Title: Proof earth isn't flat! (All you troglodytes read)
Post by: Assassin X on October 15, 2005, 12:41:14 PM
If the earth is flat then explain these points, BTW I'll be acting sarcastic with these questions:

1. Then why when the space shuttle is "Orbiting" the earth is it going in a "Circle" around a giant dirt/water/molten ball? Or is that another object?

Examples:
A: http://www.fhwa.dot.gov/wit/space4.jpg
B: http://i.a.cnn.net/cnn/2004/TECH/space/06/16/moon.mars.commission.final/story.nasa.gobeyond.jpg

2. I live on the beach of Lake Erie in Ohio (USA). Why is it I don't see Canada on the other side? Its not that far but I can't see it! I see the lights from the cities sometimes on the clouds! Is the water magically higher in the middle of the lake and it doesnt flood everything, thereby blocking the view of the city? Why?
Example (actual picutre):
http://img355.imageshack.us/img355/7084/untitled6qr1.jpg

3. When Satelittes take pictures of our planet and others why do the they go around the planets in circles? And why do the pictures end up looking like round balls???

Examples:
A: http://www.lunaroutpost.com/gallery/earth/images/earth_full_hires%20copy.jpg
B: http://www.xtec.es/recursos/astronom/mars/mars.jpg

4. If its flat then how come if you fired a rocket straight over roof tops as seen in the picture below (and pretend it had infinite fuel and it didn't lose its course) it would keep going into space?  People on the other side of eather woulnd not see it. Why?

See Here:

Theres probably more I could do but since this has to be the stupids thing I've seen since the invention of the Nuke I don't want to waste anymore of my time on it.

All I got to say is if you can deny this evidence then you are trully troglodytes. Maybe next you'll debate fires existence or maybe the wheel.

I believe this topic should be allowed in the lime-light once again, if only for question number 2:

This is a pretty big problem, especially with the Lake Michigan-Chicago thing, that thing being that only the upper portions of the skyline is visible from a park across Lake Michigan. Are there really 100-meter swells in the lake? Why would the lower, thicker parts of buildings vanish before the spire of the Willis Tower?

It would not take 100m swells to obscure part of a building that, due to perspective, would appear to be very small.

You're right. This calls for math! Let's take this picture, taken from the Indiana Dunes, 50 kilometers away from the Willis Tower:

(http://www.realhomesense.com/wp-content/uploads/2011/09/mount_baldy_michigan_city_IN_23-e1314928355906.jpg)

The Willis Tower being 530 m tall, and the lower bit of it being covered ... I'll be conservative and say the lower 150 meters are covered. The photograph is also taken about 2 meters off the ground. With the rounding from the Willis Tower, let's then say the height of our triangle is 525 m.

For this to happen, a wave's height would need to be taller the farther from the camera. It would need to follow the same ratios as 150 by 50,000. For an extremely high wave (6 m) to cover that, it would need to be closer than two kilometers. The water horizon at that altitude is ... about 6 kilometers.

Okay, fair 'nuff. I've not been to Lake Michigan (well, not on it. Wave explanation is plausible.

If my maths are correct (see below for an explanation of the equation--feel free to correct me if I'm wrong and/or provide me with the correct equations), then round-earth theory predicts the lower 200 meters of the Willis Tower would be covered. Compare the sunset photo with this diagram: (http://upload.wikimedia.org/wikipedia/commons/thumb/4/4e/Dubai-CN-Sears-towers.svg/293px-Dubai-CN-Sears-towers.svg.png)

In the sunset photo, you can clearly see where the tower's middle section ends and the top begins. There is no likewise break between the middle and bottom, implying the bottom is mostly, if not entirely, covered. The bottom section is almost exactly 200 meters tall. This coincides perfectly with that round-earth predicts.

EQUATION:

Indiana Dunes is 50 kilometers from Chicago. That is about 0.00125 the circumference of the Earth, or about .4499 degrees around the circle. The (average) radius of the Earth being 6,371.0 kilometers, we can solve a triangle with the hypotenuse going form the center of the Earth to the base of the Willis Tower and the long leg going toward, but not quite touching, the base of the camera.

With an angle between the hypotenuse and long leg of .4499 degrees, the long leg is 6,371.0 * cos(.4499) = 6370.8 kilometers. This means the base of the Willis Tower is .2 kilometers below what the camera would view as 'horizontal'.

