    It's not about decisions or choices. Decisions are cognitive processes, very high level. A new quantum reality is spawned at any moment in time for every possible state a particle can have, so at the lowest level. A gazillion of particles are involved in a decision making process. By the time you made the conscious choice "left" or "right", a gazillion of alternate realities have already been created. It's absolutely not depending on hoo-mans making choices.

    I beg to differ. My sharp quantum mind splits universes like butter. That's why it's so random and rarely makes any sense.

    You want a great time travel story without paradoxes? Try this.

    Any real time travel is going to involve space travel.

    Fly really fast, and it is an express trip to the future--but it is one way, unless you take advantage of this: http://www.npl.washington.edu/AV/altvw86.html

    I have also read about getting two wormhole mouths, accelerating one at NAFAL speeds, then returning--so you have a time machine consisting of two wormholes say, in one room. That is as close to a time machine as you are likely to get, but it would look like two globes, not this: http://www.modelermagic.com/?p=55873

    But a wormhole may not be stable to enter at all, much less when "stretched."

    The only real hope of time travel into the past may be though the use of cosmological defects: http://www.dummies.com/how-to/content/crossing-cosmic-strings-to-allow-time-travel.html

    Only they have the moxie to pull it off--and then only if the two cosmic strings came close to one another in the past--a double-fly-by, were I to hazard a guess...

    Exploiting this type of time travel would be a major, one time undertaking--making D-Day preparations look small.

    Actually you can time travel based on the words time travel. Time - the measure of energy that a system uses when traveling along a path. Travel - to move along a path based upon the amount of energy needed to complete the traveling from point A to point B.

    So basically if you walk along a tape measure that is 30 feet long and remember the localized events in your mind and then walk back to each point you have metaphysically time travelled but in order for real time travel to occur all of the events of each moment on the tape measure would have to revert to that exact same position relative to the point on the tape measure meaning that the entire Universe would have to be in the state that was remembered at each specific point along the tape measure. Which an individual person is not capable of doing because of factors like ants and microbes not even knowing what Time Travel was.
