I suppose if you could convince whoever is granting you money that it's appropriate to assume the Earth is flat, that you'd have a good shot at getting the funding.  Especially since the nature of the core is fairly well understood, and the nature of the underside of the Earth is completely unknown to science.
I don't know what you're implying, but you're probably wrong.

I'm bored so I've decided to register and slug it out for shits and giggles with this.

Alright, let's start with a fact that anyone can see:

Readily observable astrological bodies, as seen through even rudimentary telescopes are round.  Stars, planets, and moons observed in the sky are all round, for all intents and purposes.

"Now!" you might say, "They may all just be facing the correct direction and we can't observe the fact that they are flat!"

So, my answer?

The likelihood that every observable body in space is facing in precisely the correct direction to give the illusion that they are all round is, to be brutally frank, laughable.  There are, in the readily-viewable stars with a basic telescope innumerable bodies viewed that are round.  Using more advanced equipment at somewhere like an observatory (which I have had the privilege of doing) one can see entire clusters of round objects.

"What does this all mean?" a Flat Earth believe might ask, well it means that the Earth is accepted as an astrological body in space (unless, of course, you would like to say that 'propaganda' is supporting the idea of 'space) and thus is like its brethren in that it is...round.

First, I've never been that fond of astrology, and I'm not sure what it has to do with the shape of the earth.

Second, if Apples, oranges, limes and limes are all round for intents and purposes, surely bananas can't exist.

the evidence backing it up, for lack of a better term, pretty damn good.

There is no proper evidence which backs up the RE. Neither Aristotile, Galileo, Copernicus, or Newton followed the Scientific Method before coming to their conclusions. The Scientific Method is not even attempted.

I rely on much more up to date evidence for RE than those four. Plenty of evidence from many space agencies, scientists, etc. Of course you will say that they are all in on the conspiracy and so therefore all their evidence is null and void. I can equally claim that Rowbotham et al were practical jokers and wrote their books for fun or that they had their own flat earth conspiracy determined to make people believe the earth is flat for their own purposes.

I could write why all reasons that made me believe  in the RET and also post some evidences, but since any proof that suport RET is instantaneously dismissed as false or faked, I won?t bother.

Anyway, and even if I wanted believe in the FET I couldn?t, the FET goes again all basic principles of logic and common sense.

Robosteve, judging from your posts you come across as someone believing in the FET because you don't like thinking like the rest of us. Even though you might, at the back of your head or deep down inside believe the earth is round, that would make you think like the rest of the world, and you just can't stand that.

This is how I read you, label you, nothing personal.

And for the conspiracies, what would this website, the books published on the FET be without a flat earth? This is more like the conspiracy. Every idea has it's own benefits, this is just another one of those.

If there was a flat earth, wouldn't the sun appear to be getting smaller instead of going down? Not the entire earth can see the sun at one time, and I fail to see how that is plausible.

I believe the earth is a sphere due to evidence that is hard to ignore. For example, i have travalled in a plane around the circumference of the earth and i have lived to tell the tale (as you can see, i didn't fall into a bottomless abyss or disappear over the edge of a giant waterfall into outer space). Even though i travelled from east to west, it is also possible to travel north in a straight line until one reaches exactly the same place again.

Ive also seen photos taken of the earth from space, though im sure many people would say they are a hoax, just like man landing on the moon was all a giant hoax (though, who could be bothered to create a hoax that spans several decades??).  And astronauts? I suppose they are simply part of international governments conspiracy to hide the fact that the earth is flat and simply are told to say that it is round. Or maybe astronauts are normal human beings who have been in space and seen with their own eyes that the earth is a sphere? The International Space Station? How does that manage to circle the circumference of the earth if there is no spherical earth to circle? And what about other planets? are they round too, or is the earth just special and is the only blessed with being flat?

It isn't really a matter of believing in the earth being round, I don't really have a choice, it's more a matter of accepting the obvious, coming to terms with the facts, getting over it and finding a more believable theory to talk about (i suppose the FSS Flat Sun Society will be next)

Well, Cristina, the problem with this is that they will direct you to the FAQ, or instruct you to "lurk moar," suggesting that all of these things have been covered. I've tried to explain that here: http://theflatearthsociety.org/forum/index.php?topic=29916.msg727352#msg727352

Best to just stick with the idea that you learned about the elements of a sound theory, and know that RE fits that.

Because all the evidence points to a round earth.
And no one has yet to show how this evidence is flawed. Therefore, if there is proof for a round earth, and no proof for any other shape, the earth is then most likely round.

I never said it was an excuse either way.  The point I make is that RE has at least had a stab and managed to get reasonable evidence to back up the claim.  It's only a theory.  It could well be wrong, but the odds aren't that great.

