Space elevators. Ring worlds. Dyson spheres. And much more beyond. The human race has always dreamed big. But how far can technology go? How big can our machines and artifacts get? In MEGASTRUCTURES: SCIENCE AND SPECULATION, we examine future technology concepts of the immensely big, as imagined by scientists, engineers, writers, and artists alike. From supertall skyscrapers to space colonies to machines that can move entire stars, each idea is fully explained and examined in fascinating detail. Join us as humanity's ingenuity challenges the very scale of the universe itself!
