Key ideas in The Tilted Earth: Why We Don't Fall Over

  • Earth maintains a constant 23.5-degree tilt
  • The axis is not vertical relative to its orbital path
  • Direct sunlight provides more heat than angled sunlight
  • The tilt determines which half of the planet faces the Sun most directly
  • How the tilt creates seasonal changes in different hemispheres
  • Rotation creates stability that prevents the axis from 'flopping'
  • The speed of the spin is what keeps the tilt locked in place
  • Planets cannot 'fall down' in space because there is no universal down
  • Falling off the axis refers to a shift in the angle of the tilt
  • Recognition of Earth's permanent tilt angle
  • The North Star is a fixed point that happens to align with our current tilt
  • If the axis shifted, we would point at a different star
  • The relationship between the axis and the North Star
  • The Moon's role as a gravitational stabilizer for Earth's rotation
  • The extreme range of tilt Earth would experience without the Moon
  • Mars has two tiny moons that lack the gravitational strength to anchor it
