As we are all scientists here, and we know you can only disprove theories, find me any data that contradicts my information, and publish it here for review. I guaranty that every city within those areas report the conditions I am implying.
BTW, this is how science is done. Kind of the opposite of how you guys operate.
"Prove me wrong" isn't how science operates. If you're coming here with unsourced daylight times you need to reveal your source. Did you make your image with the aid of historic logs or with the aid of a calculator based on a Round Earth model?
Get sunrise and set times from meterological web sites around the internet. It is public domain information and furthermore is 100% accurate.
Those are calculators. They predict what the sunrise and sunset times will be if the earth were a globe and RET were true. They operate under the pretense of a Round Earth.
Unless someone has traveled the world verifying the accuracy of the calculator we can only take it for what it is: a calculator which makes unverified predictions.
Again, the data is from a calculator based on a hypothetical model, not logs or observations which were seen in reality.
An animator could make such a daylight map for the patterns of light as seen on a torus earth. Would it demonstrate that the earth is a torus? No. It would be a hypothetical pattern which is unbacked by observational evidence, exactly as your animated patterns are here.
Hey, here's a little experiment I came up with:
I put a paper clip hanging from a string over a pan of water. In the water, I had a piece of paper just floating at the surface.
This creates a vertical rod (the string) hanging over a flat surface (the water.)
Then I measured the length of the shadow by marking the ends of the shadow with holes from a paperclip.
I measured the length of the string.
I used a straightedge to trace the direction of the shadow onto a piece of paper which I had aligned with true North using a compass and correction (for the difference of magnetic and true.).
Also The next two pictures were big, so I linked instead of posting them:
http://i51.tinypic.com/xawfhs.jpgFrom this, I calculated the sun's position in the sky. I then compared the results to a calculator based on the RE model using my (Lat, Long) coordinates and the time that I gathered the data.

And behold, in the lower left corner of the sheet with my calculations, My calculations and the RE model predictions are very similar:
58.31 vs. 58.99(RE calculated) degrees from the horizon,
218 vs. 217.23(RE calculated) from true north.

Now, I live in Western Washington. I suggest that you repeat this experiment at your own home, use the RE calculator and compare the results to yours.
