We May Get Communications From Spacecraft Traveling Via A Wormhole

These hypothetical cosmic tunnels’ simulation demonstrates that wormholes don’t immediately close.

You won’t be returning back if you ever chance to fall into a wormhole in space. It will quickly close behind you. But according to a study published in the 15th issue of Physical Review D, you could have just enough time to communicate with the rest of us from the other side.

Although wormholes have not yet been seen, if they do exist they may provide fast access to far-off regions of the universe or perhaps to totally other universes. One of the most often researched wormhole kinds is exceedingly unstable and would collapse if any stuff were to enter it, as physicists have known for a very long time. However, it remained unclear how quickly that may occur or what it would signify for anything, or someone, entering it.

A brand-new computer programme now illustrates how one form of the wormhole might react to an object passing through it.

Ben Kain, a physicist at the College of the Holy Cross in Worcester, Massachusetts, claims that in the wormhole simulation, “you create a probe and you send it through.” Since you already know that the wormhole would collapse, you’re not necessarily attempting to get it to return. However, is it possible for a light signal to return in time to prevent a collapse? We discovered that it is feasible.

According to earlier wormhole research, the cosmic portals could be capable of supporting recurrent back-and-forth travel if they’re maintained by “ghost matter,” an extremely rare kind of stuff.

According to theory, ghost matter reacts to gravity in the exact opposite manner as regular matter does. This means that an apple made of ghost matter would fall up from a tree limb as opposed to down. Ghost matter is permitted under Einstein’s theory of general relativity but is probably definitely not real, according to Kain.

But when Kain simulated ghost matter passing through a wormhole, he discovered that instead of collapsing, the hole grew as predicted.

Kain’s simulation showed that anything composed of ordinary stuff was a different story; it would cause a collapse that pins the hole shut and leaves anything approximating a black hole behind. However, the process would go gradually enough to allow a fast-moving probe to send signals back to our side just before the wormhole totally closed.

If wormholes are ever discovered, Kain can’t see ever sending people through one. “Just a video camera and the capsule. Everything is automatic, he claims. The voyage will only go in one direction, but “at least we can capture some footage showing what this equipment sees.”

Sabine Hossenfelder, a physicist from the Munich Center for Mathematical Philosophy, advises that the concept should be viewed with a healthy dose of scepticism. “It necessitates the postulation of [things] that, for all we know, do not exist… Numerous mathematical operations may be performed that have no connection to reality.

Kain claims that despite this, the research is important because it may show how to create wormholes that don’t need ghost matter to remain open long enough for humanity to travel inside the universe or farther.
