A wormhole is named because it's thought to resemble a tunnel made by a worm boring through an apple. Theoretically, wormholes could allow for faster-than-light travel, but there is no evidence to suggest they can be used for time travel. Time travel through wormholes remains a concept largely explored in Science Fiction.

It came from one of the earliest metaphors for a wormhole. I can't remember who it was, but some time after our buddy, Einstein and his student, Nathan Rosen proposed the idea of the theoretical possibility of the Einstein-Rosen Bridge, somebody described the idea as being like how a worm burrows a hole through an apple instead of crawling around the outside of it, saying that the hole is a new, quicker way from point A to point B. This description was to explain how this guy thought an Einstein-Rosen Bridge could be used for faster than light travel. Of course, Einstein and Rosen never actually thought a bridge large enough to allow the passage of anything of any real substance through it was possible; it was thought of as merely a theoretical possibility on a subatomic scale.

Anyway, ever since this, the idea of a TRAVERSABLE Einstein-Rosen Bridge through warped space-time has been called a wormhole, although recently the term "wormhole" has pretty much replaced the term "Einstein-Rosen Bridge" (probably because it's a lot easier to say in a sci-fi movie!).

I'll add new stuff to my friend's answer above: This is how we believe time travel backwards is possible. We know forwards is possible and have done it. It's called space dilation and some guy is actually ten minutes younger than other people on Earth, but we haven't been able to get great leaps in time forward.

Anyway, divagating from the original subject of this question, I'd like to explain my beliefs in how one could use a wormhole, travel back in time, and theoretically kill his grandfather. I personally don't believe in the grandfather paradox. I believe one could actually kill his grandfather and not create a paradox and I shall explain:

First, a paradox cannot occur if time be linear. To believe in a paradox, one would have to believe that everything in his life is predestined, i.e. that it has already happened and that time forever repeats itself, but on different planes of consciousness. This is not the case in my mind. If we believe that time is predestined, then we must also believe that we are just going through the motions like something on television. I believe that time is linear and that we could jump onto different planes of time once they have been formed, which erases any paradoxes and here is why:

Now, just because time is linear doesn't mean that it doesn't have little knots or loops, what I call slubs, in it. For instance, think of time as a ball of yarn: the beginning end is where time starts and the string of yarn unravels from the skein as time moves forward. Well, yarn, just like time, is not a perfect creation. There are slubs in all strings of yarn just as there are in time and space. These "slubs" act like little knots in time wherein space-time has looped over itself. This is how a wormhole works in my mind. The slub has wrapped itself around so that, in theory, multiple planes of time be existing in the same space and time; therefore, for our time traveller, the years 1932 and 2010 are actually touching each other and the wormhole is a gateway or time-gate in essence. This would be how I believe we could use wormholes to travel through time if we were ever to obtain empirical knowledge of their existence and were able to harness their energy and properties. Furthermore, these are my precepts behind how wormholes work when appertaining to time travel and they should not be acribed as facts. They are just my personal views on this topic--my own little theory, as it were. Without further descanting, let's move on, shall we?

So we believe now that time is linear and that events have never occurred in the future. Now, that means that one could actually be born and go back in time to kill his grandfather. It's like a movie. If we were making a movie and, towards the end, we didn't like an earlier scene, we could go back to that point and change it, thereby changing every scene following that instance though, even if it were just a minute change.

The fact is there would be no paradox because that time, the original history, would actually have once occurred: this person would have still been born and he would have still made a conscious, freewill effort to go back in time to kill his grandfather. The fact that one has changed time wouldn't erase the fact that he had still been born. The scenes from the original movie would still be there, but would be recorded over, starting a new chapter in the future and affecting everything else.

In my theory, that person, the time traveller, is still aging and still moving on his own plane of time. His time in the year 2010 has not stopped moving just because he has travelled to 1932 to kill his grandfather. Now, if we believed that time has already been predestined, then we would also have to believe that this event to kill one's grandfather has already occurred in the year 1932 and that a blip in space-time has occurred and that the cycle continues to repeat itself for all of eternity. This is way too complicated. Remember Occam's razor--that the simplest answer is the one to be preferred.

If we take Occam's razor and put it to the test with time travel, we can see that there is no paradox--that time is linear, with the occasional slub, and that travelling through time only causes one to change to a different plane, but time continues to move forward. Again, if we believed in paradoxes then, if one were to go back in time, he should never age because his time has stopped. Really, though, he would not be Methusala if he were to go back in time. He would still age. His time in 2010 would still move forward. Time would never stop and it shall never stop. Time shall always continue forward and there is no way to stop it. It can only be slowed down theoretically.

All right, so if this person were to be successful in killing his grandfather, he would change the scenes of this "purported movie" between 1932 and 2010. I believe he would then disappear because he would not have been born from his original father, but I don't think he would totally vanish. Remember the theory of a higher mind--a creator of this madness in the universe. He would still have plans for this person. I think one would appear back in the year 2010 with no memory of what had happened, but be on a different timeline. If this person had originally been born in the year 1986, he would probably still be born in 1986, but to a different mother and father and his life would go in a different direction.

