Flat Earth Theory -vs- Round Earth Theory

Yeah, I understand your point. But I can’t really help out with your creationists issue, (I’ve tried my hardist). Racialists… I mean, nobody can help that. Climate change deniers? They deny it 99% of the time because they’re creationists. So, I have decided to use my worthless life to make people who think the world is flat realize they’re purposely being ignorant.

I always thought the Flat Earth Society was some sort of joke organization whose members were just having a lark.

But I do have a question along these lines, and this seems like a good place to pose it. I’ve read that people in the past never did really believe the Earth was flat. From shore, they could see ships disappearing over the horizon, with their masts the last to go among other evidence. But then I’ve also read that Columbus had difficulty finding a crew, because everyone was afraid of sailing off the edge of the world. So was it a case of just the lower orders being overly superstitious, or is the Columbus story bogus?

Lower orders being overly superstitious, as it is in modern times.

But no, they’re dead freaking serious. It’s not that they’re really good at messing with people, A LOT of the members REALLY believe it.

Not exactly, the point IMHO is that you have to post for the lurkers that are looking for good information, and there is a lot to be done out there, I’m involved in real world politics too, not just message boards; the idea is not to convince willful ignorant to change, but to make efforts to prevent followers of woo woo to get into positions of power.

Other ignorant ideas get traction in many areas, but when Flat Earters get in the news it is only to make fun of them.

Alrighty then! Thanks for clearing that up. I suppose I’ll just leave it alone then.

I want to put it out there that I am not a Flat Earther. I’m just going to play Devil’s Advocate here to point out the futility of arguing logically with someone who has not used logic to arrive at their conclusions.

To be fair, you can Photoshop damn near anything nowadays.

They have an amusing theory here: The Sun shines not omnidirectionally, but like a spotlight with a fixed diameter beam. The Sun then hovers above the earth, shining downwards and moving in a circle above the earth, creating the illusion of a spinning sphere. In the Northern Hemisphere summer, it’s a smaller circle, near the North Pole. In the winter, it’s a larger circle, further from the pole. GIGObuster’s link has pictures.

Have you seen a lunar eclipse? With an unaided eye, it mostly looks like the moon gets redder, then darker, kind of from one side to the other. It’s nothing like the bright, sharp line that you see when in a solar eclipse.
How they explain GPS, or how round-the-world yacht races cut closer to the South Pole to shave off miles, I don’t know.

It may not settle the matter but I find this historical incident to be interesting:

Well, show a Flat Earther that, and it was forged. But yeah, that, as well as any other good point brought up in this topic, disproves their ideaology.

Yes, and the originator of the bogus tale was Washington Irving:

So yeah, If America had been not there, then we would not had heard much about Columbus. Columbus problem was to convince enough people that his numbers were correct.

Bogus. The sailors were afraid of the unknown. Unknown oceans; inability to find provisions; etc. Among other scary “omens,” they apparently passed Tenerife while one of its volcanoes was erupting.

Note that the seamen were correct in a sense. Columbus had vastly underestimated the distance to the East Indies, and all the seamen would have died at sea, had they not stumbled upon a “new” continent.

Whoops, I forgot the link there:

I’ve only seen one and it wasn’t total. I could-- or at least I think I did-- see a curved shadow on the moon.

Sort of like in this overly dramatic YouTube video around 0:40 or thereabouts.

Yeah, sorta, kinda. I’ve seen 'em too. But it’s not so undeniably apparent that a Flat-Earther won’t deny it entirely. How exactly they explain lunar eclipses in the first place is less clear.

EDIT: Here’s the entry for lunar eclipses in its entirety:
“The lunar eclipse is an astronomical phenomenon which has several explanations.”

I’m sure there’s some truth in it. I don’t believe in ghosts, but there’s no way You could convince Me to spend a night in a ‘haunted’ house. I don’t want to see that I was wrong, especially if that means I’ll die.

I love FAQ question #1 “Is this site a joke?”

There was a time when people, even the most advanced thinkers of their culture, believed that the Earth was flat. Certainly the Greek presocratic philosophers Anaximander and Anaximenes (6th century BC) believed it, and I think there is evidence that the ancient Egyptians and Mesopotamians did too. The Greeks seem to have discovered the sphericity of the Earth some time during the 5th century BC. The most likely discoverer was the (later) presocratic philosopher Parmenides (although it may have been some contemporary or near contemporary of his) and the crucial evidence was probably the shape of the Earth’s shadow during an eclipse. The evidence of ships that disappear over the horizon does not seem to have been enough to clinch it; this phenomenon, after all, would have been familiar to Anaximander and Anaximenes, who lived in a maritime culture, in a costal city.

At any rate, Aristotle, in the 4th century BC, clearly regards the sphericity of the Earth as a well established, well known fact, and once Aristotle had written it down, it passed on to future eras of western (and Muslim) culture.

That’s grand. The link you gave was to phases of the moon, though. Here’s the lunar eclipse one: The Flat Earth Society Wiki | HomePage

You can use the method of Eratosthenes (~250 BC): just take a stick, and measure the length of its shadow at the same time in different places.

Or, use Foucault’s pendulum: on different latitudes, its plane of oscillation will change with different speeds; in particular, on the equator, it will not change at all, while at the poles, it will rotate once in 24 hrs.

Yes, but normally you hear blather about Columbus having proved the Earth was not flat, those ancient discoveries of the world’s sphericity having been forgotten during the Middle Ages. No doubt some benighted souls believed all manner of nonsense about falling off the edge, but I would guess most people in Columbus’ day would have scoffed at that.

If you go high enough in a plane or maybe even a mountain can’t you begin to see the curvature of the Earth?
