Apparently, this diagram illustrates the sun's orbit and elevation above the earth's (flat) surface according to the widely accepted flat earth model...
Q1. How can the illuminated half of the earth be separated relatively sharply along a well-defined straight line from the darkened half (rather than a curved line)?
Q2. What prevents the sun—or the sun's light—from being seen from the darkened half by using a telescope?
Q3. How can it be that the north pole is always illuminated by exactly the same amount of sunlight (when it's been observed otherwise)?
Q4. How can it be that the Antarctic circle (or ice wall) undergoes a 12/12 hours period of light and dark (when it's been observed otherwise)?
Q5. How were the 12,450mile, 3,000 mile and 13.5º figures derived? Which was measured 1st and 2nd in order to derive the 3rd?
Q6. Why were the measurements taken from the underside of the sun rather than from its centre (knowing its diameter)?
Q7. Is the sun's degree of illumination identical at both the north pole and the Antarctic circle (or ice wall) locations at midday or 12PM?
Q8. How can the observed angular elevation of the sun be different at different times of the year considering its plane of orbit is always parallel to the earth's surface?
—Thanks in advance for any answers.
Since it's been a while...
What is the provenance of this diagram? Where did you find it? Who drew it?
A1. It doesn't really fit with the "spotlight" explanations of day and night you typically see here. Who knows?
A2. It's a spotlight. The light doesn't go into the dark part.
A3. Since the Sun is shown directly over the Equator, the "terminator" (line between geometric day and night) would be right at the poles.
A4. Umm... see A1.?
A5. 3,000 miles seems to be a common figure for height of the Sun (not Mr. Rowbotham's - which was much less, probably due to gross measurement error). The 12,450-mile radius from pole to "Equator" looks like an error - it's about half the circumference pole to pole but should be one quarter. That 13.5 degrees is tan
-1(3000/12450), which is the correct geometric value as sketched, even if it makes no sense (it should, of course, be zero).
A6. I suspect the triangles meet at the bottom of the Sun either because it's a poorly drawn figure, or maybe because Rowbotham seemed to prefer this as his reference.
A7. Umm... see A4.?
A8. Umm... see A5.?
(Somewhat more) seriously, I don't think this illustration represents what the FE proponents are claiming here. Their models have their own problems, but this one seems far-fetched even for them. I'm a bit surprised no one popped up asking my original questions followed by "that drawing must be a RE-believer fabrication to make us look silly!" which it might be, although unnecessary.
