with a mass of about 108 kilograms, the amount of iron in a sphere about 30 meters in diameter.

WTF ? a 30 meter BALL of melted iron is gonna weigh MUCH MORE.

I caught the same thing. Heck, I stand under two meters high, and I weighed in at ~96kg this morning. I still float in water, so I think it's safe to assume I'm less dense than molten iron.

Methinks the author missed a few zeros.

"...a 30 meter BALL of melted iron is gonna weigh MUCH MORE."

Yes. Stevenson’s "modest proposal" is probably some kind of left/liberal satire. Iron at any weight would not even be a candidate for any kind of deep earth shot. A very hard rock would be better.

The most likely object to go to the center of the earth would be a very large meteor traveling toward it from way out in space at a very high rate of speed.

And we know what other kinds of effects that would be likely to have.
