Flat Earth Theory / Plumb bob
« on: May 30, 2024, 04:06:48 PM »
I searched and found one topic about plumb bobs and discussion about a deep mine. But I propose a simpler approach. I am pasting a Wikipedia description only to guarantee we all understand the device and how it was used.

My question is to what does the plumb bob point?
