Do we actually know what the earth's core is made out of?

Like are there any technology we can use to see earth's core? Isn’t the biggest hole we drilled only like 0.2% the amount that is actually there? How do we know the earth isn’t hallow (even though I don’t believe the hollow earth theory one bit), how do we know, if there is not certain techniques we can use to view the center of earth?

Humans have often wondered about what lies at the center of our planet and have considered hidden civilizations, hell, dinosaurs and interior oceans among the possible candidates.
Within the past 100 years, great strides have been made in the study of the earth's core, and much to the disappointment of sci-fi fans, it appears that it is nothing more than an outer shell of liquid iron surrounding an interior of solid iron (mixed with sundry other elements).

Chocolate?

























Seriously though, I always thought middle earth was where there was lollipops and sunshine?


I think its magma or the like. Flowing, rotating, doing stuff no one knows about that makes all this work.

Or its the underpants gnomes home.

According to most "scientists", the core is made up of the following:

approximately 85% Fe, 5% Ni and ≤10% of minor lighter components (in weight %, or about 77% Fe, 4% Ni and 19% other in atomic proportions).

It is my opinion that it might be a highly magnetic metallic crystalline composite. But, we really don't know for sure.

It's iron and uranium, among other things.

See J.M. Herndon's Georeactor for details.

Now you know. It's been disclosed. Don't freak out.

Wait..so the georeactor is the sub core? What is the sub core made out of iron still right? Thanks for the link

What? You didn't know? It's where all of the humans raw sewage and garbage goes.

No just joking I think it is what scientists say but hey they could be lying to us

I know for a while there were theories that there was an inner-inner core of uranium, maybe about a mile in diameter, but I read just a few months ago that that theory has been generally dismissed with some recent studies.

The idea was that the uranium core is what has helped keep the core heated and the Earth's magnetic field churning, but now it seems it's must just still hot iron from when the Earth formed (with a goodly amount of uranium mixed in).

Link please.

We would like to read more. Fascinating...

I just read something yesterday in scientific american that they are going to use neutrinos to see right through planets, stars and see what is inside them like an xray.
