I'm reminded of the Church–Turing–Deutsch principle[0] which states that a universal computing device can simulate every physical process. Putting that another way, I think it means that anything that can happen in the universe can be modelled by sets of equations (which we might not have yet) which can be calculated on a universal Turing machine. There is the question of what can quantum computers do polynomially or exponentially faster than a classical computer, but I think it's accepted that all quantum computations can be achieved classically if you don't mind waiting.
