Still, it brings up an interesting question. Is it what's in the hole, or the hole itself that's worth 60 trillion? and if the latter, what exactly do you do with a 60 trillion dollar hole? You can't exactly move it. You can't sell off part of it, because really...what good is part of a hole? And who really needs a hole anyway?

If you need to have a battle with a galactic emperor and want to be able to dramatically throw them down into it, a $60 hole could be quite a bargain.

You could spend $60 trillion to build the hole, then fill it with 60 trillian one dollar bills.

I've always wanted to know what it would be like to find a planet with a dead core, drill a hold clean through it and jump down. Eventually you'd pass through the center start slowing down, stop, start falling again, repeat, until you came to a complete stop in the center where you would just float there.

Wouldn't the gravitational forces in the center cause tremendous pressure and kill you? Or am I missing something about a dead core?

The usual version of this problem (in HS physics books and such) assumes a frictionless hole, so you'd just kept oscillating back and forth until something else intervened. With the same periodicity as an object in low orbit, in fact.

Very low orbit. Watch out for that tree.
Lyr knows perfectly well that I was not saying that having a dead core is impossible. (I considered editing earlier, but decided to see who'd pick on it first. )

Yeah, the fact that this is impossible to begin with.
Doesn't Mars have a dead core?
I saw when we get there, we set up base camp, and break out the drilling equipment.
*high five*
Lyrhawn here gets it! We've got ourselves a crew!
What are we going to do when we get to the core? Jump start it with a few high powered nuclear explosions? Are we going to take a Genesis Device to terraform the planet?

Well first we'll pass pieces of paper with juvenile messages about each other's moms down through the hole towards each other. After that who knows?

gotta comment, sorry but if it's a frictionless hole, and uniform density planet your accelaration due to gravity will be 1/(percentage left to center)^3 * (whatever gravity is) again an assumption is that the planet is perfectly round, your jumping you will pop back out on the otherside at exactly the height you jumped into the hole from. so if you are dropped into the hole 1 foot above the ground you will pop back out(upside down of course) 1 foot above the surface on the opposite side.
we need to appoint a crew on mars to study this phenomenon in more detail.
