I wondered about multiple line lines, non-linear time, singular time and positive/negative time, starting with the question, "does time exist?".
I decided that time as we know it, does exist, since time is just a label we put on the measurement between start and end points that we are measuring. I also decided that time is relative to the things that we are measuring, as a yard stick. I don't think time can be said to exist, though, because we use time as a variable to describe something, not a constant that we can hold.
Whilst considering different types of time-lines (linear, non-linear, mutliple, +/-) I reached the conclusion that there must be multiple time lines and wondered how many there might be.
I decided there couldn't only be one time line since that would be far too infinity like, and therefore could only be relative to parts of itself, which would then have times, and therefore many time lines would exist, each instance having its own sets of parameters.
That thought provoked the rejection of any other theory whilst I scraped around in my head for the bigger picture of such an idea.
The idea is that each atom, or particle, or piece of anything that contains substance (call it a being), has its own time line. Sometimes actions on that time line can be predicted because they follow suit of other actions that have taken place on other time lines, however, the end may be different for each occurence of the same action - which gives us chaos.
The relation of time to each being is personal to that being. One cannot relate time for another being unless one applies that beings rules of time to oneself. However, one can disrupt another being's time through one's own actions, for example, by interrupting the other being's action.
Therefore it is possible that there are many many universes that have actions taking place at the same time as the other universes - but maybe with different endings. A bit like a mandlebrot.
To prove such a theory is probably similar to proving there is a god. Maybe if we look for clues we can guess that it could be right - deja vu, out of body experiences, ghosts, stuff in dreams and how some amazing thoughts ever get into our heads. They are all natural phenomena that are often explainable unless somehow, time lines have crossed or matched each other in that short instance.
Could this really happen?? How could two time lines cross and how do we decide which time lines we're on?
Simple, we all have our own time line and sometimes we steer ourselves towards events through positive thinking, belief, a goal or some other state of mind that makes us go after something important.
Things that you consider to be bad luck are often things out of your control, a crossing of time lines where yours met a bunch of others that resulted in a negative action for you. Good luck is supposedly the opposite. Both have the ability to be looked back upon and avoided, but neither were planned by you.
When you live with someone you can often predict things they are about to say, finish sentences for them, carry out actions in preperation for something you predict they are going to do and you still get surprised by this because you didn't intentionally plan it.
Maybe the answer to life,the universe and everything is intention. If you can predict another being by being close to it, and so on, for every being there is, there can be harmony, and each being could exist for longer except for the fact that each being is responsible for its own actions (the chaos bit). Therefore the only thing that lasts forever is nothing because it isn't there - I suppose that's the reverse of everything.
As for time travel, this theory suggests one cannot travel in one's time to a previous time unless one can experience another instance of one's lives in another universe.
Why would actions take place at the same time? How can one catch a glimpse of an action in a time line that conflicts with one's own time line?
It must have something to do with nothing, and everything being its opposite. The multiverse is a living organisation. Life exists to protect life, evolution is the result of this action.
If the multiverse exists then why wouldn't it thrive to survive? We are such small parts of the universe, and there are many smaller parts, but we can effect much bigger parts, in the same way that some miniscule particles can effect us (gas, poison etc). Because we are intelligent we have some control over the things that effect us and we can make plans that will improve our chances of survival.
In such behaviour, other universes would be dieing and being created throughout our lives. If your time line crossed with a time line in such a universe, you would get the impression of traveling in time, although you would simply be witnessing a different instance of yourself.
If there was a way to really travel in time, the answer would be to share a multiversal existence. For your mind to be one with each instance of yourself (and the same application for each being).
This would give the multiverse the best chance of survival, but also a greater chance of failure, unless the multiverse is intelligent.
What sort of intelligence could do such a thing?
The natural behaviour of a being, is to multiply. Some things do not need to multiply because they are replaced by another instance through some other means than breeding, such as blood cells do. For intelligent beings, there is often a choice about breeding, but natural beings are designed to thrive, or they become nothing. I can't prove that we share the minds of other instances of ourselves, but it might explain those things that we call the paranormal.
What about God? Whatever he is, I don't think he's a person. This theory does allow for cause and effect, and therefore behaviour (which religion teaches) is a part of it. If we lived a perfect life, that harmony that I mentioned earlier would become more of a reality...but that's another discussion altogether.
