Flat Earth Theory / Re: What is agreed upon?
« on: March 24, 2020, 11:06:15 PM »
Because maps of the whole world are not necessary.

This is very interesting: because you have no need for them, no one should ever need them nor make them? Or just be curious enough to map it for the sake of science?

Wouldn't a map of the whole world be useful to discuss the shape of the world, which is, as far as I know, the raison d'ĂȘtre of this forum?

To represent all or part of the world. Do you mean a map can only be used to plan an itinerary? It's a very common use indeed, but certainly not the only one.
The only legitimate reason to use a map is to plan a trip.

Go tell, for example, weather forecasters or seismologists they have no business using a map.

A round earth is, by definition, not flat. To make a flat map of a world that's not flat, you need a transformation. This transformation is called a map projection. There are many different map projections, and which one you choose depends largely on what you want to do with it. None of them is really more wrong or more accurate than another - they are just different representations of the same thing.
Well, I would think when you guys come up with one that you guys agree upon, then it might be time for you guys to come demanding one we guys agree upon.

Has anyone "disagreed" with the Mercator projection used by Bing and Google Maps?

You fail to understand that there is not really a "tilt". The Moon appears exactly the way it's supposed to appear. You intuitively expect to be able to draw a straight line from the Moon to the position of the Sun in the sky, perpendicular to the terminator. But this expectation, albeit intuitive, is false. Because of perspective.
Actually, far be it from me to argue with one of my RE brethren, but actually the moon tilt illusion is, as the name suggests, an illusion.#
When you observe the effect you can stretch a piece of string from the moon, perpendicular to the terminator, and you'll see that contrary to the way it appears there is a straight line between the moon and sun

Indeed, by "straight line" I meant a line that appears straight on a 2d projection such as a photograph.

The important point being that there is no need to explain how a tilt happens, because there is no tilt - as you rightly said, it's just the illusion of a tilt.

Please show one of the entire world.
Why?

What is a legitimate purpose of a map?

To represent all or part of the world. Do you mean a map can only be used to plan an itinerary? It's a very common use indeed, but certainly not the only one.

In our case, we want to have a representation of the world. Making a flat map of a flat Earth should be extremely easy, even trivial. You'd just have to scale down the real thing. Why isn't there a map of the flat Earth that every FE'r agrees upon then?

Then compare the sizes of, say, Greenland vs Brazil, India, Australia. Or Svalbard vs Sri Lanka. Or Iceland vs Gabon. Let's see if it matches reality. If it does, let's see if there are other problems.
As if you have any

PERSONAL

idea of the shapes of any country.

You don't.

I was asking about sizes, not shapes. You can get a personal idea of the size of a country by travelling to this country.

As far as the OP is concerned, I already answered that question.

Nearly all flat earthers agree the earth is not a globe.

Wait - have you just written that some flat earthers don't agree on the very principle of a flat earth?
Yes, there are some flat earthers who don't agree on a flat earth, believing it to be concave at the edges.
No wonder it will be hard to agree on a map then.
As if RE agrees on a world map...

A round earth is, by definition, not flat. To make a flat map of a world that's not flat, you need a transformation. This transformation is called a map projection. There are many different map projections, and which one you choose depends largely on what you want to do with it.

We already have the math with the actual RE distances.

I agree that things should not turn much to persoective. The Moon would actually turn negligibly to perspective in RE, less than 2 degrees.

So how can you get it to turn 45 degrees to perspective, without seeing different sides of the Moon's day and night?

How can a pencil or a Rubix Cube tilt to perspective without seeing different sides of it?

You flatly refuse to answer.

You fail to understand that there is not really a "tilt". The Moon appears exactly the way it's supposed to appear. You intuitively expect to be able to draw a straight line from the Moon to the position of the Sun in the sky, perpendicular to the terminator. But this expectation, albeit intuitive, is false. Because of perspective.

How could we explain a tilt when it's not there?

167
The general response to this is to claim that the physical Moon is not tilting, but that it is only the Moon's day and night that tilts to perspective. This is also incorrect, for the same reasons previously discussed, since one would have to see different parts of the Moon's day and night:



The same issue occurs. The Moon Phase diagram I provided previously shows that different observers would have to be viewing different parts of the Full Moon.

