From GPS satellites to airline navigation, this field provides the mathematical framework that proves Earth is an oblate spheroid, not a flat plane. Here’s how real-world data—rather than ...

For many centuries a wealth of scientific evidence has demonstrated that the Earth is a sphere. Despite this overwhelming proof from the fields of physics, astronomy and even everyday observations ...

Although our world is definitely not flat, it’s not a perfect sphere either. The fancy name for the shape of the Earth is an oblate spheroid, meaning that it bulges around the equator.

Last week, the Sphere transformed into a giant basketball for the NBA Summer League, but has also been spotted looking like the moon, Earth, and even a giant eye. If you have photos you’d like ...
