Flat Earth Math | Are horizontals perpendicular to verticals? (Jeremy conversation) @FlatEarthMath | Uploaded June 2023 | Updated October 2024, 1 hour ago.
On 17 June 2023 I had a conversation with Jeremy over at the Earth Awakenings Discord server. He wanted to walk me through his conception of horizontal and vertical on a globe Earth, but had great trouble understanding what I was saying. This video is an illustration of our conversation.
