For some reason I’ve joined a Facebook page where people debate whether the Earth is flat or a sphere. In the last couple of weeks I’ve read some very odd speculations about how the Sun must be close to the earth and the ocean is held on the earth by an ice wall that is attached to it’s circumference.

I was interested because the author Terry Pratchett set his comic fantasy Discworld series on a similar structure. It sits atop four elephants which ride on the shell of the world turtle, the great a’tuin. To be honest his ideas are more sensible than the flat earthers!

It’s a funny and confusing page, although people do get into arguments. The scientific facts about the globe are repeated over and over again, but they are disputed and often completely contradicted by videos that are nonsensical, with descriptions that are very odd indeed.

Why do I read it? Because it makes more sense than what’s happening in the USA at the moment!
