One glaring mystery at the center of the moon's formation may be lie some 1,800 miles below Earth's surface, a new study suggests.into Earth as it was forming billions of years ago, spewing debris that coalesced into the moon that decorates our night sky today.
A new theory, however, suggests that remnants of the ancient planet remain partially intact, buried beneath our feet. These blobs are thousands of kilometers wide and likely more dense with iron compared with the surrounding mantle, making them stand out when measured by seismic waves. But the origins of the blobs — each of which is larger than the moon — remain a mystery to scientists.
Immediately, he began perusing scientific studies, searching to see whether someone else had proposed that LLVPs might be fragments of Theia. But no one had.“I was afraid of turning to other people because I afraid others would think I’m too crazy,” Yuan said.Yuan first proposed his idea in a paper he submitted in 2021. It was rejected three times. Peer reviewers said it lacked sufficient modeling from the giant impact.
In that environment, if the material that makes up the LLVPs was too dense, it wouldn’t be able to pile up in thethat it appears in, Desch said. And if it were low enough in density, it would simply mix in with the churning mantle. Dr. Seth Jacobson, an assistant professor of planetary science at Michigan State University, acknowledged that the theory may not, however, soon reach broad acceptance.
