Stanley has been dodgy this whole thread.  He's dishonest.

FE proponents haven't explained yet, how the sun disappears below the horizon at sunset, and reappears at sunrise. How is it possible, that the whole flat earth isn't dark after sunset and before sunrise?

They think the sun and moon circle above a flat plane and disappear due to "perspective".

You're free to do what you want, but I think there are easier things to probe.

My answer: FE theory doesn't even explain the most basic phenomena. In my eyes FE is simply hilarious.

The most basic phenomena I would like to see explained at the same time are days and seasons.

We're getting close to the solstice. In Stanley, Falkland Islands the sun rose at 4:32 am and will set at 9:12 pm today, a 16 hr 40 minute day. Yet it was night the whole time in Barrow Alaska, no sunrise or sunset today.

While the sun is illuminating places in the southern hemisphere for well over half the day, at least part of the arctic circle gets no sun.

This is easily explained by a globe with a tilt. How does "FE" explain this?

One would need multiple flat earthers at distant locations who trust each other. There are plenty here on CI.

But are they ready?

I wasn't presenting my observations to provide proof for globe earth to others. Rather I just was telling Tradman, who said ...

... that I personally verified that I can see further from higher up. The whole bay is very quiet, a few meters deep only, more like a lagoon. You need a storm to get higher waves.

I managed to convince my wife, who has seen that island for more than two decades every day with her own eyes. We can see it from higher up, but not from down below. We also see small boats, which don't disappear behind waves. And we've cruised the bay in small boats.

That's why we're convinced that the surface of the water in the bay is curved, not flat.

Marion, can you replicate the curve of the water in the bay on a smaller scale?

Consider a bucket of water that is half full.  Tilt the bucket to the side.

Does the water curve?

This part of your statement I agree with.  There would be an obvious visible curve at that scale.

Yep.  And Stanley, who has labeled himself as an aviation expert, has dodged this question now MULTIPLE times.

How do you suggest to measure the curvature/flatness of the water in the bucket?

For the 120m rail I calculated 1.12mm deviation from a straight line. For a 50cm bucket, that's less than 20 micrometers in first linear estimate. Probably really even less than 1 micrometer. I wouldn't know how to ensure that  all sorts of effects and imprecisions can be excluded.

Dave Weiss has videos that explain the seasons pretty well.

Pfft.  The seasons don't make sense on a GLOBE.  This 23.4 degee tilt (90 degrees - 23.4 = 66.6) doesn't come close to explaining season when the sun is allegedly 93 million miles away.  And especially cannot explain the radical difference between the environment of the North Pole vs. Antarctica, nor the fact that the "midnight sun" phenomenon is totally different where it should be the same.  Look at the jetstreams on a globe and they look ridiculous, but you flatten them out onto a flat earth map (based on Azimuthal equidistant projection) and suddenly they're in nearly-perfect circles.  Southern Hemisphere flight plans are a joke on globe earth, but make perfect sense on a flat map.  In fact, with flight tracker, they don't actually track planes in the Souther Hemisphere, magically dropping them from the map as soon as they leave the land.  Evidently GPS does't work in the Southern Hemisphere.  This goes on for hours.

Hundreds of videos thoroughly docuмented, with maps and measurements taken, showing that we see much farther than  you should be able to on a globe, even taking readings to calculate refraction ... compared to an isolated picture here or there from a glober that doesn't indicate the distance from the object, the equipment used, and where no attempt is made to zoom in.  Lots of deliberately deceptive videos, including that proven fake from PBS / Discover.

Airy's Failure and Michelson Morley proved that the earth does not move, but that the stars move around it.

Atmosphere could not stay on the planet adjacent to the nearly-perfect vacuum of space.  Only a container could explain this; gravity cannot.

Hot spots above the clouds from a sun 93 million miles away.

Luncar eclipses during the day.

We're supposed to believe that the rotation of the moon is synchronized to the second with its revolution around the earth, thus explaining why we have seen the same face of the moon for centuries.  Even if it were a second off, it would have changed over the years.

Eclipses happen because the sun is exactly 400x the size of the moon and also exactly 400x more distant.

Mountains photographed from nearly 300 miles away.  In fact, the record long distance photograph was of an island with a lighthouse that was only 125 feet above the sea level (including the lighthouse) ... from nearly 300 miles away, where it should have been hidden by many miles.

It gets ridiculouser and ridiculouser the more you look.
