Not to get too high-minded here but the most fundamental question of everyday life: &quot;why live at all?&quot; is greatly dependent on completely understanding the what we currently consider outermost fringes of physics.<p>Free Will in a deterministic universe is non-existent so there is no physical capacity for choice, but once we breached the quantum threshold all sorts of fun concepts began emerging (like multiverses for example) that bring that lack of capacity into question.
