You can make predictions based on what the quantum particle was doing in the interim. And part of the reason I like it is it's exactly what we have to do in cosmology. We live in the universe we're not in a scattering matrix we're in the middle of the thing. So we're after the big bang but we're before the end, we're coupled to it right. We're coupledvery weekly so whatever we measure the Hubble constant to be does not the universe doesn't give a
