Scientists recreate Earth's early years with new simulation

A new computer model reveals the dramatic early history of Earth after its formation 4.5 billion years ago.

Revolutionary Insights Into Early Earth From New Simulation

Researchers have recreated the surface of Earth just after its formation 4.5 billion years ago using a new computer model called the Bambari model. This simulation offers insight into the planet's molten state, uncovering how uneven cooling shaped its geological structure. During this time, Earth's surface was a liquid rock mass, cooling over millions of years. The `basal magma ocean`, a significant feature of this state, played a crucial role in the planet's thermal history and the development of its mantle. This model highlights the surprising presence of minerals deep within the mantle, suggesting a complex evolution of the planet’s interior and its connections to volcanic activity today.

The insights from this simulation not only provide a clearer picture of Earth's formative years but also challenge long-held beliefs about the planet's internal structure. The discovery of unexpected minerals in the mantle reshapes our understanding of Earth's geology and the processes that have influenced it. This research has implications beyond Earth, potentially offering clues about the formation of other rocky planets in our solar system and beyond. The ties between Earth's early liquid state and its current geological features point to a rich history that continues to shape our planet today.
