Over the years we have lived with the believe that our earth is spherical in shape. This misinformation was given by the agencies in charge starting from the time there were little or no technology to proof further truth.
Pythagoras based his evidence on the shape of the terminator(the line between the part of the moon in the light and the part of the moon in the dark) as it moves through its orbital circle. He further added that since the moon is round, therefore the earth is round as well. Afterwards, between 500 B.C and 430 B.C, a fellow called Anaxagoras established that the true cause of solar and lunar eclipses illustrates the shape of the earth.He explains that the shape of the earth's shadow on the moon during the above event proof that the earth is round.
in 350 B.C , the great Aristotle also stated that the earth was sphere basing his observation on the constellations you could see in the sky when you travel further and further away from the equator.
From the above observation we have realized that there evidence was based on assumption .
The claims that the earth is round has been described as the ultimate conspiracy theory in history.Recent technology has proven that the earth a disc with the arctic circle in the center. And Antarctica, a 150 foot tall wall of ice around the rim .NASSA employees they say guard this ice wall to prevent people from climbing over and falling off the disc.
Thompson, founder of the official flat earth and globe discussion page shouted that he had proof the earth is flat apparently saying an astronaut drowning was a proof and that NASSA is lying about the flat earth theory.
