I know virtually nothing about architecture or structural engineering, but I imagine all the weight isn’t necessarily going down from floor to floor, but a lot of the weight is attached to support columns, and the floors are built out from that.
All the weight is still on those support columns though, and I also have a hard time wrapping my head around how something like that is possible. Engineering is amazing.
I think what they meant was not literally the bottom floor, but the columns at the bottom floor.
