A Friendly Challenge

submitted by CHIRO to EarthIsAFlatPlane 2.9 yearsJun 2, 2022 19:36:39 ago (+6/-1)     (EarthIsAFlatPlane)

I have an algorithm I believe will prove to any flat-Earther that they're wrong (referring to proof within reasonable limits, and not mathematically formal proof).

1. Select a meridian line of the Earth where simultaneous observations can be made by two individuals (or instruments), where one is located on the meridian in the northern hemisphere between 30-60 degrees latitude, and the other is located on the same meridian in the southern hemisphere between 30-60 deg latitude. Try to locate them on the same latitude line - as closely as possible - for their respective hemispheres.

2. Place a camera at these locations (a human can operate the camera or they may be automated). The cameras should be identical, wide-field, and they should be oriented at the same angle with respect to the ground to capture the night sky directly overhead.

3. Take a picture with both cameras at midnight.

4. Compare photographs.

5. Realize that the night sky is different at the two locations.

6. Prove that the surface of the Earth is curved.

The reason this will work is based on simple math.

The choice to use an identical meridian line is not affected a priori by the roundness or flatness of the world, and would work in principle whether either was the case.

If the photos have different features in the night sky, the only possible explanation is that the Earth is curved. That is because if they are different, it can only mean that each camera is on a unique tangent line to the Earth's surface.

The only thing that can have multiple non-trivial tangent lines is a curve.

The degree of overlap between the two photos should decrease with increasing curvature.

P1. If the Earth is flat, very different photos should not be possible.
P2. Very different photos are possible.
C. Earth is not flat.

If this is explainable under Flat Earth, please educate me.

EDIT: including a couple diagrams to communicate the hypothesis visually

Bro, they're not sincere. They're not going to test anything to make sure.

[ - ] gat 2 points 2.9 yearsJun 2, 2022 21:56:42 ago (+2/-0)

I have to disagree. Those I've interacted with are sincere and looking for answers. It's literally the other way around in 99% of my experiences. And many tests have been done, how can you make the claim they haven't? It's all about testing. Some religious nutters may take it on faith, but I've not met any that don't make testing top priority.

Don't worry I can see that a mile away. (Just not 2 miles, due to the curvature of the earth)

Keep it simple:

1. Point them at https://www.suncalc.org/
2. Point out this accurately predicts the motion of the sun, anywhere on the planet, on any day, at any time
3. Challenge them to explain how that can work, if it's based on a false premise
4. Challenge them to produce something that works better, based on a flat model

Steps 2-4 optional. Feel free to just drop the link and observe the cope gymnastics that follow.

Step 5: ignore the fact that it works under both models but one model gets billions of Marxist/kike dollars spent on promoting it, at the taxpayers expense of course.

[ - ] GloryBeckons 3 points 2.9 yearsJun 2, 2022 20:45:22 ago (+3/-0)

Show me a flat model that can do this then, if it "works" under both.

Doesn't need to be pretty. Doesn't need to do anything fancy. Doesn't even need graphics. Anything that can make any kind of accurate predictions about where in the sky the Sun should be would be fine. Hell, even just predicting sunrise and sunset time, down to the minute, would be a good start.

The math should be much simpler, if the Earth is flat and the Sun just flies in circles above it. So what's the problem?

[ - ] GatekeepingFaggots 1 point 2.9 yearsJun 2, 2022 20:59:40 ago (+3/-2)

Do you expect me to whip up a fancy calculator like the one you linked? We have an app that millions of us are using which has all of this, other then that the only thing I can do is give you videos on the subject until someone spends the money to develop a web based calculator.

And a video showing southern star trails.

Unlike globetards who accept the textbook narratives they were fed and now regurgitate, Flat Earthers are actually interested in conducting their own experiments to figure out the world around us.

[ - ] GloryBeckons 2 points 2.9 yearsJun 2, 2022 23:40:13 ago (+2/-0)

I specifically said it doesn't need to be fancy. Just make accurate predictions. Even something as basic as sunrise and sunset.

Ah, yes, the magic sunlight video. With obligatory emotional music overlay.

A model where our Sun's light behaves completely differently from any other light we've ever observed, traveling along arbitrary asymmetric paths, which ignore the density of the medium they're traveling through, in order to force them to land on only half of the "earth plane", and at very specific angles. Which all just so happens to mimic exactly the paths and angles you would expect to see... if the Earth was a globe and the Sun's light behaved like all other light in the universe. What a coincidence.

I've yet to come across any attempts to explain or justify why the Sun's light should behave so strangely, almost as if it is trying to trick us into concluding the Earth is a globe. But, of course, if it behaved like normal light, then the model would fall apart, because the whole plane would be illuminated all the time, and none of the angles would match observable reality. And we can't have that, can we. So... super duper special magic sunlight must be it.

The second video appears to be a confused old man rambling and mumbling under his breath. Not sure what the point here is. Also overlayed with emotional music though. Time by Hans Zimmer, I believe. Nice music. Easy on the ears. But I'm not sure what it's doing in this video. Actually, we all know exactly what it's doing there, don't we?

