Does model imply a theory which predicts the evolution of states (possibly probabilistic) so that the state of universe yesterday limits what might exist today? No. Model means a mathematical object. One specific, unchanging, crystalline object you can hold in your hand and look at from a

Many thanks for your fine answers, and patience with an ignorant. When I said probability I meant from the frequentist side, or from what Tegmark has called bird's point of view (which I guess corospond to what Tom calls God's point of view, - whether or not one believes) But the subjective

since it's a sequence of trillions and trillions of real (micro-)events. PS. Of course a macro-event is also real but it's not a fundamental event, and therefore the concept probability must be USED differently here, even though the concept itself is the same. Does that sound right
