 Before turning to one of the more significant objections to the transactional interpretation, and to retrocausality in general, it is instructive to tease apart here two complementary descriptions of this transaction process. On the one hand there is a description of the real physical process, consisting of the passage of a particle between emitter and absorber, that a temporally bound experimenter would observe; and on the other hand there is a description of a dynamical process of offer and confirmation waves that is instrumental in establishing the transaction. This latter process simply cannot occur in an ordinary time sequence, not least because any temporally bound observer by construction cannot detect any offer or confirmation waves. Cramer suggests that the “dynamical process” be understood as occurring in a “pseudotime” sequence:
