Asserting that X explains Y without any attempt to provide an explanation, is meaningless unscientific nonsense; and gives the impression that you don't know and are just resorting to making things up.Erfisflat said:@Gooberry
"by all means go ahead and explain how the North Star could drop in the sky 2 degrees EVERY 140 miles travelled north/south on a flat surface."
This is perspective. I'm guessing you haven't sourced your argument because I've already refuted it in my responses. Since, no doubt you are not a Viking or Greek mariner, who navigates by polaris, I'm assuming you've done a Google to debunk me. Just saying that for 2,000 years, everyone navigated by a "linear" relationship and this is only possible on a ball is patently ridiculous, falsely assumes the distance to Polaris, and doesn't even begin to account for refraction. The Vikings, while we're talking about them, knew the earth was flat and navigated the North seas (using Polaris) for hundreds of years.
