Experimental Evidence

The following sections contain experimental evidence in favor of a Flat Earth.

The Bedford Canal Experiments
The classic Flat Earth water convexity experiments were described in the book Earth Not a Globe by Samuel Birley Rowbotham. Rowbotham lives near the canal and performs the experiment numerous times over a long period of time. The Bedford Canal is a man-made canal which was selected as the most ideal location for the types of experiments performed due to the narrow passageways and low disturbance of the water's surface.

Of special interest, and in regards to the popularized subject of refraction, we look at the second experiment in the text.

Experiment Two
From Experiment Two of Earth Not a Globe we read:

On analysis of this experiment, if the earth were a globe, one important remark would be that it is quite the coincidence that the flags all experienced the Flat Earth refraction effect, one by one, all the way down to the end, which projected each flag into the air at the exact height they needed to be at in order to make things look flat in accordance with the distance looked across and the height of the observer.

There are multiple control points in this experiment and others. Each point is a test in the experiment. Incredible refraction coincidences would need to occur to account for them. The top of the first flag would have to have been projected 8 inches into the air, the second flag 2.67 feet, the third flag 6 feet, the fourth flag 10.6 feet, the fifth flag 14.29 feet, and the sixth flag 24.01 feet into the air, when the later flags should be below the horizon. Rowbotham is well aware of the "it was refraction" argument, and his experiment is designed to test the refraction of light rays on the flags of constant height against the taller flag at the end. The observation is artificially manipulated—controlled—to separate one explanation from another, in the effort to more truthfully determine a cause of an observation.

Weather and Wave Conditions
In the chapter On the Dimensions of Ocean Waves, Rowbotham explains that the above is affected by wind and water conditions. The reproduction works best in fine weather:



The Bishop Experiment


California Monterey Bay is a relatively long bay that sits next to the Pacific Ocean. The distance between the extremes of the Monterey Bay, Lovers Point in Pacific Grove and Lighthouse State Beach in Santa Cruz, is just over 23 statute miles.

0.06674 miles = 5,280 ft/mi * 0.6674 mi = 352.3872 feet

Hence after 23 miles the earth drops approximately 352 feet.

On a very clear and chilly day it is possible to see Lighthouse Beach from Lovers Point and vice versa. With a good telescope, laying down on the stomach at the edge of the shore near Lovers Point 20 inches above the sea level it is possible to see people at the waters edge on the adjacent beach 23 miles away near the lighthouse. The entire beach is visible down to the water splashing upon the shore. Upon looking into the telescope I can see children running in and out of the water, splashing and playing. I can see people sun bathing at the shore and teenagers merrily throwing Frisbees to one another. I can see runners jogging along the water's edge with their dogs. From my vantage point the entire beach is visible.

IF the earth is a globe, and is 24,900 English statute miles in circumference, the surface of all standing water must have a certain degree of convexity--every part must be an arc of a circle. From the summit of any such arc there will exist a curvature or declination of 8 inches over the first statute mile. Over two miles the fall will be 32 inches; by the end of the third mile, 72 inches, or 6 feet, as shown in this chart.

Correcting for the height of the observer of about 20 inches, when looking at the opposite beach over 23 miles away there should be a bulge of water obscuring objects up to 300 feet above the far beach. There isn't. Even accounting for refraction, the amount hidden should be around 260 feet - seeing down to the shoreline should be impossible.

Suppose that the earth is a sphere with a radius of 3,963 miles. If you are at a point P on the earth's surface and move tangent to the surface a distance of 1 mile then you can form a right angled triangle as in the diagram (right).

Looking over a distance of 1 mile, we can use the theorem of Pythagoras (a2 + b2 = c2):

3,9632 + 12 = 15,705,370

and when we square root that final figure we get a = 3,963.000126 miles

Thus your position is 3,963.000126 - 3,963 = 0.000126 miles above the surface of the earth.

Converting to inches, 0.000126 miles = 12 in * 5,280 ft * 0.000126 mi = 7.98 inches

Hence after one mile the earth drops approximately 8 inches.

Ergo, looking across 23 miles the Pythagorean theorem becomes:

39632 + 232 = 15,705,898

and when we square root that figure we get a = 3,963.06674 miles

Thus the drop along c is 3,963.06674 - 3,963 (radius) = 0.06674 miles (352.3872 feet)

There are a number of different methods to calculate the drop of the Round Earth. Go ahead and look a few up to try out. You will find that the drop while looking over 23 miles is on the order of 300-400 feet.

Why I'm a Flat Earther... 37 Must-See Experiments
The Flat Earth movement performs continuous validation and checks of Earth Not a Globe by Samuel Birley Rowbotham. The following is a good collection of experiments which demonstrate a Flat Earth (Runtime: 2 Hours).

Sinking Ship Effect
The Sinking Ship Effect is often used as evidence of the earth's rotundity. It was one of the first proofs of Aristotle and other philosophers. It was based primarily upon this phenomenon that the earth was declared by the ancients to be globular. It has been found that when the phenomenon is studied with modern methods, such as through long period time-lapse photography, that the Sinking Ship Effect is not consistent. The effect appears to come and go over time. See: Sinking Ship Effect Caused By Refraction

 * Flat Earth v. Sinking Comparison Ben, Taboo Conspiracy, reports that sometimes he is able to see further than the curvature of the earth should allow, and at other times things appear sunken. He compares the two scenes. In his comparison the sunken scene was more distorted than the flat earth scene. Does refraction make things blurrier or clearer?
