This decided to write this after reading Puffy1980 opuss on Time Travel.
This does not give evidence for 'time travel' itself but gives evidence for how it might bypass the butterfly effect conundrum.
Determinism is the view that the universe operates to a series of strict universal laws which cannot be broken. There will only ever be one outcome. Hard determinism is the view that this renders humans 'free will' not free, but determined and that actually 'free will' is a misconseption. If the universe is a deterministic one, then traveling backwards in time would be necissary (non philosophical sence). I am not saying that we MUST time travel. I am saying that IF we did, then it would've been determined and actually be part of the reason the world is how it is today.
What if I shot George Bush? Using Theory 1 - Split timelines, there would be a world where he was dead and a parallel timeline where he was not.
Using theory 2 - Hard determimism, you would decide not to or something would prevent you from doing so, otherwise he would've been dead in the present.
If you do not believe in hard determinism that is fine, I don't want to shake anyone's belief, just get my opinion out there.
But consider this. Time 'A' is now. Imagine a parallel universe starting from this point. This is also A. Run them for five minutes and pause. A+5=A+5, that is necissary. In other words, both timelines would be EXACTLY the same. A libertarian (believes in freewill) would say that in that situation, the agents could have made any decision they like and that A+5 does not equil A+5.
Feel free (or not =P) to leave any comments and discuss. =]
