Title: Explain the Circular Equator
Post by: ThomasKenya on December 02, 2016, 08:05:42 AM
Hello Everyone,
I do NOT believe that the earth is flat, but would like to hear the other side. I am a Kenyan who has crossed the equator at several marked points. On the ground, the equator is a straight line (ignoring altitude or the curvature of the earth)

But supposing the earth was flat, the only way to explain the trajectory of the sun would be that the equator would have to be a circle on the flat ground.


If that were so, it would mean that there is a great variance between maps (which saw the equator as a straigh line) and the actual location  of the equator (and by extension all points) on the ground.

Why then am I able to use maps that were drawn long before GPS existed, and find that the GPS coordinates tally with those on the ground and with present day digital maps - as well as the old analogue ones?

Why are GPS maps useful for navigation - showing me exactly where I am?

Since GPS devices make errors of only a few meters, how possible is it that the current maps are deffective and we are not able to detect - using them or sextants or aerial surveys.

Why are you ignoring curvature in one case, but demanding that we explain curvature in the other?

In either model, the Equator is circular in shape.

You can plot your GPS co-ordinates on any map. It's just a question of your co-ordinate system.

Thanks for responding - even if not addressing the question. The equator on the ground as I have seen it is a straight line

But if it were circular, it means the maps have misrepresented it - and that the entire map is full of wrong points

How come then that the maps with the straight line equator, tally with the ground situation

Is that not sufficient proof that they are the real maps?

I hope some analytic mind will read this question and answer it - even if you dont

To put the question in another way,

If you draw ANY  map with a curved equator - and transpose it over the ground,  will the sun pass overhead in the same way it does over Mt. Kenya and the other equator points such as Maseno? I bet not - it cannot be both ways.

But if I were deluded, so that the points on the equator - as painted on the ground are actually a curved line on the ground, then the maps are wrong - how then do the longitudes and latitudes sill align perfectly to the ground?

I think what he is trying to say is that you can transpose reality onto any kind of map or coordinate system you want to. You can make a spiral staircase map if you were smart enough to.

Also, just because the equator is drawn as a straight line on the common projections, it obviously does not mean that the sun travels in a straight line. The Earth is apparently on a circular path, while rotating, around a stationary sun. Capturing that complicated motion in relation to any coordinate system is no easy task.

Either way, it looks like a straight line on the ground for the same reason people say you can't see the curvature of the horizon at ground level. We're just too small and the Earth is just too big.

You claim "you can transpose reality onto any kind of map or coordinate system you want to". But you forget that if the earth were flat, there never be any need to "transpose reality onto any kind of map or coordinate system".  A map of the flat earth would be just a small scale version of the earth.
It is simply because the earth is a globe that projections are needed.

You give only part of the story, and try to unnecessarily complicate matters by bringing the orbiting around the sun into the mix. This has very little to do with the path of o the sun across the sky during the day.

I think that ThomasKenya will attest that at either equinox, on the equator, the sun rises due east, travels in an arc till it is directly overhead at mid-day and finally sets due west.

Now, if you look at the sun's path on the "Ice-Wall" flat earth map, the sun would have to rise from exactly North East, be overhead at mid-day and finally set exactly North West.

The sun simply does not do this.

Of course, if we were to accept that light travels in straight lines[1], the sun could never rise from behind the horizon or set behind the horizon.


[1] There is a little bending due to refraction when from the light travels from space into the atmosphere.
      At sunrise of products sunset this makes the sun appear slightly higher - roughly 0.5° .

Not getting far is it? They do tend to ignore threads when there is no reasonable Flat Earth answer. I have tried numerous time to point out that Australia on the Flat Earth map is over twice the correct width.
That "correct width" comes from early maps (I have an 1855 map), current atlases, Google earth, GPS distances and my own measurement of parts of it.

All these sources are consistent with each other, but far from being in agreement with the Ice-Wall Flat Earth map.

