This article is just a theory based on my analysis of things, events and thought process afterwards. Its existence is not proven yet. It's an endeavour to search for answers of some unanswered questions.
As you all may know, there is an existing theory which tells that to determine one's location in the universe we need to know the x,y,z coordinates of that person/thing/place, along with the fourth co-ordinate "time" (ofcoarse, a reference point being chosen beforehand) which brings the theory of parallel universes in light i.e. one person can be at the same place but if you will change the time co-ordinate then he will be in some other universe. So, actually there are so many parallel universes present simultaneously. there are universes for past . present and future. one travels from one universe to another as time passes automatically. he doesn't experience this but actually he is travelling all the way throughtout the life time.
But, here comes some addition to the parallel universe' theory. Aacoording to my analysis there is one more parameter i.e. the fifth parameter of ones location. Let me explain in coming lines.
Take an example here, right now where ever you are and whatever you are doing, you have plenty of options to do next e.g. you can go for a coffee, take a nap , read/browse/gossip/games etc. but you'll choose any one thing according to your wish. Similarly everyone else does have plenty of options to do in the next moment. so, for each of your choices there should be a different universe because if you choose any one thing you can go to one universe and if you choose another you can go to other. similarly for everyone there are different universes for the options they have to do next. so actually the number of universes possible for next moment would be billions of billions (because for each option of one's there would be all universes of others so actually the total number of universes is a multiple of all the options of all the living things ).But one travels to the universe which is determined by the choices made by all the living beings including his own(including the outcomes of all previous choices made by all). So, what if he or someone else wud have opted for something else other than what he chose actually. the universe would have been changed. So, there must exist that universe which actually didn't got traveled by all but could have been. Hence, there is one more co-ordinate of one's location which is the fifth co-ordinate , I name it as "i".So, I'll name this one more axis as imaginary axis as it is not the one which can be felt as compared to other axes(x,y,z, time).
Now, according to current theory of parallel universe, time travel have some problems like grandfather paradox i.e. if one travels to past and kills it's own grandfather than his father would never come in existence and he himself too. so, its a paradox. But, this can be explained by taking imaginary axis in consideration, you can see that with x,y,z,time being fixed there would not be any universe which would be having the scenario of his grandfather being killed by a person/thing absent in all the previous universes. So, actually this is not a problem and can be ruled out. But there is one real problem with time travel.As you know there should be something which should be constant throughtout the course of time, what it can be, it can be something which can neither be created nor be destroyed , It's the soul. so the number of souls present should always be constant at any point of time in a universe. But by time travel you are violating this law because you are increasing the number of total souls in one universe and decreasing in the other. That's not possible. So, the only way to do time travel you need to exchange one soul from that universe to this universe and then only you can move one soul from here to there( Also you need to find out the imaginary co-ordinate at that point of time which was really lived and known to the world right now (assuming current universe as real) that's again is very difficult ) . So, actually it's not time travel rather it's universe travel . you are travelling between universes. or more precisely parallel universes.
We can have answers of lot many questions by this theory, I leave it upto you .It's an inception, let's see where it goes...
Feel free to discuss it further with me, as I am always available for that ( the whole world is celebrating the arrival of new year and I am wiriting this whole theory here.. So you can clearly understand my availability :) )...
