10 simple proofs that the Earth is round
Posted: Sun Feb 02, 2025 10:56 am
People have known for a long time that the Earth is round, and they are finding new and new ways to show that our world is not flat. And yet, even in 2019, there are quite a few people on the planet who are firmly convinced that the Earth is not round. These are people who, as a rule, believe in conspiracy theories, and it is difficult to argue with them. But they exist. As is the “Flat Earth Society”. It becomes funny to think about the arguments they might have. But the history of our species has been interesting and tricky, even firmly established truths have been refuted. You don’t have to resort to complex formulas to dispel the flat Earth conspiracy theory.

Today, people already know that the Moon is not a piece of cheese or a playful deity, and the phenomenon of our satellite is well explained by modern science. But the ancient Greeks had no idea what it turkey number data was, and in their search for an answer, they made some insightful observations that allowed people to determine the shape of our planet.
Aristotle (who made quite a few observations about the spherical nature of the Earth) noticed that during lunar eclipses (when the Earth's orbit places the planet exactly between the Sun and the Moon, casting a shadow) the shadow on the lunar surface is round. This shadow is the Earth, and the shadow it casts directly indicates the spherical shape of the planet.
Ships and horizon
If you've been to a port recently, or just strolled along the beach, gazing at the horizon, you may have noticed a very interesting phenomenon: approaching ships don't just "appear" from the horizon (as they should if the world were flat), but rather emerge from the sea. The reason ships literally "emerge from the waves" is that our world is not flat, but round.
Imagine an ant walking along the surface of an orange. If you look at the orange from a close distance, nose to the fruit, you will see the ant's body slowly rise above the horizon of the curvature of the orange's surface. If you perform this experiment with a long path, the effect will be different: the ant will slowly "materialize" into your field of vision, depending on how sharp your eyesight is.
