Antarctica’s Gravity Hole Growing Stronger, Scientists Find

Scientists discovered that Antarctica's "gravity hole" — a massive depression where gravity is weaker than normal — has been strengthening over 70 million years due to deep rock movements beneath the ice. Using earthquake data like a planetary CT scan, researchers found this gravity shift coincided with major climate changes and glacier formation that affected global sea levels and ocean chemistry. The findings suggest Earth's interior movements may influence ice sheet growth and stability, potentially offering new insights into climate systems.
