Science Fiction Stories with Good Astronomy and Physics: A Topical Index
Basically anything by Greg Egan is great.<p>His early short stories have a lot of "drugs can let your brain talk to other dimensions" and "your mind literally makes reality" (though some of those are also really good, "The Infinite Assassin" is a great read and it's only like 15 pages), but his later full books are basically all hard (if speculative) physics stuff.<p>Dichronauts is difficult to get your head around, but very rewarding. It's about cartographers who work in a universe with essentially 2.5 dimensions of space and 1.5 dimensions of time.<p>The Orthogonal trilogy is about a species living in a toroidal universe where all 4 dimensions are identical and interchangeable.<p>The universes of Diaspora, Schild's Ladder, and Incandescence are set in a future when most intelligent life in the galaxy lives in a network of space-computers and interact with the outside world via robots and programmable matter.<p>Oh and I almost forgot the Bobiverse series. Not by Egan, but still good. Some guy gets stuck in a brain-computer and sent off in a self-replicating space probe to prepare other planets for human colonization.
