Earth's chemistry settled early but later collision likely delivered water for life
Los Angeles CA (SPX) Sep 01, 2025 Earths chemical make-up reached completion within the first three million years of the Solar Systems formation, according to a new study by the University of Berns Institute of Geological Sciences. However, this early Earth, known as the proto-Earth, lacked volatile elements such as water and carbon compounds that are essential for life. The findings, published in Science Advances, suggest
The Earth would have been unable to shelter life without a major collision with Theia, a protoplanet of Mars size, more than 4 billion years ago, suggests a new study. The primitive Earth would have been located in a region of the solar system where temperatures were too high to condense the volatile compounds essential to the emergence of life. Theia, which would have formed further in the solar system, would then have brought these compounds a…
