Physical life is not fluid. It will not and cannot adjust to any old universe. The fine-tuning that astronomers observe indicates that even very slight alterations to the universe’s characteristics would rule out the possible existence of physical life.

More than 140 different ‘exterior’ features of the universe, including the values of the constants that govern the laws of physics, must fit within narrowly specified ranges. This reality reasonably points to a Source with the capacity for intentionality, for deliberate, purposeful design and implementation—in other words, a Creator who transcends the well-crafted cosmos.

There appears to be no end to the evidence of fine-tuning and design coming from scientific discovery.

If a purposeful Tuner exists, it makes sense that the deeper our search into the features of the cosmos, the more evidence of fine-tuning this search will reveal. If no purposeful Tuner exists, then a deeper search will reveal less and less specificity and intentionality. A fine-tuner’s attributes and purposes will become either increasingly clear or increasingly vague.

My hope is that evidence for the exquisite fine-tuning observed at all astronomical levels, from the farthest reaches of the cosmos to the ground beneath our feet, arouses a profound sense of awe and wonder. My greater hope is that this awe and wonder will inspire readers to ponder the deep questions raised by a close-up glimpse of nature’s unfolding story.

Just as the interior structure of our supercluster of galaxies, our galaxy cluster, our galaxy, our local galactic neighborhood, our star, our system of planets, asteroids, and comets, and our Moon differ from the normal pattern in precise ways that favor the possibility of advanced life on Earth, so, too, does Earth’s core.

Neptune’s complex migration history, known as the ‘jumping Neptune’ altered the Kuiper Belt’s properties in the ways, all of which have a bearing on the possibility for advanced life and civilization on Earth.

[The features of Earth’s mantle], among others, appear so intricate and specific that Earth may well be the only rocky planet on which plate tectonic activity, at a survivable level for life, has been operating for an extended period, much less approaching 4 billion years.

The scientific content of Genesis 1-11 holds special significance for me because it revolutionized my thinking and, thus, changed my life’s direction. Until I reached my late teens, my singular passion was science, astronomy in particular. My life’s purpose was to learn more about the universe; nothing beyond that really interested me.
