According to a new study, the life on Earth was possible thanks to a collision between our world and an alien planet. As reported by the recent research, a Mars-sized space object crashed into Earth and seeded our planet with the organic matter needed for life to evolve. At the same time, the Moon was born, according to the scientists.
If we are to believe the classic theories on life on Earth, everything evolved on our dead planet thanks to ancient meteorite impacts which delivered organic matter such as carbon, nitrogen, and sulfur, among other chemical compounds. But, according to a new study, Earth collided with a Mars-sized space object which seeded our planet with the elements required for life to develop.
“Carbon and sulfur alone, unfortunately, cannot provide a solution to the origin of volatiles on Earth. What we show in the current work, is that when one considers carbon, nitrogen, and sulfur together, delivery via a giant impact or merger of the proto-Earth with a Mars-sized planet is the most likely solution,” explained Rajdeep Dasgupta from Rice University.
Life on Earth Emerged Thanks To A Collision Between Our World and An Alien Planet
“What they [the scientists from Rice University] found is that, when there is a lot of sulfur in the system, the element carbon behaves differently than nitrogen and doesn’t go into the metal [the simulated planet core] as readily, and can lead to a ratio of these elements that match the modern-day Earth’s ratio of these elements,” also said James Day from the Scripps Institution of Oceanography.
The scientists from the Rice University also established that upon the collision between Earth and a Mars-sized alien planet the Moon was born, besides that the impact seeded our planet with the elements responsible for life on Earth.
“Our study challenges the existing models of volatile element delivery methods. It also solves the long-standing problem that the volatile element ratios of the surface layers of Earth are distinctly different from the planet-forming building blocks that we know as chondrites,” said Rajdeep Dasgupta for Gizmodo.
