Our curved Earth also aligns perfectly with all of physics. Additionally, all of the other planets ever discovered also appear round, because that's how gravity likes things. I don't think this discussion is really about the actual evidence or the scientific process, however. 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.
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. 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. yoongi wearing from a collection that criticised our new age of spreading conspiracy like virus,, then mentioning how their authentic words were twisted for an online phenomena with zinger words like “old, stop group activities” by media,, there are dots that connect thereOn July 30, 2021, Shenzhou 12 astronaut Tang Hongbo photographed the spectacular scenery of thousands of lights in North Africa, clearly showing the curvature of Earth. (Image credit: Tang Hongbo/China Manned Space Engineering Office) To put it bluntly, we know more about the curvature of Earth than almost any other topic in the realm of physical science. There are so many experiments, observations and demonstrations that have, time and time again, revealed the curve of the Earth. 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. 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. But a fringe society founded in the 1950s, dedicated to insisting that the Earth is flat, has given rise to a modern ground of flat Earth adherents. These believers claim that the Earth is a flat disc, and that evidence that it is round — say, pictures taken from space — are an elaborate hoax involving multiple governments. Opinions differ on exactly how the flat Earth works, with believers concocting elaborate versions of physics and creative interpretations of the solar system to make their theories work.
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. You can learn more about the first photographs that clearly showed Earth's curvature in this NASA story. This explainer from Arizona State University lays out clearly and concisely the plentiful evidence for our planet's spherical shape. (Nearly spherical, rather: Earth's rotation causes it to be slightly squashed at the poles and swollen at the equator, a shape known as an oblate spheroid.) And this piece by fivethirtyeight.com explains why people believe in conspiracy theories such as the flat-Earth idea. Bibliography By claiming that Earth is flat, people are really expressing a deep distrust of scientists and science itself. 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.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. And that's not to mention the countless photos of Earth taken by orbiting satellites and eyewitness testimonies from astronauts hailing from dozens of different countries, space programs and private organizations. Many people don’t trust the society around them, most notably the representatives of that society. That trust often falls even further when it comes to elite representatives of that society, which include government officials, members of academia and scientists like me. 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.
