Ah, by ‘unitary’ I mean a unitary operator, that is an operator which preserves the Hilbert measure. It’s an axiom of quantum mechanics that time evolution is represented by a unitary operator.
Fair point about the probable finitude of time(but wouldn’t it be better if our theory could handle the possibility of infinite time as well?)
