    Not if you buy into the mainstream interpretations of quantum mechanics right? Initial conditions alone are not sufficient to predict what will happen.

    Academic is completely correct, even if the initial conditions were identical there is no reason the outcome should be.

    But it's a moot point, since current data quite definitively shows that there will be no big crunch for our universe.

    the possibilities of big crunch is impossible to current under standing. b/c the universe it accelerating

    That doesnt mean its impossible, just very unlikely. Again, you cannot predict what will happen from initial (or current) conditions alone. :) It goes both ways.

    We could have big crunch in the past.
    I like the idea that universe is symmetric, Universe wavefunction W is even: W(-t) = W(t)

    Unless the universe exists as a single structure with only one "bang" and "crunch", see the points about initial conditions.

    Nabeshin: Unlikely, but not impossible, and until there is a satisfactory explanation for the cosmological constant or dark energy, it is merely unlikely, not definitive.
