Are worm holes just a theory and how could they be possible where would they lead to?

Answer 1

Worm holes are strictly theoretical features---there is absolutely NO evidence that they truly exist. Anybody tries to tell you differently is either blowin' smoke or just plain dumb.

Basically, worm holes are implied by some solutions to Einstein's relativity field equations. Passage through a worm hole would NOT require faster-than-light travel. All a worm hole would be is a kind of short cut through spacetime. To get an idea of this, take a piece of paper and put two dots on the page. Now fold the page so that both dots are directly opposite each other. You'll notice that the distance between them is considerably shorter than before you folded the paper. A worm hole would extend through that open space between the fold.

Instead of copy-and-pasting page after page of info from Wikepedia like another "answerer" did, here's the basic equation for a simple worm hole--

ds2 = − c2dt2 + dl2 + (k2 + l2)(dθ2 + sin2θdφ2)

Answer 2

Yes, they are just a theory. It has to do with the topographical manipulation of spacetime using very complex math. Since math doesn't rule them out, the theory exists. Where they would lead to is another place in the universe, a sort of short-cut. Instead of going the long way around in a straight line, you would travel through "warped hyperspace." Like drawing two points on opposite sides of a piece of paper: You can connect the points by drawing a straight line, or you can just curl the paper around so that the points touch. That's your wormwhole. You cheat by going from a "two-dimensional" piece of paper into three dimensions. In this case, you would go from four-dimensional spacetime to a fifth dimension. Yeah, the mind boggles.

Yes they do acure I can not exsplain them myself but I can do the next best thing here is a link to that: --> http://www.hypography.com/topics/wormholes.cfm

Answer 4

No, they are theory, here are some tidbits from the website I feel is very good. This is just a part of what was said there!

Intra-universe wormholes connect one location of a universe to another location of the same universe (in the same present time). A wormhole should be able to connect distant locations in the universe by bending spacetime, allowing travel between them that is faster than it would take light to make the journey through normal space. See the image above. Inter-universe wormholes connect one universe with another [1], [2]. This gives rise to the speculation that such wormholes could be used to travel from one parallel universe to another. A wormhole which connects (usually closed) universes is often called a Schwarzschild wormhole. Another application of a wormhole might be time travel. In that case it is a shortcut from one point in space and time to another. In string theory a wormhole has been envisioned to connect two D-branes, where the mouths are attached to the branes and are connected by a flux tube [3]. Finally, wormholes are believed to be a part of spacetime foam [4]. There are two main types of wormholes: Lorentzian wormholes and Euclidean wormholes. Lorentzian wormholes are mainly studied in semiclassical gravity and Euclidean wormholes are studied in particle physics. Traversable wormholes are a special kind of Lorentzian wormholes which would allow a human to travel from one side of the wormhole to the other. Sergey Krasnikov tossed the term spacetime shortcut as a more general term for (traversable) wormholes and propulsion systems like the Alcubierre drive and the Krasnikov tube to indicate hyperfast interstellar travel.

Theoretical basis
It is unknown whether (Lorentzian) wormholes are possible or not within the framework of general relativity. Most known solutions of general relativity which allow for wormholes require the existence of exotic matter, a theoretical substance which has negative energy density. However, it has not been mathematically proven that this is an absolute requirement for wormholes, nor has it been established that exotic matter cannot exist.

Recently Amos Ori envisioned a wormhole which allowed time travel, did not require any exotic matter, and satisfied the weak, dominant, and strong energy conditions [5]. Since there is no established theory of quantum gravity, it is impossible to say with any certainty whether wormholes are possible or not within that theoretical framework.

Traversable wormholes
Lorentzian traversable wormholes would allow travel from one part of the universe to another part of that same universe very quickly or would allow travel from one universe to another universe. Wormholes connect two points in spacetime, which means that they would allow travel in time as well as in space.

