Thoughts on strange ideas

This is a response to a conversation I had about the possibility of the moon being a hollow sphere, containing who knows what.....

I consider the hollow moon in the same way that I consider the old hollow Earth theories. Doesn’t seem particularly credible, especially when considered with the results of geological surveys of the moons surface showing reasonably unequivocally that it was formed by a large scale planetary collision in the early days of the solar system blasting debris into orbit around the still forming Earth. I guess you could make a case for the possibility. You could consider the use of a toroidal plasma engine as a power source similar to that suggested for the TR3B black project anti-grav aircraft, but on a much larger scale, possibly with the outer surface being taken from the early Earth by a hyper-advanced alien civilization. The use of this type of engine would allow both for the enormous energy requirement, and the gravitational discrepancies between a solid body and a hollow sphere.

Of course, potentially anything is possible for a sufficiently advanced civilization. Michio Kaku and others have suggested that there are levels of civilization based on energy usage, with a level one civilization using all the power output of a star, through to a level three civilization using the power output of entire galaxies, and if you consider that the universe is some 15 billion years old and our particular bit of it is more like 6 billion, the possibility of a civilization a billion or so years in advance of ours is not beyond the bounds of credibility, but there is a substantial caveat in my opinion….

….Why? What purpose would a hollow moon serve? It would have to have been created, but to what end? It seems an enormous amount of effort fr some sort of observation post. I guess it could be part of an overarching plan to stabilize the early earth to make it more habitable but wouldn’t just moving a planetessimal into position be easier? It doesn’t seem to make sense, unless of course it is an interplanetary escape module left there for when we become so technologically advanced we can recognize it for what it is, and coincidentally have so completely stuffed up our own planet that we need it? That would be quite cool, but personally I think it is unlikely.

Of course, since we haven’t yet managed to full comprehend life and all of its possibilities perhaps hollow moons are some tremendously ancient life form that we simply can’t comprehend, but I fear that we are slipping into Pratchetts World Turtle realms here…..speaking of which, I liked the answer given by Didactylos in Pratchetts “Small Gods” when asked to refute the World Turtle story, “I will write another paper to refute it, a universe of spinning balls, I shall give you more balls than you can imagine…”
