Because of this, the planet\u2019s \u201cgravity surface\u201d, called the geoid \u2014 dips by about 120 meters compared to the global norm. This subtle dip influences ocean behavior, sea level measurements, and even how ice sheets evolve over time.&nbsp;<\/div>\n<div><\/div>\n<div>Recent research, including studies published in Scientific Reports, has helped scientists better understand what\u2019s causing it. The answer lies deep within Earth, far below the Antarctic ice.<br \/>\nXX<br \/>\nOver tens of millions of years, slow-moving currents in the mantle, the layer beneath Earth\u2019s crust, have shifted dense material around the planet. These movements, including sinking tectonic slabs, reduce mass in certain regions. Less mass means weaker gravity.&nbsp;<\/div>\n<div><\/div>\n<div>Models suggest this anomaly has existed for at least 70 million years, dating back to the age of dinosaurs. It became significantly more pronounced between 50 and 30 million years ago, a period that also saw major climate shifts and the formation of Antarctica\u2019s massive ice sheets. And importantly, it\u2019s still evolving today, just at an incredibly slow pace.&nbsp;<\/div>\n<div><\/div>\n<div>This isn\u2019t guesswork. Scientists used global earthquake data, advanced physics simulations, and reconstructions of Earth\u2019s interior to map the anomaly with increasing precision.&nbsp;<\/div>\n<div><\/div>\n<div>That being said, Antarctica does remain one of the most restricted and least explored places on Earth. Protected zones, such as the Antarctic Treaty System.<br \/>\nGiven that scientists now acknowledge the existence of a massive gravity anomaly, it raises questions about whether it could be linked to the hollow Earth theory, and prompts us to wonder what might truly lie hidden beneath the ice, beyond what is currently revealed to the public.<\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Yes, there really is a massive \u201cgravity hole\u201d under the ice, known as the Antarctic Geoid Low (AGL).