Wormholes and faster-than-light space travel
Often there is confusion about the idea that wormholes allow superluminal (faster-than-light) space travel. In fact there is no real superluminal travel involved. Assume that the wormhole connects two remote locations. While traveling through a wormhole, subluminal (slower-than-light) speeds can be used. The time in which the distance was traveled would appear faster (due to the fact that it goes through a line(a-b) in a curved space instead of going through space outside of the wormhole, which is like going through the center of an apple rather than going around it on the outside, hence the name wormhole) than it would take light to make the journey through normal space. In other words, while you might need to run to get around a mountain in a certain time, you can walk comfortably if there is a tunnel through the center; no additional speed is needed, because the subjective distance is shorter.

Wormholes and time travel
A wormhole could allow time travel. This could be accomplished by accelerating one end of the wormhole relative to the other, and then sometime later bringing it back; relativistic time dilation would result in less time having passed for the accelerated wormhole mouth compared with the stationary one, meaning that anything which entered the stationary wormhole mouth would exit the accelerated one at a point in time prior to its entry. The path through such a wormhole is called a closed timelike curve, and a wormhole with this property is sometimes referred to as a "timehole."

It is thought that it may not be possible to convert a wormhole into a time machine in this manner, some mathematical models indicate that a feedback loop of virtual particles would circulate through the timehole with ever-increasing intensity, destroying it before any information could be passed through it. This has been called into question by the suggestion that radiation would disperse after traveling through the wormhole, therefore preventing infinite accumulation. There is also the Roman ring, which is a very stable configuration of more than one wormhole. This ring allows a closed time loop with stable wormholes. The debate on this matter is described by Kip S. Thorne in the book Black Holes and Censorship Hypothesis.

Schwarzschild wormholes
Wormholes known as Schwarzschild wormholes or Einstein-Rosen bridges are bridges between areas of space that can be modelled as vacuum solutions to the Einstein field equations by sticking a model of a black hole and a model of a white hole together. However, this type of wormhole is unstable enough to pinch off instantly as soon as it forms.

While the equations of General Relativity suggest that a Schwarzschild wormhole could be stabilized by holding its "throat" open with exotic matter (material that has negative mass), it would still be impossible for a traveller to go through this type of wormhole because they can only go through an event horizon in one direction, and both ends of the hole have an event horizon. This leaves the traveller trapped in the middle of the wormhole.

Before the stability problems of Schwarzschild wormholes were apparent, it was proposed that quasars were white holes forming the ends of wormholes of this type.

Wormhole metrics
This article or section is in need of attention from an expert on the subject.
Please help recruit one, or improve this page yourself if you can. See discussion page for details.
Theories of wormhole metrics describe the spacetime geometry of a wormhole and serve as theoretical models for time travel. A simple example of a (traversable) wormhole metric is the following:

ds2 = − c2dt2 + dl2 + (k2 + l2)(dθ2 + sin2θdφ2)
One type of non-traversable wormhole metric is the Schwarzschild solution:

Wormholes in fiction
Main article: Wormholes in fiction

The Bajoran wormhole From Star Trek: Deep Space NineWormholes are a popular feature of science fiction as they allow interstellar travel within human timescales. It is common for the creators of a fictional universe to decide that faster-than-light travel is either impossible or that the techology does not yet exist, but to use wormholes as a means of allowing humans to travel long distances in short time periods. Military science fiction often use a "jump drive" to propel a spacecraft between two fixed "jump points" connecting solar systems. Connecting solar systems in a network like this results in a fixed "terrain" with choke points that can be useful for constructing plots related to military campaigns. The Alderson points postulated by Larry Niven and Jerry Pournelle in Mote in God's Eye and related novels is an especially well thought out example. The development process is described by Niven in N-Space, a volume of collected works. David Weber has also used the device in the Honorverse and other books such as those based upon the Starfire universe, and has described a 'history' of development and exploitation in several essays in collections of related short stories.

Wormholes feature prominently in the television series Farscape. They are both the cause of John Crichton's presence in the alien universe, as well as the reason for many of the events that subsequently take place. In Stargate SG-1 and Stargate Atlantis, a wormhole is created by a Stargate, and as opposed to other science fiction programs, many of the technical issues facing wormhole travel are addressed.
