time will be refered to as the 4th dimention
assuming time is a dimention :
1. the 4th dimention progresses in intervals, a single line of time where one change
in one time line (a world) would chain effect the future worlds and or the past ones:
according to this, a time paradox could cause havoc or negation of time travel
this is the most complex of the examples. it might be possible using a worm hole
assuming the replecated worlds are intertwined, here is the interesting thing :
I think the said wormhole would "eat" the time traveler's effect potential. in other
words : the time traveler will experience a single moment of time travel and
the reappear in the moment after the time travel in other words : shortest range
teleport.but it might be possible using very much energy ( a black hole ).
2. the 4th dimention split advances, as in the 1st case the world is recreated at each
minimal amount of time (universal change), accourding to this free will does not exist
it is meaningless in the sense that it is completely dependant on the flow between
parallel worlds, the forth dimention here inflates like a baloon, and
the time traveler probablly won't have free will.
assumming time in not a dimention, it could just be a state change, according to this,
the past and the future don't exist, and choises (free will) are not random
there is a special case of the parallel worlds, which, to me, is like a regular travel.
and the case in which there is a parallel universe in which time jumps backwards,
also no freewill.
