People tend to think of gravity here on Earth as a uniform and consistent thing. Stand anywhere on the globe, at any time of year, and you’ll feel the same downward pull of a single G. But in fact, Earth’s gravitational field is subject to variations that occur over time. This is due to a […]

What is bring done "for the first time ever"?

And now, for the first time ever, these variations have been captured in the image known as the “Potsdam Gravity Potato” –* a visualization of the Earth’s gravity field model produced by the German Research Center for Geophysics’ (GFZ) Helmholtz’s Center in Potsdam, Germany.

The article even shows a gravity map from 2005 that has the same potato shape.
