Wild New Theory Suggests Wormholes Could Be Stable Shortcuts Through Space-Time

The simplest way to construct a wormhole is to "extend" the idea of a black hole with its mirror image, the white hole. This idea was first proposed by Albert Einstein and Nathan Rosen, hence the reason wormholes are sometimes called "Einstein-Rosen bridges".

This creates a tunnel through space-time.

Einstein and Rosen constructed their wormhole with the usual Schwarzschild metric, and most analyses of wormholes use that same metric. So physicist Pascal Koiran at Ecole Normale Supérieure de Lyon in France tried something else: using the Eddington-Finkelstein metric instead. His paper, described in October in the preprint database arXiv, is scheduled to be published in a forthcoming issue of the Journal of Modern Physics D.

Koiran found that by using the Eddington-Finkelstein metric, he could more easily trace the path of a particle through a hypothetical wormhole. He found that the particle can cross the event horizon, enter the wormhole tunnel and escape through the other side, all in a finite amount of time. The Eddington-Finkelstein metric didn't misbehave at any point in that trajectory.

Does this mean that Einstein-Rosen bridges are stable? Not quite.

General relativity only tells us about the behavior of gravity, and not the other forces of nature. Thermodynamics, which is the theory of how heat and energy act, for example, tells us that white holes are unstable. And if physicists tried to manufacture a black hole-white hole combination in the real universe using real materials, other math suggests the energy densities would break everything apart.

However, Koiran's result is still interesting because it points out that wormholes aren't quite as catastrophic as they first appeared, and that there may be stable paths through wormhole tunnels, perfectly allowed by general relativity.

DS9?

Par for the course in this generation...

Fiction = Reality

Bible = Fairy Tales

I never get any information if these worm hole—those stable paths through wormhole tunnels—can pass life through them without destroying life.

Sliders was good entertainment.

[datura]

It’s not difficult to imagine light speed plus travel in quantum reality, but mathematically nearly impossible in Einstein relativity.

Quantum is Godlike.

The more physics you know, the more you need to choose sides.

I choose God.

I like the Acme portable holes myself. They're based on the Looney metric.

Which one is racist? Black holes or white holes?

[Beowulf9]

That’s right.

[Hillarys Gate Cult]

Don’t forget “Stargate” and “Sliders.”

[CTyank]

There is also the roadrunner uncertainty principle, wherein the “beep beep” may be a truck moving at great speed in an opposing direction to the viewer of the hole.

Oh Lordy.

This is not a ‘wild new theory’. The possibility of an EPR bridge is as old as - well - E, P and R.

“...New Theory Suggests Wormholes Could Be Stable Shortcuts Through Space-Time”

C’mon man! OLD news.

Just ask William Shatner.

[SuperLuminal]

Will withhold my mirth, sarcasm, and doubt until I get the journal and read the paper...

[minnesota_bound]

The Ferengi were pulled into a wormhole and ended up with these ladies....

Thanks BenLurkin. Purty durned wild.

Without experiment its interesting math !

Doesn’t make its wrong or say they’re not on to something but without physical experiment it’s remains interesting math !
