Ergodically considered, the average position of the Earth+Moon over its
annual rotational period, measured from the Sun is near the center of the Sun,
and Earth's average radius vector from Earth's center approach zero. So if we
are biased in favor of averages instead of interesting perturbations, Earth
doesn't exist despite recent scientific observations to the contrary...but we
still have the number "0" we can write on a piece of paper and file away, so
that certainly motivates food for thought?
