Night Skies.
« on: December 13, 2017, 07:09:10 AM »
I am really struggling to understand why the night sky is different in the Northern Hemisphere vs the Southern Hemisphere.  Since the Earth is flat, the sky should be (for the most part) the same in both hemispheres with small variations based on a person’s exact location on the Flat Earth.

But, the two skyies are completely different.  Why?

I do have a theory that maybe some of you could put through the ringer.  Perhaps when someone is standing in the far southern portion of the southern hemisphere and looking up at the sky, they are looking in almost the complete opposite direction (180 degrees difference) as someone standing in the far northern part of the northern hemisphere and looking up at the sky.  If they are looking in complete opposite directions, then that explains why they would see completely different skies.

But I know this can’t be true unless the earth is round, which is obviously impossible.

Someone please help me understand.

Fog, limited visibility, nearby stars, mountains in the way. That's all I hear that makes any sense.

I have a related question. Does the night sky orbit the earth?

The FAQ Sun animation does not work with sundials. And it has the equinox sun set toward Seattle (well N of NW) at my house in Mesa, AZ.

Someone please help me understand.

The software developers for a program called Stellarium have this figured out.  http://stellarium.org/
Stellarium is an open source program that can display the star positions based on date/time and viewing location.  Since the program is open source, you can (or find a software developer who can) examine and reverse engineer the code.  Or, their developers have a forum.  You can ask for some guidance in that forum and maybe they will assist you with how they have been able to quite accurately predict star positions in the night sky.

It's interesting that your first sentence is something which can be easily explained by a rotating globe and your second sentence concludes that the earth is flat.

Why is it obviously impossible?

There are many things that fog cannot explain.  Such as, where ever you are on Earth try this.  On March 21 go outside at 6:00 PM and see Virgo coming up directly East.  Track it across the sky so that at midnight it is where the sun would be at noon on Sept 21.  Then at 6:00 AM see that Virgo is directly West.  Now comes the hard part.  Develop a model that can explain that one where all observers are on the same geometric plane (not an airplane).

If someone who believes in a Flat Earth will go and do all these types of observations, I do not know how they can still believe.  Go up a big hill or mountain.  Look at the angle of the sun at sunset.  How can it be above you and look like it is below you?  Draw a sketch of that.  Don't just read a bunch of stuff, go and look and think.
