There is not a single scrap of evidence that navigable, stable, macroscopic wormholes exist in the real world. There doesn't seem to be a plausible, theoretical, way for nature to actually form them from the kinds of processes that are so common today. If they come from supernova and ordinary black holes, then from our perspective, the corps of the imploded stellar core will always be in the way of our ever using them, and gravitational radiation will cause the wormhole spacetime to be very unstable.
