Circumnavigation of Antarctica disproves the flat earth
« on: May 01, 2024, 01:17:26 PM »
If circumnavigating Antarctica (or the south pole) one must constantly turn your craft towards the ice, just like when doing so for the north pole.  If what we think is Antarctica was actually an ice barrier around the permitter of the flat earth than to circumnavigate it one would have to constantly turn your craft away from the ice and of course it would take a much longer time.  But that is not what we experience.  Ergo the earth is not flat.

Have you actually checked this? If so, what did you use to determine which way to turn?
At this scale, I don't know of a single form of dead reckoning that would be accurate enough.

For the FE, at 60 degrees south, that is equivalent to a circle with a radius of 16 666 km. That is a circumference of 104720 km.
That equates to a degree every 291 km. Do you have dead reckoning that accurate, in water which is pushing you around?

For the RE, it is harder because of the angle. But taking a lazy approach, 60 degrees south is a circle with a radius of 3186 km, giving 1 degree every 56 km. Still quite difficult to achieve, and as said, now at an angle making it harder.

An easier option would be to use the south celestial pole.

It would not have to be 1 degree at a time, you could continue straight and then make larger corrections.  It could also be by air as well as sea.  In any case the "being on the inside" when traveling near or around the southern pole has never been reported as far as I can tell and it seems like it would be pretty obviously not what was expected.  As well of course of having the circumnavigation taking vastly longer than expected.

The issue isn't how much you turn or when, it is how you maintain the course.
Can you construct a straight line for 56 km? If so, how? What are you doing to maintain this heading?
You cannot use a compass of any form, as that that would allow you to continually correct your course without needing to account for the turns. e.g. a compass heading east would just mean you go in the circle without any specific correction.

If you would like a simple test, and have access to a large open area, take a car out to the middle and mark your position, then aim in a particular direction and mark something off in the distance in that direction.
Then cover up the windows of the car, and try driving slowly in that direction for some time. Feel free to use any inertial navigation unit to help.
Then stop, and see how well you went on a straight line. Even better if you film it from either your starting point or the intended destination.

You could also do it walking blindfolded.

How about multiple craft in a line in constant radar contact or celestial navigation?

If you are going to use celestial navigation, you have already gotten a round Earth, as that is based upon a round Earth and doesn't make sense for a FE.

For multiple craft in a line, are you suggesting having them encircling the pole?
If so, that would require a ridiculous amount of ships.
If not, you have the issue of keeping the craft in line, especially with currents.
And even ignoring that, there is still the issue of how accurate you can be.

If you have a spot on each craft 15 m above water level to see, then the horizon for it is roughly 14 km away, allowing a span of 28 km from one craft, to the horizon to a distant craft.

For that distance, you are looking at half a degree for the RE, and 0.10 degrees for the FE.
If you go to a more modest 5 m, then you get a span of 16 km and an angle of 0.28 degrees for the RE and 0.05 degrees for the FE.

Just to stay in line you would only need 3 ships which could be closer though you would have to have a protocol to manage how the line would be managed.  So perhaps not practical.  Of course there is always the much greater distance traveling around the perimeter of a flat earth would be compared to circling the antarctic.  Saildrone's (https://www.saildrone.com/news/unmanned-vehicle-completes-antarctica-circumnavigation) circumnavigation in 2019 even with all its wiggles clocked in at 22,000Km which is not nearly enough distance to have traveled around the edge of a FE.

While I suppose sailing around Antarctica would prove it did not form an ice wall as some crazy people think. it would be so much easier just to consult the admiralty charts required for such a hazardous voyage. These charts show exactly the nature of that particular landmass.

That's easy.  Set up a laser level and follow that line!

Isn't that what you are trying to do, go always east?  Then you could measure your distance traveled.  Globe earth a handful of thousands of miles and on a flat earth, many thousands of miles.  You don't need much precision in your measurement to distinguish the two.  Oh, assuming the military doesn't blow you out of the water.

The issue is that the closer they are, the more accurately you need to get that angle. But yes, I do not think it is practical.
Distance on the other hand works well.
A very big issue with the common FE map is that distances in the south are much to large.

That's easy.  Set up a laser level and follow that line!
The issue is how accurate is that laser? Including things like beam divergence.

