Because we complete a full galactic circle every 250 million years, in our brief epoch
we are always traversing uncharted cosmic coordinates — never where we have been before,
and never knowing what lies ahead.
Continental positions before the modern era are an illustrative reconstruction
(rigid drift of real satellite imagery, not surveyed plate data). Cloud cover is today's, shown
unchanged across all eras for visual continuity. Ice extent, sea level and vegetation are a
stylized model, not measured data.
