    Knowing current state of the univers, you can “predict” everything that has past

    The observer effect is irreversible. Quantum mechanics is reversible only because the effect technically falls outside of the mechanics.

    In related news, the entropy of a closed system is usually not constant.

      Wouldn’t the act of observing be baked in from the start, and therefore accounted for?

        I don’t know what you are trying to say. But you can’t predict the state something had before you observed it from the stuff you see.
