You seem to be conflating two things there: visible curve and dip of the horizon, neither of which can really be 'seen' from low elevations - ie, reliably detected with the naked eye - though horizon dip can be measured, from just a few hundred feet or so with something like a theodolite; and...

It would be difficult fitting it on the screen. If we assume the hypothetical 3000-mile high sun - correct at 47.6°N - then at 80°N the distance to the equator would be just over 17,000 miles, rather than the 5,500-mile distance we rather inconveniently observe in reality. Worse, by the time we...

Yep. Their results are in the video at 4:24. The more southerly one's sum total of latitude and elevation is 90.83, while the other's is 89.5. Small errors, but enough to have their lines diverging rather than intersecting.

Lol. I don't think they did. I guess that maybe casts a sliver of doubt on the flat earth theory. There's actually quite a simple way to complete the picture, given that we know: At the time of the equinox, the sum of the degree of latitude and the sun's elevation angle equals 90 The distance...

The readings match suncalc, etc pretty well. What about the reading at about 14°N? And, of course, the one that someone on the equator would have taken? Plus, the sun you've drawn there to cover all the lines has a diameter of about 340 miles - over ten times the size a 3000-mile high sun...

Sorry, I was woefully off with that - obviously, wherever two different lines intersect, that must be a sun. So a more accurate picture of where the sun is on the flat earth is something like: Now, maybe we can safely assume that people in the southern hemisphere are always wrong about...

Approximately true, for the northern hemisphere. And another one in the south. Plus, had there been observers at 40-50°S we can tell there would be another one, as the angles are mirrored. So that's four suns, just for starters, at two different altitudes. :)

Can we be sure that they're perfectly level? Also, doesn't really look like there's much horizon on show. Plus may run into the problem I found in my post above, where not being aligned properly causes the results to be skewed. [Edit after thread move:] Just a few minor problems with that: the...

But what is that showing? It just looks like a bit of sea to me. How does it prove that the earth isn't flat?

Lol. That's HILARIOUS! (Another rating button I would use - for beyond funny.) I hope you noticed that I removed ONE of them yesterday. :p (I also wish all the smileys were yellow. I'd use the grinning green guy more if they were. But maybe I'm just showing my age. ;) )

Interesting to discover this thread: I'd been thinking about additions to the ratings system and I see they've already been mentioned here ("facepalm", "bad spelling", "vague"). I also didn't realise that the system was intended to lack negative-sounding ratings - I've always considered...

Maybe like others, I was curious to know what an "Aircraft Accident Package" is. Found some details in an FAA (Federal Aviation Authority) document. I'm not sure if others are being thrown off by the word 'package' - I know I initially was, never having come across this before - but it's...

A thread debunking the claim that Heather Heyer was not actually hit by the car can be found here: www.metabunk.org/debunked-charlotteville-victim-heather-heyer-was-not-hit-by-the-car.t9121/

An equatorial bulge is a difference between the equatorial and polar diameters of a planet, due to the force exerted by its rotation. A rotating body tends to form an oblate spheroid rather than a sphere. The Earth has an equatorial bulge of 42.77 km; this bulge is created by the greater...

Because you're not quite getting it, even though it's been explained to you many times over, and all the required information is right there in the thread (which you don't seem to have read closely enough). (I do understand and sympathise that language is an issue.) My suggestion is for one...

Not really. We already know that, as the same calculation was done in the very first post, with the same result. Nobody is disputing this figure, nor the formula for it. The question you're being asked is:

There's a thread on here dealing with that question - common misunderstanding. https://www.metabunk.org/explained-flat-earth-theory-why-don’t-our-clocks-have-to-change-by-12-hours-in-6-months.t7193/ Your 'answer' to Trailblazer mentioned something to do with the ocean floors - which I presumed...

Right. You keep saying that, and no one's disagreeing with you - that's all accepted, and isn't a problem. But I presume there's a point?

I think you're overcomplicating matters. All relevant explanations are in the thread already, so maybe having another read through may clear things up. Also, I'm not really sure why you think "ocean floor" would be relevant - unless you mean "ocean surface" (i.e., "sea level"). PS I fully...
