Title: On the Status of the Measurement Problem: Recalling the Relativistic Transactional Interpretation,
Abstract: In view of a resurgence of concern about the measurement problem, it is
pointed out that the Relativistic Transactional Interpretation (RTI) remedies
issues previously considered as drawbacks or refutations of the original TI.
Specifically, once one takes into account relativistic processes that are not
representable at the non-relativistic level (such as particle creation and
annihilation, and virtual propagation), absorption is quantitatively defined in
unambiguous physical terms. In addition, specifics of the relativistic
transactional model demonstrate that the Maudlin `contingent absorber'
challenge to the original TI cannot even be mounted: basic features of
established relativistic field theories (in particular, the asymmetry between
field sources and the bosonic fields, and the fact that slow-moving bound
states, such as atoms, are not offer waves) dictate that the `slow-moving offer
wave' required for the challenge scenario cannot exist. It is concluded that
issues previously considered obstacles for TI are no longer legitimately viewed
as such, and that reconsideration of the transactional picture is warranted in
connection with solving the measurement problem.
