Sea levels in this circular area are 348 feet lower than anywhere else on Earth. This is caused by a gravity anomaly, in this case, a very weak gravitational pull.
Although it was discovered in 1948, no one knows what created it. However, a study tried to understand where it came from in 2023 and made a surprising discovery.
According to this research, an ancient ocean called Tethys once existed between the supercontinents Laurasia and Gondwana. This death caused the formation of a gravity hole in the Indian Ocean.
This research was published in the journal Geophysical Research Letters. The hole stretches over 3.1 million square kilometers and is located 1,200 km southwest of India.
The researchers simulated the movement of the Earth’s mantle and tectonic plates over the past 140 million years and proposed several scenarios.
Tethys sank along with part of the Earth’s crust 180 million years ago. When Gondwana broke apart, the crust moved under the Eurasian plate. When this happens, pieces of the destroyed crust go deep into the mantle.
About 20 million years ago, these fragments were replaced by high-density material derived from the “African blob” after reaching the lower reaches of the mantle.
The blob is stuck under Africa and is 100 times taller than Mount Everest. The blob is formed by crystalline magma.
As pieces of low-density magma rise and replace the magma, the overall volume of the region decreases and its gravity weakens.
However, this research still needs to be supported by seismic data to help confirm the presence of low density plumes beneath the hole. It is believed that there are some flowers like this in the Earth’s magma, even where they should not be there.
Even Mars is reported to have such bumps beneath its surface. Understanding what happens beneath the Earth’s surface is also expected to help scientists learn more about the red planet.

How does the presence of a “gravity hole” challenge our current understanding of the Earth’s gravitational field and its uniformity?
## Unveiling Earth’s Deepest Gravity Hole: An Interview
**Introduction:**
Welcome to World Today News, where we delve into the wonders of our planet. Today, we’re joined by two esteemed experts to discuss the fascinating “gravity hole” found in the Indian Ocean – a unique anomaly with a history as deep as its lowered sea levels.
Joining us are Dr. EmilyCarter, a renowned geophysicist specializing in the Earth’s magnetic field and gravity, and Dr. Rohit Sharma, a geologist focusing on plate tectonics and continental drift. Welcome, both of you.
**Section 1: The Discovery and Nature of the Anomaly**
* Dr. Carter, the article mentions that this “gravity hole” was discovered in 1948. Could you elaborate on what initially led to its discovery and how we went from knowing about its existence to understanding its peculiar nature?
* Dr. Sharma, the article states that sea levels in this area are significantly lower compared to the rest of the world. Could you explain the connection between weakened gravity and this difference in sea level? How does this anomaly challenge our understanding of gravity’s influence?
**Section 2: The Tethys Ocean Hypothesis**
* Dr. Sharma, the research paper proposes a link between the “gravity hole” and the ancient Tethys Ocean. Can you walk us through this hypothesis and explain how the sinking of this ocean could have contributed to the formation of this gravitational anomaly?
* Dr. Carter, the article mentions the “African blob,” a massive geological structure deep beneath the Earth’s surface. How does the movement of this blob potentially relate to the “gravity hole”, and what evidence supports this connection?
**Section 3: Beyond Earth – Implications for Planetary Science**
* Dr. Carter, the article suggests that similar features might exist on Mars. How can studying this “gravity hole” on Earth provide insights into the geology and possible existence of similar anomalies on other planets?
* Dr. Sharma, the research highlights the need for further seismic data to confirm the presence of low-density magma plumes beneath the “gravity hole.” What other research avenues can be explored to gain a more comprehensive understanding of this phenomenon?
**Conclusion:**
This ”gravity hole” is a testament to the Earth’s dynamic and complex nature, offering a glimpse into the immense forces shaping our planet over millions of years. Thank you, Dr. Carter and Dr. Sharma, for sharing your expertise and shedding light on this remarkable scientific discovery.
We hope this discussion has piqued your interest and encourages you to learn more about the fascinating world beneath our feet.
**Note:**
This interview structure prioritizes open-ended questions to encourage detailed explanations and exploration of diverse perspectives. It aims to engage both experts and audiences while offering a comprehensive overview of the ”gravity hole” phenomenon.
