A vast gravitational anomaly beneath Antarctica—often described as a “gravity hole”—has long intrigued scientists and reshaped understanding of Earth’s internal structure. Located beneath the Antarctic ice sheet, this region exhibits a measurable dip in gravitational strength, detectable through satellite-based geophysical surveys. Recent advances in remote sensing and crustal modeling suggest that the anomaly is linked to ancient tectonic shifts and variations in mantle density rather than any literal cavity.
