The Existing Frameworks of Delivery of Major Volatiles and the Feasibility of Mars-Mass Planetary Embryos as the Major Volatile Contributors to Bulk Silicate Earth.

Summary: How did Earth get the ingredients for life? Elements like carbon, hydrogen, nitrogen, and sulfur are absolutely essential for living things to exist. For years, scientists have debated exactly how these important "volatiles" arrived on our rocky planet. One very popular idea is that a giant, Mars-sized planet crashed into Earth billions of years ago, delivering these crucial ingredients all at once.

This study looks closely at that giant crash theory. By using chemical computer models, researchers figured out how these life-giving elements could have been stored inside the core, the bubbling magma, and the atmosphere of that ancient Mars-sized planet before it collided with Earth.
