Moon Rock Idiocy
Sweet Jesus, how pathetic is this reporting?
Researchers have found evidence of the world that crashed into the Earth billions of years ago to form the Moon. Analysis of lunar rock brought back by Apollo astronauts shows traces of the "planet" called Theia. The researchers claim that their discovery confirms the theory that the Moon was created by just such a cataclysmic collision. The study has been published in the journal Science.
The accepted theory since the 1980s is that the Moon arose as a result of a collision between the Earth and Theia 4.5bn years ago. Theia was named after a goddess in Greek mythology who was said to be the mother Selene the goddess of the Moon. It is thought to have disintegrated on impact with the resulting debris mingling with that from the Earth and coalescing into the Moon. It is the simplest explanation, and fits in well with computer simulations. The main drawback with the theory is that no one had found any evidence of Theia in lunar rock samples.
Earlier analyses had shown Moon rock to have originated entirely from the Earth whereas computer simulations had shown that the Moon ought to have been mostly derived from Theia.Go figure!!! Why on earth would moon rock look like earth rock? Hmmm....
Now a more refined analysis of Moon rock has found evidence of material thought to have an alien origin. According to the lead researcher, Dr Daniel Herwartz, from the University of Goettingen, no one has found definitive evidence for the collision theory, until now. "It was getting to the stage where some people were suggesting that the collision had not taken place," he told BBC News.What about the idea that the moon rocks were fake!?!?
"But we have now discovered small differences between the Earth and the Moon. This confirms the giant impact hypothesis." But the difference, some say, could be explained by material absorbed by the Earth after the Moon formed. And Prof Alex Halliday of Oxford University, is among many scientists who are surprised at the difference between the Theian material found in the Moon rock and the Earth is so small. "What you are looking for is a much bigger difference, because that is what the rest of the Solar System looks like based on meteorite measurements," he said.What a joke!
Dr Herwartz measured the difference in what is called the isotopic composition of the oxygen contained in rocks on Earth and Moon rock. This is the ratio of different forms of oxygen. Studies of meteorites from Mars and the outer solar system show that these ratios are markedly different -rather like a fingerprint. So Prof Halliday and others are puzzled by the fact that the fingerprints of Earth and Theia seem almost identical.So puzzling!!!
One possibility is that Theia was formed very close [sic] the Earth and so had a similar composition. If that was the case it raises the possibility that the assumption that each planet in the current Solar System has a markedly different fingerprint that needs to be revisited, according to Prof Halliday.
"It raises the question of how well the meteorites from Mars and the asteroid belt in the outer Solar System is representative of the inner Solar System? We do not have samples from Mercury or Venus. "They may well be similar to the Earth. If that is the case then all the arguments over the similarities of the Earth and the Moon fall away," he told BBC News. Dr Dr Mahesh Anand from The Open University described the research as "exciting" but noted that the data was from just three lunar rock samples.
"We have to be cautious about representativeness of these rocks of the entire Moon, and so further analysis of a variety of lunar rocks is required for further confirmation," he said. Other theories have been proposed to explain why the composition of the Earth and Moon are so similar: one is that the Earth spun much faster before impact, another is that Theia was much larger than current models suggest. An alternative, controversial, theory proposed by Prof Rob de Meijer of Groningen University in the Netherlands was that the Earth's crust and mantle was blown into space by an accumulation of nuclear material 2,900km (1,800 miles) below the surface. It was this debris that clumped together to form the Moon.Yes, either that, or the rocks are not from the moon but are fake moon rocks from the earth. And there's already evidence for this, that was in mainstream news a few years back.