I factored in the fact that the tower isn't going straight 'up' according to the camera, but is leaning away at .4499 degrees. However, this changed the amount covered by a few millimeters at best, so I ignored them.

You really should lurk more, but here is the short version from memory. The expected RE drop over 45.5 miles was something like 1400', and most of those buildings are shorter than that.

So because you couldn't be bothered to direct me toward the math used, you pull numbers out of nowhere and tell me to find how they were gotten myself?  That's not my issue, I'm not the one claiming the buildings would be covered entirely by the curvature of the Earth.  I didn't even claim they wouldn't, only asked for the equations which found that result. 

If you want a proof that they wouldn't, address Alex's post.  Until then, feel free to present the math at you leisure.  The actual equations, please, and not just the resultant numbers.

This quote is the result of a previous study.

The RE expected drop is 1398' at 45.8 miles. Plus 20' of the dunes. This means you could see nothing at all under 1378' if the earth is round. You can see several buildings that are 600' high. There would be no way to see the other buildings at all. The earth is flat.

Feel free to review the thread I linked earlier. Those 600' buildings would be under a lot of water, covering way past their tops. You will learn more doing your own work, rather than FE'ers spoon feeding you.

Care to cite your equations? I've cited mine and come up with a 200-meter drop over 50 kilometers (line-of-sight distance from Indiana Dunes to Willis Tower is 50.89 kilometers. Driving distance is 51.1 miles. That might be where you're getting your numbers).

I have also shown that this 200-meter drop is easily seen in the Willis Tower, since the bottom section, at about 200 meters tall, is completely hidden.

I do not know the other building of Chicago, and since most in the picture look like nondescript blocks I wouldn't be able to identify them anyway without a vast knowledge of Chicago. However, I see nine buildings, and the ninth tallest building in Chicago is the Water Place Tower at 262 meters. Now, this picture might not show the entirety of the Chicago skyline, but on face value it appears that no building shorter than 200 meters is visible.

2. Use a pair of binoculars, and you will see them. Obviously,  it is farther than you think.
3. See point 1. If you assume that satellites exist, then all sorts of nonsense can be fabricated.
4. What are you trying to say? It sounds like you are doing a thought experiment.

The Willis Tower is about 20 ft above the lake.  The photographer is about 20 ft above the lake.  This reduces the amount of line of sight blocking curvature to perhaps 37 miles.  The drop for 37 miles is maybe 850 ft.  (If someone wants to do the math for this, go for it)

Refraction would allow for a compressed view of some more that would be hidden below the water.

You should not be able to see any of this Aon Center tower.1136 - 1398 = -262. This means Aon tower should be 262' under water by RE reckoning. However you see it, and many other smaller buildings.

Here is an experiment that could easily be done to prove whether or not the earth is flat or is round.:

Maybe there are some members of the USN or persons taking a cruise from....For example : Say.... San Diego or San Francisco to Honolulu. There should be plenty of persons.

Take some pictures as you start to sail westward.

See which you observe.:

1.FE says that since the earth is flat the buildings will just get smaller as you proceed westward and if you had a powerful enough telescope you could always brings them back into vision no matter how far away you might be from them.

2.RE says that since the earth is round as you proceed westward due to the curvature of the earth the bottoms of the buildings will first disappear and eventually the tops of the buildings will disappear and there is no way you can bring them back into vision with a telescope, no matter how powerful it might be.

Maybe someone can supply the forum with some pictures to prove which is true : #1 or #2. ?

I have proved #2 to be true from personal observation. Unfortunately, I didn't think to take pictures. It's just "common knowledge" but of course FE won't accept that. They probably won't accept any photographs either. Once again this is The Flat Earth Society Forum and anything RE will post is either fake or photoshopped.

Are you going to acknowledge refraction at all, or just post a chart with the actual drop distances?  Because perceived drop is different from actual drop, and refraction is a very real occurrence that affects how far the perceived drop would be.

Edit:  As a minor point, but nowhere in New Buffalo, Michigan is there a location forty eight miles from the Willis Tower.  From the coast of New Buffalo to the Willis Tower, the distance is closer to forty five and a half miles.  From the city limits of New Buffalo on land, the distance is closer at forty seven miles.  And from the actual coast of Chicago, near to the Chicago River, the distance is slightly under forty six and a half miles.  Parts of uptown Chicago are that far, but at the very least the entire photograph isn't as distant as the headline claims.

