Recent seismic studies have unveiled the presence of massive viscous BLOBs at the base of Earth’s mantle, a discovery that could potentially reshape our understanding of the planet’s deep interior structure. These intriguing structures, including two giant blobs that may influence Africa’s unusual geology, could be remnants of an ancient collision with the protoplanet Theia from an alien world. With the latest advancements in seismic anisotropy analysis, we are gaining fresh insights into these viscous BLOBs, and it seems that the mystery of these giant blobs deep inside Earth might finally be on the verge of being solved.
The Initial Discovery of Massive Viscous BLOBs
On October 22, 2025, scientists announced the discovery of massive viscous BLOBs at the base of Earth’s core. These BLOBs, positioned at the very base of our planet’s core, are characterized by their viscous nature, a key characteristic that sets them apart from other geological structures. The recency of this discovery underscores the ongoing nature of our exploration of Earth’s deep interior.
Seismic Anisotropy as a Key Investigative Tool
Seismic anisotropy, a method that measures variations in seismic wave velocities, has proven to be a crucial tool in investigating these viscous BLOBs. A report published on October 21, 2025, highlighted how seismic anisotropy provides insight into these structures at the base of Earth’s mantle. This method allowed researchers to study these BLOBs at the precise depth where they reside, furthering our understanding of their nature and composition.
Origins Linked to Protoplanet Theia
There’s a fascinating theory that suggests these blobs could be remnants of an alien world, specifically pieces of the protoplanet Theia. This hypothesis, published on November 13, 2023, proposes that these Theia remnants lurk deep inside Earth. If proven, this theory could provide a significant piece of the puzzle in understanding the formation of our planet and its complex geological history.
Solving the Mystery of Giant Blobs
In April 2025, a significant development suggested that the mystery of the “Giant Blobs” found deep inside Earth might be close to being solved. This report, published on April 18, 2025, focused on these giant blobs’ location deep inside Earth and addressed the unresolved questions surrounding their nature and origin. This marked a pivotal update in the timeline of our understanding of these intriguing structures.
Impact on Africa’s Weird Geology
Interestingly, these giant blobs may also explain some of the peculiarities of Africa’s geology. A study from March 12, 2022, suggested that two giant blobs in Earth’s mantle could be influencing Africa’s unique geological features. These blobs, located under the Earth’s mantle, seem to have a specific tie to African tectonic anomalies, providing a potential explanation for the continent’s weird geology.
Broader Implications for Earth’s Deep Structure
The discovery of these viscous BLOBs and the subsequent research into their nature and origins have broader implications for our understanding of Earth’s deep structure. The potential link to protoplanet Theia remnants could shed light on theories of Earth’s formation history. Furthermore, the viscosity of these giant blobs influences heat flow and convection patterns at the core-mantle boundary, which could have significant implications for our understanding of mantle dynamics and overall planetary composition.
