wow of course latitude and longitude are not the same thing... don't play stupid. I am talking about plotting two points one on a chart based on the spherical Earth and then one on the flat Earth map you guys got. The lat/long is the same for both points, but the position on the chart and map would be different. The Flat Earth map is simply wrong. The countries are not in the right positions compared to reality.
Also, you are playing stupid again, where did I say I have a spherical map? are you talking about a globe? then yes I have a globe. You are really not grasping what I am saying here are you? It is pretty simple. The Flat Earth map is wrong. that is not where everything is if you tried navigating to them using a chart.
While I am still here, There is a funny problem I am trying to wrap my head around. If by your diagram of how on a Flat Earth we travel in an arc (looks like a circle), then how can you stay on one general direction. To me, if I was doing a large flat Earth arc (circle) I would be constantly turning and not staying on a course (or roughly on that course depending on corrections and changes)
In reality the arc that you travel while sailing is a more of a vertical arc, and not a circle. You are following the Earths curve while you travel so you are still heading in a straight direction.
And what is the stupid Learn2physics crap? come on now, when have you ever been on the bridge of a vessel while it is navigating around a land mass. You notice course changes pretty easy while up there.
