The Haunting of Hawking
Not as much of a story, but the concept, physics, and engineering in Larry Niven’s Bigger than Worlds brings out ideas that most of us have only thought about for a few seconds, if at all. A synopsis of how a man-made structure could exist in a way to accompany humanity, the essay has a big imagination and an even bigger hope for the future. I could not find a good link to an html version, but there were a few sites that you can download the pdf. Check it out!