Isn't that what you are trying to do, go always east?
Not quite.
We don't merely want to travel east. We want to do it in a way where we can tell if that is turning left or turning right.
Using something to determine which way is east and correcting for that wont allow us to determine that.

Then you could measure your distance traveled.
Yes, distance is a much better method.

Huh?
It is a test to show how hard it is to travel in a straight line.

For further corroboration, you could also consult Linda Blair who wrote the book on circumnavigating Antarctica by sailing, not once, but twice. I think her entire two trips were tracked by GPS. On the popular and spectacularly flawed flat earth model with ice ring wall, circumnavigation of Antarctica is impossible.

Watch videos of the huge wall of ice, not the part they always show of it, which is an outlying stretch of ice from it.

These videos show aerial views of the ice walls, which stretch out for hundreds of miles, in some of these clips.

They show something peculiar that isn’t seen in other coastlines over aerial views of such distances.

They show this wall of ice, hundreds of feet high, which is not found on ANY other coastline of our actual continents on Earth.

Because it is not a continent at all, nor is it a coastline of an actual continent.

Seen over a very long distance in aerial shots, it gently curves inward, not around lands of a continent’s coastline, jutting outward and back inward along it. 

Actual continents of Earth all have life, as originating on our continents, there’s no life on their made up ‘continent’.

They made maps of this great ice wall which encircles the Earth. They didn’t all make that a circle by some amazing coincidence! They saw the great ice wall around Earth, and mapped the wall around Earth back then.

We’ve flown directly over the continents, from one side or coast to the other side or coast.

We’ve flown over the oceans from one coast of continents to the coast of other continents.

Nobody can fly over their made up continent, it’s not one, it’s the ice wall around Earth.

This depends entirely upon what region you are looking at.

Have you ever been to Antartica?
I have a number of years ago on a wildlife photography trip.

There is no mystery about Antartica rather it’s something you need to support your delusional fiction.

You reject reality in favour of believing in a long list of fictions to support your own flat earth belief. The fiction relating to Antartica is just one of them.

Many thousands of tourists like myself go to Antarctica every year.
What you believe in is nonsense .

If you were really interested in finding out the truth you could Igo on one of these:-

The flat earthers fiction about Antartica clearly demonstrates their anti-truth stance and willingness to ignore the  truth at every opportunity.

They try to sell themselves as free thinkers only interested in getting to the heart of any matter. As with everything related to flat earth ideology the actual truth is very diffident with flat earth believers rejecting the truth at every turn in favour of their fiction.

For flat earth believers their flat earth fiction is all and they will perform any kind of mental gymnastics to distort the truth to hold on to their flat earth belief.

Antartica is one such required distortion. For their fictional belief to hold water Antartica has to form a wall around their fictional disc. Back in the day of their founder, Samuel Birley Rowbotham little was known about Antartica and the general population were relatively ignorant about the geography of that part of the world. As a result such claims about ice walls were difficult to challenge.

Tiurn the clock forward just under 200 years and the world is a very different place. Antartica has permanent scientific bases. Tourists visit during its summer months. Accurate maps exist of the continent. Images from space reveal its true nature and extent. There is no mystery. There is no conspiracy hiding its true nature….the truth is in plain sight.

Yet flat earthers require an ice wall to hang on to their belief. The truth for them is irrelevant what matters is the belief therefore the truth must be abandoned in favour of a  sub-fiction that helps to maintain and support their main fiction.

I myself have visited Antartica on a photographic tour several years ago, something that is open to anyone who has the time and money. It’s a big industry with several companies offering different types of adventures. These trips can only really take place during Antarctica’s summer months as the winter weather makes for dangerous conditions as the southern seas can be extremely hazardous.

Its not a case about circumnavigation disproving the flat earth it’s more a case of reality disproving it.

They had a great problem when they first tried forming the flat Earth maps into a ball, taking its center point as their North Pole of their ball was easy, then went downward with the map. This worked fairly well at the northern parts, less and less well further down to the far southern parts, that’s why ships were lost in southern seas so often with ball Earth maps used for navigation.

For many years, they didn’t put in any continent on maps, just patches in white color, all about that area. It was extremely difficult for them to figure out what to put in there, so they just put in some patches of land covered over by snow and ice.

