Here is what my science listserv folks came up with!
ReplyDeleteAssume we’re in the northern hemisphere, facing south, so the sun and moon are rising in the east and setting in the west. So far, so good. However:
1. The moon does not appear as a sphere, i.e., you can see the stars behind what should be the shaded part of the moon.
2. Moon is wrong phase, e.g., when rising opposite the sun, it should be full. Alternatively, one could say that the moon phases do not comport with the time of moonrise relative to sunset.
3. Moon phase changes too quickly from one day to the next.
4. The moon phases are going in the wrong direction, i.e., starts with waning crescent, proceeds to full, and then waxing phases appear.
5. The moon rises at the same time each day (right after sunset).
6. The height of the noontime sun does not change with the seasons, and the sun’s path across the sky in the course of the day is the same throughout all the seasons.
7. There’s an immediate change from dark to light.
8. The sun is pulsing.
9. The stars are stationery, rather than moving toward the west along with the sun and the moon.
10. The stars do not change with the season.
11. Relative length of day and night does not change or correspond with the season.
