The 6 Silos Expedition

 The question is: what to do with the dirt? 

The expedition--digging the deepest hole in the earth--is sure to generate a lot of it. But it's a finite amount. A little math will tell us exactly how much. We know the crust is approximately 40km deep. If we want to dig a hole that's 10 meters wide, then we'll get 3,141,592.65 cubic meters. That's just one and a half Sears Towers worth of dirt. 

It seems to me that the best route forward would be to build 6 silos near the job site, each a quarter of the height of the Sears Tower. 6 silos about 36 storeys tall would hold the dirt that is generated by digging the deepest hole in the world. 

Beyond the crust, there is no dirt. There is just fire, molten fire. We'll figure out what to do with that when we get there 

There is a certain romance to this idea. You'd see the silos for dozens of miles before you get to the job site. The silos would tower over the area, lending a certain majesty to the whole endeavor. The entire expedition would become known for these silos. A journey inward defined by 6 spires that soar outward. 

We need this journey. We need an expedition to the center of the earth. We need to know more about what lies beneath us, what forms this terra firma. We need to lay our eyes on it, to stick our hands into it, to consummate our relationship with this planet by truly getting to know it for the first time. Because doing so will literally bring humanity closer together. 

The first step is figuring out what to do with the dirt. 

Done.
