It seems evident to me that the universe and our wonderful world couldn’t possibly be the result of random coincidence. True science points directly at a Creator. So does simple common sense.

Here are four examples of how God has fine tuned His creation.

The Strength of Gravity

• Gravity is incredibly weak compared to other fundamental forces, but it is precisely the right strength to allow stars, planets, and galaxies to form.
• If gravity were slightly stronger: stars would burn too quickly and violently; planets might not form.
• If gravity were slightly weaker: matter would not clump together at all—no stars, no planets, no life.
  Why it looks fine-tuned: The allowable range for gravity is astonishingly narrow—changing it by even 1 part in 10⁶⁰ would make life impossible.

The Cosmological Constant (Dark Energy)

• This constant determines the rate at which the universe expands.
• If it were slightly larger: the universe would expand too fast for galaxies to form.
• If it were slightly smaller or negative: the universe would collapse back on itself before life could develop.
  Why it looks fine-tuned: Physicists estimate it must be set within 1 part in 10¹²⁰—a precision so extreme it is often called the “single most finely tuned parameter” in physics.

The Ratio of Electromagnetic Force to Gravity

• This ratio governs how atoms form and behave.
• If electromagnetism were weaker: atoms wouldn’t hold together; chemistry as we know it wouldn’t exist.
• If it were stronger: stars could not sustain stable nuclear reactions.
  Why it looks fine-tuned: The delicate balance between these forces allows stable atoms, long-lasting stars, and complex chemistry—all essential for life.

The Mass and Properties of the Proton, Neutron, and Electron

Life depends on an exact set of conditions in the subatomic world:

• If the neutron’s mass were slightly different, atoms could not form stable nuclei.
• If the electron’s charge or mass varied even slightly, chemical bonding would break down.
• If the proton–neutron mass difference changed, stars would not produce the right elements for life (like carbon and oxygen).
  Why it looks fine-tuned: These values appear “just right” for complex chemistry to exist.
