There are so many "mechanisms" so many people have come up with over many decades now to "interpret" these "relative probabilities" that have been experimentally recored. Sean Carroll has his "many worlds" or (another "possibility"): The offer wave going out in all directions and the many confirmation waves returning are a sort of subset of the infinite number of virtual photons traveling all possible paths between emitters and absorbers in Feynman's "sum-over-paths" path-integral formulation of quantum mechanics. Kastner proposes to regard the outgoing offer wave and many incoming confirmation waves as "possible <https://www.informationphilosopher.com/freedom/possibilism.html>" transactions, only one of which indeterministically <https://www.informationphilosopher.com/freedom/indeterminacy.html> becomes "actual." Kastner is a possibilist <https://www.informationphilosopher.com/freedom/possibilism.html> who argues that OWs and CWs are possibilities that are "real." She says that they are less real than actual empirically measurable events, but more real than an idea or concept in a person's mind. She suggests the alternate term "potentia," Aristotle's that she found Heisenberg had cited. For Kastner, the possibilities are physically real as compared to merely conceptually possible ideas that are consistent with physical law (for example, David Lewis <https://www.informationphilosopher.com/solutions/philosophers/lewis/>' "possible worlds." But she says the "possibilities" described by offer and confirmation waves are "sub-empirical" and pre-spatiotemporal (i.e., they have not shown up as *actual* in spacetime). She calls these "incipient transactions." ... https://www.informationphilosopher.com/solutions/scientists/kastner/ <https://www.informationphilosopher.com/solutions/scientists/kastner/#:~:text=Ruth%20Kastner%20is%20a%20physicist,possibilist%20extension%20of%20John%20G.&text=Cramer%20has%20explored%20the%20radical,backwards%20in%20time%20(retrocausality).> @philipthrift -- You received this message because you are subscribed to the Google Groups "Everything List" group.
