Apr 12, 2007 · Isaac Newton first proposed that Earth was not perfectly round. Instead, he suggested it was an oblate spheroid—a sphere that is squashed at its poles and swollen at the equator.

Dec 5, 2022 · Based on our research, we rate FALSE the claim that an image of Chicago's skyline taken in Indiana proves the Earth is flat. Scientists say the post’s calculations are incorrect and the photo...

Nov 24, 2017 · At right around 12,700 kilometers (7,900 miles) in diameter, our world is undoubtedly a sphere. But what if you had never been to space, or high enough up to see the Earth's curvature yourself?

Making stellar observations from a representative set of points across Earth, combined with knowing the shortest on-the-ground distance between any two given points, makes an approximate sphere the only possible shape for Earth.

Mar 3, 2023 · We have abundant evidence going back thousands of years that the Earth is roughly spherical. A post on Instagram claims that balloons spotted in the sky above North America last month are evidence that satellites are “fake”. A caption on the post says: “Earth is flat and satellites are fake”. This is not true. Man-made satellites are real.

Spherical Earth or Earth's curvature refers to the approximation of the figure of the Earth to a sphere. The concept of a spherical Earth gradually displaced earlier beliefs in a flat Earth during classical antiquity and the Middle Ages.

It is not difficult to know that the Earth is round. In fact, people have known of this for way more than 2,000 years. The ancient Greeks actually had a number of really elegant, wonderful proofs...

Apr 3, 2022 · Rather than a perfect sphere, Earth is "oblate," meaning it's shaped like a slightly flattened sphere. In fact, "most planets and moons are not true spheres; they are usually squished in some...

Nov 16, 2023 · While we know the Earth is round, it isn’t a perfect sphere. Instead of being a perfect sphere, the earth is wider at certain points. There are many factors responsible for the irregular sphere shape of the Earth. They include centrifugal force, …

Dec 27, 2021 · A sphere is a perfectly round 3-dimensional object. Earth is like a big bag of molten lava spinning on its axis. Because of the “bulging” caused by the Earth spinning, the Earth is not completely round, thus, is not a sphere. Instead, we use the term “oblate spheroid,” or …
