What does the term "fine-tuned universe" imply regarding physical constants?

The term "fine-tuned universe" implies that the physical constants and fundamental forces in the universe are specifically configured in a way that allows for the existence of life. This idea suggests that if these constants were even slightly different, the balance necessary for the formation of stars, planets, and ultimately life itself would be disrupted. The delicate interplay of these constants provides an environment that is remarkably conducive to the conditions required for life to thrive.

For example, the strength of gravity, the electromagnetic force, and the nuclear forces have precise values that enable processes such as star formation and the stability of atoms. This concept often leads to discussions in cosmology, physics, and philosophy regarding the implications of such precise tuning, including the possibility of multiple universes or the existence of a designer.
