Simulations suggest an alternative variant of the formation of the moon by collision

Durham (UK) – New Supercomputer simulations suggest an alternative way our moon formed by colliding with a Mars-sized body. So a huge impact could have formed on the early Earth and put the moon into orbit much faster than last models. The new scenario also explains last moon puzzle.

With the super computer DIRAC Memory intense maintenance (“COSMA”) at the University of Durham, Drs. Jacob cone rice and his team hundreds more different Impact scenarios with different Velocity, masses and rotational velocities of the two colliding bodies are simulated and verified which scenario the current earth-moon system result comes closest. the Results of the new simulations, the scientists at the “53e lunar and planetary science Conference‘and in the news’astrophysical log lettersto publish.

The extra massive computing power shows that lower resolution simulations Absolute important aspects of such violent clashes can be overlooked. “Only the high-resolution simulations produced lunar-like satellites with outer planetary layers richer in early Earth material — like our earth moon.”

Has the Moon collected from the rubble immediately after such a massive impact, the researchers say it could also mean that it melted less during its formation than previous standard theories suggest, according to which the Moon formed in and out of a disk of debris around the young Earth.

background
so far research assumes that Moon about 4.5 billion years ago by a crash of an object the size of Mars (Theia) originated. In most of this scenario constructive theories formed the Moon then after and after and for extended periods of time by the accumulation of orbiting debris from this crash. This one scenario is becoming but from the analysis of moon rocks in question posed, show this one yetthat its composition corresponds to that of the Earth’s mantle. Capture previous scenarios of such a collision but close that moon actually mainly from the rubble Theias should exist.

“The path of formation now shown could also explain the striking similarities between the isotopic composition of moon rocks and the Earth’s mantle,” explains the co-author of the study. Study, Vincent Eke. “It could also have observable effects on the thickness of the lunar crust, giving us even more precision to determine the exact nature of this collision.”

also the new ones Simulations that even as a natural satellite the Soil so that happened to you actually would expect to be torn apart by the tidal forces of gravity, this body didn’t make this approach alone survive, but would also be pushed into another orbit where it would be protected from future destruction by collision with the Soil would be safe.

The new scenario of a directly created satellites opens now new ones Possibilities for the original lunar orbit and the predicted composition and internal structure of the moon.
