The good news: science shows that wormholes can exist; the bad news, however, they are unusable to travel through interstellar space. Apparently travel through a wormhole would be much slower, then travel outside it.
This is a real dumper on those who hoped to cross the galaxy in relatively short time – as wormholes used to be the most promising method of effective “faster-than-light” travel… But perhaps we should not give up as science might still find another way to use wormholes as a potential interstellar road network.
Physicists at the University of Barcelona has created a magnetic wormhole. This device can transport a magnetic field from A to B without being detectable in the intermediate space. In science fiction wormholes are a popular method of interstellar travel as it allows apparent faster-than-light travel. However, the magnetic wormhole does not allow material objects to be transported but one never knows where this development will end.

Mundane science fiction, the preferred genre on this site, builds stories upon the solid rock of known science rather than on made-up science. Consequently MSF features almost exclusively stories set in our own Solar System, since with the current state of science interstellar travel will take centuries if not longer, because faster-than-light (FTL) travel is almost impossible under accepted theory of physics.
