Long bridges over the ocean, some 10 miles long, some 20 miles long, if you were to throw a laser level on a bridge, it would appear perfectly level clear to the horizon. Many people are noticing this phenomenon of the "flat earth" but are taking it to an extreme. (Bridges over 20 mile stretches of ocean from island to island may disappear out of sight like looking across an infinity-edge pool, but those bridges are built while taking the curve of Earth's surface under consideration, EVEN THOUGH a laser level shows it to be straight and flat. What's the deal?)
Earth's gravity bends the line of sight around the curve of the Earth so that it appears flat. The long bridges over ocean between islands for example, they may appear perfectly level, but they are actually built and MUST be built with taking the curvature of Earth's surface under consideration; the bridges are built, calculated to match the curve of Earth's surface, regardless if line-of-sight is level or not.
The horizon is level for so many miles before suddenly dropping off the "edge." THE HORIZON RISES TO EYE-LEVEL. You can see the distant horizon of the ocean at eye-level, and ships will sail out and then suddenly disappear over the edge. In some cases, like in Hawaii, the horizon of the ocean is OVER eye-level. People claim the Earth is flat. But, there is something else going on.
Eclipses too have this peculiarity. When the Earth is between the sun and the moon, during a lunar eclipse where the sun and moon are at the horizon, it has been observed that the sun on one side of the horizon and the moon on the other, are slightly above the level horizon-line. There is a gravity-warped level plane to contend with, where the sun and moon are above a flat and level distance of line-of-sight.
Let me explain this: If the horizon is at eye-level for so many miles, over a considerable distance, then the sun and moon appear over the horizon line during a lunar eclipse. Why does this happen when the sun and moon should be on opposite sides of the planet Earth, and how are we magically able to see around the curve of Earth to see the sun and moon during lunar eclipse, and how are we able to see a supposedly curved surface of Earth instead actually measuring to be flat and level?
The answer to this question is: Earth has a gravity lens.
A gravity lens is detected when during a solar eclipse, the constellation patterns are distorted around the sun. During the eclipse, the stars can be seen because the light from the sun is eclipsed. Stars that should be behind the sun are off to the side; stars that are just off to the side of the sun appear more out to the side of the sun.
Mercury also when it disappears around behind the sun, appears sooner than it should around from behind the sun because of the sun's gravity lens bending the light around the sun. We therefore see the light from Mercury while Mercury is still behind the sun.
Gravity lenses are able to magnify distant galaxies. It's common practice that Astronomers wait for a distant galaxy to line up or be very close to a star, so that the star's gravity will actually magnify the distant galaxy so astronomers can get a better and closer look.
The Earth's gravity lens acts in the same way, bending light around the curve of Earth so the light we see actually looks straight and level, however as said at the top, bridges built over long distances of flat ocean must be built with the curvature of Earth calculated in to the bridge construction.
This is what's known as "The Flat Earth."
The horizon of Earth rises to eye-level even at a considerable height over the surface of Earth.
There are many videos and photos and experiments done by people to prove and measure this. The famous experiments have been conducted with weather balloon tests which send a camera up around 25 miles in the air. The balloon falls to the ground later and the camera is recovered and it can be seen the horizon of Earth's surface rises to eye-level.
This phenomena of Earth's gravity lens has led many people to fanciful models of a flat Earth which just do not work in reality. An easy internet search will show the evidence, and there is a LOT of information about the flat Earth, but just a small percentage of it is actually true.
This page examines in detail what is going on with the Earth, and why people believe the Earth is flat, when the Earth is in reality, a spherical shape. After all, even during the lunar eclipse, the Earth's curve can be seen eclipsing the moon, even if the sun and moon are above the level horizon-line.
In order to understand the true nature of the heliocentric model of Earth, the paradox of flat and round Earth must be unified to be solved.
The problem is that the flat Earthers don't understand or believe in gravity, and the round Earthers don't understand the nature of Earth's gravity lens which actually DOES INDEED flatten the horizon we see while standing on Earth. The articles below this go into a lot of detail to illustrate and explain what's going on.
It's not some grand conspiracy to hide the truth, nor is it a grand deception, although it IS a grand illusion, albeit an optical one. When one understands gravity better, then one can speculate about how a different type of gravity lens can actually shorten the distance light can travel, much the same was as a photon takes both paths around a star. This entire website is dedicated to such a pursuit, of how to construct hyperdrive star ships (warp drive physics). This page is dedicated to "planetary relativity 101" so far.
When people are so lost as to not know the truth, and don't understand therefore don't believe in gravity or relativity, or frequency, then mainstream education has not done its job appropriately or correctly. It is ironic that the "Flat Earth" actually TOTALLY PROVES the existence of Gravity!
