According to the Russian Tv Today website reported on November 16, a new study shows that objects, including spacecraft, can use multiple black holes as a "shortcut" to quickly travel through the universe.
The new theory, proposed by French physicist Pascal Koylan, marks a break with early research in the black hole research community. Previously, it was thought that the so-called "wormhole" composed of two black holes could easily collapse in an instant, resulting in objects unable to enter from one side and successfully penetrate from the other side.
By using different metrology scales, however, the French scientist's new model arrives at a very different conclusion: an object — such as a spacecraft — can pass through such a wormhole portal intact to reach a distant region of the universe, using far less time than would be required to travel in a conventional way.
The full paper on the study will be published in an forthcoming issue of the Journal of Modern Physics Volume D, although an abstract has been published since early October.
However, there is still too much uncertainty about whether this purely theoretical model has anything to do with how the universe actually works.
First, to create such a space-time tunnel, you need a regular black hole and a so-called white hole, which is actually a reverse black hole. Black holes never release any energy and matter outward, and their "twins" white holes never absorb anything. Thus, according to Einstein's theory of general relativity and Nathan Rosen's addition to it, if you connect the two, they form a bridge across space-time. But if the laws of another branch of physics— thermodynamics— are obeyed, such a structure would be extremely unstable. Perhaps more importantly, the existence of a white hole has not yet been proven beyond reasonable doubt. At present, they are still purely theoretical assumptions, and it seems rather unreliable to talk about space-time portals.
