[Servant of the 9]

Marking this for support on my theory that the core of the Earth is a neutron star, which went supernova and collapsed to the size mentioned, attracting debris to it and forming the layers around the core up to the mantle and surface of the Earth. It is the 'engine' that generates the heat, keeping the magma hot, and generates the magnetic and electrical fields via interaction with solar energy passing past the Earth from the sun.

A neutron star has a magnetic field of billions of Gs.
One in the core of the earth would absorb the entire planet in short order.

There was a fictional book back before 1990 or 91 that talked about a singularity inside the earth. It also spoke about the Internet before it was even really on the scene and the part it plays on getting the word out.

Believe it or not I think it was called "Earth" or "Gaia" or some derivation of that one of two. A google search turned up a book by David Brin who seems to be conservative. Interesting (in a fun way) type of read. But pretty much as you talk about.