Remember, no paradox has occurred because the future is not predestined and, in the original history, this person had made a freewill, conscious decision to murder his grandfather before his father was born. All this person has done is record over the original history; thus no paradox. His memories of his new life would fill his head and he would have no memory of his time travel experiment. Life would totally be changed. Every action that his grandfather and father had played originally would be changed and that would affect everyone else's life like a ripple effect when one throws a stone into a pool of water. Again, what happens to the ripple? It diffuses, right? And the universe or God would do everything it or He could to diffuse the ripple effect as best as possible, but, remember, a ripple is not continuous. It eventually loses strength and disappears. His changing time would not cause universal bedlam; the universe would correct itself, i.e., Occam's razor---the simplest answer to phenomena is usually the correct answer. We shouldn't believe that this would cause bedlam in our universe. We should think that our universe is vastly smarter than we are and has already obviated such antinomies.

Does a wormhole bring you to different galaxys?

In the law of physics, wormhole can possibly exists, but no one ever found a wormhole or seen. there is no evidence that wormhole can exist. And if wormhole exists,it wont bring you to other galaxy, but you go to other universes through it and also travel in time.


What is a wormhole Explain about it in simple scientific language?

A wormhole is a tunnel that connects two point's in the space time continuum. I ,a 13 year old boy, have created an experiment that can make a wormhole that we can use to time travel. If you want to read the experiment plan then follow this link.. http://www.ireport.com/docs/DOC-367891#


Is time travel possible through a wormhole by providing it enough energy to open up?

Time Traveling through a wormhole could be possible but it's not if Wormholes exist, it maters that where the wormhole ends to and what time period. Let say if we had a rocket and it took 50 earth years to get their at 99.9999999% of the speed of light, once we enter it, we could be chucked through any time period in the past or future. Worm Holes ain't like computers, they wont take you to an exact time period.

How does wormholes affect time travel?

Time travel is not possible. The effects of a wormhole would depend on the author of the story you are reading.


How is the term 'wormhole' defined?

A wormhole is a theoretical passageway through space and time connecting separate regions of the universe or in the case of the multiverse, separate universes.


Where can a wormhole take you?

A wormhole, if you were to dive into it, can take you anywhere in space or time. So say the science-fiction delighters, who ignore the fact that you can't survive a leap into a wormhole. Wormholes are hypothetical, mathematically possible but unobserved and therefore hypothetical. If a wormhole were to take you back in time, it could only take you as far back as the age of the wormhole. A wormhole has two ends, an in and an out. Imagine the out end oscillating at the speed of light from the moment the wormhole forms. Time stops for that end of the wormhole relative to the in end which oscillates at a leisurely pace in this illustration. Imagine you leave the wormhole from its birth for a year and then leap into the in end. You would emerge from the out end a year into the past. Imagine leaving the wormhole for a century. You could jump in and emerge from the out end a century into the past. But you can't travel back to a time older than the wormhole.


Can a wormhole make time travel possible?

Some theories suggest it may be possible, others deny it.


Can a human go through a worm hole?

No ______________________________________________________________________ well, the answer is no for now, a glaxy is a straight line thorugh to the other side but when a worm hole is made it curves the galaxy to a large U allowing passagee through instead of around, however we do not yet have a ship the can stand the quick change in speed nd it would tear us apart into small bits but pieces wuld make it through.


Do you travel at the speed of light in a wormhole?

Nobody has measured this, and it isn't even known whether a wormhole actually exist. Probably not - they are very hypothetical. The idea of a wormhole, however, is that it would let you travel instantly, or almost instantly, from one point to another, distant, point. From the point of view of an outside observer, this would let you travel much faster than the speed of light - and therefore, it would also be possible to travel backwards in time.


Is time travel possible through Wormholes?

Wormholes are highly hypothetical; there is no evidence that they exist, or even that they can exist.


What is the wormhole capable of?

Since there is no definitive proof of their existence and thus there is no way to experimentally confirm or disband our theoretical formulae and calculations nobody knows. If you are to believe the original theory behind the wormhole, the concept of the Einstein-Rosen Bridge, come up with by Albert Einstein, then a wormhole is very, very, very, very, very tiny and exists for such a short period of time that nothing is ever really going to get through it. Beyond Einsteins idea, modern theoretical physicists believe there is a great number of things a wormhole could be capable of. It is thought that if you could make an artificial wormhole by expanding one (with ridiculous amounts of hyper-concentrated planck energy), propping it open (possibly with some form of exotic matter) and (according to Stephen Hawking) absorbing the massive radiation "feedback" that such a warping of spacetime creates the a wormhole could theoretically: 1. Transport matter, electromagnetic radiation and energy vast distances, technically, faster than the speed of light without actually passing the speed of light. 2. Travel through time (related to point 1 as a wormhole is a passage through SPACETIME, not just space). 3. Travel to parallel Universes! In every case above it is heavily debated whether or not a wormhole (if one could be created) could be used to get to a particular place, time or universe or combination of these three. It is entirely possible, indeed likely, that a wormhole would just dump its passengers at a completely random point in timespace! If this is true it would really be a rather poor form of travel.
