Basics of Round Earth (Heliocentrism) compared to Flat Earth (Geocentrism)
Helio-H vs Geo-G
1. Shape
H: Earth is a globe which rotates 1000 mph and orbits the sun at 66,600 mph.
G: Earth is a motionless plane and is embedded in the infinite plane of the universe, similar in form to a puddle on a prairie, an oasis in a desert, an island in the oceans.
2. Space
H: Earth moves with its solar system at .5 million mph in a limitless expanse called outer space; air pressure is nil, in effect a vacuum.
G: Earth is covered with one or more domes, aka the Firmament, beginning at the Karman line 62 miles above the surface.
3. Cosmology
H: Earth is a planet which spirals around a star in an elliptical orbit; the universe consists of other stars which traverse the universe and travel millions of miles each day.
G: Earth is a vast and irregular plane of lands and oceans which are bounded by an ice wall called Antarctica; stars and the sun and moon circle overhead and are possibly plasma manifestations in or adjacent to the dome.
4. Gravity
H: Science declares that a force called gravity prevents matter from being thrown off earth due to the spin of the globe and centrifugal force; gravity also causes ocean waters to seek their own level by curving to match earth's rotundity.
G: The definition of gravity is "weight"; particle density is a property of matter; clouds are aerosolized water vapor and float because they are lighter-than-air; liquid water is heavier-than-air and falls as rain; other substances accumulate in layers based on their relative densities.
5. Math
H: Earth is a sphere about 8,000 miles in diameter; spherical trigonometry arrives at a formula for curvature at 8 inches per distance mile squared, or 8x(dxd). So adjusting for observer height, there will be a drop of 8 inches over one mile. For 2 miles the drop will be 8 inches times 2 squared, or 32 inches.
3 miles = 8x(dxd) = 8x9=72 inches = 6 feet
G: Earth is a plane which varies in altitude in mountains, valleys, and other natural features; long distance targets are visible in clear weather when zoom and/or infrared lenses are applied.
