Sometimes what we see depicted in fictional scenes of Earth looks more like the image on the right. It seems plausible because from our vantage point on the surface the sky seems so high. Astronauts experience something which has been called the

Compare the left model which much more closely resembles reality to the right model which is very much a fantasy world. We fly through this tenuous layer as if it were our entire world—endless and immutable.
