• •A gravity anomaly beneath Antarctica, known as the Antarctic Geoid Low, is being used to track deep-Earth changes.
• •Scientists reconstructed the evolution of this gravity anomaly over 70 million years, revealing its persistence and changes.
• •The anomaly is linked to slow-moving processes within Earth's mantle, offering insights into how the planet's gravity field reshapes over time.
• •The study has implications for understanding planetary science, including the internal dynamics of Mars and Venus.
