Time Theory

Deja vu has a easy explanation that is firmly rooted in our mere four dimensional reality. Sometimes people go looking for extraordinary explanations for things that are much more simple.

All that happens when you 'experience' deja vu, is your brain stores a particular situation or instance in your memory before your conscious mind had finished processing it. Your brain does not work as one single thread the way we tend to think, but rather as many threads, somewhat similar to how a multi-core processor would work on a computer (although the different parts of your brain are much more specialized than that).

For further support of this, consider that you only ever have deja vu at the moment you experience whatever you feel you remember. You can never recall how or where you actually experienced that situation before, only that you have. If deja vu was really some sort of interference from alternate realities, you would expect them to act more like a premonition well prior to the given situation, or else even a sudden recollection of something that you know already happened. My point is, what is the significance of one moment over another to have a deja vu? Why would it only occur during whatever event? Consider that a deja vu will never tell you anything that you are not currently experiencing.

Another bit of support, although this is purely from my own experiences, but I rarely remember the specifics of a deja vu later. You will remember having had one, but it is typically hard to recall what it was about, much the same way that it is hard to remember dreams. That is, you can recall them fairly well when they happen, but afterwards it becomes more difficult. If I were to hazard a guess, I would say that this is because both dreams and deja vu are products of your subconscious.


Edit:
While we are on the topic of alternate realities though, I don't hold to the idea that there is another reality just like this one except that my eyes are a different color, or that I wore a different shirt today, or whatever. Physics isn't that simple, and in all probability if anything was different, it would be either something unnoticeable, or something so noticeable that the other reality could hardly even be called parallel anymore. By contrast, the whole proposition of branching realities raises so many questions that we have no answers to I hardly think that anything conclusive could be drawn from speculating on it. For example, physics is deterministic, so it would only logically follow for me to have say, green eyes (instead of brown) if something in my past changed to make it that way. Well then you say ok, so my parents had different genes too then maybe. And where does it stop? Its a huge chain reaction, that goes all the way back to what? The big bang?

The point is we don't have any clue whatsoever. The only thing we can say at all, is that realities don't branch of from other ones, because if they had the capability to be different, it makes much more sense for them to have branched off right at the start. Much more likely, is that if there even are alternate realities, they exist either with different laws of physics (which we couldn't even begin to explain), or that every reality has different starting conditions, or possibly both. The only thing at all that we can even theorize from all of this, is that under string theory gravity is explained as interacting across all of the realities, which would mean that they all interact in the 5th dimension. Gravity as we perceive it then, would just be the four dimensional projection of that force onto our reality. It would be logical to assume that other things then, possibly even ourselves, are part of something else in the fifth dimension, but I still don't think that would connect you to anything in any of the fifth dimensional realities.

i never watched that show, but...

i saw something like this on star trek. i know they've played with time theory on a few different series'.

voyager i know they had a fairly long story line with kurtwood smith as the captain of a ship that could manipulate time lines. and i think they had a couple other story lines that played with it.

the original series had the episode where kirk was caught in a transporter malfunction. he was sent to a time line where he had a goatee(which everyone knows is a sign of evil). the most recent series, enterprise did almost the exact same thing.

the next generation had one where warf was the only one aware of the fluctuating time lines. in the end a whole mess of enterpises from alternate reatlities apeared, including one where the borg were winning so they didn't want to go back.

the enterprise series had the temporal cold war story line.

There is also the possibility that everything already has a fixed path. This is all up for speculation and as such there are many different beliefs. This different dimension theory isn't exactly the most popular concept. Many religions believe that a god or gods created this earth for us to live on. While this can be somewhat deterred by evolution, it doesn't disprove a god. Reincarnation, fate, altering time are all possibilities. Perhaps all of these things are intertwined.

While we could have done this we instead do this. You could be at the point where you need to make a choice. There are a hundreds of different options for you to chose. Yet, you will choose this specific one. People call this fate. If another dimension is indeed real then that outcome could be completely different and will never merge with your own. In this mindset, a paradox can never occur because the outcome will always be different.

Also about the doppelganger, I doubt that they could exist. If they did exist they would not be identical simply because they are from a different dimension. This means that they have performed different tasks and may even look different as a result.

IT FUCKING HAPPENED! T__________-T I remember my friend posting she got her maid outfit yesterday~And today she said she got her maid outfit in the mail finally! And I said you told me this yesterday....And she said what? o-o No I didnt. Mail doesnt come on sundays....T^T;;

I agree with most of that, especially the part about any potential doppelganger. No one can be you except for you, because if all else fails you are at least defined separately in reality by the matter that comprises you (given that you would not share the same physical space with this 'doppelganger').

I would say on the religious stuff though, it is possible for a god to exist in a purely deterministic world. In fact, I think that if god did exist (as per western ideology), this would be the most likely scenario. This is because a supremely powerful all knowing god would not have much reason to allow chance into his creation. Given that he *is* supreme in power and in foresight, he could design his universe to grow how he wanted it. Evolution then, just becomes another part of his plan, as he would have expected it, and even counted on it. In this model, evolution can be said to exist and be true, and man can also still be said to be created by god (albeit indirectly).

I should mention I don't believe in god though, I'm just pointing out that the two concepts of evolution and god can coexist.
