13) In a 19th century French experiment by M. M. Biot and Arago a powerful lamp with good reflectors was placed on the summit of Desierto las Palmas in Spain and able to be seen all the way from Camprey on the Island of Iviza. Since the elevation of the two points were identical and the distance between covered nearly 100 miles, if Earth were a ball 25,000 miles in circumference, the light should have been more than 6600 feet, a mile and a quarter, below the line of sight!

With increasing distance from the object, the earth’s curvature causes the surface of the water to fall away from the beam of light. Over one mile, the amount of drop is eight inches, but the drop increases quadratically with distance. Consequently, after three miles the drop is six feet, and after six miles the drop is 24 feet. This is the point of the Bedford level experiment—the curvature of the earth ought to intervene to prevent the mast of the boat being visible from much more than three miles, let alone six miles. However, for the light from the distant object not to be visible, it would have to travel in a straight line. But with a temperature inversion, straight-line motion would carry the light from a cooler layer of air into a warmer layer of air at nearly a grazing angle. The light cannot do this, so it continually is internally reflected, causing the light to bend around the edge of the earth. Therefore, with a temperature inversion, one can see objects that lie well beyond the edge of the earth’s curvature when viewing close to the surface of water.
What must be the angle of incidence for total internal reflection to occur? Let medium 1 be the medium with the higher index of refraction. As θ1 increases, θ2 also increases, albeit at a faster rate. When θ2 reaches 90 degrees, there is total internal reflection, and there is no transmission of light. The corresponding angle of incidence, θ1, is the critical angle where total internal reflection occurs. Let the critical angle be θc. Substituting into Snell’s law:
63) In a second experiment Dr. Rowbotham affixed flags 5 feet high along the shoreline, one at every mile marker. Then using his telescope mounted at 5 feet just behind the first flag looked over the tops of all 6 flags which lined up in a perfectly straight line. If the Earth were a ball 25,000 miles in circumference the flags should have progressively dipped down after the first establishing line of sight, the second would have descended 8 inches, 32 inches for the third, 6 feet for the fourth, 10 feet 8 inches for the fifth, and 16 feet 8 inches for the sixth.

Keep up the good work Eric, you have alot of evidence to back up your claims of Flat Earth. I now can clearly see we have been lied to for over 500 years. Science today is propaganda for manipulation, all these new age science movements are just a another religion. This explains how indigenous tribes around the world knew astrology without the use of telescopes. The planet or plane we live on is the only physical dense place in this universe. NASA has never been in outer space because it doesnt exist. I cant wait until more people see through the lies, seems like everthing we been taught are lies. We call our selves today a so called advanced civilization but in my opinion the ancient civilizations who relied more on spiritual technology were way advanced. I can say the ones in power have played the biggest magic trick on humanity. There alot more mysterious with this flat earth to find.

do you think the UN earth projection is accurate or is it hiding anything......also is there a possibility that antarctica is another continent lying off the coast of south america distinct from the the so called outer ice wall boundary......i found a chinese map which projects the earth from the north pole but is oval rather than circular and includes antarctica as a continent off south america and literally on the opposite end is australia.......this map shows china wanting to have polar shipping routes through the Bering Strait to connect with ports in Northern Europe and North America.......cheers
The ancient Hebrew view of the earth was of a flat earth with a glass firmament that separated the “waters below” from the “waters above” (Gen. 1:6-7; Job 37:28), and in which the sun and moon were placed and had their daily circuit around and above the Flat earth (Gen. 1:14-18; Joshua 10:13; Job 22:14). The earth did not move and was set on a firm foundation, on pillars in the waters of the “deep”, a great ocean underneath the flat earth (Gen. 1:2; 1 Samuel 2:8; 1 Chronicles 16:30; Psalm 104:5; Proverbs 8:28-29). They did not believe in a spinning globe. If the false globe ideas were taught in ancient times, they were taught by the Babylonian Pagans, not God’s people.
Astronomers tell us that, in consequence of the Earth's "rotundity," the perpendicular walls of buildings are, nowhere, parallel, and that even the walls of houses on opposite sides of a street are not! But, since all observation fails to find any evidence of this want of parallelism which theory demands, the idea must be renounced as being absurd and in opposition to all well-known facts. This is a proof that the Earth is not a globe.
