Bigger Than Worlds, Larry Niven
Part of my English syllabus involved making presentations to the class. One of mine was based on this article and explored the sort of structures we might someday build in space. What impressed me at the time was the scale of things. It starts by blowing up asteroids like some sort of giant balloon and fitting an inhabitable ecosystem on the inside. Later on there is talk of "dismantling" gas giants to provide building material for Ringworlds or Dyson Spheres. After that it starts to get really outrageous.Bigger Than Worlds
