I hope this question is relevant to this thread. Why is it that I can only see the constellation Orion in the winter. I live in the northern hemisphere, east coast USA. I step outside at night during the winter, look southward and I see Orion...in the winter only.
Why is Orion only visible in the winter from the NH, and in the summer months in the SH?
In round earth terms, it's easy - Orion lies close to the plane of the ecliptic - and the Earth has a tilt of 23 degrees - so anything within 23 degrees of the ecliptic comes and goes through the year - depending on your latitude.
In flat earth terms, it depends on the map of the world. Since FE'ers either seem to use the pre-1911 "unipolar" map or the more recent "bipolar" map - you'd think the motions of the stars could be exactly mapped over the course of a year. However, the claims from other people here are "
We have no idea what the Flat Earth Map is like."...which allows them to conveniently duck the question with a hand-wavey "the stars swirl around because of the Celestial currents"...which adds a name to the effect but precisely zero new information.
I suspect that if you plotted out the known motions of the stars, planets, moon and sun in both hemispheres - then very, very weird things would happen at the equator - and possibly other places too.
Certainly some things that are observed in the real world produce VERY weird predictions in FE maps. One that I've been concerned about is with the Bipolar map. If you stand on the South Pole in December then we know that there is 24 hours of continuous sunlight. And that the sun makes a circle around the horizon - just skimming the equator the whole way around.
In the bipolar map - there is ocean "below" the South pole on the map. (I want to say "South of the South pole" - but that's silly)...and when the sun is visible at some parts of their 24 hours of sunlight - the Sun *MUST* be hovering overhead in that place.
Looking at the other places in the bipolar map - the sun would appear to be setting in the very south of their skies!
So where exactly does the sun set in the south? I've lived in quite a lot of places - and I've never seen the sun set other than in the west...give or take bit.
