148. The gradually changing constellations are not possible in the heliocentric model

"Quoting “Earth Not a Globe!” by Samuel Rowbotham, “It is found by observation that the stars come to the meridian about four minutes earlier every twenty-four hours than the sun, taking the solar time as the standard. This makes 120 minutes every thirty days, and twenty-four hours in the year. Hence all the constellations have passed before or in advance of the sun in that time. This is the simple fact as observed in nature, but the theory of rotundity and motion on axes and in an orbit has no place for it. Visible truth must be ignored, because this theory stands in the way, and prevents its votaries from understanding it”" 

Rowbotham makes a statement with no evidence or explanation and Dubay just repeats it as usual

I think what Rowbotham is saying is that the visible constellations at night vary.  If you are waiting for a constellation to come into view, the time that it will do so will vary by 4 minutes each night.
This is simply another example of flat earthers being presented with an observation that supports the idea that the Earth is a spinning sphere orbiting the Sun and simply stating that it shows the opposite with no explanation.

Since the earth is orbiting the Sun, it is obvious that we would expect the visible constellations to change a little every night because the night sky is opposite to the direction of the Sun.  After 6 months, when the Earth was on the opposite side of the Sun the constellations seen would be completely different.  From that point on, the constellations would continue to gradually change until 6 months later we were would be viewing the original constellations.
