What is known as the Giant Impact Hypothesis (which refers to the epic crash between Earth and Theia as the Giant Impact) has had an impact that goes beyond dense blobs that could bring down a satellite. The disembodied remains of Theia might have also contributed some iron to Earth’s cor...
Scientists have long agreed that the Moon formed when a protoplanet, called Theia, struck Earth in its infancy some 4.5 billion years ago. Now, a team of scientists has a provocative new proposal: Theia's remains can befound in two continent-size layers of rock buried deep in Earth's man...
Finally, although simulation uncertainties and a terrestrial contribution to Moon formation enhance the fraction of Theia analogs consistent with the canonical giant impact hypothesis, this fraction still remains in the 5–8% range.doi:10.1016/j.icarus.2015.06.019Kaib, Nathan A....
