fine-Tuned Amounts of Far Ultraviolet Radiation

American astronomers discovered another design feature for the solar system: a just-right amount of far ultraviolet (FUV) radiation. Their study demonstrated that the intensity of FUV radiation from nearby stars at the time our Sun’s circumstellar disk was condensing into planets determined the kinds, masses, and distances of the solar system’s gas giant planets and the mass and extent of the Kuiper Belt objects that exist beyond Neptune’s orbit. If the FUV radiation was any stronger, Uranus, Neptune, and the Kuiper Belt would never have formed and Saturn would have been smaller. On the other hand, if the FUV radiation was any weaker, Saturn, Uranus, Neptune, and the Kuiper Belt would have been much more massive. Either situation would yield devastating consequences for life on Earth. Thus, the FUV radiation level at the time of the condensation of the solar system’s circumstellar disk adds to the list of hundreds of characteristics that must be fine-tuned for life. The accumulation of fine-tuning evidence makes the case for the God of the Bible as the Creator and Designer of the solar system progressively stronger.