Distances courtesy of Google Maps, fact checking, and intentionally pointing out minor flaws in your argument to avoid boredom.

What was the height of the camera ? This should be taken into account also unless the photo was taken with the camera at water level.

On the dunes, probably 20' above the water, wich can be subtracted from the total RE drop. 1398- 20 = 1378

Look at the data presented and study it. If you want to keep denying the obvious, you are certainly welcome to.

Start factoring in refraction and I will.  Again, a very real and observed phenomena regardless of the Earth's shape that can cause the viewing distance to be further than expected given the drop of the Earth.  Heck, you can probably even get the average humidity above Lake Michigan to more accurately calculate how much the refraction would affect the light.  Or you could be lazy and leave part of your point unattended to, but then it's not proof against a round Earth.

Here is all the data on the office buildings in downtown Chicago. Willis tower is 1482' high. Aon tower is 1136' high, the second highest building. You should not be able to see any of this Aon Center tower.1136 - 1398 = -262. This means Aon tower should be 262' under water by RE reckoning. However you see it, and many other smaller buildings. This could not be possible on a round earth.

I did a quick Google search of photographs of Chicago from New Buffalo and these two were the only ones I found:

(http://krfoto.zenfolio.com/img/s9/v17/p345511614-3.jpg)
(http://farm2.staticflickr.com/1009/1383483549_e4cddc52e6_z.jpg)

The problem with these is that they're impossible to tell how high off the water they are. It's certainly not at the water's edge, which makes calculating drop distances a bit more difficult. For my calculations, a camera at height h will have the same view as a camera x kilometers closer, with x being the horizon of the camera at height h.

First, let's calculate the base drop of a camera at water level of the upper picture (all references will be to that upper picture, by the way). That pier gives a good indication that the picture was taken near 41 48 03.30 N, 86 44 51.43 W. From there to the base of the Willis Tower is 74.29 kilometers. That gives us a drop of 434 meters[nb]The equation I'm using is h = Rearth - Rearth * cos[(d/Cearth)*360] with d being the distance form the camera to the object[/nb].

The road near the beach at which this photo was taken is 10 meters above the surface of the lake. Assuming the photograph was taken there, that gives it an effective view of a camera 11.3 kilometers closer to Chicago (that is, a camera floating on the lake 11.3 kilometers from New Buffalo would be able to see both Chicago and the camera at New Buffalo).

This new data gives us a drop of only 312 meters. Now, let's calculate for each of the other identifiable buildings in the picture.

Right of Willis Tower are a trio of buildings, two tall and the middle one short.
The left building is Aon Center (346 m, drop of 301 m for 45 m visible)
The right building is Trump Tower (357 m (roof), drop of 305 m for 52 m visible)

The far right is the John Hancock Center (344 m (roof), drop of 304 m for 40 m visible).

In general, the drop for the skyline of Chicago is around 306 meters, the closest buildings experiencing only 284 meters. There are seven buildings taller than 290 meters. While there are a few more visible in the picture, keep in mind the second photograph.

In that one, only the Aon Center is visible in the middle, with the Trump Tower, both physically and apparently taller, completely missing. This shows that refraction can account for at least 50 meters either way, which puts both pictures easily within the realm of RE possibility.

It seems you are making this more complicated than need be. The drop over 48.5 miles is 1398' according to RET. Look at the heights of the buildings that are seen, some are 600' high. They should be  way under water, but as you can see they are not. Subtract the building height from 1398, that tells you how far under water the building should be. Surely you can tell that those buildings are not under water.

Already factored 20' on the dunes. Makes it 1378, still taller than almost all of those buildings. I'm done here.

Put the math up, friend.  Just saying you've factored it in doesn't mean it's right, or prove that you even have.  Or that you've factored in refraction, which you seem persistent on ignoring.

The RE expected drop is 1398' at 45.8 miles. Plus 20' of the dunes. This means you could see nothing at all under 1378' if the earth is round. You can see several buildings that are 600' high. There would be no way to see the other buildings at all. The earth is flat.
The Willis Tower is about 20 ft above the lake.  The photographer is about 20 ft above the lake.  This reduces the amount of line of sight blocking curvature to perhaps 37 miles.  The drop for 37 miles is maybe 850 ft.  (If someone wants to do the math for this, go for it)

Refraction would allow for a compressed view of some more that would be hidden below the water.
The expected drop over 48.5 miles is 1398'.
If the camera and buildings were all at water level, but they aren't.

