What the #$*! Do We Know!? Part 6
Continue with Cramer’s Transactional Interpretation:
The latter half of my review article[1] provides examples of the use of the transactional interpretation in analyzing the accumulated curiosities and paradoxes (the EPR paradox, Schrodinger’s cat, Wigner’s friend, Wheeler’s delayed choice, Herbert’s paradox, etc.) that have lain for decades in the quantum mechanics Museum of Mysteries. It is shown that the TI removes the need for half-and-half cats, frizzy universes with split ends, observer-dependent reality, and “knowledge'’ waves. It removes the observer from the formalism and puts him back in the laboratory where he belongs.
Really? And it happens just because of transactions between advanced and retarded waves? Waves of what? Did Cramer forget that Quantum Field Theory (QFT) - the most advanced part of quantum mechanics - is about quantum fields - that is about operator-valued functions of space and time? There are no waves there - as QFT, especially relativistic one, is usually represented in a Heisenberg picture, not the Schroedinger picture. It is operators that "move in space and time", no wave functions. Moreover, in open systems, and all realistic systems are open, states are represented by density matrices, not by "waves". It is hard to believe that Cramer does not know these elementary facts. (That is elementary, dear Watson!) But if he knows them - how can he not address these fundamental issues at the very beginning? Only because other physicists are all to busy with their stuff so that they have no time to read about "Transactional Interpretation?"
To be continued…
