If the Earth is flat - how it’s possible:
You can make the following flights, starting at 9am, finishing at 3pm (or earlier) and staying at the hotel till the next day:
-
London, Uk => New York => Los Angeles => Tokyo => Doha => London, UK
-
The above series of trips starts and ends in the same place.
-
All the time, while flying, you’ve got the Sun on the left hand side.
You can only explain that in 2 ways:
-
Earth is a globe as we know it, or
-
Earth is flat, but then it needs to have a shape of a donut where the sun is in the center of it, so you fly around it.
The second would mean: when you fly South of London you should cross the middle of a donut (which is the Sun) after 12 hours of trip.
Let’s fly towards the sun:
London, UK => South Africa => the Sun.
Unfortunately, after 12 hours you end up in an extremely cold area.
No, you can’t. The assumption of the earths orbit (and its correct diameter) around the sun yearly is baked into such calculations - for one.
Proofs do not exist outside of mathematics in an objective way. Proof is subjective.
I’m telling you that i have seen the “proofs” and they rely on unvalidated assumption.
I think this is a reasonable assumption. Many have completed this procedure and calculated the sun to be a few thousand miles away. Of course, for such calculations to be correct also requires the unvalidated (and easily refuted) assumption that the matter between the sun and observers does not alter its apparent path/position in any way. Because of air, for one, the sun often appears to be somewhere different than it actually is. Optics are tricky..
True, but the further you are from such observed points, the less accurate and dependable the procedure - for the same reasons above, and others.
There's just one problem with the procedure that just occurred to me now: If the Earth is round then the curvature of the planet would add to the observed angular difference.
