Can someone make me understand of Curvature feet calculation which is mentioned in several proofs. As in 71 number proof ( or several other distanced based proofs ) That the Observer distance is 60 miles sea-level from Chicago buildings which should be 2,400 feet below the horizon. As per Nasa earth curvature goes down 8 inches per mile. 72 inches(6 feet) and 60 miles contain 60 x 8 = (480 inches) that is equal to (480/12) = 40 feet. How does it count to 2,400 feet?

188) Over the years NASA has twice changed their story regarding the shape of the Earth. At first they maintained Earth was a perfect sphere, which later changed to an “oblate spheroid” flattened at the poles, and then changed again to being “pear-shaped” as the Southern hemisphere allegedly bulges out as well. Unfortunately for NASA, however, none of their official pictures show an oblate spheroid or pear-shaped Earth! All their pictures, contrary to their words, show a spherical (and clearly CGI fake) Earth.
"Parallels of latitude" only - of all imaginary lines on the surface of the Earth - are circles, which increase, progressively, from the northern centre to the southern circumference. The mariner's course in the direction of any one of these concentric circles is his longitude, the degrees of which INCREASE to such an extent beyond the equator (going southwards) that hundreds of vessels have been wrecked because of the false idea created by the untruthfulness of the charts and the globular theory together, causing the sailor to be continually getting out of his reckoning. With a map of the Earth in its true form all difficulty is done away with, and ships may be conducted anywhere with perfect safety. This, then, is a very important practical proof that the Earth is not a globe.

18.) The best possessions of man are his senses; and, when he uses them all, he will not be deceived in his survey of nature. It is only when some one faculty or other is neglected or abused that he is deluded. Every man in full command of his senses knows that a level surface is a flat or horizontal one; but astronomers tell us that the true level is the curved surface of a globe! They know that man requires a level surface on which to live, so they give him one in name which is not one in fact! Since this is the best that astronomers, with their theoretical science, can do for their fellow creatures – deceive them – it is clear that things are not as they say they are; and, in short, it is a proof that Earth is not a globe.

71) It is often possible to see the Chicago skyline from sea-level 60 miles away across Lake Michigan. In 2015 after photographer Joshua Nowicki photographed this phenomenon several news channels quickly claimed his picture to be a “superior mirage,” an atmospheric anomaly caused by temperature inversion. While these certainly do occur, the skyline in question was facing right-side up and clearly seen unlike a hazy illusory mirage, and on a ball-Earth 25,000 miles in circumference should be 2,400 feet below the horizon.
It is well known that the law, regulating the apparent decrease in the size of objects as we leave them in the distance (or as they leave us) is very different with luminous bodies from what it is in the case of those which are non-luminous. Sail past the light of a small lamp in a row-boat on a dark night, and it will seem to be no smaller when a mile off than it was when close to it. Proctor says, in speaking of the Sun: "his apparent size does not change!" - far off or near. And then he forgets the fact! Mr. Proctor tells us, subsequently, that, if the traveler goes so far south that the North Star appears on the horizon, "the Sun should therefore look much larger" - if the Earth were a plane! Therefore, he argues, "the path followed cannot have been the straight course," - but a curved one. Now, since it is nothing but common scientific trickery to bring forward, as an objection to stand in the way of a plane Earth, the non-appearance of a thing which has never been known to appear at all, it follows that, unless that which appears to be trickery were an accident, it was the only course open to the objector - to trick. (Mr. Proctor, in a letter to the "English Mechanic" for Oct. 20,1871, boasts of having turned a recent convert to the Zetetic Philosophy by telling him that his arguments were all very good, but that "it seems as though [Mark the language!] the sun ought to look nine times larger in summer." And Mr. Proctor concludes thus: "He saw, indeed, that, in his faith in "Parallax," he had "written himself down an ass.") Well, then: trickery or no trickery on the part of the objector, the objection is a counterfeit - a fraud - no valid objection at all; and it follows that the system which does not purge itself of these things is a rotten system, and the system which advocates, with Mr. Proctor at their head, a weapon to use - the Zetetic philosophy of "Parallax" - is destined to live! This is a proof that the Earth is not a globe.
I just watched a time lapse of the night sky that shows all the stars of heaven moving at once. This proves to me that they are something other than planets and suns far away. But I also noticed that there were really fast moving objects in the sky. Planes? meteors? I have looked up in the night sky and seen shooting stars. If its possible there is no ´´space´´, then what could they be? What are we really seeing when we look into the night sky?
 3) The natural physics of water is to find and maintain its level. If Earth were a giant sphere tilted, wobbling and hurdling through infinite space then truly flat, consistently level surfaces would not exist here. But since Earth is in fact an extended flat plane, this fundamental physical property of fluids finding and remaining level is consistent with experience and common sense.
The most commonly accepted explanation of this is that the space agencies of the world are involved in a conspiracy faking space travel and exploration. This likely began during the Cold War's 'Space Race', in which the USSR and USA were obsessed with beating each other into space to the point that each faked their accomplishments in an attempt to keep pace with the other's supposed achievements. Since the end of the Cold War, however, the conspiracy is most likely motivated by greed rather than political gains, and using only some of their funding to continue to fake space travel saves a lot of money to embezzle for themselves.
