For FE people

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)

Its comical to me that the earth's circumference is determined by the following.

A man measures a shadow.
He then walks five miles to the next shadow and measures it.
The difference in shadows (due to his 5 mile walk) demonstrates the curve of the earth.

Ok, that was fun. But for real:
This experiment assumes a sun that is much more distant than the sun in a flat earth model. So it doesn't really apply.

Even if this fails to change your cult-like mind, look at some other facts. You will most likely also shrug these facts off as well and say something comedic.


- Countless people have seen rockets take off...
(more than 15 miles)

- We have google earth( would be impossible to constantly update info, correctly as it does, as fast as it does.

- live footage of space and earth

- The testimony of hundreds of astronauts along with countless pictures

I've seen the Shuttle take off and disappear into the sky. That doesn't mean it reached orbit, however.

- Google does not own Satellites.

- Google uses aircraft pictures and stitches them together. The Earth looks round when zoomed out because that's how Google programmed the 3D model the pictures lay on to look. The 3D model could just as easily be cube or disk shaped.

High altitude observations don't really provide proof for a Round Earth.

The reason why the earth might look round from very high altitudes is because of Snell's Law. I'm sure you have seen that when you put a pencil halfway in a glass of water, it appears to be broken. This is because water is more denser than air and light rays bend when the density and temperature of the medium changes. This is known as the Snell Law.

Have you ever seen the outside temperature readings on an airplanes' info channel? It goes all the way down to a few degrees, because atmosphere gets colder as you ascend. When one is looking down from a plane to the surface of the earth they are looking through an atmosphere that gets warmer (and therefore more dense) as it descends. This causes light rays from the earth to bend and makes the surface look curved - just like the pencil in the water getting broken. It's not a sharp break as in the pencil example but a smooth curve, because the temperature and density changes gradually, not suddenly.

"more denser" I simply love your grasp of the english language Tom.

You infer that because water refracts light and makes pencils look broken, thin air must make the earth look round.  Geez.

If google used aircraft, thousands upon thousands of airplanes would be required to scan over the earth every hour like they do, and i do not see 100s of airplanes going over my house area everyday.

People have spotted, taken pictures and located satelites in orbit.

The pictures are only updated once every three years. Google purchases its aircraft pictures from the U.S. Geological Survey (USGS) and other surveyors.

Tom you seem to have you 'facts' wrong.

Google earth Plus is continually scanning (with satelites... That are IN space)
Do you have any PhD's in physics, astronomy, geology, or anything along those lines.

Nope. You are completely wrong. That's why the expansion to my home is still under construction on Google Earth even though it has been completed for two and a half years now.

Google wouldn't be in the conspiracy, as it even goes against the government from time to time. Do your homework and start stating real facts Tom Bitchop.
GPS does not require satellites, fortunately it uses it.

Google doesn't need to be on the conspiracy. They just stitch the aircraft pictures together and project them onto a three dimensional sphere.

Tom, air density gets Lower as altitude increases. At low altutudes, the Air is being compressed by the weight of the air above it, allowing it to be denser despite being warmer.

That's exactly what I said. Maybe you should read the sentence again.

So it is. You just stated the wrong reason for the rise in density.

Are you saying that there is no correlation between air density and heat?

How hot do you think the vacuum space is one meter from the surface of the sun?

PV = nRT - The Ideal Gas Law

Temperature of a gas is inversely proportional to the quantity of said gas. (And thus density -> (Quantity * Molar Mass)/Volume )

The statement of yours which I bolded suggested That the higher temperature at low altitude caused higher density, rather than the pressure applied by the air above it.

If it is indeed a vacuum, Measuring temperature may be rendered difficult by that pesky lack of substance. If you meant the plasma in the solar atmosphere, Astronomers place its temperature in the range of a few million Kelvin. (And a particle density of less than one billionth of Earth's Atmosphere) Seems to support that whole inverse relation between heat and density.
