I usually don't refer to "Ken Pig" but he does have a decent article on the flat earth.
10 Reasons We Know the Earth Is a Sphere
During a lunar eclipse, the earth’s shadow is always circular. Only a sphere casts a circular shadow regardless of its orientation.
As we travel northward, stars above the southern horizon disappear below the horizon. Conversely, stars below the northern horizon become visible. The reverse happens as we travel southward.
The hulls of ships disappear first as they move away from the observer. (This observation doesn’t always work on warm days because a temperature inversion can bend light along the earth’s curvature.)
From very high altitudes (50,000 feet or more) the earth’s curvature is visible.
When surveying triangular areas greater than 200 acres, the sum of the interior angles exceeds 180 degrees. If the earth were flat, this would not happen, but it would if it were a ball.
The Coriolis effect is an important physics phenomenon that impacts the atmosphere. A rotating earth causes this effect, but there is no explanation if the earth is flat and motionless.
Astronomical bodies appear to spin around the north celestial pole every 24 hours. Telescope mounts must compensate for this motion. This works only if the earth is a spinning ball.
The moon, the sun, and the other planets clearly are spheres. By analogy, one would expect the earth to be a sphere too.
If the earth were flat with a dome over top, everyone on earth would see the same stars. But we don’t—a large part of the sky is not visible from temperate latitudes in the Northern Hemisphere and likewise in the Southern Hemisphere.
In the Northern Hemisphere stars appear to spin each day around the north celestial pole (the North Star is very close to the north celestial pole). In the Southern Hemisphere, stars appear to spin around the south celestial pole (but there is no bright “south star.”) This is not possible on a flat earth but must be true if the earth is a spinning globe.
Dr. Danny Faulkner joined the staff of Answers in Genesis after more than 26 years as professor of physics and astronomy at the University of South Carolina Lancaster. He has written numerous articles in astronomical journals, and he is the author of Universe by Design.
