There's a gravity hole in the Indian Ocean, where ocean levels are about 300 feet lower than surrounding areas.
The gravity hole may have been caused by an ancient ocean bed that sank millions of years ago.
But a new study suggests researchers should have been looking around, not under, the gravity hole to solve the mystery of how it formed.
The blue dot over the Indian Ocean is a gravity 'hole' that has scientists baffled.
But scientists have struggled to explain the gravity hole in the Indian Ocean, known as the Indian Ocean geoid low.
