I am sorry that you believe the magnetic field proves the eart5h to be solid. I do not believe this is proof whenb weighed against all of the proof I have that it is hollow. Rather I am sure that the magnetic field is not clearly understood.
As for the positrion of the earths orbit and it's mass: the theory is based on a mass that is of a solid earth and then circular reasoning. I am sure that if you concidered all planets as hollow then you would see that the balance would be the same. As for the weight or mass of the sun, it is calculated with the same circular reasoning and therefore proves nothing.
I stand firm in my belief that the earth is hollow because I understand how it became this way and it explains far to many events shown in scripture. Namely: the bottomless pit, the beast Abaddon, the locust, the ice age, the flood as the bowels of the deep bust open as from a mothers womb, the water above and below, as well as the reason God has to slap the earth with an asteroid. Not to mention the stories of some finding it and entering into it while others can't find it. There are far to many absolutes to deny a hollow earth because of a couple theories, sorry.
