THE EARTH IS FLAT DIDN'T YOU KNOW THAT? T-Shirt

Product Information

During a lunar eclipse, Earth passes between the sun and the moon, allowing Earth to cast its shadow on the moon. That shadow is always, always, always a circle, no matter where you are on the planet, no matter the timing of the eclipse. Always. If the Earth were flat," Adhikari says, "the trajectory would be completely different." How different depends on which way the globe is sliced into a flattened map, but if it looked like it does on a Mercator-projection map, it might head east and pass over Africa. ARMYs feel that Suga chose the t-shirt for its satirical punch, which ended up creating a full-circle moment after BTS took a jab at their words being twisted by the media during the concert. Some also feel that the shirt ended up being complimentary to the controversial event that the concert itself had become over the past few months. The photograph showed the troposphere-stratosphere boundary and the actual curvature of the Earth and demonstrated the potential for long-range reconnaissance from high-altitude balloons," NASA officials wrote.

The Andes Mountains, 287 miles [462 kilometers] away, and although taller than the plane's altitude, lay below the sensible horizon, marked by the white horizontal line in the photograph," NASA officials wrote in a description of the flight. "The Earth's curvature explains this phenomenon, as described in the diagram accompanying the photograph. The Earth's curvature is also visible laterally in the photograph, although the effect is subtle as the image encompasses only 1/360 of the Earth's circumference." rod said:Helio, in your post #7, I know some flat earth folks. Conspiracy can play a role but for many, flat earth is empirical too. I have studied flat earth videos on measuring the distance to the Moon using telescopes, angles obtained, and plane trigonometry vs. spherical trigonometry. FE folks are correct like the Flat Earth Society. The Moon will always be much closer to the flat disk earth using plane trigonometry. At most the Moon is about 3400 miles away and about 0.5 degrees angular size, so much smaller in size too. I don't know the trig approach they use, nor care to spend time on it, but the parallax would be 75x greater for a 3400 mile distance than actual. Two telescopes relatively close together could see this. Only one falsification is needed to debunk their model, but hundreds exist. Finding one element to be correct and hundreds false is not a scientific model, even if one element is found. For instance, what’s the tallest supposed mountain on Earth? Everest. Except it isn’t. The name is a giveaway; it’s clearly a morphing of “never rest”, because if you wanted to go to the biggest mountain you’d literally never rest, because it isn’t actually there. What about all those people who have climbed it, you say? Well, consider all the people who have died supposedly doing so. How do you die climbing something that isn’t there? You can’t. They were obviously killed to protect the conspiracy, whereas those who “survived” were willing to play ball. Don't trust NASA? The Russians also snap pictures of the round Earth, Space.com reported. So does Japan's space agency. And China's. There’s no such thing as a mountain, they’re just optical illusions caused by light refracting off all the mind-altering chemicals in the air.

If you use gravity to, say, trust your GPS to give you accurate positions and calculate trajectories, then that same force will form material the size of Earth into a ball. The only way to always cast a circular shadow is if the thing casting the shadow — in this case, Earth — is a globe. It's a matter of geometry. Eric Oliver is a professor of Political Science at the University of Chicago. His research focuses on American politics, public opinion, political psychology, local politics, racial attitudes and self knowledge. He has published a number of books, the most recent of which was Enchanted America: How Intuition and Reason Divide Our Politics (The University of Chicago Press, 2018). He has also authored numerous articles in journals. Today the Earth is mostly solid with a liquid outer core, but when the planet was forming, some 4.5 billion years ago, it was very hot and behaved like more like a fluid—and was subject to the squishing effects of gravity. When you follow this train of logic, it becomes clear that the only feasible conclusion is that Earth is indeed flat. Flatter than anyone has ever expected.

Editor's note: This article was originally published on Sept. 8, 2020. An updated version was posted on Feb. 4, 2022. The ancient Greeks figured out that Earth was a sphere 2300 years ago by observing the planet's curved shadow during a lunar eclipse, when the Earth passes between the Sun and the Moon. Some flat-Earth believers claim the world is shaped like a disk, perhaps with a wall of ice along the outer rim. (Why no one has ever seen this supposed wall, let alone crashed into it, remains unexplained.) Wouldn't a disk-shaped Earth also cast a round shadow? Well, it would depend on the orientation of the disk. If sunlight just happened to hit the disk face-on, it would have a round shadow. But if light hit the disk edge-on, the shadow would be a thin, straight line. And if the light fell at an oblique angle, the shadow would be a football–shaped ellipse. We know the Earth is spinning, so it can't present one side toward the Sun time after time. What we observe during lunar eclipses is that the planet's shadow is always round, so its shape has to be spherical.You also experience the Earth's roundness every time you take a long-distance flight. Jetliners fly along the shortest path between any two cities. "We use flight paths that are calculated on the basis of the Earth being round," Adhikari says. Imagine a flight from New York to Sydney: It would typically head northwest, toward Alaska, then southwest toward Australia. On the map provided in your airline's in-flight magazine, that might look like a peculiar path. But wrap a piece of string around a globe, and you'll see that it’s the shortest possible route. And Earth's curvature is clearly apparent from high altitudes, as Capt. Albert Stevensof the U.S. Army Air Corps showed in the 1930s. In December 1930, for example, Stevens snapped a photo looking westward while flying at an altitude of 21,000 feet (6,400 meters) above Villa Mercedes, Argentina. The question of belief and sincerity is one that comes up a lot," Wilmore said. "If I had to guess, I would probably say that at least some of our members see the Flat Earth Society and Flat Earth Theory as a kind of epistemological exercise, whether as a critique of the scientific method or as a kind of 'solipsism for beginners.' There are also probably some who thought the certificate would be kind of funny to have on their wall. That being said, I know many members personally, and I am fully convinced of their belief." And in November 1935, Stevens and Capt. Orvil Anderson took a photo from a balloon that lifted off from Rapid City, South Dakota and soared to a maximum altitude of 72,395 feet (22,066 m). Engineers and architects also take the Earth's curvature into account when building large structures. A good example is the towers that support long suspension bridges such as the Verrazano Narrows bridge in New York City. Its towers are slightly out of parallel with each other, the tops being more than 1.5 inches further apart than their bases. If the Earth were flat, the bottom of the towers would be separated by the exact same distance as the top of the towers; the planet's curvature forces the tops of the towers apart.
