That region is known as the "Indian Ocean Geoid Low" the lowest gravitational potential on Earth's surface. Here's a quick breakdown:
🔹 Why is gravity weaker?
The anomaly is likely due to ancient tectonic activity. Around XX million years ago, a huge mass of cooler, denser material sank into Earth’s mantle beneath the Indian Ocean. This causes less gravitational pull in the area, lowering local sea levels by about XXX meters.
🔹 What’s a geoid?
It’s the hypothetical shape of Earth’s oceans under the influence of gravity and Earth’s rotation alone (no tides or winds). The Sri Lanka anomaly is the deepest dip in this “gravity sea level.”
🔹 Real-world impact?
Satellite data must account for this anomaly for precise navigation, oceanography, and climate science. It's a hidden but vital feature of Earth's gravitational field.
So yes gravity isn’t uniform, and in this case, it has literally pulled the ocean down.
