54) “At places of comparable latitude North and South, dawn and dusk happen very differently than they would on a spinning ball, but precisely how they should on a flat Earth. In the North dawn and dusk come slowly and last far longer than in the South where they come and go very quickly. Certain places in the North twilight can last for over an hour while at comparable Southern latitudes within a few minutes the sunlight completely disappears. This is inexplicable on a uniformly spinning, wobbling ball Earth but is exactly what is expected on a flat Earth with the Sun traveling  faster, wider circles over the South and slower, narrower circles over the North.”

See claim 53.This claim is similar, but with Dawn/Dusk

The lengths of twilight are, indeed, different in the two hemispheres. However, this can be explained by axial tilt and the fact that the earth's orbit is an ellipse [Brian B's Climate Blog]. Due to what is essentially conservation of angular momentum, it means that as the earth is further out it spins slower.

A lot more can be said about this, and there have been books written solely to calculating this sort of thing. I won't diverge much more here.

So, we see that once more they assert their alternative model doesn't have these problems without showing this assertion to be true.

What's more, they rely on an extremely oversimplified picture in the reader's mind. And then capitalising on this simplified picture, so as to make you doubt it..”
