Perhaps the moon was formed instantaneously after a massive impact

New research suggests that instead of creating a sheet of orbital debris and the gradual formation of the Moon, a massive impact may have directly placed a Moon-sized mass in orbit. This new hypothesis for the formation of the moon has been shown by a very detailed computer simulation of the Computational Cosmology Institute of Durham University, and its results were published on October 4 (11 September) in the Astrophysical Journal Letters. Letters) has been published.

According to this possibility, which is rightly called the "Immediate-Satellite Scenario", the early moon was less molten during its formation process, and this suggests that more Parts of this moon formed immediately after a massive impact with Earth.

This faster formation theory also suggests a different internal composition for the moon, which could explain some of the strange Earth-like features found in The given examples of the moon can be seen.

The moon is thought to have formed about 4.5 billion years ago, when the Earth collided with a space body the size of Mars. Kurdish has been formed. An object that scientists call "Theia". Previously, this theory was proposed that the impact of the planet Theia caused a mass of debris to be thrown, from which the moon was gradually formed. . This idea was challenged when scientists discovered that the moon's rocks have a composition very similar to Earth's mantle.

High-resolution results obtained in a new simulation of the moon's formation, thanks to the impressive computing power of the Compact Memory Service. "DiRAC" (DiRAC) called "COSMA" at the University of Durham, England, has been made possible and shows that the outer layer of the moon is rich in material of terrestrial origin.

Thus, such an object could not only survive tidal forces. but it can even be driven into a higher orbit and save it from the risk of destruction in the future by such forces. "We went into this project not knowing exactly what the results of these very high-resolution simulations would be," he said. is leading to wrong answers, it was very exciting that according to the new results a moon like the moon can be placed in orbit. This approach provides us with a completely new range of possible places for the beginning of the moon's evolution."