In other words, I can categorically say that in this region, the Ice-Wall Flat Earth map is wrong.

You keep saying that, but you are being disingenuous. You KNOW that the Azimuthal equidistant projection doesn't show things in realistic proportions, just as no projection does. But the distances are correct if you understand how the "map" is plotted. You do understand. You are just a liar. You refuse to ever accept anything that goes against your (or your employers) narrative. You spread falsehoods and when called out you never have once adjusted your position.

To say only Flat Earthers refuse to accept logical alternatives to their worldview, then sir, kettle meet pot.

Of course I keep saying that. It's simply because it's true.
There is one simple fact that you and many other Flat Earthers simply will not face.
If the earth is flat then no projection is needed to produce a flat map. 
How many times do I have to re-iterate that same point? A flat map of a flat earth would simply be a small scale drawing of the earth.

In my opinion, and that of many others the simple measurements of the earth make it impossible to be flat.
Read and understand this post The dimensions of the Earth will not fit on a Flat Surface « on: February 05, 2016, 03:04:26 AM ». (http://forum.tfes.org/index.php?topic=4557.msg88728#msg88728)

If you disagree with the dimensions given in that post, would you please come up with your figures for the equatorial circumference and the distance for the equator to the North Pole.
I can come up with plenty of evidence that those dimensions have been well accepted for a long long time, though not to the current precision.
Ships navigators would not have been fooled with the gross differences we would see if the "Ice-Wall" map were correct.

I "understand how the 'map' is plotted" very well, thank you! I know that it is as you say a North Polar "Azimuthal Equidistant Projection" of the GLOBE and so it has the accepted distortions of a "projection of the Globe". Just learn and inwardly digest and believe that if it were indeed a Flat Earth map it would not have these distortions.

So, your claiming that "the distances are correct if you understand how the 'map' is plotted", would be absolutely untrue if the earth were flat.

Then you scurrilously claim "You do understand." Yes, I understand very well.
                then "You are just a liar." That is nothing short of slander! I do not lie!, though I may shout at times - like now.
                       This is the sort of attack that comes from so many Flat Earthers when they realise that they have no case.

                then "You refuse to ever accept anything that goes against your (or your employers) narrative." I have no employer and no "narrative" - whatever that means,
                        I do not speak for anybody else and what I say I firmly believe.
                        all I have is a position that is firmly based on evidence, history, on what I see around me and that fits with all the other little observations I see around me every day.

                Your claim that I "spread falsehoods". That is completely untrue and again libellous, what I write here and everywhere else what I honestly believe to be true,
                                                                              so I am not spreading and falsehoods.
          and finally "when called out you never have once adjusted your position." Please tell me where I have been called out and needed to "adjusted my position."
                        Now, I cannot deny that I may have made mistakes that needed correction. If you can point these out and if I accept your opinion on said mistakes I will apologise.

As I see it, the Flat Earth hypothesis can only be supported by claims such as yours that adherents to the Globe are lying or deceived and that the absolute evidence we see every day is all faked.

What about YOU coming up with evidence that shows that you model for the earth explains the observations we see. You could do worse than try to tackle:

even simple things like how the sun can rise almost in the South East here, yet at sunrise the sun on the Flat Earth model is closer to the North East of here.

In other words instead of attacking people and always being negative, start being positive coming up with some viable alternative, as yet I honestly do not see any plausible alternative to the Globe.

Maybe part of this is from living in the Southern Hemisphere and seeing so many failings it the flat earth explanations with my own eyes. I see that the Southern Hemisphere is just a sort of "mirror image" of the Northern Hemisphere and that there is just as much reason to believe that the South Pole is a real location as there is the North Pole. There is just as much reason that the stars rotate clockwise around the South Celestial Pole as to believe that the stars rotate anti-clockwise around the North Celestial Pole. In recognition of this Tom Bishop now supports the "Bipolar map", but in my opinion that just opes up another set of problems.

