What would happen if you covered the entire earth with a mile thick layer of say rock or steel (possibly material collected from the asteroid belt or other moons/planets) then built a giant, structure on the north pole area. this structure would be large enough to easily see from space. Large like 1/3 the height of the earth added on top. A giant mountain more than a building.
Anyone want to wager a guess what if anything would happen regaurding gravity, orbit, rotation or anything else.
