How is a wormhole created?

We place two massive objects in two parallel universes (modeled by two branes). Gravitational attraction between the objects competes with the resistance coming from the brane tension. For sufficiently strong attraction, the branes are deformed, objects touch and a wormhole is formed.

How does the wormhole work?

Wormholes connect two points in spacetime, which means that they would in principle allow travel in time, as well as in space. In 1988, Morris, Thorne and Yurtsever worked out how to convert a wormhole traversing space into one traversing time by accelerating one of its two mouths.

How could you create a wormhole?

From my readings, there are two (highly theoretically, of course) ways of creating a wormhole: 1. Focus a galactic-level beam of energy/mass at a single point. This will create a naked singularity that would somehow create a twin singularity elsewhere in the universe. A tunnel would exist between these singularities.

How do you open a wormhole?

To travel through time, all you need to do is open a wormhole in space-time and step through it. And to do that you need a magic ingredient called ‘exotic matter’, which is repelled rather than attracted by gravity. The hitch is that no one has the remotest idea how to make exotic matter.

What is a wormhole, and how it is formed?

A wormhole is a theoretical passage through space-time that could create shortcuts for long journeys across the universe. Wormholes are predicted by the theory of general relativity. Certain solutions of general relativity allow for the existence of wormholes where the mouth of each is a black hole. However, a naturally occurring black hole, formed by the collapse of a dying star, does not by itself create a wormhole.

How to open a wormhole?

If you thread the wormhole with a cosmic string, and allow the string to pass along the outside edges of the black holes and stretch out of either end all the way to infinity, then the tension in the string prevents the charged black holes from being attracted to each other, holding the two ends of the wormhole far away from each other.