The only thing your previous diagram shows is that you have not understood the round Earth model. As previously mentioned, the Moon appears to move in the sky mostly because of the Earth's rotation, not of its own movement : it orbits the Earth in about 4 weeks. The orbit of the Moon around the Earth is what causes phases.

For example, let's say the Moon is in M1. E8 E1 and E2 see a full quarter, E3 and E7 see a Moon that is rising or setting. As the Earth spins, everyone will see the Moon rise and set - but they will all see a first quarter, only slightly fuller as time goes by and the Moon moves on its orbit. The Moon is far enough for everyone to see the same side, but the orientation will depend on the latitude.

A few days later, the Moon is in M8, and the same happens : everyone sees a waxing gibbous rise and set. Etc.

The so-called "tilt" is not involved to explain the phases. It's not even really a tilt : just the illusion of a tilt.

Quote
So, how does this work with "extreme perspective" as the answer to this?

It's still just perspective. And it only has to account for the angle of the terminator, not the phases. I'm not sure what "extreme" perspective is, or if it even means anything, or if the word "extreme" is just there for dramatic effect. Maybe this video was already mentioned, but I think it explains quite well what is going on. Perspective can play some tricks on our brains.

168
The star map will look different depending on your latitude, and include different stars. Two good sites with star maps are https://staratlas.com/ and https://www.heavens-above.com/ . You can check their accuracy by comparing the night sky at your location with the data they provide.

I wish you the best of luck in your project, but I don't see how you could make that work with a flat earth and account for the fact we see different stars at different latitudes. I'd be very curious to see the final result.

169
So you have never seen a satellite cross the night sky?  In the exact position that it is supposed to be?
I don't know about exact position, but yes I have seen a satellite cross the sky.

In case you're interested: https://www.heavens-above.com/ will give you a list of satellites you can see in the sky for any date and any given location, including the ISS. You'll know the exact time and position in the sky.

170
The Moon tilt illusion is just that - an illusion. It happens because the Sun is much further away from us than the Moon.

You can get the exact same "tilt" on a Ping-Pong ball when the Moon is visible during the day : https://skyandtelescope.org/astronomy-resources/what-are-the-phases-of-the-moon/

The phases of the Moon, and its apparent movement, are perfectly explained in a round earth model. As well as the apparent movement of the rest of the night sky, which is almost identical. As well as the fact that we see different stars at different latitudes. I still have to see a flat earth model that could be compatible with what we see in the skies, let alone explain it.

Anyone can look at the lines on their monitor and clearly see the one depicted on the landmass of Norway is bent more than the one over the ME and Africa.

They can also clearly see they do not represent a linear shape over a flat surface of an x/y plane.
Correct. Because Google Maps, as you zoom out, correctly depicts the earth as a sphere. So over longer distances you will see lines bending.
Well, you weren't using a flat map then.

Why would you try and use a non-flat map to argue with me over flat maps?

So, we're back to the original point.

If Google Maps and Bing are not flat maps, and you finally realize they're a projection of a sphere in two dimensions... Please show us an actual, and accurate, map of the flat earth.

And if possible, to get back once again to the origin of this thread - agreed upon among flat earthers. According to the FAQ of TFES, such a thing does not exist. Why would it be so hard to make a flat map of a flat earth?
Allow me to clarify.

All maps that are presented on paper and utilize linear measures for scaling are accurate.

There are plenty of accurate flat maps like this.

Please show one of the entire world.

Then compare the sizes of, say, Greenland vs Brazil, India, Australia. Or Svalbard vs Sri Lanka. Or Iceland vs Gabon. Let's see if it matches reality. If it does, let's see if there are other problems.

Necessary to use the word "projection," to maintain the illusion of globe.
I see. So cartographers down the centuries are in on all this too, are they? The earth is flat, maps are flat. So it should be fairly simple to make an accurate map of the earth. But no. They decided to deliberately distort it for...reasons? And they made up a whole lot of different ways of doing so? Sheesh.
I doubt cartographers have any input as to the writing content placed on their end product...