Having the camera higher effectively increases the distance before it's line of site intersects the water. 

According that chart in ENaG, There is a 20 ft drop after 5.5 miles.  With the camera at 20 feet, the curvature that actually blocks the view doesn't start for 5.5 miles.  The building is also 20 feet above the lake, giving it a 5.5 mile advantage at the other end.

Measuring from where that picture was taken from to downtown I get about 46 miles - 11= 35 miles worth of drop along the line of sight, which is about 850 feet according to ENaG.  Someone who knows the math can figure it out better.

Compared to other photos, it looks like the bottom of the buildings are compressed a little, which would be refraction making more of them visible.

Am I correct in saying you do not believe in refraction? Are you aware that your eye has a lens in it, which uses refraction to focus images onto your retina? And that binoculars, refractive telescopes, and microscopes use refraction to magnify images?

Refraction is real, and can be measured, predicted, and observed. 'Bendy light' cannot. Forgive me for not believing in an unobserved and unproven phenomena, and for accepting a known, understood, and easily reproduced one.

Hey, Ski, if you feel like disproving refraction then that's for another thread.  Until then, it's a very well documented phenomenon which should be accounted for.  It's the same thing that makes a spoon handle appear severed in a glass of water, so you don't need to be a scientist to test it.

Every turn?  That is a bit dramatic.  I see it invoked in circumstances such as this where you are taking in to account all factors that may affect a view at a distance.  Please keep your criticism accurate.

Perhaps it's because atmospheric refraction is often a perfectly reasonable explanation for otherwise unexplainable phenomena.  The problem is that atmospheric conditions are generally not documented well enough to determine whether or not refraction would be a significant factor in the observation.  However, the fact that certain refractive events will occur under certain conditions means that atmospheric refraction can not be automatically invoked or dismissed without knowing what conditions were present at the time of the observation.

 1376' is higher than all but 1 of those downtown Chicago buildings.  1136' is the height of the the second tallest building. However you can see many more of them.

Refraction is not necessary to continually calculate.  If you look at the image and it consistently shows the same appearance it is not a mirage. Because weather patterns constantly fluctuate, no mirage is ever consistent.  If I recall correctly, Rowbotham worked at the Bedford Canal for approximately nine months.  This proves that his experiments stood the test of criticism due to their frequent performance.  There existed no recorded change...  Thus, no mirage..

This knowledge holds fast onto these pictures as well.  A mirage every time fails to occur every single day.  Remember please that there are seasons and alterations of temperature and air within these seasons.  You will inevitably fail when you say," every single image possesses some form of a mirage." 

Superior mirages usually occur in arctic climates.  Truthfully, there is nothing like the arctic in these locations.  An inferior mirage or inferior refraction would be more common in these locations than a superior one.  For those who do not understand what a superior mirage entails, the image appears above the line of sight.  However, inferior mirages result in a sinking effect...

To sum it all up, do the experiment every day continuously through different season.  This eliminates the probability of the image being from refraction.

There exist certain experiments that I possess a deep knowledge as to how to perform them.  The type of experiments that even if refraction did occur, there appears the opportunity to still acquire data.  It involves measuring across two points in the distance.  When you take an island that measures approximately 22 plus miles long or two ships twelve miles separate, the horizon you receive is always level when using a straight edge to compare.  Even if refraction does occur with the two points, their relativism will remain unchanged.  The earth is flat and remember gravity does bend light as well...

How can gravity be so powerful as to bend light enough to mimic refraction but not powerful enough to bend earth into a sphere (the most gravitationally efficient shape)? Additionally I also have deep knowledge of an experiment to prove refraction. Take a straw. Put it in a glass of water. Observe.

Yes, please. But to make this image properly, please take into consideration the following image and explanation:

(http://krfoto.zenfolio.com/img/s9/v17/p345511614-3.jpg)

The orientation of that pier in relation to the Willis Tower indicates this image was taken around 41o 48' 04.98" N 86o 44' 49.45 W at an elevation of at least 11 meters[nb]The ground at that area is 11 meters above the lake, but there appears to be a walkway that might be a few meters off the ground. Still, 11 is probably a good number to use.[/nb] above the surface of Lake Michigan.

