I,ve read about it in "The brief History Of time" and also in a fiction story. Can you tell me something about it?

Parallel universe is a replica of the universe we live in. It is defined in order to explain the concept of time travel and a famous scenario called the " Grandfather Paradox". For instance think of the following scenario : If a person can travel at the speed of light he will be able to travel back in time. So if he shoots his grandfather before his grandfather has met his grandmother, then how will he the person exist in the first place? So in order to justify time travel and in order to explain the above scenario, the Parallel Universe concept was introduced which says that when you travel back in time and change the course of things you will be in a parallel universe where things are similar to the universe that we live in, but with slight modifications. Morever every person on the universe will have a parallel universe so there as many parallel universe as the number of people on the universe.

A parallel universe is the concept that there is another Earth (or many of them) where you and everyone you know would also exist but your lives and general circumstances would take a different spin than anything you know to be true and real as of right now.
If you check out the Sliders tv show, either reruns on the SciFi Channel or at the local video store, they show a pretty good example of that.

According to the theory of relativity time is subjective. The effect of gravity can warp or alter it. In a totally gravitationless field, time (in theory) does not exist, and in a massive gravitational field like a black hole time passes so quickly that in essence it also ceases to exist. Since time is not a given then anythingthing that can happen does happen, and if it doesn't happen here then it must be happening somewhere else i.e. a parallel dimension. But this can work both ways, for any action there are an infinite number of possible reactions, but for any reaction there are an infinite number of possible original actions. Therefore anything possible can, has, and will happen.

The Parallel Universe is defined many different ways since there are different theories about it. One definition states that it is another universe which can also be called an alternate dimension. It is a hypothetical universe existing on a separate plane from ours. It is hypothetical because we don't have any proof that it exists yet, just supposition. But there are other theories that state that there are many different universes, one for every event that could have happened. For example if you were asked to attend a movie then there would be two different outcomes. One outcome is that you go and one is that you decline. In one universe you would go and in another you wouldn't. This might mean that universes go on to infinity.

A universe "alongside" ours in a dimension besides the ones that we are ordinarily familiar with (up-down, left-right, back-forth, past-future).
Strictly speaking, all particles that can exchange energy with each other must be in the same universe together. Therefore, a more fitting phrase would be "parallel section of reality".
Hue Everett theorized the Many Worlds Interpretation of quantum dynamics, in which what we normally think of as our universe is called a "world" and what we normally think of as "all possible paths of reality" is called "the Multiverse". Under the MWI, a parallel universe is a "world" in the "Multiverse".

A parallel universe is called that because it exists alongside this universe, running 'in parallel' with it. The idea is that parallel universes are not accessible simply by flying through three dimensions; you need a fourth spacial dimension through which to leave our three-dimensional universe and go to another one. The idea appears in many science fiction stories, often associated with time travel.

Scientists now feel that we have unlimited Parallel universes and we are living in one of them. These universes contain space, time and strange forms of exotic matter. Some of them may even contain you, in a slightly different form. Astonishingly, scientists believe that these parallel universes exist less than one millimetre away from us. In fact, our gravity is just a weak signal leaking out of another universe into ours.

A parallel universe is simply another universe that exists along side this one. There are 11 such universes known today, and probably many more.

a parallel universe is a universe that is sot of a twin of our own universe.if you were to travel to this alternate universe,you would an almost exact twin of our planet,city,and relations.in parallel universes,however,there is usually minute differences.for example,in an alternate universe,instead of being a website,Yahoo could be an exotic animal people keep as pets.

somthing cannot be created from nothing. from an absolute zero only a positive and negative can evolve. for every particle there is an anti particile. for a universe there should be a parallel universe which is the negative of the existing one
