No. It supports a liquid metal outer core that has eddies which result in the magetosphere. If it were hollow, that would be readily apparent from seismic surveys. In addition, the gravity, which is measureable confirms our conclusion about the structure of the earth.

The hollow-earth and magnetism theory first came out about 400 yrs ago. And was soon debunked when geologist learned to use seismic data (just before WW1 time).

There is no new frontier there. Sorry.

But the absence of a hollow center does not rule out the possibility of life there.....read "The Fires Within" by Arthur C Clarke (written in 1947). A fun short story on the subject.

Think of the earth as a baseball that a pitcher has thrown so that it has a slow spin. The north & south pole are just imaginary points about which the ball spins.

The earth is not at all hollow, but has a solid core of mostly iron.
Because the earth has so much iron its like a bar magnet. The magnetic poles are almost but not the same as that imaginary pole about which our "ball" is spinning.

Like a thrown baseball, nothing is supporting the earth. It is traveling thru space. However because of the imense gravity of the very huge sun, the earth is pulled toward the sun at the same time it is trying to fly off into space. This is like someone holding one of your hands while you're trying to run off. They dig their heels in and you just keep running around them. That's the earth running around the sun.

NO. magnetic poles support a solid earth theory. If the earth was hollow then what is creating the magnetism? Think about it.

How did you ever come to the conclusion the Earth was hollow? I hope not from a teacher.
