Folks , moreover - a STUPID ball of iron , locked into place within a SOLID planet , simply can NOT wobble because it has NO ROOM to wobble ! This here again disproves the mainstream theory of solid planets...!
On the other hand , an inner Sun at the core of a hollow planet , which is powered by SELF-SUSTAINED nuclear reactions , can possibly wobble , because it has the room to do so , it can also cause Earth's magnetic field to fluctuate and even reverse from time to time .
**Incidentally , such fluctuations and "wobbling" of magnetic fields are characteristic of the manmade Tokamak reactors too !
I am being reminded here of the S.E.C.T. (Special Earth Core Theory) we've discussed before on this forum...hmm !
