Thoughts on "parallel universe"

Recently saw the watercress recommended a "parallel universe" film, is said to be a U.S. drama, the result of a film came out.
The story of the film is still novel, although I think vainly disobey feeling is very strong ...
It always emphasizes a concept: we do not travel through time, but to another space. I am very much in favor of this, I also think that the passage of time is not likely, or meaningless, hawking that bastard (or Einstein) said what more than the speed of light can reverse the time, anyway blowing good and not illegal. I think time and space is just a concept that is formed by the development of things.

As an example:
Get a toy car from a to B point, this thing went through a so-called time period (from T1 to T2), now we have to return the toy car from B to point a (here we have to learn the concept of ideal experimental state), then we now call the time is T1 or t2+ (T2-T1)? If it was T1, would we have "crossed the time"? If it is t2+ (T2-T1), now the whole world is the same state and T1, that is, I only need a means to restore the development of things to the original state, can achieve our so-called "through Time" concept, or this time wear not through the time or anything, has no matter.

In fact, there are similar questions in the "Frontier of Tomorrow".
Omega/alpha's blood gave Cage the ability to reset the time of the day, and we might as well say that it is a capability to backtrack all things into a certain state. Have studied the computer, has researched the go program's affirmation to know this is the matter, uses a stack we can let the chess "through the time", actually we just let the chess backtrack to a certain state of the stack. If this stack is copied over to other places for development, when these stacks are developed in parallel, we say that these discs make up a parallel world. Who said the quasi-we are not a computer stack program?

How many stacks of shared memory is that building? :-)