Now imagine there are two groups of scientists looking to get funding for an experiment. One of them presents their proposal as "assuming the Earth is round, we are trying to determine the nature of the core of the Earth". The other says "assuming the Earth is flat, we are trying to determine the nature of the underside of the Earth". Given the present day attitudes towards Flat Earth believers (as evidenced by nearly every RE noob on this website), who do you think will get the funding if it is a choice between those two only? Then tell me if you think it's any wonder RE has a more developed theory than FE.

thats so fucking stupid. they say that about global warming as well. when you get you funding what do you do with it? you research more into it. duh you get the funding into your area. fuckn hell

Because if the earth was truly falt and that we are going upward we would have collided with another planet by now...and also why havnt Aeroplanes been there...if the earth was truly flat someone would have been there by now...and the reason we dont fall off is because there is a little thing called GRAVITY!
here is more proof
Now that we have access to space, the easiest way to prove the Earth is spherical is to leave it and view it from a distance. Astronauts and space probes have done just that. Every picture of Earth ever taken shows only a circular shape, and the only geometric solid which looks like a circle from any direction is a sphere.

One of the oldest proofs of the Earth's shape, however, can be seen from the ground and occurs during every lunar eclipse. The geometry of a lunar eclipse has been known since ancient Greece. When a full Moon occurs in the plane of Earth's orbit, the Moon slowly moves through Earth's shadow. Every time that shadow is seen, its edge is round. Once again, the only solid that always projects a round shadow is a sphere.

This is a question that has been asked for many years, and there are some very intuitive, and some not-so-intuitive answers.

To start with... there's a horizon, meaning that the surface that one is observing from is not an infinite plane. On the clearest of days, the only restriction to one's range of sight is the horizon. There can be two explanations for this - one, that the Earth at some point just stops, as if you were looking off the edge of a table. The other is that the Earth is round. Hundreds of years ago, before the invention of the compass or sextant, precise navigation for ships was difficult, even with the stars. Ships that ventured past sight of land were often lost, and thus it was generally believed that the world simply *stopped* at the end of the horizon. With the invention of the compass, and improved map-making, people began to dare more, and with the return of Columbus from his trans-Atlantic voyage, the concept of the Earth as flat was shattered.

Further proof of the Earth being round came after the voyage of Columbus. When Newton discovered and measured the force of gravity, that number could then be tested anywhere the theory was known. Since the force of gravity is roughly the same everywhere on the globe, it could be surmised that the Earth must be spherical. If the Earth were not round, whole hemispheres would have different atmospheric pressure and significantly different sea levels. Also, pictures taken of the Earth in the last 50 years have proved absolutely conclusively that the Earth is round. These are just the arguments that don't require much physics knowledge to explain, there are others that are more technical, but I think that the simplest arguments are the best.

Answered by: Frank DiBonaventuro, B.S., Physics grad, The Citadel, Air Force officer


There are a multitude of methods in which any one can prove that the earth is a sphere. These are the most common.

You can launch a rocket to a high altitude and take pictures of the earth (which various government agencies and private groups have already done thousands of times in the past), but that isn't the most practical way. Pictures and videos taken by orbiting satellites and space stations are certainly the most definitive proof that the earth is a sphere.

But if you're not convinced, read on...

You can also observe, with binoculars, ships slowly 'sinking' below the horizon as it sails farther and farther out to the ocean, then watch them come back. They certainly didn't fall off the edge of the earth! You can also sail or fly around the world.

The Greeks discovered that the earth is round by observing lunar eclipses (i.e. when the earth blocks the sun from the moon, casting its round shadow on the moon's surface).

Another method is simultaneously measuring the length of the shadows cast by identical poles perpendicular to a flat surface that is tangential to the earth's radius at various, distant locations. If indeed the earth is round, then the shadows should all vary in length from one distant location to another, which means that the angle at which the parallel rays of sunlight struck each pole varied from one location to another. (recall the alternate-angles theorem from Geometry class) If the earth is flat, then the lengths of all the shadows should be identical when measured simultaneously, since all rays of sunlight that strike the earth are parallel. However, they are not identical, but in fact, varies in such a way that the angles indicate a spherical surface. (This was one of the earliest methods to determine the radius of the earth)

Also, keep in mind the 24 hour time zones. When it is noon in Hawaii, it is approximately midnight in the Middle East and vice versa. How can it be noon and midnight simultaneously? It is certainly impossible with a flat earth and a sun millions of times more massive.

If I were a billionaire and physically fit, then proving to you the earth is round would be no problem. I can just take you with me on the space shuttle and we'll watch with our own eyes the earth from the orbiting International Space Station.

I have heard from astronauts that there is no experience comparable as watching the earth from above.

    Today it is well known that the Earth is a sphere, or very close to one (its equator bulges out a bit because of the Earth's rotation). When Christopher Columbus proposed to reach India by sailing west from Spain, he too knew that the Earth was round. India was the source of precious spices and other rare goods, but reaching it by sailing east was difficult, because Africa blocked the way. On a round globe, however, it should also be possible to reach India by sailing west, and this Columbus proposed to do (he wasn't the first one to suggest this--see below).

    Sometimes the claim is made that those who opposed Columbus thought the Earth was flat, but that wasn't the case at all. Even in ancient times sailors knew that the Earth was round and scientists not only suspected it was a sphere, but even estimated its size.