When they later decided that area will be an entire continent about the size of America, that was never before known to exist, until the late 1800’s and later on, Admiral Peary claimed to have discovered it as an actual continent for sure, it wasn’t known before that point as a continent.

Then he described his several expeditions of this unknown continent over the years, where they went to various points along its coast. They didn’t explore much inside of it, nor had time for longer explorations of it.

What he then said, was not supposed to be told to us for awhile later, maybe years later.

He was on a tv show at the time. And he said that this recently discovered continent nobody knew existed before, and he’d already said he’d had several expeditions to it….

Was about the size of continental America!!!

Nothing more than a few explorations of it had taken place at that point, supposedly.That would be reasonable when it’s never been explored before then, a few initial expeditions, that is quite reasonable and logical to say by that point.

But when he said they knew it’s whole size, and that it was about the size of America, he really botched it all up. That would be completely impossible to have known by a few expeditions to it.

This happens all the time when it’s all a lie.
 
The truth is just told as it is, there’s nothing to put into it as made up, no sequence of lies to follow along it, that’s why people goof it up all the time, give different stories of it which conflict with each of the other stories,

That was one very obvious indication it was all made up to be told over time, in a logical sequence.

This would be like first exploring the coast of Florida and New Jersey over a few spots, and knowing it’s entire size of from just that!!

No, they had a great problem when they were trying to map large regions of Earth onto a flat surface. It simply didn't work.
But doing it on a round surface works fine.
That is why there is just one globe, yet countless flat projections, all of which distort something.

But that has nothing to do with the ability to navigate around Antarctica in far too little time for your FE fantasy.

When they later decided that area will be an entire continent about the size of America, that was never before known to exist, until the late 1800’s and later on
You mean when people later explored more?

Do you say the same things about Australia given it was only discovered by Europeans in 1606?
With the east coast only mapped in 1770?

Or do you only spout such crap for things which contradict your delusional fantasy?

What he then said, was not supposed to be told to us for awhile later, maybe years later.
Based on what?

He was on a tv show at the time.
At what time?
He died in 1920.
At that point television was still in its infancy.
Are you sure you aren't confusing that with Admiral Byrd?

But when he said they knew it’s whole size, and that it was about the size of America, he really botched it all up. That would be completely impossible to have known by a few expeditions to it.
Why?
If you go around the coastline you can easily get an idea of just how large something is.

The truth is just told as it is, there’s nothing to put into it as made up
No, that isn't a truth, that is your pathetic lie to reject reality which destroys your fantasy.

And again, if you want to claim people claimed things, provide a valid citation, because you are known to blatantly lie about what people said.

Except nobody had ever claimed to have circumnavigated it before Byrd said he knew its entire size!

That means it was ‘planned’ to be called a continent of that size already, but wasn’t supposed to be claimed yet, so when he said it’s size was about the size of America, he botched up, it’s ‘size’ was going to be ‘known’ later on, after many more ‘explorations’ had been done of it!

Many of the first maps of Earth  show a circular boundary around it, and Australia is shown on the left of the Americas, in various forms near the boundary, including the 1538 Mercator map which was his early attempt to revise flat Earth maps into a ball.

Note that it shows two separate halves of Earth, each of them bound by a circle.

He split the flat Earth map bounded in one whole circle, as two circles of half the Earth, and both maps have a large stretched out land mass along their bottoms.

https://algorhythym.wordpress.com/2011/09/25/the-mercator-map-of-1538/

His 1569 map shows both circular maps of half the Earth joined together circled as an oblong boundary, and the huge land mass joined as one stretching across almost the entire Earth at the bottom.

Why would his maps start with two flat halves of Earth both bound by a circle, then morphed together into an oblong boundary, while having a massive land mass stretching out over the bottom area?

Antarctica wasn’t supposedly discovered until centuries later, so why would he put a huge land mass stretching across his circular flat earth maps?

This proves they took flat Earth maps and then attempted to revise them into a ball Earth map, and revise the circular ice wall boundary of Earth into another continent for the bottom of their ball Earth. 

Why would they use flat Earth maps if they said it was a ball?

They wouldn’t, they’d have made their own maps of Earth as a ball, and if they hadn’t ‘discovered’ a massive continent on the bottom of their ball Earth yet, they’d not put anything there, or say it was not known what is there on their maps, or any patch of ice they did find there.

