I am highly interested in how the moon originated. Theories suggest that the moon is a chunk of the earth, or rather, both were at one point one celestial body. Is there any literature out there with regard to this topic? I mean papers and simulation applets and algorithms.
I'd recommend taking a look at this review paper. The author is well known for doing SPH simulations of lunar formation models, so it should provide a good starting point.
On a side note, the most popular moon formation theory is probably the giant impact hypothesis which suggests that the moon formed after a large body collided with the proto-earth.
However, you should be aware that there are severe problems with this model as it cannot properly explain the moon composition and/or the the angular momentum in the earth-moon system.
This paper gives a rather critical (and technical) discussion of the giant impact model and might also provide an interesting read.
