Certainly?  Others used to say that the Earth is certainly not off-center as 

far as the universe goes, but those doing the math could prove otherwise.



It's fascinating, I tell ya.  And credible.  A breeder made by God.  

Supporting life on Earth as we know it...

helium, and the geomagnetic field", Proceedings of the National Academy of 

Sciences USA, Vol. 98, no. 20, p. 11085, September 25, 2001.

Abstract:Geomagnetic field reversals and changes in intensity are

understandable from an energy standpoint as natural consequences of

intermittent and/or variable nuclear fission chain reactions

deep within the Earth. Moreover, deep-Earth production of helium, having

3He/4He ratios within the range observed from deep-mantle sources, is

demonstrated to be a consequence of nuclear fission. Numerical simulations 

of a planetary-scale geo-reactor were made by using the SCALE sequence of 

codes. The results clearly demonstrate that such a geo-reactor (i) would 

function as a fast-neutron fuel breeder reactor; (ii) could, under 

appropriate conditions, operate over the entire period of geologic time; and 

(iii) would function in such a manner as to yield variable and/or 

intermittent output power."
