You've yet to show me any indication that you understand Rowbotham's perspective, so forgive my skepticism.
I really think it's time that the flat earth fraternity dismissed Rowbotham's "theories" from 150 years ago as their sole source of "evidence", and concentrated a little more on current scientific theories established by people who haven't been dead for more than a century, and who also hold accredited academic qualifications in the various fields of science such as geophysics and astrophysics. Rowbotham held
no academic qualifications of any sort, and was totally unequipped to make the calculated guesses he did with his Bedford Level "experiments".
The only reason a handful of people accepted his experimental "results" was that in the mid-19th century, the wider population had virtually no scientific knowledge to draw upon. Very few children attended school beyond the age of 14 years—if they were lucky—and their parents were schooled in the early 1800s when contemporary science was in its infancy. So anything that was backed up with fancy illustrations and big words and glib explanations was swallowed whole without question in most cases.
Today, Rowbotham is considered by the scientific establishment to be nothing more than a curiosity of the period. He actually added not one iota of knowledge to the current scientific
magnum opus.
