A previously unexplained isotopic ratio may represent the echoes of the ancient Earth, which existed prior to the proposed Theia collision 4.5 billion years ago. A research team has analyzed the ratios of noble gas isotopes from deep within Earth's mantle, and has compared these results to isotope ratios closer to the surface. The found that 3He to 22Ne ratio from the shallow mantle is significantly higher than the equivalent ratio in the deep mantle.
