And can we use them to traverse the universe?
In science fiction, space explorers routinely zip through wormholes in space-time that are connected by two black holes — celestial objects so dense that not even light can escape their clutches.
Some physicists predict that a wormhole could become more stable if it was formed from a spinning black hole, but our understanding of what happens in that scenario is murky at best. But that same mathematics also allows for the exact reverse of a black hole: a white hole. A white hole still has a singularity at its center and an event horizon surrounding it. But instead of falling in and finding it impossible to escape, with a white hole a person could never reach the event horizon from the outside, because it's constantly flinging its contents out into the universe faster than the speed of light.
The other problem with Einstein-Rosen bridges is their stability."This bridge is a kind of wormhole, but it is transient: it pinches off before any object can use it to pass from one side to the other. So in this sense one does not really have a wormhole, since one cannot traverse it," Samir Mathur, a physicist at The Ohio State University, told Live Science in an email.
The combination of the uncertainty of the existence of white holes, the instability of Einstein-Rosen bridges, and the relative non-utility of them means that if wormholes exist, they probably aren't Einstein-Rosen bridges.