Make some effort to show that your login name, "TheTruthIsOnHere", is more than just an empty phrase - if The Truth Is On Here, show it to us.

Believe what you will, but retract your outlandish claims or you will have proved certainly that "The Truth Is not in YOU".

I'll leave your pot and kettle allusions alone, but you'd better not look in any mirrors.
 

There are probably numerous errors, but I have no more time to waste on this sort of stuff.

Yes, you would find it very painful to read, the truth sometimes hurts, at least others might see what type of person you are!

If I am not permitted to defend myself against libelous claims like "You are just a liar" and "You spread falsehoods" at least read this:
I do not lie, I am not employed by anyone and I am not trying to deceive anybody. I say what I honestly believe to be the truth.
I will gladly admit that "my saying it" does not make it true, and also that I can and do make mistakes, but I say what I believe to be fact based on evidence.

The whole point is, if the earth were flat, then a flat map would simply be a scale drawing on a flat sheet of the flat earth.
There would be none of the distortions that are unavoidable in representing the surface of a globe on a flat sheet.

So no, I do not admit that "the AEP isn't meant to show Australia in proportion to things in the northern hemisphere." It is presented as a map of the whole earth.

As far as I am concerned,
          TFES and the flat earth "movement" in general (see all the flat earth Youtube videos) all present the "Ice-Wall" map as a true and proper representation of the shape of the flat earth.
Some individual members do not accept that and propose
          the "BiPolar (0°,0°) centred Azimuthal Equidistant Projection (of the Globe I might stress!) - Tom Bishop, Sandokhan and probably others,
          a "Dual Flat Earth", with a North Polar AEP of the Northern Hemisphere on top and a South Polar AEP of the Southern Hemisphere underneath - JRoweSkeptic at least.
          there is a dish-shaped "model" on that I think sceptimatic (of The Flat Earth Society) supports.
    and I believe that John Davis is pushing for a "non-Euclidean" something.

But, you claim that "the AEP isn't meant to show Australia in proportion to things in the northern hemisphere."

So, what Flat Earth map is meant to show the whole southern hemisphere in proportion to things in the northern hemisphere? Out with it!

I will stress this simple fact. If the earth were really flat an accurate map of the earth would simply be a scale drawing of that flat surface. There is no way to escape that.
The only inaccuracy in the map would be the accepted measurement uncertainties because of its smaller size, just as in maps of the globe.

One of the points i made, that you choose to ignore, is this:
In my opinion, and that of many others the simple measurements of the earth make it impossible to be flat.

Yes, we do know this.  Do the rest of the Flat Earth crowd? 

I just don't understand why nobody has produced a FLAT map of the FLAT earth on a FLAT piece of paper, one that DOES show everything in proportion.  Oh, wait: it turns out I DO understand....

No he doesn't admit that. He keeps bringing up how the proportions of Australia don't work on the AEP. Eventhough, they most certainly do if you understand the coordinate system. That is him playing stupid just to make a low hanging fruit argument.

Flat Earthers can't come up with the map because they don't have the means to. Probably not a lot of experienced cartographers going to get funding to create a flat earth map.

You could totally transpose Earth onto a flat plain, but getting accurate distances is something that took thousands of years of expedition and exploration to get. The "Map" we see of the "globe" wasn't a knee jerk production by the heliocentrists produced to appease the skeptics. And even then, originally was just a transposition of the flat earth map everyone used before that.

Quite true, I definitely do not admit that "the AEP isn't meant to show Australia in proportion to things in the northern hemisphere".
Your claim that "the proportions of Australia don't work on the AEP. Even though, they most certainly do if you understand the coordinate system." is quite false.
If you think I am wrong, maybe you can show how you get the East-West and North-South dimensions of Australia from that map - with all your working.
Please remember that if you utilise the co-ordinate transformations done in producing that projection all you are doing is proving that the earth is a globe.

