Ohio State University astrophysicist Paul Sutter has published an interpretation of the method of organizing rapid travel through the universe using wormholes. A team of his colleagues developed a theoretical way to create this phenomenon in space and navigate a path through space-time. And Sutter recounted everything in understandable words - what if there is an enthusiast who will do this?
First, we need a pair of black holes, not ordinary ones, but electrically charged ones. Physicists are not sure if such exists, but this is an important condition. And the charges at the holes must be opposite so that they are attracted to each other, forming a primary bond. It is already possible to travel through such a system, but there are two problems. First, if the holes are too close, then there is little point in diving into one in order to emerge through the other a couple of light years away. Second, wormholes are highly unstable and prone to self-destruction.
In order for such a wormhole not to collapse, it is necessary to connect the black holes with two cosmic strings - hypothetical one-dimensional curvatures of space-time. True, they still have nowhere to get them, and it is not a fact that they exist in the Universe at all, but the theoretical foundation looks convincing.
