TMR 172 : Graham (“FiveRedPears”) : On Why Flat-Earth Theory Is Flat Wrong

This week we are joined by Graham of the excellent “FiveRedPears” YouTube channel, for a fascinating and entertaining discussion on contemporary Flat-Earth Theory.

We mostly discuss some of the more well-known flat-Earth proponets, such as Eric Dubay, Mark Sargent, jeranism and TheMorgile, and I ask Graham (a mathematics teacher by profession) to assess some of their key arguments, using the logic, observation and straightforward geometry so characteristic of his video presentations. Graham also explains why the standard, spherical Earth model is in every way to be preferred, and shares with us from his experience of interacting with people caught up in the flat-Earth scene.
