How the ancient Greeks knew the Earth was round...THE DEBATE IS OVER!

[link to youtu.be (secure)]

No one in "science" uses Eratosthenes method as a proof of a globe earth, because it only works in a 2D plane.

Place a third point out of alignment from the first 2 points, in a triangle formation, and the the "model" collapses to prove a globe.

Notice how Sagan only has two points on a single curved surface, that he bends from flat to curved like a cylinder (that is called a single-curved surface, as opposed to a globe which is called a double-curved surface).

The reason why he doesn't use a globe, such as a beach ball, to display his point is because Eratosthenes model actually suggests a near sun and a flat plane when you resolve for 3 points in 3D on a double curved surface.

If this is your evidence, then the debate is far from over.

The proof looks quite valid. Explain how a third data point would disprove the explanation.

It wouldn't. A third point would only work on a globe as the Sun is distant which IS what Eratosthenes used. Flerfs claim that the angles from the shadows on an assumed plane can be used to get the height of the Sun. Add a third point on a plane and then you don't get the angles intersecting at the same place. It doesn't work when you assume a flat plane.

The ancient Greeks are dead because they were dead wrong.

You were born in a prison, and those who live free on the outside don't want you to know you're in a prison, otherwise you'd try to escape.

That simple.
Did you understand ?

Erotosthanes already knew the earth was round......his measurement was simply to determine its size.....which is done very accurately that way....


Of course you can place a local sun in just the right spot so that 2 angle measurements will yield the correct result.....but then every1 else on earth would see the sun veering wildly off course..

This is proof that the Earth is in fact curved circularly along its latitude .....and that the sun is some great distance away.....


There is nowhere you can place a local sun over a flat surface and get the correct angles we see every day all over the earth.....

here is a to-scale cad model of flat earth......with markers along each line of latitude.....

at the winter solstice ...at the 60th parallel north.......millions of people in st petersburg russia.....oslo norway....and fairbanks alaske.....see the sun rise to 6.6 degrees above the horizon at noon......
while people at 60 degrees south see the sun at 53.4 degrees above the horizon.....

people at 45 degrees north see the sun rise to 21.6 degrees above the horizon.....while people at 45 degrees south see the sun at 68.4 degrees.......
of course .....these angles then reverse themselves at the summer solstice......


here is the flat earth side view of this situation.....every1 seeing the sun at all these different angles at the same moment......

while a spherical earth makes all observed angles line up precisely for every1 on a globe.....

And the shill returns…

I'm assuming a local sun 3100 miles up and about 31miles across.....over your flat earth Gleason map.....
This is as close as you can ever get to replicating what we actually see from 60 degrees north latitude to 60 degrees south latitude.....
Any other height and size will simply magnify the errors you already get....



There is nowhere you can put a local sun over a flat surface......with evenly divided latitudes ....that will replicate the angles we see the sun at on earth.....

For the same reason you can never get a sunset on flat earth due to perspective.....in order for the sun to get even 1 degree from the horizon.......the sun would need to be 178,000 miles away......while simultaneously being high overhead somewhere else on flat earth at noon.....



Here's an idea.....why don't you do as I've done.....and build a scale model of the flat earth disk.....then tell me where you put the sun to match the angles we see the sun at.....??

Isn't that like....the first thing you would do the day you decided to believe the earth is flat....??

Has it ever crossed your mind that there's a good reason nobody has produced such a simple working model of flat earth that can definitively triangulate the location of the sun and its path around your flat diskworld.....???

The debate will never be over, because it is too amusing.

You don’t even need math to prove the earth is round. The moon is literally upside down in the Southern Hemisphere compared to the northern hemisphere.

The entire pattern you see on the moon is 100% upside down on each hemisphere from our perspective.

That is because the Sun doesn't really exist.

Wave particles hit the magnetosphere, generated by the dynamo inside disc world, causing light from other stars to hit it*, and they pool together in a way to create the illusion of a spherical ball in the sky that behaves as though the Earth rotates around it.











*ignore the logical fallacy, I want to see if this catches on and I'm annoyed your trying to end the debate. There are only a few pleasures in life, and flat Earth vs Globe Earth is one of them. It isn't about the destination it is about the ride).

That would only prove that the human brain is designed to perceive the world as if it is flat.

Flat earth tards: "the horizon looks flat to me bruh....dont you believe your own eyes..??!!"


Also Flat Earth tards: "everything you think you see in the sky is a magic hologram engineered to fool you into thinking the earth is a globe...!!"

No.

Go do the math yourself.

Plot three points on a globe, and the reality we see only matches a near sun on a flat plane. Even if you can't be bothered doing the math, a beach ball and strong torch can display the concept easily.

Once you add a third point on a globe model, by triangulation, it disproves a distant sun, and near sun with three points only works with a flat plane, to resolve Eratosthenes math.

Again, as I said, this why this model is NOT used in science as a proof of the size and shape of the earth.

Eratosthenes model only works with 2 points and a distant sun. Add a third point and model collapses, the math suggesting a near sun, by triangulation.

In the end, it's all mathematical model guesses. We always seem to have to "trust" someone's word.

After the last 3 years I don't trust ANY voice of "authority" anymore.

Especially now with rabid globers (people who seem to actually care about the earth being a globe or not), who have nothing better to do with their time than be rude.

To really prove it one way or another, we would have to go to places, simultaneously, that the powers don't allow for.

Why is that?... and doesn't that suggest we SHOULD be asking this question?

This actually doesn't prove anything.

As most Flat Earthers believe the sun to be much smaller and localised on part of the flat plane.

So it could in fact be above one and make the other cast a shadow.

I did the math and posted it above.....

Works perfectly on a spherical earth with a distant sun.....

Produces absurd results for a flat earth with a local sun....

I only used locations from 60 degrees north to 60 degrees south.....where any1 is free to travel and document their observations ....

Feel free to do the math yourself and tell me where to place a local sun over a flat earth.....

You have no idea what you’re talking about.

Brilliant counter argument....

It's about par for most of the people who argue with you about the shape of the Earth.

Perhaps when they get around to addressing your points, they might also provide an accurate flat map of the flat Earth.

Hope springs eternal.

Really stupid people like to think they're really clever.
Even worse than the FE is "We live inside the Hollow Earth."
Dumb beyond belief.

No, NO, no more debating people.

OP Knows whats best for us.

No questioning science or its off to prison for anyone that does (and yes, the Democrats have a bill going through Congress to make "questioning science" a jailable offence)

And exactly what bill would that be...?

Flat Earth is curved like a mushroom. Creates a measurement illusion that the Earth is spherical.

how they know the right time to measure the shadow?, the had instant comunication across distances?
The earth is nof flat as a table, is rugged with the base flat, as the planet in "No Game No Life" or Signals(not the Mel Gibbson movie, another) and we are the ants

The north star. It never moves. But we live on a spinning ball? lololol

Whos stupid now you little shitty ass peasants? Suck on my fake ding dong rocket bitches.
