Antarctica is home to many mysteries, but one of the strangest is an enormous 'gravity hole' deep beneath the ice. The vast gravity hole, known as the Antarctic Geoid Low (AGL), is the product of incredibly slow rock movements, according to the experts. Scientists have known for years that there is a mysterious 'gravity hole' in Antarctica where the sea level is 420 feet (130 m) below the surrounding water. Once their predictions matched the best current data from gravity–sensing satellites, they wound back the clock and watched as the gravity hole formed over aeons. The Antarctic Geoid Low is not the only massive gravity hole on Earth.
