    The new research potentially plugs a big hole in the giant impact theory, long the leading explanation for the moon's formation. Previous versions of the theory held that the moon formed primarily ... More About The Giant Impactor Theory. In the mid-1970s, scientists proposed the giant impact scenario for the formation of the Moon. The idea was that an off-center impact of a roughly Mars-sized body with a young Earth could provide Earth with its fast initial spin, and eject enough debris into orbit to form the Moon.

    Forming a Moon with an Earth-like Composition via a Giant ...

    In the giant impact theory, the Moon formed from debris ejected into an Earth-orbiting disk by the collision of a large planet with the early Earth. Prior impact simulations predict that much of the disk material originates from the colliding planet. However, Earth and the Moon have essentially identical oxygen isotope compositions. This has been a challenge for the impact theory, because the ... Abstract: The giant impact hypothesis is the dominant theory of how the Earth-Moon system was formed. Models have been created that can produce a disk of debris with the proper mass and composition to create our Moon. Models have also been created which start with a disk of debris that eventually coalesces into a Moon. The impact theory explained many of the challenges about the formation of the Moon. For example, one question was: why do the Earth and Moon have very different-sized cores.

    A simulation of the Giant Impact hypothesis, which states the the Moon might have been formed from a collision between Earth and a Mars-sized body. The leading theory of the Moon's origin is the giant impact theory, which postulates that Earth was once hit by a planetoid the size of Mars; such a theory is able to explain the size and composition of the Moon, something not done by other theories of lunar formation.

    N-Body Simulation of the Formation of the Earth-Moon System from a Single Giant Impact Justin C. Eiland1, Travis C. Salzillo2, Brett H. Hokr3, Justin L. Highland3 & Bryant M. Wyatt2 Summary The giant impact hypothesis is the dominant theory of how the Earth-Moon system was formed. Models have In the context of the standard giant impact scenario (Stevenson, 1987, Canup, 2004b), the measured lunar composition places severe constraints on the composition of the impactor.The reason for this is that smooth-particle hydrodynamic (SPH) impact simulations that are successful in forming the Moon suggest that most (∼ 80%) of the material that is injected into orbit is derived from the ...

Only time will tell if his version of the Moon origin story will hold up to scrutiny. The study has been published in Nature. Wang et. al.

    Giant-impact hypothesis - Wikipedia

    The giant-impact hypothesis, sometimes called the Big Splash, or the Theia Impact suggests that the Moon formed out of the debris left over from a collision between Earth and an astronomical body the size of Mars, approximately 4.5 billion years ago, in the Hadean eon; about 20 to 100 million years after the Solar System coalesced. This theory depicts the Earth colliding with a 'proto-planet' leading to the creation of the moon. The simulation is an older model (circa 2007) where Earth collides with a smaller planet. The idea seems comical at first: What if we're all characters in a giant computer simulation controlled by superior beings? But a lot of scientists aren't laughing at the notion. In fact, some think there's a decent chance we truly are living in some sort of virtual reality.

The Giant Impact Theory (or Big Splash or Big Whack; cf. Big Bang) is the leading scientific theory for the formation of the Moon, which is theorized to have formed as a result of a collision between the young Earth and a hypothetical Mars-sized body sometimes called Theia.The theory was first proposed in a paper published in Icarus in 1975 by Dr. William K. Hartmann and Dr. Donald R. Davis. Giant Impact Hypothesis. The impact around 4.5 billion years ago is described in the Giant Impact Hypothesis, which is the current prevailing theory on how the Moon was formed and how Earth got its tilt. Ever since this impact, Earth has been orbiting the Sun at a slant. This slant is the axial tilt, also called obliquity.
