Warning: Intellectual exercise ahead
Anyone feel like bending their brains around time travel? I think I've got a fairly solid formulation for why, if time travel exists, it does not inherently restrict free will. (I.e., free will may or may not exist, but if it does, time travel won't change that.)

Also, interesting thread in that post about whether perfect knowledge of the universe is possible (short answer: IMHO no).

Are we talking form the philosophical vantage of time travel and it's effects on the completely man-made (and thus inherently fatally flawed) "time stream', or actual Physical effects upon some kind of Time-Space matrix (which I do not really believe in to begin with)?

For one, I will refute that the universal 'force' of Time even exists. For another, Time travel has to be possible or the concept would not exist.

It just does not work with a linear reference like human perception.

Perhaps there is no such thing as 'time'.

Perhaps, instead of changing the direction of the dot, you just move the bit of paper?

In fact, my own theories about time travel are pretty closly linked with my theories about multiple universes. The old trousers of time thing y'know?
And every time you change your mind, you change the future. It would, i thing, be relativly easy to go backwards in time, but you have little to no chance of getting back to where you started because a:just by going back in time you have caused a million 'new' universes to come into existance, and b:you would need to know, and predict the outcome, of every decision of every other person on the planet in the past just to get back to where you started.

Uh, just like that tree someone mentioned.

I think.

Actually, i enjoy picking at plot holes in time travel stories far more than i do making up my own time travel theories...

On Time Travel:

If one were to think more along the line that "time" is more a percieved idea, then one begins to explore ways to change the way in which one travels through it.

That said, I have managed to travel backwards in an "astral" form. It was only about a week backwise and I do have a witness (well, several, if you wish to consult some ravens as well) to this event.

On Perfect Knowledge of the Universe:

As many know, I tend to think more in the terms of "multiverse"
I do not believe there is any living being (of the fleshy type) that is able to retain that amount of knowledge. In my own experience I find that I will "just know" thinngs. Of course that also depends on how much I am Listening at the time :)
No one being is able to retain so vast amount of knowledge, which is why it is handy to have "allies" throughout the multiverse (and yes, I do consider the spirit world to be a part of the multiverse, after a fashion).

The problem is a mechanism for traveling backwards in time.

Otherwise, it doesn't really matter. Do whatever the hell you want when you go back in time because it won't actually affect history too much (at least, our perception of it) because whatever you did has already occurred and thus things are the way they are because you did whatever the hell you did. So, while a circular event might happen (introducing the organic compounds necessary for life to develop in the era before life existed which would, of course, lead to one's own existence), it doesn't really matter because, well, the event already happened.

As for perfect knowledge of the universe, well, one would require something larger than the universe one wishes to have perfect knowledge of to be able to have such knowledge. By "something larger than", I mean both physically larger (by mass, at least) as well as having knowledge of all laws governing such a universe. Thus, a being such as LaPlace's Demon or God needs to be greater than the universe to have perfect knowledge of the universe.

As such, no physical being shall have perfect knowledge of the universe without being significantly larger than it.
