The simulations showed that the gravity hole was initially much less pronounced. Between roughly 50 million and 30 million years ago, however, it intensified significantly. This period coincides with ...

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 persistent "gravity hole" beneath Antarctica gives scientists a window into Earth's deep interior, showing how processes far below reshape the planet's gravity field over millions of years.
