Mystery of the Moon.

<P> Divergent origins of Moon: </ P> <P> the origin of the moon, roughly three factions, but not yet conclusive. .Some scientists believe that the moon is 46 billion years ago, the universe and the Earth as the formation of gas and dust; others believe that the moon is the Earth's children, split from the Earth. .However, the sun and spirits back to the data several times, the Moon and the Earth's composition quite different. .Many scientists believe that the moon many years ago, accidentally inhaled gravity range, which was accidentally included in the Earth's orbit. .However, some people refer to celestial mechanics to oppose this statement. .</ P> <P> ancient Earth than the moon: </ P> <P> scientists were surprised that the rocks brought back from the moon, 99% vs 90% of the ancient Earth rocks but also old. .Astronauts brought back lunar rocks, has been determined that 43 million years to 46 million years of history, which has the equivalent of the solar system's history. .</ P> <P> soil more distant than the rock: </ P> <P> the first time American astronauts landing "Ningjing Hai", the soil than we age old rock. .According to the analysis, a difference of 1 billion years. .By chemical analysis showed that the soil on the moon is not the evolution of the rock, likely to come from somewhere else. .</ P> <P> by the impact will be tremendous noise: </ P> <P> number in Apollo lunar exploration, the moon landing craft and rocket return, he will hit the lunar surface. .But every time the moon like a big brass gong or bell sounded the same, when the Apollo 12 moon, the moon's echo also lasted four hours, there is no scientist can explain this phenomenon. .</ P> <P> shadow area are rare: </ P> <P> in the earth, the moon, will see some shadows, landing astronauts to the original level of the shadow area, find it .difficult to drill holes on its surface, the study of soil samples where the presence of metals such as titanium, Pei, Y, etc., this was very surprised scientists, because these metals to very high heat - 6000 degrees Celsius .above is possible to melt and mix with the surrounding rock in some. .</ P> <P> iron particles will not rust: </ P> <P> astronauts brought back from the moon rock samples, contain pure iron particles, scientists believe that these iron particles do not .from meteorites. .Some experts report that these iron particles back to Earth, none of Health for many years had rust, iron rust in the scientific community or the first-ever encounter this kind of thing. .</ P> <P> smooth surface like a mirror: </ P> <P> many parts of the lunar surface smooth as a mirror. .What if I do not know the source of heat to be "hot" over the same. .Experts analyzed that is not here, by a huge meteorite impacts caused, and some scientists believe, the sun burst out of the heat is the main factor. .</ P> <P> magnetic shocking: </ P> <P> early lunar research, said that the moon has no magnetic field, in recent years, the analysis of moon rocks, before we know it has a strong magnetism. .However, the Moon rocks are really magnetic field, there should be a core of iron should be but the information now told us that such a large core can not exist in the heat inside the moon, it is impossible to obtain from the Earth's magnetic field ., as obtained from the Earth to the Moon Magnetic to be very close to the earth, so, it probably will be destroyed to get effort. .</ P> <P> concentrates the bottom shell: </ P> <P> space exploration brought back information, the shell under a large moon concentrates but also an attractive when the spacecraft could not help flying .to tilt. .Scientists only know that these concentrates is a heavy and dense material, the rest know nothing about it. .</ P> </ p>.
