Is the Apparent Fine-Tuning of the Universe Simply An Observational Phenomenon?

by J Warner Wallace

The just so appearance of “fine-tuning” in our universe is rather uncontroversial amongst scientists and cosmologists. Even Paul Davies (who is agnostic when it comes to the notion of a Divine Designer) readily stipulates, “Everyone agrees that the universe looks as if it was designed for life.” Oxford philosopher John Leslie agrees: “it looks as if our universe is spectacularly ‘fine-tuned for life’. By this I mean only that it looks as if small changes in this universe’s basic features would have made life’s evolution impossible.” In my new book, God’s Crime Scene: A Cold-Case Detective Examines the Evidence For A Divinely Created Universe, I describe the foundational, regional and locational conditions of our universe, solar system and planet to show how they are delicately balanced and finely calibrated for life. The slightest modification of these conditions would be disastrous. The delicate requirements for the existence of galaxies, star systems, and planets capable of supporting “intelligent observers” are incredibly fragile.

While scientists may stipulate to the appearance of fine-tuning “in the room,” this does not mean they agree on the existence of an external “Fine-Tuner”. Some scientists believe we observe fine-tuning because, if not for such fine-tuning, we wouldn’t be here to observe the universe in the first place. According to this explanation (sometimes referred to as the “Anthropic Principle” or the “Observer Selection Effect”), any humanly observable universe would display the conditions necessary for human life, so we shouldn’t be surprised to observe such conditions. As theoretical physicist and cosmologist, Lawrence Krauss, says, “Put another way, it is not too surprising to find that we live in a universe in which we can live!” Anyone who exists and inspects their environment will, of course, discover a world encompassing whatever it takes for them to exist. If they didn’t discover a world of this nature, they wouldn’t exist to examine it in the first place. But this explanation of cosmic fine-tuning fails for two reasons…
