I was expecting to see Arthur C. Clarke's "Fountains of Paradise" (where I first heard about space elevators), but it looks like this isn't aimed at technological ideas, more straight science. Though "telescopes" is one of the categories. Glad to see Poul Anderson's "Tau Zero" on the list - that made a big impression on me when I read it back in the 70s. Fun that Ted Chiang's "Exhalation" shows up in 3 different categories. Stunning story. I would have included his "Tower of Babylon" story as well - in cosmology <g>.
