a team of scientists in Britain have found that, now the earth is not ancient, ancient earth already caved in because of certain events.
scientists found deep in the earth, isotope ratio anomaly chaos, there is, therefore, they think, this is evidence of ancient earth exists in the depths of the earth, and hit the earth 4.5 billion years ago the mars-sized planet is the culprit.But in the crash, the moon was born, and there is evidence that the core is that the earth had the impact of planets.
in the study, the scientists found that the collision of two planets only a small part of the ancient earth heat melting or scatters into space, and in the depths of the earth's mantle, are preserved ancient ruins the earth.
by rights, rare gas isotope ratio should be to the surface of the earth's interior of isotope ratio showed regular changes, but in the actual detection, scientists found deep in the earth's mantle helium 3 with neon 22 ratio is far lower than the upper mantle, the isotope ratio.Moreover, xenon 129 and 130 the ratio of the abnormal but also highlights the deep mantle source anomaly.
by physics we can know, xenon 129 is produced by iodine 129 for beta decay, through decay cycle of xenon 129 scientists calculate the depths of the earth's mantle, which is the oldest area should be in the earth's mantle that cohesion formed after the completion of one hundred million years.
the theory explains why a lot of earth area of the inert gas isotope ratio difference, before the problem already has baffled scientists for a long time.If it is correct, we will have the opportunity to see the "big impact" planet before the appearance of the ancient earth, explore the origin of life.
although we are still on the depths of the universe, the earth's interior, could not see one's own soul, don't understand the fate of life, but we never give up.
