Kern at the South Pole

(Image credit: The Gnome Experiment)Gravity, the force that draws objects together in proportion to their mass, varies depending on where you're standing on Earth. That's because our planet is not a perfect sphere with uniform density. With varying gravity, an object's weight also changes. Now scientists are charting these gravitational discrepancies with a jet-setting gnome whose weight is recorded at various spots across the globe.
