Scientists may have explained the solar system’s ‘Great Divide’

The video discusses the Great Divide in our solar system, which separates rocky planets from gas planets. Recent research from the University of Colorado, published in Nature Astronomy, explains that this divide may have originated from a massive ring structure around the Sun with alternating pressure bands. These bands separated matter, forming distinct planetary groups. The divide was not completely impenetrable, allowing carbon-rich materials to cross over, potentially influencing the evolution of life on Earth.

How did the pressure barrier affect the materials from outer space crossing the Great Divide?

In what way did the carbon-rich material that crossed the divide contribute to Earth's evolution?