The four most easily-identifiable buildings are, left-to-right:

Willis Tower, 74,282 meters away, 6 meters above the lake
Aon Center, 73,195 meters away, 17 meters above the lake
Trump Tower, 73,659 meters away, 12 meters above the lake
John Hancock Building, 73,528 meters away, 5 meters above the lake

I could try to identify the smaller buildings for you, if you wish, but that'll take time. Here's what I think the other buildings are, from left to right:

311 South Wacker Drive, 74,261 meters away, 6 meters above the lake
Franklin Center, 74,220 meters away, 6 meters above the lake
Legacy Tower, 73,489 meters away, 6 meters above the lake
Aqua, 73,099 meters away, 6 meters above the lake
Olympia Center, 73,504 meters away, 5 meters above the lake
Water Tower Place, 73,443 meters away, 5 meters above the lake
900 North Michigan, 73,676 meters away, 4 meters above the lake (this building is the rightmost two blocks)

The RE expected drop is 1398' at 45.8 miles. Plus 20' of the dunes. This means you could see nothing at all under 1378' if the earth is round. You can see several buildings that are 600' high. There would be no way to see the other buildings at all. The earth is flat.
The Willis Tower is about 20 ft above the lake.  The photographer is about 20 ft above the lake.  This reduces the amount of line of sight blocking curvature to perhaps 37 miles.  The drop for 37 miles is maybe 850 ft.  (If someone wants to do the math for this, go for it)

Refraction would allow for a compressed view of some more that would be hidden below the water.
The linked chart below is an accepted view on RE drop, it uses the pythagorean theorem. I have personally verified it's accuracy, you are welcome to also.

The expected drop over 48.5 miles is 1398'.

 Here is all the data on the office buildings in downtown Chicago. Willis tower is 1482' high. Aon tower is 1136' high, the second highest building. You should not be able to see any of this Aon Center tower.1136 - 1398 = -262. This means Aon tower should be 262' under water by RE reckoning. However you see it, and many other smaller buildings. This could not be possible on a round earth.

Click on the other building to obtain their height and other data.

I hope this helps.

Hoppy. It was a nice thread you brought up, but you fail to miss one point. I can see where lolflatdisc made a mistake in his calculations and you perhaps see that as a victory for the flat earth theory... but still....just have a look at the photo!! The fact that the bottom parts of the buildings are missing, means these are hidden behind the horizon, which could only corresponds with a spherical earth. Tall buildings, several hundred feet tall and you only see the very top. It is proof a spherical earth and you do not need to understand any calculations. Simple but important point, proofing the earth being a sphere.

DQ only the top of the Willis Tower could poke above a RE horizon. Clearly you can see many more buildings which should be hidden if the earth were round.

There is still the problem of the bottom portion of the buildings being obscured by the horizon. At 20' elevation for both the photographer and the buildings' bases, it's not very likely that waves are getting in the way, they'd have to be 20' high just to obscure the ground beneath the buildings! To have a significant portion of the buildings themselves actually obscured, there needs to be another explanation, and FET just doesn't have one.

Refraction would allow for a compressed view of some more that would be hidden below the water.
The expected drop over 48.5 miles is 1398'.
If the camera and buildings were all at water level, but they aren't.

Having the camera higher effectively increases the distance before it's line of site intersects the water. 

According that chart in ENaG, There is a 20 ft drop after 5.5 miles.  With the camera at 20 feet, the curvature that actually blocks the view doesn't start for 5.5 miles.  The building is also 20 feet above the lake, giving it a 5.5 mile advantage at the other end.

Measuring from where that picture was taken from to downtown I get about 46 miles - 11= 35 miles worth of drop along the line of sight, which is about 850 feet according to ENaG.  Someone who knows the math can figure it out better.

Compared to other photos, it looks like the bottom of the buildings are compressed a little, which would be refraction making more of them visible.
The math doesn't work that way. Take the total distance, find the drop over the total distance. Then subtract 20' for being on the dunes, subtract a couple of feet, because downtown Chicago is a couple of feet above sea level. 1398' - 20' - 2' = 1376', which is the drop on a round earth
 1376' is higher than all but 1 of those downtown Chicago buildings.  1136' is the height of the the second tallest building. However you can see many more of them.

