Fine-Tuning Shows Life Requires Narrow Physical Settings

  • Physicists found dozens of fundamental constants must lie in narrow ranges for complex life to appear, a phenomenon called fine-tuning.
  • Small changes to gravity, nuclear forces, or expansion rate would prevent stars, chemistry, or life as we know it.
ANECDOTE

One Rope Changed Millions Of Lives

  • John Howland fell overboard during a Mayflower storm and miraculously grabbed a trailing rope, surviving against all odds.
