Unraveling the Mystery of the Indian Ocean's Gravity Hole

Scientists have used supercomputers to simulate the formation of the "gravity hole" in the Indian Ocean, a depression that experiences less gravity than the rest of the planet. The study suggests that the cause of the gravity hole is likely due to plumes of magma under the Earth's crust, formed by the drifting and collision of India's subcontinent with Asia 40 million years ago. The researchers ran simulations dating back 140 million years, with six of them leading to the formation of the gravity hole. However, some experts argue that the study fails to account for certain factors and that the simulated geoid differs from Earth's real surface shape.
