This is a bad analogy that makes it sound like you're defending flat-earthers. It's like saying you use Hermeticism's Principle of Rhythm to build a pendulum-powered clock... And unlike both Flat-Earth theory and Hermetics, Newton was actually demonstrably right . Flat-earthers and Hermeticists spin their theories out of whole cloth.
The shape of the Earth is just a model [1] - an approximation. All models have margins of error. All models are wrong, some are useful [2]. The map is not the territory [3]. All scientific models are scale variant [4] e.g contextual. Scientific models are pragmatic at best. Useful for a particular purpose within some domain of applicability When last did you take the curvature of the Earth into account when arranging…