But I'm not sure what it's doing in this video. Actually, we all know exactly what it's doing there, don't we?

I guess the greatest story never told about Hitler was also propaganda considering it was full of emotional soundtracks, that must have been what convinced people to become pro Hitler according to your retarded logic.

Ah yes, dismiss the evidence and ramble on another tangent about retarded fantasy globe theory. None of your physics works on a flat plane model, we reject gravity and space and all the pseudo gibberish that you people were taught to regurgitate through school. You can not fathom how the sun works on flat plane model because you think like a globie. You have been tainted with garbage mate.

[ - ] GloryBeckons 1 point 2.9 yearsJun 3, 2022 00:30:03 ago (+1/-0)

TGSNT -is- propaganda. Which is fine by me. Not all propaganda is false. And it is meant to inspire emotion.

The difference is that it doesn't pretend to be presenting or defending a scientific model. There's no place for emotion in science. And you are clearly quite emotional about your flat earth belief system.

Here's what it comes down to, friend, very simply:

A model of how something works, which fails to produce anything usable or useful, is, by definition, useless.

Have your faith. Believe what you like. Put posters on your walls, wear t-shirts proclaiming your fandom. Whatever floats your boat. But stop insisting that's science, or that believing useless things makes you smart. It's not, and it doesn't. Anyone can watch a youtube video with some half-baked sci-fi fantasy theory and decide to become a believer. It takes zero effort or ability. It doesn't make you special. Not the way you think, anyway.

The amount of gas lighting, deflection, ignorance of your own Globe model, dumbass science garble you regurgitate using science and maths that you can't even comprehend.

I hate to think that one day you are going to wake up to the truth because I genuinely hope you stay globetarded.

Pilots would have noticed soemthing by now, making flights spanning large arcs of the earth’s surface. Pilots would all have to be “in on it”

[ - ] gat 0 points 2.9 yearsJun 2, 2022 22:07:49 ago (+1/-1)

Many pilots have come forward. Some have been fired for doing so. Whenever you fly, try to ask the pilots what they think. The horizon is always level no matter how high you go. Hard to deny that and many pilots won't.

I refute your argument based on biased opinions on how things should appear to a human in respective to the sky in general.

The premise of your arguement is based on accepted science and is therefore:

Fake and Gay

I'm fairly familiar with the Flat Earth stuff, though I'm no expert. I've watched or listened to Dubay's material.

Neither his nor ancient systems denied the existence of fixed stars, nor did they say we couldn't see them.

I don't know anybody denying that. All my experiment requires is looking up at the stars and capturing a pic.

I should be clear I find Flat Earth interesting. I am not aggressively against the theory or the people who endorse it.

I'm a bigger fan of being authentic to where my reasoning leads me, so I am also committed to poking holes in it if that is possible.

[ - ] FacelessOne 2 points 2.9 yearsJun 2, 2022 20:13:00 ago (+2/-0)

First off, they are known as the Luminaries, if the atmosphere has pockets of frozen bubbles could you really tell the difference?

[ - ] FreeinTX 3 points 2.9 yearsJun 2, 2022 19:52:20 ago (+3/-0)

Prove the Earth is round.

Sun goes down in LA. Few hours later comes up in Tokyo. Rinse. repeat.

[ - ] CHIRO [op] 1 point 2.9 yearsJun 2, 2022 20:09:07 ago (+1/-0)

A curve implies roundness. So what I said in the OP would do the trick.

But if not flat, then something like a sphere is the alternative. Unless you are saying we live on the convex surface of a giant contact lens.

[ - ] FreeinTX 2 points 2.9 yearsJun 2, 2022 20:14:04 ago (+2/-0)

I'm not the OP. I was offering a more simple solution to proving the earth is round.

[ - ] CHIRO [op] 0 points 2.9 yearsJun 2, 2022 20:18:54 ago (+0/-0)

I thought when you said 'Prove Earth is round' you were directing that at me, haha. I was thinking: man, didn't I just try to do that by making this post?

Not sure what you're trying to prove. The night sky is different in 2 locations? That works for both models.

Let me know if I'm misunderstanding your test. Maybe add a diagram or sketch of what you propose.

Nice.. Thanks!! I think I understand what your going for.

Check this 20 min video. It explains crepuscular and anti crepuscular field of vision. Breaks it down and makes it easy to understand for sun and stars. Please let me know if this covers what you're asking.

That is an interesting video, but I'm afraid it doesn't cover my question. My challenge has nothing to do with the motion of the stars, but with which stars are visible at all.

The diagram in the 2nd picture is deceptive and doesn't properly represent the scale of difference between the two cameras. The two pictures would be different because the overlapping portion in the diagram would be infinitesimally smaller compared to the darker shaded region of non-overlapping portion.

That overlapping portion would also be far off near the horizon (on the southern horizon for the northern camera, and on the northern horizon for the southern camera)