Keep repeating that and it might one day be true. If you're talking about RE drop, then you have to use RE maths which is a bit more complicated than the simple trigonometry involved in FE maths. Take a look at this diagram:

(http://i.imgur.com/2NLcl8L.png)

The orange line is the line-of-sight of something directly on the water of Lake Michigan (distances and curvatures greatly exaggerated, by the way). As you can see, it completely fails to see the target building (the long line)

A distance above the lake, it is able to see the building because it can now look down to see the horizon. The blue/purple line intersects the building a lot farther down than h1 units lower than the orange line.

But notice how the blue-purple line is tangent to the Earth? If we placed a camera where it touches, then it would have the same view as the original (thus, the purple line). That's why it's easiest to calculate 'drop' from a camera on the surface of the lake at the horizon of the original camera than it is to calculate the drop from the original camera itself.

As explained earlier, it is easiest and most correct to find the total horizontal distance. Calculate the RE drop, then subtract the camera height and the building heights. Our vision and camera resolution make it nearly impossible to make out details from nearly 50 miles. However we can clearly see the buildings are not behind the horizon, rather sitting on it.

You're calculating the horizontal drop of the orange line and then subtracting the height of the viewer. Look at the diagram and you can see this is clearly not correct. Until you understand this extremely simple idea, you're just talking out your arse. Your way may be easier, but it's certainly not correct.

Hoppy, the fact the bottom parts are missing of buildings which are hundred of feet high is only possible on a spherical earth, since they are below the horizon due to the curvature of the earth. It is the easiest to see and understand observation. You do not have to do any math. The missing bottom part suffice the earth is a sphere. Don't be stubborn about it, it is the way it is.

I will make a .dwg file tonight and we can settle this while letting anyone who cares also look at the raw data.  I will also post a screen shot, so you people do not have to worry about format.

How's that coming?  I'm curious to see it.

I did a 200x30,000 pixel diagram using the figures from ENaG to create the curve.  Not sure how well it would show up here though.

Here's my rather simple not-to-scale diagram in addition to the one Alex posted.

Green = line of sight from '0' elevation
Red = elevated
Blue = line of sight to base of building showing height of curvature 'hill'
L Green = length of 'hill' and drop actually blocking line of sight
purple = rough estimate of refraction

(http://img89.imageshack.us/img89/1899/ibui.gif)

I based this off the diagram and drop tables from ENaG.

3 miles = 72in drop, so if I raise my point of view 72inches, I can now see to a point 3 miles distant, plus exposing far more than 72 inches of something further beyond that.

Not that hoppy'll respond, but I can try...:

Hey Hoppy, notice how the difference in the light green and dark green 'drop distances' is a LOT more than the altitude of the camera. Yeah. That's why you can't just subtract 20' from the drop distance and call it good.
Title: Re: Proof earth isn't flat! (All you troglodytes read)
Post by: hoppy on August 06, 2013, 06:27:38 AM
@29, what's with the point of the 3 miles? The total distance is almost 50 miles. Get the total RE drop, then subtract the elavations, ie the height of the camera, the height of the buildings.
Title: Re: Proof earth isn't flat! (All you troglodytes read)
Post by: 29silhouette on August 06, 2013, 08:19:01 PM
Actually the total distance is about 46.5 miles (from where the photographer put a marker for the picture location to the Willis Tower).

I put the diagram from ENaG in there showing how it coincides with my diagram.  From an elevation of 'zero' the drop would hide a lot below 72inches after 3 miles.

By raising up 72 inches, one could see the surface at 3 miles before the drop starts to hide anything.  Even then, looking at where the 4 and 5 mile marks would be, a lot more than 72 inches of something would be visible at those distances.

Maybe jroa's diagram will show something different.

According to the "supported"* world map, reposting for convenience,

(http://www.theflatearthsociety.org/wiki/images/4/43/Map.png)

it would imply there is a significant difference in the distance between, say New York and Lisbon, versus Rio Gallegos and Cape Town.

Basically I just said mid North America to western Europe versus southern South America to southern Africa, for ease of reference.

Rio Gallegos to Cape Town: 6,970 kilometers.

New York to Lisbon: 5,422 kilometers.

Now, compare those distances to the FE world map. It does not seem to add up. Care to explain?

Blue = higher elevation line of sight

These lines are straight and don't take refraction into account.

For my thousandth post I present the following model of the Chicago skyline from across Lake Michigan. For a refresher, this is the photo I modeled:
(http://krfoto.zenfolio.com/img/s9/v17/p345511614-3.jpg)
That is Chicago, viewed from New Buffalo, around 73 kilometers from the Chicago city center. The positioning of that pier indicates the photo was taken from somewhere around 41.80138° N 86.74707° W from an unknown height of around 11 meters above the surface of the lake.

