New simulation helps astronomers solve mystery of moon formation



[ad_1]

(MENAFN – Youm7) New supercomputer simulations have shown the possibility that the moon was formed by collision with Earth with a Mars-sized planet called Theia around 4.5 billion years ago, and British scientists have produced numerous animated simulation scenarios, each showing a different amount of rotation. The wandering planet, “Theia”, which could be his reward as he approaches Earth.

According to the theory, Theia collided with Earth’s 7,917 miles in diameter, creating a ring of debris around our home planet which eventually combined to form the moon.

The event – about 4.45 billion years ago and 150 million years ago after the formation of the solar system – is the most popular idea for how relatively large the moon is compared to other rock bodies, and adding varying amounts of spin to Theia in the simulations, or not having any spin on According to study author Sergio Ruiz-Bonilla, at Durham University, there is any a series of consequences different from what could happen when the early Earth collided with a massive object over all these billions of years.

Bonilla added, “It’s exciting that some of the simulations we’ve done have produced this orbital mass of material that is not relatively smaller than the moon, with a disk containing additional material around the Earth after the collision that will help mass to grow over time. I won’t say that’s all. ” The moon, but it’s definitely a very interesting place to look further. “

In partnership with the University of Glasgow, scientists in Durham have simulated their supercomputers in the DiRAC high-performance computing facility, and DiRAC’s computing resources – a wide range of processors, cables and other devices – are distributed at four campus sites, including Durham.

Researchers tracked rock material that allegedly exploded from the source of the collision and may have formed to form the moon. A simulated collision with early Earth produced different results depending on the size and direction of Theia’s initial rotation, from not spinning at all to “spinning like a billiard ball”, clockwise and counterclockwise. Clockwise.

At one end, with the maximum clockwise rotation, the collision merging the two objects together, and with the maximum anti-clockwise rotation, meanwhile there was a “hit and run” effect, and the simulation in which no rotation was added to Theia produced self-mass. The gravity of matter has a mass of about 80% that of the moon.

And when a small amount of rotation was added to the simulations, another moon-like object formed, and the resulting conglomerate, which turned out to be orbiting Earth after the collision, could develop into collecting the disk of debris surrounding our planet, and the simulated mass also had a core A small ferrite, similar to the core of the Moon, with an outer layer of material formed from early Earth and Theia.

Study author Dr Vincent Ike of Durham University said: “We get a number of different results depending on whether or not we introduce the spin to Theia before it crashes. in the early Earth. It’s especially amazing that if we don’t add a spin or so little to … As for Theia, the impact with the early Earth leaves behind a trail of debris, including in some cases an object large enough to deserve to be called the primordial moon. There may be a number of potential collisions that have not yet been investigated, which could bring us closer. To understand how the moon formed in the first place. “

While the simulations are not conclusive proof of the origin of the moon, they represent a promising step in understanding the formation of our closest neighbors, experts say, and the research claimed in March this year for prove the Big Splash theory, based on Theia’s effects in moon rocks, and researchers at the University of New Mexico are examining isotopes of oxygen in moon rocks, which were brought back to Earth by astronauts of Apollo.

They found differences in oxygen isotopes – an indication of the substance’s origin – between moon rocks and rocks on Earth, which could have come from Theia’s remains after the collision, however, another study in May reported the discovery of carbon ions on the surface of the moon.

The carbon was believed to have completely evaporated due to the extreme temperatures generated during the colossal collision, and the results of this new study were published in the Journal of Monthly Notices of the Royal Astronomical Society, and the research team predict now to conduct more simulations to modify the mass, speed and rate of rotation of the target and the collision. To see what effect this would have on the formation of the potential moon.