What you fail to realise is what I have been at pains to stress and TotesNotReptilian pointed out "is that if the earth is flat, there would be no need for distances and/or directions to be distorted. But flat earthers can't come up with a flat map that doesn't include these obvious distortions."

The measurements of the earth are well known, the continents have been surveyed with increasing accuracy for many centuries.
The surveys of the land areas are actual measurements done
         in the early days with physical devices like chains,
         then from around the 1960s using electronic means (Tellurometer) and
         finally laser and satellite methods.

My stressing Australia is simply because I live here and have driven over essentially all of it a number of times and would know if the map measurements were grossly in error.

But, the whole point that you refuse to face is that if the earth we flat, no "projection" would be needed.
The straight simple fact of the matter would be that a map would be simple a scale drawing of the full sized earth. Until you face that, you will be forever confused.

The only need for any changing scales in the east-west direction on the AEP map is that it is a projection of the globe, and that is a known and predictable distortion.

THE AEP ISN'T A FLAT EARTH MAP. IT IS A PROJECTION OF A GLOBE EARTH.

I also mentioned that maps existed long before the Earth was thought to be round. People traveled relatively reliably all over the world, using the stars and the rudimentary maps available at the time. There was no reason to ever transpose the map onto a globe, aside from the contemporary thought that the Earth was round. No one uses a globe to navigate, or the "flat" map based on the globe shape.

I never said it was a map that accurately represents the Earth. I gave some reasons as to why a flat earth map doesn't exist in my post. You glossed over them.

No, I didn't really gloss over them. What I said was that the measurements of the earth are known and have been known for centuries,
so there is no point sending out a team of "Flat Earth Surveyors" to measure it again.

The earth those surveyors were measuring was the real earth, the only earth we have. Now unless you claim that all those measuring the earth were frauds, what could be changed by a new set of measurements?

As far as I know, the measurements we have of the earth still agree with measurements of individual distances on the ground.
When I get route distances from my car navigator or from Google maps the distance always closely match not only posted distance but my car's odometer.
I know that this is true not only in Australia but all around Great Britain and Ireland.
And I assume that you and others have the same experience.

Maps of USA and Australia over a century old are certainly in good agreement with current maps.

I can't personally check distances on that US map, but I am confident that distances and co-ordinates agree with current maps and with distances I have measured.

Why do you expect that measurements made by FE surveyors might be different?

Yes, but from the earliest days of western exploration further afield than around the Atlantic, all navigators considered the earth a globe.
Many early navigators did take globes with them, not for detailed navigation, but to picture more easily where they were on the globe.

But saying "No one uses . . . . . the 'flat' map based on the globe shape" is completely untrue. All flat maps used for navigation are projections of the globe and long distance navigators know that.

Finally, the nautical mile was originally defined as the distance of one minute of arc of latitude at the equator and
           the geographical was originally defined as the distance of  one minute of arc of longitude at the equator.
The current definitions of these (which don't differ much from the original sizes) are one nautical mile = 1,855.325 m and one one geographic mile = 1855.3 m.

These make the distance from the equator to the north pole 90 x 60 x 1,855.325 m = 10,018,620 m or 10,019 km and
                                                   the circumference at the equator 360 x 60 x 1,855.3 m = 40,074,480 m or 40,074 km.
And I am sure that any competent long distance navigator would be horrified if you suggested otherwise!

But at least on the AEP map (the circumference at the equator) = 2 x π x (distance from the equator to the north pole) - it doesn't fit!.

As I have tried to point out numerous times, the known The dimensions of the Earth will not fit on a Flat Surface. (http://forum.tfes.org/index.php?topic=4557.msg93611#msg93611)
And all I get are responses denying that we know the dimensions of the earth and/or that the measurements were all done by these evil Freemason Geodetic Surveyors.

I asked a related question on a separate thread - without response. To those who believe in the flat circle map:

When the sun is over cancer, the day is 24 hours

When it is over Capricorn - which would be significantly longer (70% by my estimates) the day is 24 hours long.

