New supercomputer simulations show that nearly a billion. How could the Moon be formed by a collision of the Earth with a Mars-sized planet called Thea billions of years ago.
Scientists in the UK have produced several animations of simulation scenes, each showing a different amount of spiral ‘wandering planets’, approaching Earth.
Each simulation depicts various explosive patterns of rocky detritus emanating from the point of impact, which eventually climbed to form the moon.
These simulations are based on what astronomers commonly know as the ‘Big Splash’ theory or the ‘wide-impact hypothesis’.
According to the theory, ia, with a diameter of 79177 miles, broke on Earth with a diameter of 91 miles, forming a ring of debris around our home planet which eventually came together to form the moon.
This phenomenon – about 45.4545 billion years ago and 1 million million years after the formation of the solar system – is the most comprehensive idea to explain how large the moon is compared to other rocky bodies.

Still images of the cross section of a 3D simulation run by researchers are investigating how the collision between an early-Earth and a Mars-sized object object led to the formation of the moon.
‘Collision Animation’ shows the effect with non-spinning thea. It’s the sames ‘Impactor without spin’ but separately Point of view.
‘By adding different amounts of spin to thea in simulations, or even if there is no spin, it gives you a whole range of different results for what would have happened billions of years ago, when it was struck by a large object on the early Earth. , ‘Said Sergio Ruiz-Bonilla, study author at Durham University.
‘It is exciting that some of our simulations have produced this orbital cluster of material not less than the Moon, with additional material disks around the Earth after orbit, which will help the difficulty to grow in mass over time.
‘I wouldn’t say this is the moon, but it’s definitely a very interesting place to keep looking.’
In partnership with the University of Glasgow, Durham scientists conducted their supercomputer computer simulation at the DRAC high-performance computing facility.
DRAC’s computing resources – a vast collection of processors, wires and other hardware – are distributed at four university sites, including Durham.
Researchers found rocky material that would have exploded from the source of the collision and possibly formed the moon.
The corresponding collision with the initial earth produced different results depending on the size and direction of Thia’s initial spin, from spinning both clockwise and counter-clockwise to ‘spinning like a pool ball’.
At one extreme, with maximum spin in a clockwise direction, the collision merged the two objects together.
With the maximum spin running counterclockwise, meanwhile, there was a grazing ‘hit-and-run’ effect.
Graphic from research paper. The yellow planet is Thea and the black arrows represent their different spinning rates. The two left ones (l = -1 / 2 and l = -1 / 4) resulted in a merger. The middle box x (showing simulations associated with a spin) and the clamps or lunar candidates on the right side of it were rotated.

And the simulation where no spin was added to the thea produced a mass of self-gravity of the material with about 80 percent of the lunar mass.
When a small amount of spin was added to the simulations, another lunar-like object was created.
The resulting finesse, which was shown to stabilize in orbit around the Earth after the impact, will be grown by clearing debris of debris around our planet.
The simulated lump also had a small iron core, similar to the moon, with an outer layer of material made of early earth and thea.
In this artist’s imagination the collision with the Earth may be similar to the Thea in a scene that shows the celestial body about the size of the body of our lunar planet.
“We get a lot of different results depending on whether or not we introduce spin before the Earth collapses,” said Dr Vincent Ke K, a study author at the University of Durham.
‘It is particularly interesting that when no spin or very little spin is added to the thea, the effect with the initial earth leaves debris behind, which in some cases involves a body worthy of being known as the proto-moon.
‘There could be a lot of potential collisions that are still pending that could bring us even closer to understanding how the moon was formed in the first place.’
While the simulations are not conclusive evidence of the moon’s origin, the experts added that they represent a promising platform for understanding how our closest neighbors could be formed.
Research conducted in March this year has claimed to prove the Big Splash theory, based on the traces of Thea in lunar rocks.
Researchers at the University of New Mexico have examined oxygen isotopes in lunar rocks brought back to Earth by Apollo astronauts.
They found differences in oxygen isotopes – an indicator of the origin of matter – between lunar rocks and Earth rocks, which may have come from the remnants of Thea after impact.
However, another study in May reported the discovery of carbon ions from the lunar surface.
This image of the moon was taken by NASA’s Galileo spacecraft on December 7, 1992 while exploring the Jupiter system in 1995-97.
Carbon should evaporate completely by the intense temperature generated in the event of a heavy impact.
The findings of this new study are published in the Journal Monthly Notice of the Royal Astronomical Society.
The research team now plans to run more simulations by changing the mass, speed and spinning rate of both target and effective to see what effect it has on the potential lunar formation.
Scientists may not agree on how the moon formed, but many believe it was a vague result from the effects of the Earth and any other plant.
Many researchers believe that the Moon was formed billions of years ago after Mars was sized by Earth.
This is called the giant impact hypothesis.
Theory suggests that the moon is about a billion. It is made up of debris left after a collision between our planet and our body billions of years ago.
The colliding body is sometimes called Thea, after the mythical Greek Titan, who was the mother of the moon goddess, Celine.

But one mystery remains, Apollo astronauts revealed by the rocks brought back from the moon: why are the moon and the earth so similar in their composition?
Different theories have emerged over the years to explain the identical fingerprints of the Earth and the Moon.
Perhaps the effect created a huge cloud of debris that merged completely with the earth and later condensed to form the moon.
Or theia, coincidentally, could be chemically similar to the young earth.
The third possibility is that the moon is formed from clay objects instead of thea, although this effect would be of a very unusual kind.
