Title: Strong Evidence for Round Earth
Post by: kc_kennylau on December 05, 2014, 03:13:43 PM
If the earth were indeed flat, with the north pole in the center, and the south "pole" being a circle on the outside of this disk, then would Antartica not be bigger than any continent and circumnavigating Antartica be almost impossible? Don't go claim that all videos of people walking Antartica are fake. Go there and walk yourself.

Ok, let's suppose then the south pole and the north pole is opposite of each other, meaning that the south pole is on the other side of this disk. Then why can you not drill a hole directly from the north pole and the south pole? And what about the sun? Would there be two suns to make the northern "hemisphere" the same heat as the southern "hemisphere"? And if it were like that, what about gravity? As you guys claimed that the earth is accelerating upwards by 9.8 m/s/s, so the water on the southern "hemisphere" should just fall off. So only one side of this flat earth can be used. Then what does the other side contain? And what would you see if you continue to walk south when you arrive Antartica?

Who walked around Antarctica?  You are very confusing.

Also, you claim that you should be able to drill from the North Pole to the South Pole, when no Flat Earthers have claimed that the South Pole is below the North pole.  With your logic, why has nobody drilled this hole on a round Earth?

And, you seem to be confused, and you are thinking that the sun goes under the flat Earth.  Maybe you could read our FAQ or even the wiki? 

And, finally, why would the water fall off?  Could you please explain?

Let's ignore my second paragraph. So are you guys saying that the South Pole isn't a pole?

Yes, you could. The South Pole is technically beneath the North Pole in the Flat Earth model. The magnetic field lines rise and spread out at the North pole and don't intersect with the earth until beyond the Ice Wall (and some parts in the ocean).

The needle of a compass always aligns with the magnetic field lines in its area.

And what about the sun? Would there be two suns to make the northern "hemisphere" the same heat as the southern "hemisphere"?

The earth is laid out similar to the United Nations logo. The sun is circling clockwise over the earth. The sun's path also changes radius throughout the year to create the seasons. At Summer Solstice the Sun is traveling near the Tropic of Cancer to give the Northern Hemiplane its long days and hot summers and the Southern Hemiplane it's short days and cold winters. At Winter Solstice the sun is traveling near the Tropic of Capricorn to give the Nothern Hemiplane its short days and cold winters and the Southern Hemiplane its long days and hot summers.

Quote
And if it were like that, what about gravity? As you guys claimed that the earth is accelerating upwards by 9.8 m/s/s, so the water on the southern "hemisphere" should just fall off.

The water is contained by the Ice Wall at the coast of Antarctica, like a bowl.

Quote
Then what does the other side contain?

The matter is highly debated. Some believe it to be just rocks. Others question the concept of an "other side".

Quote
And what would you see if you continue to walk south when you arrive Antartica?

This is unknown. Some believe the earth is finite and one would eventually encounter an edge. Others believe the earth is infinite and that we live on an eternal plane which bisects the universe as a fundamental part of its geometry.

If you look at the actual travel routes of trans-Antarctican expeditions, it's easy to see that they work just as well on the disc model.  They generally look something like this one:

If Antarctica is a ring continent, there is no route that transverses the continent that would be remotely plausible.  It would be a trip measuring tens of thousands of kms.

Post by: Tintagel on December 11, 2014, 04:49:37 PM
Certainly I could, but it likely wouldn't satisfy you as it would appear to be a longer route than the 3473 km figure you cite.  There is zero evidence that this is the actual route taken, and I suspect it was much more like the shorter route I posted.

I can follow this, and I'm not even a supporter of the ring continent model.  It's not that difficult.

My explanation applies to either model.

Actually, the compass doesn't work in the entire Antarctic circle... or the Arctic circle for that matter. The magnetic field lines become more and more vertical at those latitudes. Eventually you need a special swivel compass, but even that takes you so far. At the latitude of Seattle, Washington, a normal compass is already scraping against the floor of its enclosure. It is actually only a narrow strip of land where the magnetic compass works, where the majority of the population lives.

See: http://www.madsci.org/posts/archives/aug98/899130154.Es.r.html

Travel to Antarctica would have been done by another method, such as by the stars. But more than likely they are following the markers of early famous explorers from the early 1900's who claimed to have found the geographic south pole, whose structures still stand.

That link says that there are compasses that work that far north and south.  You think people traveling, even to a peninsula of antartica were not equipped properly?

