    I was thinking about the possibility of time travel...various theories etc... and what never sems to be brought into the conversation is that the universe is not only expanding..it's expansion is accelerating. That being the case...there is no reliable method to know where when is. Even if there are "worm holes" and assuming even if fleeting their "location" is stable even for an instant that location must change very rapidly as the universe expands.

    Also one must consider gravitational flex of the earth ... Your time traveller may find him or herself imbedded in rock as he or she "re-appears" on earth.

    If time is just the fourth dimension, wouldn't it move in concert with the other three. :eusa_think:

    Ya probably but they don't have precise measurement of the expansion of the universe...if we achieve the ability to dive into a worm hole created on earth there could be a wildly uncalcuable difference on when and where one pops out.. IF one pops out. :eek: :lol:

    This is way over my head, but why wouldn't gravity be slowing the expansion of the universe instead of allowing it to accelerate? As far as time travel goes, the traditional view would leave you in outer space if you went back to where the Earth was yesterday. An interesting take on this issue is Michael Crichton's Timeline, where different time dimensions existed concurrently in the same space, thus not leaving the time traveler out in the cold.

    We don't know that. We theorize that there are hundreds if not infinite "other" or alternate universes according to String Theory as I understand it but I have seen no rational that worm holes are predictable.

    They are pretty certain due to red shift measurements, that are extremely crude, that the known universe is not only expanding ...but accellerating. Then there is that whole dark matter/energy thing that is mindboggling in it's own right and we have NO idea what it's properties are if it even has any we are capable of measuring.

    What if I break the light barrier, get to your house and steal your cookies, then get out again before you see me?....When was I "there"?

    If you could do all that you would hit bank depositories and diamond mines vaults. I feel comfortble that if I had cookies..they would be safe.

    If it was possible the future time travelers would already have visited us. Hmmm maybe that's why JFK was assassinated to change the path our timeline was on.
