According to the Scientific bulletin of the Massachusetts institute of technology (MIT), Rob de Meijer from the University of Western Cape in the Republic of South Africa and Wim van Westrenen from the Amsterdam Vtije University have elaborated a new hypothesis about an origin of the Moon. According to it, the Moon was created in the result of nuclear reaction inside our planet which resulted in (bringed to) detonating and ejection (burst) of a gigantic mass of its material (substances) into the cosmos.
In contrast to the more widespread hypothesis of formation of the Moon at the expense of impact of an asteroid with Earth, and knocking-out (splitting-out) a huge fragment from our planet, which does not offer an explanation to an equal ratio of isotopes in earth and lunar basalts (under this theory, only 20 % of lunar material should have earthly origin, and remaining 80 % - an asteroid material), Meyer and Vestrenen's hypothesis gives good explaination, why lunar and earth rocks are so close to each other by isotope composition.
On their version, in the process of formation of Earth from a protoplanetary cloud, heavy radioelements, such as uranium and thorium, concentrated on (along) equator. In the moment, when their mass had exceeded an extreme mark, chain nuclear reaction had started, and under the Earth surface a georeactor had been formed. As a result of nuclear detonation, matter had been thrown out (erupted) from the the bowels of Earth into the cosmos, and in due course had been taken a shape of the satellite.
My commentings: Appearence of the hypothesis of Meyer and Vestrenen - an important contribution in determination of the nature and origin of the Earth's satellite. It explains such important peculiarities (features) of structure, composition and character of movement of the Moon which any former theory could't explain. However, the given hypothesis has its imperfection too. So, it assumes that separation of the Moon from Earth took place some billions years ago. However, it contradicts to examinations of scientists from the Planetary Science Institute (NASA, USA) and the Brown University (USA) under the leadership of professor Peter H. Schults, according to whom volcanic mounts around Ina area were created only 1-10 million years ago. Professor Schultz and his collaborators assure that four more similar zones have been discovered on a lunar surface at least.
Found out by both the Soviet and American automatic stantions and astronauts rocks, having age 4-4,5 billion years, on the Moon, similar in composition to earth basalts, equal isotope composition of lunar and earth rocks, thickness of lunar crust (60-100 km), comparable to thickness of ancient continental platforms on the Earth, and presence on the Moon young, 1-10 million years age, volcanic structures, indicate that a huge fragment of an ancient continental platform which then became the Moon, had been torn off from Earth quite recently (accordind to geologic data).
Separation of the Moon from Earth is depicted (described) in details in ancient legends - the Indian legend about churning of the ocean around Meru world mount (the North pole) by gods (Adityas) and demons (Daityas, Danavas, dragon-people of Nagas, and multiarm beings of Rakshasas) led by Vishnu, the Aztec legend about run-upping (spin-upping) of vault of heaven round the world mount Koualkan (the axis of Earth), as a drill, by Kamashtli - Mishkoatl, Tlalok, Shipe or Teskatlipoka and the legend of Hopi indians about assignment by the order of Sotuknang - the assistant of Sovereign Creator Tayowa, an axis of the Second world to itself (+ the Japenese legend about run-upping (spin-upping) of vault of heaven round the world mount Onogoro). According to comparison of folklore and geologic data, carried out by me in the book "Battles of ancient gods" and a number of my more late works, the main of which is "The most important catastrophe in the history of Earth during which mankind appeared. When it happened?", this event had place, most likely, at the boundary of the Early and Middle Miocene (16 million years ago) and had led to one of the most destructive catastrophe in the history of the Earth.
Appearence of the Moon in the sky and properly episode of its tearing-off from Earth is described in legends practically all people living on the Earth - from Tierra del Fuego to Alaska and from Peru to Australia. It had led to crack (split) of lithospheric plates, to formation of an ocean wave more than 4-5 km in altitude, washing away from the Earth's surface all its former inhabitants into submontane and intermountain troughs (sags) and rift troughs (further they were transformed there, in reducing conditions, to oils and gas deposits) and, most important, to the abrupt (dramatic) change of an inclination of Earth's axis. If earlier, according to Mexican, Egyptian, Chinese and Australian legends, the sun rised in the North, so after the catastrophe it began to rise in the East though at first it appeared in different places (as well as the moon, which was then as big as sun or rather bigger).
It follows from all told above that the nuclear explosion at the expense of which the Moon had been torn off from Earth, most likely, was man-made (artificial), having induced consciously by former reasonable inhabitants of our planet, and the Moon has much younger age, than the majority of explorers considers.
What the Moon was necessary for? Read about this and many other things, related to separation of the Moon from the Earth, in more details in my book "Battles of ancient gods", and also in the works "Separation of the Moon from Earth at the Early and Middle Miocene boundary" and "Moon - a fragment of Hyperborea!?"
