The entire article attempts to use "math" to explain how the gravity of the earth proves that it is flat. When, in reality, they are just using pseudoscience that doesn't actually make sense to try to explain their point of view. They just want to use whatever numbers that they can to support their point of view, regardless on if it makes sense or not. It's a clear example of "immune to evidence" because the evidence is overwhelmingly clear against Flat Earthers yet they choose to believe it anyway.
