Mystery of the Antarctica 'gravity hole' finally cracked by scientists
Antarctica sits above the strongest negative gravity anomaly on Earth, a region where the planet’s gravitational pull dips so ...
Earth, in most renderings, is a smooth sphere with a glossy complexion—a blue marble, as pictures snapped from space have shown us. Earth scientists know that’s not exactly true. Earth, in fact, is an ...
A mysterious gravity dip beneath Antarctica is growing stronger, shaped by deep Earth forces over millions of years.
