A "gravity hole" beneath Antarctica is offering scientists a rare glimpse into Earth's deep interior, a dynamic record of slow-moving processes that have been reshaping our planet for tens of millions of years.
This immense, gentle low in Earth's gravity field, formally known as the Antarctic Geoid Low, reflects how mass is distributed deep inside the planet. In a new study led by researchers at the University of Florida, scientists reconstructed how this gravity anomaly has evolved over the past 70 million years, revealing the feature is not a fleeting oddity but a persistent, changing imprint of slow, powerful currents of rock churning thousands of miles beneath Antarctica.