It’s most interesting that his maps of Earth would show a land mass that dwarfs every other continent on Earth, while it has yet to even be discovered yet, and it is the largest land mass shown ON his maps!

Also note a tiny land mass shown in the 1569 oblong map, on the left of the massive land mass nobody has discovered yet!  Yes, it would be Australia, now placed closer to where they want it, but it is far tinier than that huge phantom land mass below it!

Do you see what they’re trying to do here?  Make the Earth’s circular ice wall boundary into a continent nobody has a clue about that is the size of America, by stretching it out across a flat or oblong map. It is the only land mass shown on both halves of the Earth maps, each of them bigger than the continents above them! When they form it into a ball, the large stretched out land mass across the bottom, which looks 10 or 20 times the size of Australia, and 4 or 5 times the size of America, which is supposedly not known to even exist at that time, is the most prominent, most large, and the only land mass shown on both halves of Earth, and spans across most of the morphed oblong Earth!

These maps show the early progression of turning our real maps of the flat Earth bound by a circular ice wall, and forming it into another continent on the bottom of their Earth ball, which has no life, and is entirely covered in snow and ice, and has ice ‘shelves’ that are hundreds of feet high, but only part of it!

And why would they show a huge land mass across the bottom of Earth? Because when they transformed it into their ball Earth, it becomes much much smaller than it looks in those maps, forming into a concave land mass curving over the bottom.

That’s why this huge land mass is stretching across Earth, while they claim it wasn’t known to exist back then! So why would he put it into his maps, if it wasn’t known to exist until centuries later?

They made up the ball Earth lie, took our actual maps of the flat Earth, removed the circular ice wall, and turned it into a continent of ice with no life on it, that wasn’t to be ‘discovered’ until centuries later, somehow our explorers never noticed this massive continent just 250 miles below South America!!😂

Wrong again.
Captain Cook did it before Byrd was even alive.

Yet again you just spout whatever delusional BS you want to pretend your fantasy is true.

You are also misquoting him.

Many of the first maps of Earth  show a circular boundary around it
You mean they are limited. And they have chosen a circular shape for the edge.
Notice that that circular shape doesn't correspond to Antartica.

Note that it shows two separate halves of Earth, each of them bound by a circle.
Yes, as if you take a globe, cut it in half, and then flatten out each half.
This is nothing like your fantasy.

And again, this had nothing to do with your delusional fantasy of trying to pretend a FE was actually a globe.
It was an attempt to show a spherical Earth on a flat surface.

Why would his maps start with two flat halves of Earth both bound by a circle, then morphed together into an oblong boundary, while having a massive land mass stretching out over the bottom area?
Because if you start with a sphere, one simple thing to do is cut it in half and flatten it out.
But like all flat maps, this has problems.
For starters, it has a large section between the 2 circles which aren't connected, yet in reality are connected.
It is also quite complex with the distortions introduced, and trying to find bearings.
The Mercator projection is a much simpler distortion, only has the disconnection on the one side of the map (the north and south are a point), and while you can't easily draw the shortest path, you most certainly can easily draw the simplest.

As for the bit at the bottom, there are a few suggestions floating around.
One is that the map is primarily for navigation, and it isn't wise to go that far south.
Another is just that they believed there should be a large southern continent to "balance" the mass up north.

Either way, it is not showing Antarctica.

But consider it from your delusional BS.
You are claiming there is an elaborate conspiracy to fake Antarctica, which is so complex and elaborate, yet they fucked up so easily by including such an obvious problem?
You are basically claiming they are geniuses that can do no wrong, yet they are complete imbeciles making such careless errors.

This proves they took flat Earth maps
No, it doesn't.
In order to claim such crap you need to provide this magical Flat Earth map which is accurate and not distorted. Where is it?

You also need to explain how the globe manages to show Earth without distortion.

And this in no way refutes the fact that plenty of people have circumnavigated Antarctica in far too little time for your fantasy.

Why would they use flat Earth maps if they said it was a ball?
Because a flat map is much easier to transport and use than a globe at a comparable scale.

Do you see what they’re trying to do here?
I see what you are trying to do here.
Ignore the evidence that shows Earth is round, spout entirely baseless claims, and pretend your paranoid delusional fantasy is true.
