Earth Should Be Hollow

So the Dyson sphere has neutral stability everywhere.

And which incidentally is a different statement than the incorrect assertion made above that the gravitational field vanishes inside a spherical shell in which there is an additional point mass. Things will still orbit the point mass (e.g. star) inside the spherical shell, just as if the shell wasn't there at all, which is a way of stating that there is still a non-vanishing gravitational field in there.

Fair enough -- the field (potential gradient) due to the shell is zero; that due to a star or other objects inside the shell is not.
 
Is this skycentrism? The folks at Phil Plait's old site www.bautforum.com already debunked this one...

No this has nothing to do with skycentrism, for starters I never once said we lived inside the Earth or that we could even reach this hollow area cos of the depths we'd be talking about not to mention the lack of oxygen down there and the fact we'd have to get through a molten lava layer to get there.
