A wormhole or Einstein-Rosen bridge (by the two physicists who described it) it is a ‘tunnel’ connecting distant points in space-time. They are actually mathematical solutions to the field equations of Albert Einstein’s theory of general relativity.
Through these ‘shortcuts’ one could travel, always at speeds lower than that of light, to other distant places in the universe, and also to the future, not to the past, according to the principles of physics.
Wormholes are space-time ‘tunnels’, at the moment purely theoretical, through which one could travel to distant places in the universe and into the future
At the moment these space-time tunnels are purely theoretical, none have been discovered, but physicists do not stop proposing ways to cross them without closing their ‘throat’ due to gravitational attraction. The last two proposals come from Europe and the US.
One of the studies is published by physicists Juan Martin Maldacena from the Institute for Advanced Study and Alexey Milekhin from neighboring Princeton University (USA) in the journal Physical Review D. These authors use a model of the universe with more than four dimensions to explain how a human could cross one of these Einstein bridges -Rosen.
For its part, the other work, which appears in Physical Review Letters, is signed by the professor Jose Luis Blázquez Salcedo from the Complutense University of Madrid in collaboration with researchers Christian Knoll from the University of Oldenburg (Germany) and Eugen Radu from the University of Aveiro (Portugal). All three believe they have found a novel way to pass through a wormhole without resorting to exotic matter as before.
