> Dr. Josh Keyes: The core is the size of Mars. You're talking about jump-starting a planet. This is a superheated hyper-fluid of molten iron and nickel at 9,000 degrees Fahrenheit. And the deepest we've ever been is... 7 miles, with a two-inch drill bit. Space is easy. It's empty. We're talking about millions of pounds of pressure per square inch. Even if we somehow came up with a brilliant plan to fix the core, we just can't get there.
To put things into perspective, the deepest hole drilled, the The Kola Superdeep Borehole, is only 7.6 miles deep. Our deepest hold did not get anywhere near close to the core.
We know there is a core thousands of miles beneath our very feet, and we can only guess as to what exactly it is, a mystery beneath us our entire lives.
Look man, we may have taken the multicellular title from the frick'n worms [0], to say nothing of utterly trouncing our mole-brethren, so as far as I'm concerned we are winning. :p
Bruce Willis' AI likeness. Or however we are going to start referring to AI manifestations of dead actors. AI-zombie? AI-reincarnation? AI-ghost-of-so-and-so?
> The core is about 4,000 miles from the Earth's surface and, despite best efforts, scientists have so far been unable to reach it.
