Where is the Curve, Flat-Earthers?

46AND2 · Mar 2, 2020

I should point out something significant:

We observe the sun, twice a year, trace a path from due east to due west along the equator. It forms a straight line.

What this means is that EVERY SINGLE flat earth model that depicts the earth's equator as a circle must be wrong, right off the bat. There are no lines in a circle. It is mathematically impossible for us to observe what we do, if the equator is depicted as it is on...well, pretty much every flat earth model I've ever seen.

"Distances: The biggest problem are distances on the flat earth. Only distances exactly north-south are correct. All other distances are wrong, especially south of the equator, eg. Australia is 2.5 times too wide on the flat earth. Only if we deform the flat earth until it is a globe we can get all distances right."

LOL!

The whole "Problems" section is like this. It lists all the problems with the model and then states that the problem is solved with the heliocentric globe earth model. I think this guy created this model in an honest attempt to make a working FE model to show that there isn't one.

That's why they never include a scale on their map.

I was taught in Geography classes that a map without a scale is not a map. Obviously not an absolute truth, but more a reminder to meet certain standards of cartography, or be written off as a cartoonist. (Nothing against cartoonists, they used to draw great sea monsters towards the edge of a flat Earth.)

So here's a super crude image of what I was trying to describe. The observer is in, say, Quito, Ecuador. At noon, during the equinox, observer can see the sun due East at about 6 AM, directly overhead at about noon, and due West at about 6 PM.

Sunrise and sunset times in Quito

That kind of reminds me of Gene Ray's Timecube diagram.

I hope they also taught you in Geography classes that on each type of map, the validity of the scale has to be explained.

There is no - repeat: NO! - length-preserving projection from a sphere to a plane. You can get projections that are length-preserving for certain lines, but not overall.

This fact alone is a surefire hint that the earth is not flat.

If one lives on the equator it is always 12 hours of sunlight & 12 of night. For comparison, consider the planet Mercury-it's year arrives before its day. In fact the sun just moves from a point just above the horizon to its corresponding point across.

Yes. But it doesn't always rise and set due east and due west.

Mercator, Mollweide (?) equal area, Lambert conical, Azimuthal, Cylindrical. The whole shebang.

Try adding in the complications of a third dimension when you are calculating anti-collision trajectories for for drilling a well in a field laced with other wells.

This is the strange thing about cartography how to design a map that reflects proper geometry.

It's only strange when you try to map a sphere on a flat surface. Works fine on a globe.
