Uh huh, sure. I apologize I just can't muster enthusiasm to discuss this topic anymore. The earth is a globe shaped thing, all data supports that. I have yet to see a single convincing argument to the contrary that is grounded in reality.
A wide angled lens when capturing the spherical earth would also show curvature. There is no image of the earth with out curvature, weather baloon images of the planet exhibit a shape that is consistent with a sphere the size of our planet and can be modeled. The whole thing is just a snooze fest for me.
Not sure what you mean by that? 14mm lenses create distortion at the edges.
All data supported Einstein's theory that nothing can travel faster than the speed of light, until quantum physics proved otherwise. All the best to you my friend :)
