This serves as the place for Flat Out Hero and MCToon to have a discussion of the AE map.  This is in response to Flat Out Hero's YouTube video titled "Wolfie quit WOOFIN! Hahahaha, I can fly circles around you, you ain’t no PILOT!!!!"

I ask that participants be kind and engage respectfully.

Question specifically for Flat Out Hero to answer:

Someone in Argentina faces due south and someone in Australia faces due south, according to the AE map, they are facing nearly opposite directions. They both see the Southern Cross constellation. Show how this is possible.

This is one variant of the map to be examined.  If a different one is preferred, please include it.

Easy. It can be proved that every point on the perimeter is actually the same point, so you are both facing the same point, ergo the same direction.

Hello edby!
You are right, for a "polar azimuthal equidistant projection", but ...
That's the same error, I did with the bipolar model. Do not interpret the presented image:
FE claim, this IS the flat earth map, or a least a coarse model of it. And there IS an Ice Wall around the perimeter.
The image is just "accidentally" looking like a projection of a globe earth.
So the OP question is valid...

Ah yes. Then the Southern Cross is a real problem.

[edby]

This is the most powerful objection to the FE hypothesis I have encountered.

1.   Are lines of longitude curved or straight? Straight, because (i) if we follow a path in the same direction as the Pole star, we must be travelling in a straight line (ii) every point on that line must have the same longitude.* Thus only the AE map is valid (the bipolar map has curved lines of longitude, e.g.).

2.   But if the AE map is valid, the southern cross must appear in different directions depending on the longitude.

3.   But it doesn’t. So, if the FE hypothesis is true, the AE map is the only valid representation of the world’s surface. But it is not valid, ergo etc.

I don't see any way of answering this objection.

*I define a line of longitude as the set of points where the time of high noon is identical.

Why is some completely unknown individual (who, to my knowledge, has no activity here) expected to answer specific questions here?

In other words: why is this an upper-fora thread?

[edby]

Perhaps rename it or something? The challenge is a powerful one. If the AE map is correct, then the Southern Cross cannot appear due South to observers at different longitudes. Yet apparently it does.

Oh come on. Then tell me that you can see the Ursa Minor from every point in the northern hemisphere. Well of course you can cause the stars rotate! So you stay still and wait till the stars are so that you can see them. Easy as that.

Neither pole star nor southern star (sigma octantis) rotates.

Here is one (which has little or no warping away from the equator):



And another one (which has some warping further away from the equator)

The second one will not work.

[edby]

The question is always whether the line of longitude is the shortest distance between any two points on that line. If so, then the AE map is the only possibility. But then we have the problem of the South Polestar.

YouTube comments sections are poor places to have meaningful discussion.  Forums like this one are better.  Being he is a flat earther I invited him to a place that favors him.  In the end he deferred.  It seems he doesn't trust this particular FE faction.  I don't understand the factions.  This thread can be left to die, or move to a lower-fora, or continue with the current discussion, I'm fine regardless.

Why not?  Is there something wrong with it?

Lines of longitude, see my comments above. Lines of longitude must be straight.

It's the "AuthaGraph" globe projection map. Here is how it was formed moving from a globe to a flat map:

Straight? Well in the round earth model lines of longitude are curved as they would be drawn on the surface of a sphere shaped object. By your logic the only possible map of the earth could be a flat earth map.
