Maybe I am silly.
Is it not an Idea to build a pyramid like structure that is 100x larger than the pyramid of giza. It would be facilitating many research ground/labs under various base pressures, temperatures and air composition for example, but also could have a launch port at the top towards space, making it usefull for exploration and mining. At the bottom areas it'd also be facilitating general living spaces as if it was a vertical city.

Why?
