So I was in the shower today...

[Agamemnus]

However, this isn't the end of the story. The force applied upon the center of the earth is equal to the sum of the force exerted upon the earth by the entire mass still affected by gravity. You can argue that the ground isn't affected by gravity, and I can then empirically prove you wrong by throwing dirt at you.

Not sure what you mean by "still affected by gravity", but I never disagreed with that.

The sum of all the force applied by all the different layers of the earth, with all their different gravitational constants, is then multiplied by the area of the core.

Not sure what you mean by gravitational constants. I assume you mean the surface area of the outside of an arbitrary "core".

With that completed, you'll immediately see that there are massive pressures at the center of the earth. Those pressures increase the melting temperature of any substances unlucky enough to be that far down, resulting in a solid core surrounded by superheated magma.

You need to divide all the gravitational forces by the surface area not multiply by the area to get pressure on the sphere's surface area, per square unit of distance. You also need to account for other forces as I said before that can counteract the pressure exerted by the force of gravity.

And if you don't understand, I recommend taking a physics class or at least reading a book. Glenn isn't the only person around here with university-level physics under his belt, and watching your weekend warrior attempts against people who are also applied or theoretical physicists is painful.

Another one trying to turn this into a credential contest. That's what, 3 now? Don't make me laugh.
