How does sunsets work on flat Earth?
They can't possibly work on a flat earth. No model of the sun works on a flat earth.
If the earth were flat:
The sun would seem to move faster as it got closer
The sun would seem to get bigger as it got closer.
I could not go to the top of a tall building and see the sun set again
High clouds could not still be lit from underneath after sunset
At the end of December, at about 8am Sydney (Australia) time, the entire continents of Australia, South America, most of North America, and the entire Pacific Ocean are under sunlight. At the same time Europe, Asia, and Africa are in darkness. I have never seen a flat earth model of a sun that can explain this.
