    Default Our Anomalous Moon

    It is a sixth the size of Earth. In relative comparison to Earth and other planets with moons this is quite large Most moons in the Solar System orbit the gas giants and the biggest ones are a similar size to our moon.

    The Moon is less dense than Earth. Some people have considered it to hollow inside and maybe even something built by aliens.

    Interesting articles, Bill, thank you. They make me want to do some research of my own to compare - not by going there, I hasten to add, but certainly looking for facts among the theories.

    The most likely theory for the Moon is that it was formed in the early stages of the solar system by a Mars-sized object colliding with the nascent Earth. This blew off a big chunk of the outer part of the Earth, but not the iron core. Moon rocks that have been brought back bear striking similarities to rocks on Earth in terms of composition (though not structure), suggesting this theory is the most likely one. Because it was only the outer part and not the heavier iron core, the Moon lacks that iron core so is less dense.

    You started off so well...

    The sicence fiction writer and professional scientist - Isaac Asimov also thought that there was something funny about the Moon.

    e.g. Regarding Lunar eclipes he said: There is no astronomical reason why the moon and the sun should fit so well. It is the sheerest of coincidences, and only the Earth among all the planets is blessed in this fashion." -- Isaac Asimov.

    He also said that: "We cannot help but come to the conclusion that the Moon by rights ought not to be there. The fact that it is, is one of the strokes of luck almost too good to accept… Small planets, such as Earth, with weak gravitational fields, might well lack satellites… … In general then, when a planet does have satellites, those satellites are much smaller than the planet itself. Therefore, even if the Earth has a satellite, there would be every reason to suspect… that at best it would be a tiny world, perhaps 30 miles in diameter. But that is not so. Earth not only has a satellite, but it is a giant satellite, 2160 miles in diameter. How is it then, that tiny Earth has one? Amazing."


    Irwin Shapiro,
    Harvard-Smithsonian Center for Astrophysics

    “The best possible explanation for the Moon is observational error – the Moon doesn’t exist.’

    "The Moon is bigger than it should be, apparently older than it should be and much lighter in mass than it should be. It occupies an unlikely orbit and is so extraordinary that all existing explanations for its presence are fraught with difficulties are none of them could be considered remotely watertight."

    There is a coincidence that the Moon and Sun appear almost identical in size from Earth, so that total eclipses are an awesome sight. If we'd been around at the time of the dinosaurs, eclipses wouldn't be as spectacular as they are now, because the Moon would block out an area bigger than the apparent Sun, so you wouldn't get that amazing "diamond ring" during an eclipse. If we didn't evolve into humans for another few million years, then the Moon would be further away, and an eclipse would always be annular and simply make the Sun into a disc without blocking out all its light.

    However, just because Asimov pointed out that we live in a sort of Goldilocks moment regarding eclipses doesn't mean he thought the Moon was hollow and made by aliens. Also, he was writing a few decades ago, before we discovered that virtually all stars have planets - back then, we thought that planets were probably quite rare.

    He wrote a great book called "The Tragedy of the Moon", which I read as a kid. His argument was that the Moon was responsible for our sticking to geocentric theory. The ancients could have explained the apparent movement of the Sun in two ways: the Sun moves round the Earth, or vice versa. However, the heliocentric theory was buggered up by the fact that it can't explain the motion of the Moon. So, either everything moves around the Sun except for the Moon, which moves around the Earth (true), or everything moves round the Earth (false, but simpler). Because that theory was simpler, it stuck, and delayed science by hundreds of years.

    His next chapter was "The Triumph of the Moon", which pointed out that despite this, without the Moon we wouldn't have tides, and therefore probably wouldn't have evolved into humans in the first place to be able to ask such questions.
