MIT-Led Mission Reveals the Moon's Battered Crust Is Riddled With Cracks 39

SternisheFan sends this quote from the Boston Globe: "The moon's battered crust is riddled with deep fractures that may extend miles underground, according to the first findings from two NASA spacecraft orbiting Earth's nearest neighbor. The results of the mission, led by a Massachusetts Institute of Technology scientist, surprised researchers, who said it will provide new insight into the evolution of the early solar system, and even help inform the search for life on Mars. Announced Wednesday, the discoveries are also a reminder that the familiar moon still holds secrets four decades after NASA ended its manned missions there. 'We have known that the moon's crust and other planetary crusts have been bombarded by impacts, but none of us could have predicted just how cracked the lunar crust is,' said Maria Zuber, the MIT geoscientist who led the mission, called GRAIL." Here are the abstracts from the three studies published in Science.

    And if some believe the Moon was larger at some time earlier, it fits my theory that it was not due to a “giant impact" but instead moved into the tidal lock pattern, which caused internal heating of the moon, and some shinkage internally, but the crust was already cooled and stiff. When you have a relatively stiff outer core, but the internal core is cooked and can shrink, the outer core will want to settle inward, but due to its already stiff composition, it can't just settle in. It will crack. The real question is: What caused it to get close enough to the Earth to get trapped in orbit around the Earth? Was it some other event past Mars? Or was it tugged into place by Martians? Note that the Moon is really a small planet. Is Mercury and Venus earlier moons of Earth that were discarded due to inapplcable usage as the Earth was cooked via tidal lock? Is Earth really an assembled planet? It is the only one in this star system that has plentiful water at the proper distance from the star to support plentiful life. You may just be part of a herd to be harvested some day. You are the only bipedal Earth lifeforms that can be convinced to board a spaceship because you believe that is the proper survival stratgey when the volcanism of Earth starts to make survival on Earth questionable.. But if you are really part of a herd, and the spaceships come to rescue you, the odds are good that the aliens are not really here to help you survive. The odds are good that they are here to harvest the herd.

    The parent is of course, insane, but im afrade you're also inaccurate.

    Dec 21st 2012 is the end of the 13th baktun and the beginning of the 14th baktun. This is important to the Mayans as they believed that we live in the 4th itteration of the planet earth. The first 3 failed, for various reasons, the longest being the third, which lasted 13 baktuns. The coming of the 14th baktun is important to them because it means this world will now be the longest running. Previous worlds were not well suited to life, and humans didn't appear untill this particular version. It's a sign that this world is good, pure, and running well. Makes me laugh every time I read something about the end of the world, they couldn't be further from the truth.
