Part 4/9:
Another pivotal argument Meyer raises is the "Goldilocks zone"—the observation that the fundamental parameters of physics are extraordinarily fine-tuned to support life. For example, the cosmological constant, responsible for the universe's expansion, is set with such precision that tiny variations would preclude the existence of life—either causing a rapid collapse or an ever-expanding, lifeless universe.
This fine-tuning suggests to scientists that the universe wasn't a happenstance arrangement but the result of intelligent calibration. Physicists like Luke Barnes have written extensively on this topic, for example in his book The Fortunate Universe, highlighting how the precise balance of forces points toward an intelligent designer.