[IMAGE:What causes horizon]
   

    If you stand on the seashore and watch a ship sailing away, it will gradually disappear from view. But the reason cannot be the distance: if a hill or tower are nearby, and you climb to the top after the ship has completely disappeared, it becomes visible again. Furthermore, if on the shore you watch carefully the way the ship disappears from view, you will notice that the hull vanishes first, while the masts and sails (or the bridge and smokestack) disappear last. It is as if the ship was dropping behind a hill, which in a way is exactly the case, the "hill" being the curve of the Earth's surface.
  To find out how the distance to the horizon is calculated, click here
Eratosthenes, Posidonius and El Mamun

    The Greek philosopher Aristotle (384-322 BC) argued in his writings that the Earth was spherical, because of the circular shadow it cast on the Moon, during a lunar eclipse. Another reason was that some stars visible from Egypt are not seen further north The full quotation can be found here.

    The Alexandria philosopher Eratosthenes went one step further and actually estimated how large the Earth was. He was told that on midsummer day (June 21) in the town of Syene in southern Egypt (today Aswan, near a huge dam on the river Nile) the noontime Sun was reflected in a deep well, meaning that it was right overhead, at zenith. Eratosthenes himself lived in Alexandria, near the river's mouth, north of Syene, about 5000 stadia north of Syene (the stadium, the size of a sports arena, was a unit of distance used by the Greeks). In Alexandria the Sun on the corresponding date did not quite reach zenith, and vertical objects still threw a short shadow. Eratosthenes established that the direction of the noon Sun differed from the zenith by an angle that was 1/50 of the circle, that is, 7. 2 degrees, and from that he estimated the circumference of the Earth to be 250,000 stadia.

      Tidbit: Eratosthenes also headed the royal library in Alexandria, the greatest and most famous library in classical antiquity. Officially it was called "temple of the muses" or "museion," from which our modern "museum" is derived.

    Other estimates of the size of the Earth followed. Some writers reported that the Greek Posidonius used the greatest height of the bright star Canopus above the horizon, as seen from Egypt and from the island of Rhodes further north (near the southwestern tip of Turkey). He obtained a similar value, a bit smaller. The Arab Khalif El Ma'mun, who ruled in Baghdad from 813 to 833, sent out two teams of surveyors to measure a north-south baseline and from it also obtained the radius of the Earth. Compared to the value known today, those estimates were pretty close to the mark.

    The idea of sailing westward to India dates back to the early Romans. According to Dr. Irene Fischer, who studied this subject, the Roman writer Strabo, not long after Erathosthenes and Posidonius, reported their results and noted:

    "if of the more recent measurements of the Earth, the one which makes the Earth smallest in circumference be introduced--I mean that of Posidonius who estimates its circumference at about 180,000 stadia, then. . . "

and he continues:

    "Posidonius suspects that the length of the inhabited world, about 70,000 stadia, is half the entire circle on which it had been taken, so that if you sail from the west in a straight course, you will reach India within 70,000 stadia. "

    Notice that Strabo--for unclear reasons--reduced the 250,000 Stadia of Eratosthenes to 180,000, and then stated that half of that distance came to just 70,000 stadia. Handling his numbers in that loose fashion, he could argue that India was not far to the west.
Columbus Again

    All these results were known to the panel of experts which King Ferdinand appointed to examine the proposal made by Columbus. They turned Columbus down, because using the original value by Eratosthenes, they calculated how far India was to the west of Spain, and concluded that the distance was far too great.

       Columbus had an estimate of his own. Some historians have proposed that he used an argument like Strabo's, but Dr. Fischer found his claim to be based on incorrect units of distance. Columbus used an erroneous estimate by Ptolemy (whom we meet again), who based it on a later definition of the stadium, and in estimating the size of the settled world he confused the Arab mile, used by El Ma'mun, with the Roman mile on which our own mile is based. All the same, his final estimate of the distance to India was close to Strabo's.

    In the end Queen Isabella overruled the experts, and the rest is history. We may never know whether Columbus knowingly fudged his values to justify an expedition to explore the unknown, or actually believed India was not too far to the west of Spain. He certainly did call the inhabitants of the lands he discovered "Indians," a mislabeling which still persists.

    But we do know that if the American continent had not existed, the experts would have been vindicated: Coumbus with his tiny ships could never have crossed an ocean as wide as the Atlantic and Pacific combined. In hindsight the exploration of the unknown may be justification enough!

    As for the size of the Earth, it was accurately measured many times since (see item "geodesy" in an encyclopaedia), one notable effort being that of the French Academy of Sciences in the late 1700s. Their aim was to devise a new unit of distance, equal to one part in 10,000,000 of the distance from the pole to the equator (as Eratosthenes showed, it is enough to measure part of that distance). Nowadays that distance is known even more accurately, but the unit introduced by the French academy is still used as the standard of all distance measurements. It is called the meter.

First of all, I asked why you think the Earth is round, not for you to copy and paste a bunch of crap from a website that advocates that position. And second of all, cite your sources.
I'm going to side with the white supremacists.

Process of elimination.

You've eliminated one possible Earthly shape. Now that we've established that you don't believe the Earth is flat, why do you believe that it is round?

If I believe the earth isn't flat, and I don't see any possible way for it to be any shape that isn't discussed, then I have to believe it's a sphere.
