But you are right, sundials do not NEED to be adjusted seasonally… unless you want to accurately tell time with it seasonally. However they will remain accurate on a year to year basis without adjustment (like the ancient sundials you speak of).
“You can capture an annalema by taking a picture of the sun at one location, every 24 hours, for a whole year.”
If you do the same thing with the shadow of a post, or sundial, the same figure 8 shape will appear. The “fat” part of the figure 8 is not “minuscule” when it comes to telling time.
The noon shadow on a sundial varies and has a range of over 30 minutes throughout the year. Sundials are only accurate April 15, June 15, September 1 and December 24 (the exact middle of the analemma, and what most sundials are zeroed to).
You said sundials wont work on a globe because they would point in different directions seasonally. THEY DO, 100% fact.
Your meme also shows an exaggerated difference in “noon” shadows by not having the point centered on the globe. In the left picture, the point is set to the right of center. In the right picture, the point is set to the left of center. This will result in a more drastic angle. It is essentially comparing the 11 am-ish shadow to the 1 pm-ish shadow.
The light does appear to be centered. You can tell because the marker is oriented directly towards the camera on both pics. The reason the highlight is off the line you drew is because the camera (observer) is higher than the light (sun). The highlight would only be spot on if the light and the camera were in the exact same angle. The geometry isn't hard to comprehend. You really think you can correct that big of an angle difference with the shadow?
I told someone this in another post:
I have a public sundial that I look at down the street. All year long the thing is accurate to within 15 minutes or less. No one ever adjusts it because it's set in concrete. I would have to measure how many degrees off it is at maximum, but I would guess 1 or 2 degrees (angle of the shadow). I want to test out that globe simulation so I could get a rough estimate of how far off the shadow is between spring and fall, but if those pics are at all accurate, 45+ degrees off would equate to HOURS of error. It's not even close.
The light is on the OTHER side of the centerline. This will result in even MORE of an angle.
“accurate to within 15 minutes or less.”
15 minutes on either side is a 30 minute range, like I said. You need to “adjust” for that seasonally. The sundial does not have to be physically moved, the time needs adjustment. Can’t believe I need to spell that out.
“guess 1 or 2 degrees”
We do not need to guess, 30 minutes on a sundial is 20 degrees. Get a protractor and sundial and measure yourself. It is very funny you guessed 1-2, way WAY off.
To sum up, your 45 degree estimate is way too big. And your estimate of 1-2 degrees is way too small.
The highlight on the globe is due to the position of the observer. If the observer lowered to the same position as the light, the highlight would be centered. Draw a picture of the camera, globe, and flashlight (with the camera being over the flashlight).
Have you ever used a sundial? The position is not changed once you set it up. If you live in an area with daylight savings time, you have to account for that or else the sundial will appear an hour off. If you live in an area with no time changes through the year, your sundial will be accurate to within 15 minutes all year long.
Let's do some math. There are 360° in a circle or clock face. There are 24 hours per day. This is 15° to represent one hour. If the shadow cast is 15 min early, or 15 min late at max, this would be 3.75° of error. Like I said that is a very small angle. It would not be a 7.5° (30 min) error because you are measuring the angle between true time and the shadow cast, which does not exceed 15 min.
The light source has been placed above Georgia. This is not possible on any Earth Model. Not even flat Earth. Which is how you should know that this is controlled opposition.
Buckle up Buttercup. Because you're about to go on a ride.
In no way does analemma disprove my claim.

I know how you people continuously move the goal post, so I am done. Have a good life.

So how does a sundial work on a flat earth?
