Centred on the North Pole. Antarctica is on the outer rim.
I’m trying to wrap my head around this concept.
Any explanations out there?

Edit: I am in the “Earth is a globe” camp but over the years I have heard from Flat Earthers and more recently to boot. No one has given me an answer to what is beyond the edges. They say Antarctica rims the disc. As crazy as it seems, I am looking for a logical explanation to change my mind or I maintain my belief in the Globe Theory. I am curious. Thanks for all the input but need a Flat Earther to take a stab at what is beyond.