There are swivel compasses that will take you a little further, where the needle is on a little bendable axle, but at a certain point the magnetic field lines point nearly straight down (http://upload.wikimedia.org/wikipedia/commons/d/d5/Geodynamo_Between_Reversals.gif). There is no compass needle that can defy 'gravity'.

If you landed on the Antarctic coast and followed signs that said "South Pole This Way," I doubt you would feel the need to double and triple reference your path against a plethora of navigating instruments. And if you did, and found some kind of discrepancy, you would likely brush it off as an interesting curiosity.

But the explorers you are referencing do not have the benefit of being you. They had no question in their mind that the earth was a globe. That's what they were taught. They followed the signs, they followed the path others before them have taken from one coastal antarctic port to the other. Compasses don't work there. Without a question that the earth is a globe and that they are truly circumnavigating Antarctica, and not a peninsula, they would have no need to be "extremely careful" to make sure that they had circumnavigated Antarctica to prove it was a continent.

Have you ever met someone who calls themselves an "explorer"? They are universally brainless thrill seekers with too much money on their hands. Scientists are not explorers. Scientists are poor, and need to work for a living. The only reason a scientist goes to explore a far off exotic location like Antarctica is if a government is funding it, and the governments of the world lost interest in exploring Antarctica pretty much after they sent the first explorers in the late 1800's/early 1900's. Today some government institutions merely send people down there to study wildlife in a single spot, then return. Thorough, investigative and fundamental inquiry of the Antarctic continent is not conducted.

Every single time someone goes down to Antarctica in a challenge to cross it they merely trace steps of the early explorers, overly prepared with warm luxuries and survival safeguards of a millionaire on vacation, with books and stories in their bags about Antarctica and the people who died there. These people are merely doing it to say that they crossed Antarctica.

I don't see anyone crossing Antarctica horizontally to those few vertical paths. A true explorer wouldn't pride himself on taking a path others have taken.

Where do compasses not work?  Today we have GPS to know our location.

Compasses do not work where the magnetic field lines are vertical, which is a good chunk of the entire Antarctic circle.

GPS works by telling the receiver how far it is from the broadcasting device. The receiver knows that, under theory, every 69.5 is one degree. So, if a receiver is 347.5 miles from the receiver, the display takes the coordinates of the broadcasting device given to it in the stream and adds 347.5 miles to it to output a degree coordinate for the receiver's location. It is possible to use this method of navigation to avoid getting lost and assign coordinate values to all of the locations near that broadcasting device.

The same devices could be used on a plane perfectly well. The xy coordinates would simply be artificial constructs used to assign location names to the surface to navigate. In order to take those xy degree coordinates, which are designed assuming 360 degrees on a globe, and use it to say that the earth is a globe, which it is not, further investigation would be required beyond the simple act of navigating from point A to point B.

The distance is determined via timestamps. A broadcasting beacon announces its time and the receiving beacon receives it and compares its own time with the broadcasting time, using the speed of light to get a distance to the broadcasting beacon.

The clock of a gps device sets itself by looking at time stamps of incoming signals from multiple gps signals and gauging its own inaccuracy.

In use, a single beacon will be able to tell you how far you are from it just fine. The other beacons are mainly required to get direction information. The receiver doesn't know precisely what direction the signal came from and needs others to triangulate. It uses the other signals to figure out the direction the first signal came from and places itself on a coordinate map.

I've read all about GPS specs. GPS receivers have clocks that set themselves, the distance from the beacon is determined via time stamp differences, the receiver's coordinates are determined via addition based on the beacon's preprogrammed coordinates, multiple beacons required to get direction information, etc.

It takes the timestamps from multiple gps signals around it and gauges its own inaccuracy. While less effective, this is a work-around solution to installing expansive atomic clocks in each gps receiver.

I am sorry you are having trouble Tom, let me try and help you. You said that these explorers were just retracing steps; this may or may not be true. If you want someone to believe you, you should quote a source that supports your position. You should not make Ad Hominem attacks against all explorers (what's up with that? Jealous?). When prompted to support your position, you should not just repeat the point again.

You evaded the question.  What if?  For what it's worth, I do think there are satellites above the earth, as I've observed them.  I don't think they are at the altitudes reported, however.

So why don't you measure their altitudes and stop just "thinking" about it? See: http://io9.com/5688939/how-to-measure-the-distance-from-the-earth-to-the-moon (http://io9.com/5688939/how-to-measure-the-distance-from-the-earth-to-the-moon)
