So what? I'm assuming that some people have some models of physics based on equations, and those don't happen to be of the kind where the state for some t <= T

So what? I'm assuming that some people have some models of physics based on equations, and those don't happen to be of the kind where the state for some t <= T determines the state for t > T. Ok, great - does that predict or explain or simplify anything interesting about the observable universe?