Note: While completely to-scale, the diagram does make a few approximations. For instance, it assumes the Earth is 6371 km in radius at the plane of the diagram and 40009 km in circumference.

Here's also a key to the diagram:

Please click on the images for a full view. Alternatively, right-click and select 'View picture in new tab'.

(http://i.imgur.com/oNKwSL9.jpg)

(http://i.imgur.com/ddjkBEI.png)



Building Identities
The four tallest buildings in the photo are very easy to identify, and thus have earned the solid line in the diagrams. The smaller buildings are much more difficult, and I really have no clue as to their actual identities. It should be noted that the third building from the left (Franklin Center) appears shorter than the first from the left (311 South Wacker Drive) even though the diagram positions it the other way around. This means that either I have the identities very wrong or there exists some optical effect that distorts the true building sizes.

Note that the dotted green line also acts as a 'horizontal' for Observer O at 11 meters above the lake. Anything below that line means the buildings are actually beneath the photographer.

I have a query about this picture.
Ok, as we can see, half the buildings disappear and this is attributed to the curvature of the earth, right?
Well here's my problem with this.
If that is the case, we also are told that the earth is round, so it should curve from right to left but that line looks perfectly straight, yet my real query is.
If the buildings disappear by half, over that distance, then they should also  angle away from each other, for instance, they should be slightly leaning left and right from that distance, also.

They may be spirit level straight up when your a mile away or a bit more, but not from that distance. Any reason why they are bolt upright, if the earth is a globe?

This is because the buildings are so close together. If they were very,very,very far away from each other than you would be able to see them lean away from each other.

I disagree with you phoenix. Its just too far away too notice and the difference in curvature isn't enough to notice such an effect.

The reason why the horizon doesn't appear to curve is because well... that really doesn't make any sense. No matter where you look at that horizon you are equidistant away from it. If what scepti was proposing were to occur then the horizon behind you would have to be much lower. You can imagine an ant on a basketball and notice that from the ants view, the horizon is always equidistant from the ant. Alex created a nice model in a geometry program that shows the altitudes which you should be able to see the curvature. You can find it the debates section.

I'm not buying that for one second. You can't harp on about the curved earth and disappearance and then come up with, "oh they are too close together" to lean, left and right, when you should see an offset from that distance.

Cool! Thanks for that. :D But either way you would not see the buildings leaning away from each other.

I have a query about this picture.
Ok, as we can see, half the buildings disappear and this is attributed to the curvature of the earth, right?
Well here's my problem with this.
If that is the case, we also are told that the earth is round, so it should curve from right to left but that line looks perfectly straight, yet my real query is.
If the buildings disappear by half, over that distance, then they should also  angle away from each other, for instance, they should be slightly leaning left and right from that distance, also.

They may be spirit level straight up when your a mile away or a bit more, but not from that distance. Any reason why they are bolt upright, if the earth is a globe?
You're right, they should. But how much? Assuming each building is built perfectly perpendicular to the Earth's surface, than each should appear to another to be listing away just a little bit.

Let's calculate this list between the Willis Tower (second from left) and the camera. The distance is 74.3 km, or 0.0018557 times the circumference of the Earth. Multiply by 360° and we get a list of .668°. Since that list is directly away from the camera (it's leaning backwards) really the only indication this would be happening is it would appear shorter--3.6 cm shorter to be exact. Hardly noticeable at 74.3 km.

Now, the Willis Tower and the John Hancock Center (that's the tallest building on the right, number 10 from the left). also list away from each-other, which, as you say, would be seen from the camera's perspective as them, well, leaning away from each-other. They are 2.4 kilometers apart, or .00005996 times the circumference of the Earth. Multiply by 360° for a total angular difference of 0.0216° or 1.3'. That means that the difference in the tops of a JHC parallel to the Willis Tower and the current JHC would be about 17 centimeters.

Once again, not noticeable at the 73.5 distance between the camera and the JHC.

So you're right that they should be tilted away from each-other and from the camera, but the tilt isn't visible on such a small scale. On a flat earth the Willis Tower would appear less than 4 cm taller, and the JHC would appear 17 cm closer to the Willis Tower. At this distance, such tiny variations are invisible.