How can this be if the speed of the sun does not change? How does the flat map retain the 24 hour cycle

Actually, your walls of text would be almost bearable, if they didn't look like pieced together ransom notes.

My part of the post you seem to bitching about is

Quite true, I definitely do not admit that "the AEP isn't meant to show Australia in proportion to things in the northern hemisphere".
Your claim that "the proportions of Australia don't work on the AEP. Even though, they most certainly do if you understand the coordinate system." is quite false.
If you think I am wrong, maybe you can show how you get the East-West and North-South dimensions of Australia from that map - with all your working.
Please remember that if you utilise the co-ordinate transformations done in producing that projection all you are doing is proving that the earth is a globe.

What you fail to realise is what I have been at pains to stress and TotesNotReptilian pointed out "is that if the earth is flat, there would be no need for distances and/or directions to be distorted. But flat earthers can't come up with a flat map that doesn't include these obvious distortions."

The measurements of the earth are well known, the continents have been surveyed with increasing accuracy for many centuries.
The surveys of the land areas are actual measurements done
         in the early days with physical devices like chains,
         then from around the 1960s using electronic means (Tellurometer) and
         finally laser and satellite methods.

My stressing Australia is simply because I live here and have driven over essentially all of it a number of times and would know if the map measurements were grossly in error.

But, the whole point that you refuse to face is that if the earth we flat, no "projection" would be needed.
The straight simple fact of the matter would be that a map would be simple a scale drawing of the full sized earth. Until you face that, you will be forever confused.

The only need for any changing scales in the east-west direction on the AEP map is that it is a projection of the globe, and that is a known and predictable distortion.

What is so wrong with that?

But, if you can suggest a better way to present the material, I'll see if I can take it on board.

Much better, you almost had it except for that rogue centered paragraph. Legibility is better, now work on your brevity.

There is no centred paragraph.
And, what material would you suggest I leave out?

Now, what about you explaining why the AEP, if it is a map of the Flat Earth map, should show any distortion?

I would never do that because I know the AEP is a projection based on a spherical earth. I also said in my previous posts why an official flat earth map probably doesn't exist. What else do you want from me?

Nothing!

I agree that "an official flat earth map probably doesn't exist". I have claimed many times that an accurate flat earth will never exist.
Little sayings like "You can't make a silk purse out of a sow's ear." and "you can't fit a square peg into a round hole" seem relevant.

And yet so many of the arguments involving the movements of the sun and moon, the non-existence of a South Pole, etc, etc seem implicitly based on the AEP map.

I have seen quite a few Flat Earthers claim that in a short time the Flat Earth Truth will take over the earth.
That seems a laughable proposition when Flat Earthers cannot even agree on where the continents are, how big they are or the distances between them.

This was known with reasonable accuracy back before Captain Cooks time and since then all we have done is filled in unknown places and greatly improved the accuracy.

So I guess you can offer nothing more, but you never did offer anything. You just pulled down theories without any credible alternatives and criticised formatting and presentation.

Though I see you have stopped being an earth shape agnostic to a fully fledged Flat Earther, I guess that's "progress".

Just a quick addition: it's surely trivial to show you can't directly map a flat earth onto a sphere and vice versa. A flat earth either has an edge (see ice wall) or is infinite. A sphere does not have an edge on the surface ( any direction you travel you eventually end up back where you started) and it's not infinite. How do you map an edge onto a sphere?

I think anyone who was making a flat earth map wouldn't try to use the sphere as a starting point.

Maybe not. Of course there is a huge amount of mapping information available but has at its base a spherical earth coordinate system. Such that any map can be directly pinpointed on the surface of the spherical earth. These maps are used for all sorts of purposes by different organisations with different sorts of geographic information. Millions of journeys are done using these maps.
If you can't map them onto a flat earth you've got a problem obviously!
