First prototype of wormhole for travel over time

First prototype of wormhole for travel over time.

No longer just science fiction: the tunnels that allow to travel in space and time, the so-called wormholes, can now be built in the lab: Although on a very small scale, they show for the first time that crossing the time is possible and, pending future intergalactic journeys, promise to make the current nanotechnology-based devices more powerful.

The prototype, described online on the ArXiv site and published on the International Journal of Modern Physics D, will lead to an experiment conducted in Italy at the University of Naples Federico II.
“We built the prototype,” said the coordinator of the international research group, Salvatore Capozziello, Federico II of Naples, the National Institute of Nuclear Physics and president of the Italian Society of General Relativity.


The spacetime tunnels were expected in the 1930s by Albert Einstein and Nathan Rosen, in the theory known as “Einstein-Rosen Bridge,” and described enormous cosmic structures. “The starting point – said Capozziello – was to explain the existence of structures that, like the black holes, absorb all the energy of a system without returning it: in practice, it was faced with a violation of the principle “One of the possible explanations, the physicist said, assumes space time have holes :” It is a very fascinating and futuristic hypothesis, which implies the possibility of switching from one area to another space-time as having to connect parallel universes between them. ”

The experiment

The problem is to test this with an experiment. “Our idea – the physicist said – is to be able to simulate gravitational effects at lower energies, and we wondered if this would be possible to reproduce a wormhole in the lab. “The prototype is tiny. It was obtained by linking two sheets of the world’s thinner material, graphene, molecular bonds and a nanotubes. The obtained structure is neutral and stable, in the sense that it does not enter anything and nothing comes out, but when defects are introduced, incoming and outgoing currents are generated.

“Moving on cosmic dimensions, we could consider an observer that with his shuttle approaches a wormhole as an element capable of disturbing the structure. In this case, he noted, it would be possible to move from one part to the other of the space-temporal tunnel, as like as send signals from one part to the other.”


The possible applications

While on the one hand, a space-temporal tunnel obtained in the lab flies the imagination, the possible applications are very concrete:  “graphene sheets allow control of incoming and outgoing currents” and now the goal is to obtain a prototype reproducible on an industrial scale.

“Producing a similar structure means transmitting signals in an extremely precise way at the atomic level,” said the expert. “The project is under way with the group of Francesco Tafuri of Federico II’s Physics Department. ” For example, nanostructures could be able to transmit signals instantly as the electric current would go blank.