Edit: For reference as to what a JHC 17 cm closer to the Willis Tower would look like, the width of the JHC visible from this photo is about 32 meters, making each pixel about 10 meters wide. The tilt away would be about 1/10th the width of a pixel. In other words, undetectable.

Incorrect goat boy. If it was flat,the entire building would be visible. If its a sphere then any part of the building could be missing and however much that is just depends on the amount of curvature which is derived by the size of the sphere. It's basic geometry.

The biggest problem for me is (and always has been with these photos) that on a flat earth, the entire skyline should be clearly visible, not just this handful of buildings, which are clearly partially obscured, despite the viewer's elevated position (which would allow him/her to see more of the building than you might think, as has been explained).

Things disappear into the distance. You watch a plane fly by, a couple of minutes later you can't see it. You saw stay up in the air, it just disappears because our vision is not good enough to see something the size of a plane at that distance. Those buildings that you can plainly see are supposed to be under hundreds of feet of water.

I have no idea why you think they should be under water.

Besides, if you insist on stuff disappearing then it makes no sense that the top of the building is still there.

Because RET states that they are under water.

It makes no sense to see any part of those buildings, if you think the earth is a sphere.It is similar to ships disappearing in the distance, the bottom disappears first and you can still see the top.

Exactly. That proves it is round. It says a lot that you can't understand.

Do this for me please. Grab a basketball. Now grab something relatively short like half a tooth pick. Put your up close to the ball and tooth pick. Now, while keeping the tooth pick on the ball like a building to the earth rotate the ball away from but keep your eye right on the surface. You'll notice the tooth leaving your view starting from the bottom.

You do know that that is because of distance right?  The curve makes the bottoms disappear before the tops. As you get further away the ground drops more and more and you see less of the buildings (from the bottom up) until you can't see the buildings at all.

Actually, Hoppy, I recently did a post that conclusively shows that at least five buildings should be clearly visible above the water (http://www.theflatearthsociety.org/forum/index.php/topic,674.msg1539175.html#msg1539175). If you have problems with the model please bring them up. The math has been explained about 4 pages back, so you can look there, too, for ideas on where I've obviously messed up.

If buildings disappeared because they were too small to see, why are the thinner tops visible when the thick bottoms have vanished?

Building Identities
 It should be noted that the third building from the left (Franklin Center) appears shorter than the first from the left (311 South Wacker Drive) even though the diagram positions it the other way around. This means that either I have the identities very wrong or there exists some optical effect that distorts the true building sizes.

Very nice. 

About that building appearing a different size, is it possible it's a different building?  I'm not sure what year that picture was taken, but the other picture of Chicago from New Buffalo was taken in quite a while ago, and I noticed some newer buildings when I was doing some identification of my own.

Also, was the building elevation above the lake factored into those diagrams?  They average about 20 feet I think.  Or probably not enough to matter?

Now if jroa could post his diagram.

Yes they very well could be different buildings. The smaller buildings are completely guesswork for me. And yes the elevation of the buildings was taken into account. Most were 6 meters, but one was 12 I think. The full stats are on page 3, I think.

I have a query about this picture.
Ok, as we can see, half the buildings disappear and this is attributed to the curvature of the earth, right?
Well here's my problem with this.
If that is the case, we also are told that the earth is round, so it should curve from right to left but that line looks perfectly straight, yet my real query is.
If the buildings disappear by half, over that distance, then they should also  angle away from each other, for instance, they should be slightly leaning left and right from that distance, also.

They may be spirit level straight up when your a mile away or a bit more, but not from that distance. Any reason why they are bolt upright, if the earth is a globe?

The buildings are leaning but not to the left or right. They are leaning away from you. But of course we cannot see that from a 2-dimensional picture.

(http://i44.tinypic.com/wtuf4z.png)

And also, a lens does not have the same angle of view as your eyes. While your eyes can see horizontally with an angle of view of 180°, a zoom lens can only see a smaller portion of that. The more powerful its zoom factor, the smaller its angle of view will be. Assuming that you reach an altitude high enough to see the below curvature, your lens still cannot see the same curvature. You need to go much higher for your lens to be able to see what your eyes can see at a lower altitude.

So I guess it's agreed then.  Judging from the diagrams posted (no one has yet to provide a diagram showing otherwise), a slightly elevated vantage point can expose far more of an object at a far enough distance.
