3. Electromagnetic Force: The electromagnetic force is fine-tuned to one part in 10^37. This precise tuning allows for the formation of atoms and molecules, which are essential for life.

4. Strong Nuclear Force: The strong nuclear force, which holds atomic nuclei together, is fine-tuned to one part in 10^40. A small change would prevent the formation of essential elements like carbon and oxygen.

5. Weak Nuclear Force: The weak nuclear force is fine-tuned to one part in 10^30. This force is crucial for nuclear reactions in stars, including the sun, which produce the elements necessary for life.

Fine-tuning in Biology

Fine-tuning isn't limited to physics; it also appears in biology. The complexity and interdependence of biological systems suggest a high degree of fine-tuning.

6. DNA Structure: DNA's double-helix structure is fine-tuned for stability and replication. Any significant alteration would disrupt genetic information transfer.
