the planet's polite reminder that you can never see the whole story at once.
means The visible line where the earth's surface (or sea) appears to meet the sky, used in art and navigation as a reference for eye level and perspective.
from From the Greek 'horizon,' short for 'horizon kyklos' — the 'bounding circle' — from 'horizein,' to divide or set a boundary, itself from 'horos,' a limit or boundary marker. The Greeks saw it literally: the line that bounds what you can see, dividing the visible world from the unseen. It came into English through Latin and Old French around the 14th century. 'Line' was tacked on later, especially in the language of painting and drafting, to name the precise level the artist's eye rests upon.
- distance
- about three miles away at average eye level
- curvature proof
- its dip betrays Earth as a sphere
- art trick
- all parallel lines converge on it
- height matters
- climb higher and it retreats farther
- never reached
- it recedes exactly as fast as you walk
