Maybe this is a stupid question but: The Earth attracts every single body in it's gravity range to the center of the it, right or wrong? If this is true then is the asolute center of the Earth 0'G ? I am saying the absolute center of the planet, the absolute center of the core. Will it be 0'G ?

Every particle of matter in the Earth is attracted to every other particle,
which means once you get to the centre of the Earth you're going to be getting pulled equally from every direction. Which means you will always still be attracted to the centre.

If you hollowed out a tiny chamber at the exact centre of the Earth, it perhaps would simulate 0G, as the gravitational forces should all cancel each other out.

So in the center of the Earth gravity pulls you everywere so then it cancels itself out, right?

Isn't this what happens in orbit around the Earth?

That'd be my guess.

If you're on the surface of the Earth you're only going to be getting pulled significantly in one direction, from below your feet.
