The “gravity hole” in East Antarctica formed at least 70 million years ago after convection in Earth’s mantle. The weak gravity could impact our oceans.

We tend to think of gravity as being about as constant as it gets. It is the invisible anchor that keeps our feet on the ground and the oceans in their beds. But if you look closely enough — and deep ...

Forte and colleagues now believe Antarctica’s gravity hole was weaker before eventually intensifying around 30 to 50 million years ago. This corresponds to large-scale changes in the continent’s ...

A vast “gravity hole” beneath Antarctica became stronger as the continent shifted into an ice-dominated world tens of millions of years ago, according to new research published in Scientific Reports.

After accounting for Earth’s rotation, gravity is slightly weaker beneath Antarctica than anywhere else on the planet. That weakness creates a kind of “gravity hole,” a broad low in the field that ...

Something wasn’t making sense—and then scientists realized they were looking in the wrong place.
