Those long, airport hallways are great places to have some fun with physics experiments. For example, could you measure the curvature of the Earth in the Atlanta's terminal A?

The first photographs documenting the Earth’s curvature were taken in the 1930s.

Scientists say the post’s logic is flawed and that radar technologies function on and account for the Earth’s curvature.

Earth is (always has been) round, so why have the flat-out wrong become so lively? Every fringe theorist needs an amplifier—used to be the penny press; today it's the Web.

Physics students from the University of Leicester have captured breathtaking images of the Earth's stratosphere using a high altitude weather balloon.

Next time a flat-earth conspiracy theorist confronts you, you'll be prepared. Here are 10 ways to prove that the Earth is round.

Dutch photographer and filmmaker Gerco de Ruijter has released a short film called Grid Corrections, which documents how straight street grids are bent to fit the curvature of the Earth.

The flat Earth conspiracy ignores the problems with its own claims and tries to open a debate that's been settled for more than 2,000 years.

At that altitude U-2 pilots, who have to wear full-pressure suits similar to those of astronauts that ensure survivability during depressurization, are able to see the curvature of the Earth and ...

Thomas Pesquet: Clouds and shadows and the curvature of Earth. Simple really, but so breathtaking! See how the camera lens used changes the shape of Earth’s curve? Les nuages et leurs ombres ...

The first photographs documenting the Earth’s curvature were taken in the 1930s.

Physics students have captured breathtaking images of Earth's stratosphere using a high altitude weather balloon. The unmanned balloon and sensor payload reached an altitude of 23.6 kilometers ...
