* The ''[[Humanx Commonwealth|Flinx and Pip]]'' novel ''The End of the Matter'' features a white hole used not for transportation but to destroy (slowly) a black hole of equal but opposite mass. This is of course [[Unrealistic Black Hole|nearly as unrealistic]] as the trope being discussed.
* In ''Sphere'', the {{spoiler|future ship}} used a black hole that ''creates'' a wormhole, using a [http://en.[wikipedia.org/wiki/Kerr_metric:Kerr metric|Kerr metric]]; the black hole spins so rapidly that it warps nearby spacetime so that two distant locations and times touch.
* While the word "wormhole" is never used in ''Angel Station'' by [[Walter Jon Williams]], all ships use captured black holes in order to perform FTL jumps. This requires precise calculations, which are done perfectly by one of the protagonists, because she's a "witch", a genetically-engineered girl with the ability to see and alter electron motion. Opening a "tunnel" creates in a massive radiation wave that can damage anything for thousands of miles, meaning jumps have to be made far away from planets or other ships. It is also revealed that {{spoiler|aliens use the same method}}. Apparently, any ship can be equipped with devices for capturing black holes. Why they don't get torn to shreds by gravity is never brought up.

* ''[[A Wrinkle in Time]]'' has Tesseracts, which basically function as wormholes. [http[wikipedia://en.wikipedia.org/wiki/Tesseract |Real Tesseracts]] have nothing to do with this, being a geometric concept related to cubes (basically, a Tesseract is to a cube what a cube is to a square). Wormholes were not topical at the time.
* ''[[Quantum Gravity]]'': There are portals between realms used to get from one to the other. Or into I-space.
* The [[Honor Harrington (Literature)|Honorverse]] has several wormholes but rather than a tunnel in space they are described as points where extremely powerful standing grav-waves that normally exist in hyperspace overlap with real space and allow effectively instantaneous travel between their two ends. They all come in clusters of at least two and a large portion of Manticore's wealth comes from shipping fees of their own six, later seven, terminus wormhole junction, the largest in the known galaxy.

* Because black holes don't mesh very neatly with quantum mechanics some physicists have put forward the idea of a [http://en.[wikipedia.org/wiki/Black_Star_%28semiclassical_gravity%29:Black Star chr(28)semiclassical gravitychr(29)|"black star"]] which is like a black hole, but not.
