Wormholes are hypothetical tunnels that, in theory, would allow time travel to take place.

A group of scientists from the California Institute of Technology (Caltech) was able to recreate a “small wormhole” in the laboratory. The phenomenon, which has never been identified in reality, is a famous hypothesis of quantum physics.

Our current theoretical knowledge states that this hypothetical tunnel would allow for “time travel”, functioning as a “shortcut”, or else a “bridge” between one place and another in the Universe.

The simulation of the structure was made with a black hole at each end, since these cosmic singularities supposedly cause distortions in the fabric of space-time, thus creating the necessary conditions for the formation of a wormhole.

The scientists made the theoretical model using a quantum computer, declaring the experiment a success by being able to deposit information at one end of the tunnel, and collect it at the other end.

The signal scrambles, turns to mush, becomes chaos, and then recomposes and looks pristine on the other side. Even in this tiny system, we could sustain the wormhole and observe exactly what we expected,” he explained. Maria Spiropuluco-author of the study, as reported by NewScience.

Little revealing but impressive

According to the researchers involved in building the computer simulation, the modest wormhole they created (which, fortunately, did not disrupt the fabric of reality), taught them nothing they didn’t already know.

Even so, it is a “technical achievement” of great relevance, as commented by Daniel Harlowa physicist at MIT (Massachusetts Institute of Technology) who was not involved in the study, in an interview released by The Guardian.

This is because this simpler modeling can open the way for simulations of more complex quantum theories to be built in the laboratory.
