How to see anticrepuscular rays, by Deborah Byrd in Earth | Human World
Dear readers,
Crepuscular rays, or more commonly known as sunbeams, in atmospheric optics are rays of sunlight that appear to radiate from the point in the sky where the Sun is located.
Some flat Earth advocates incorrectly point to crepuscular rays as a method of determining the distance to the Sun. Their calculations come up with a 3,000-mile figure, as indicated here below...
But their error in thinking is due to the misunderstanding of what solar crepuscular rays are, how they are formed, and why the rays appear to converge due to perspective. The reality is that the sunbeams are all PARALLEL to each other. Just like the rows of parallel flowers in the picture below...
Flat Earth people are quick to say that crepuscular rays prove that the Sun is close by. But when confronted with a picture of anti-crepuscular rays, and told that by that same logic the Sun must be below the horizon, they quickly become silent and disappear from the scene. They have no answer.
Flat Earth defenders do not endorse that the Sun ever goes below the horizon. Never. So in that sense they have invalidated their own crepuscular claims.
