There is no "hollow earth".
You know how I know there is no hollow earth, is it because I went to the center of the world to prove it? Nay!
It is because of this simple idea.
m/v = density.
Mass divided by volume = density!

Our planet is of a known density, a known mass, a known weight, because of gravity.
If we had 1/1000ths the density that we really do, because let's say the Earth was hollow, then we'd have 1/1000ths the gravitational force.
That is of course if our science is correct and gravity is based on mass not upon displacement of space.
The hollow earth theory has soooo many flaws, it's rediculus...will the guy who thought of it please blow his balls off?