Did Mercator or Piri Reis coin the word, "projection"?

Mercator, just like any scholar of his times, wrote in latin. Can you read latin? https://upload.wikimedia.org/wikipedia/commons/4/42/Mercator_1569_world_map_sheet_01.png

If not, well, maybe the translation in the Wikipedia article can help you understand: https://en.wikipedia.org/wiki/Mercator_1569_world_map#legend3
Can you read the post again and understand my question was quite specific and mentioned nothing of the language used, just specific words?

Thank you.

You didn't even read, did you?

I'm not sure if Mercator used the word "projection" or its translation in latin. But it's not very relevant, as he did write: "to spread on a plane the surface of the sphere". How do you call that in English? A projection.

All maps are flat for a reason.

The reason is: because paper is flat. And it's more convenient to print maps on flat paper than on anything else.

Quote
All flat maps are accurate to the point we have used them for 100's of years.

Because for most use cases, the distortion that results of the projection can be neglected. And for the rest of cases, people know the distances aren't really proportional.

176
I would be willing to buy a long range laser measuring device like a bosch GLR825 accuracy to1/25 of in.and some plumb bobs if anyone wants to see what happens.

I'm afraid it wouldn't be good enough. At such short distances, the expected difference would probably be within measurement errors margins, making the experiment inconclusive.

For RE, there is usually general agreement 8n all aspects. The earth is round, the earth revolves around the sun, gravity exists, etc. I've noticed that in FE, there are so many different models and theories. Ice wall, no ice wall, but an infinite plane, earth sits on the back of a giant turtle, Maturin(the giant turtle) stands on the back of four elephants, gravity does exists, gravity does not exist it's upward acceleration, etc. I guess what I'm wondering, is there anything - other than the earth being flat - that all flat earthers agree on?
There is a general agreement among flat earthers that the earth is not a globe.

Other than that, I am not sure.

This is not surprising. Agreeing on virtually anything else would be the first step towards accepting a single flat Earth model, in which it would be much easier to find impossibilities or inconsistencies, either within the model itself or between the model and observations that can be easily made in the world as we see it.

I mean, we don't even have a definitive map of what it's supposed to look like. Humans have been making maps for centuries, and no one could ever come up with a correct, definitive map of the Earth if it were flat?
I am not sure what you mean, as all maps are flat.

And all flat maps are very definitive.

It has been years since I have run across an inaccurate flat map.

You have heard about map projections, haven't you? All flat maps are somewhat inaccurate, but if the area that's mapped is small enough, it can be neglected.

There is no definitive map of the flat Earth. I'll quote the FAQ of this very site : "Here is picture of a proposed, but certainly not definitive, Flat Earth".

I think we can prove or disprove flat or round earth by measuring the distance between two objects,silos poles or cranes.The tops should be farther apart than the bottom.

In theory, yes.

In practice, it's not as easy as it sounds.

The Earth is very big, so you'll need your two objects to be a) very tall and b) very far apart. You'll obviously also need them to be perfectly vertical.

The towers of the Humber Bridge, in its day the longest in the world, are 155m tall and 1410m apart. Still, the difference is "only" 36mm between the top and the bottom. Good luck measuring on your own that with the required accuracy.

There are easier, more practical ways to show the Earth's curvature. However, be aware that no matter how you show it, someone can and will come up with ad hoc arguments to claim it's wrong.

180
I asked the same question regarding the Artemis Project but received little response.  Will FE just consider it another hoax?   

What did you expect? There already is massive evidence from about 65 years of space programs. Hundreds of humans have gone into space, and 24 of them walked on or orbited the Moon. Countless photographs of the Earth have been taken. Thousands of artificial satellites orbit the Earth, many of which can be seen with the naked eye at the exact position they're expected to be, including the ISS, which you can see as a bright spot with the naked eye, but you can also see its shape with a telescope. There are other satellites you cannot see, but you can tell are there, because GPS works, because satellite TV broadcast works, because satellite imagery of every square meter of the planet exist.

If all of this has been discarded as fake and was not considered sufficient proof, what could another mission possible add that would not be discarded as well? A convinced flat earther will just say it's fake no matter what.
