Phys.org / Antarctica sits above Earth's strongest 'gravity hole.' Now we know how it got that way

Gravity feels reliable—stable and consistent enough to count on. But reality is far stranger than our intuition. In truth, the strength of gravity varies over Earth's surface. And it is weakest beneath the frozen continent ...
