Flat-Earth is a concept initially intended for the potential victims in the northern hemisphere. At a glance, some of the claims are seemingly in line with reality in the northern hemisphere, but they would fall apart when verified and tested in the southern hemisphere.
90% of all humans live in the northern hemisphere. It made sense for the creators of the flat-Earth notion to invent their ‘facts’ with the northern population in mind.
They merely hoped nobody would bother to travel all the way to the southern hemisphere only to verify all the claims they made up. A century ago, that was probably true.
A century ago, it would take massive efforts to travel from Europe to any location in the southern hemisphere. It was costly, and It would take a very long time. These days, we can reach Johannesburg from London for only 11 hours. A century ago, the same route would require more than a month.
Considering these facts, we can forgive any regular person in the 19th-century northern hemisphere to fall victim to flat-earth indoctrination. But we don’t have any excuses, especially for us already living in the southern hemisphere where we can readily verify the facts ourselves without traveling anywhere.
We collect some of these ‘southern facts’ in a category of the same name on our website. These are various ‘facts’ claimed by flat-Earthers, which would seemingly conform to reality under casual observations in the northern hemisphere, but would quickly fall apart into pieces when tested in the southern hemisphere.
