The guide-wave contains everything. It’s never collapsed, there’s no fade-away as you recede from the worldline. The rules governing the guide-wave are exactly those of quantum mechanics, which don’t mention any worldline. As far as the guide-wave is concerned, the worldline doesn’t exist. It’s a one-way connection. Right there we’ve got an oddity—the only entity in physics that would act without a reaction.
But setting that aside, the guide-wave implements the dynamics of branches not taken by the worldline. You see a nuclear decay? Nothing’s halting the guide-wave from implementing the portion of that decay that occurred in a different direction at a different time. So it does. So you have the dead cat component as well as the live cat component. Wigner’s friend is also still chilling out waiting for something to come up.
The guide-wave doesn’t know where the worldline went, so it keeps on ticking, following the time evolution operator—and, if you choose to break it into components, meticulously working out the consequences of every one of those components—whether or not the worldline happens to be anything like that.
If you want me to think something doesn’t exist, stop implementing its dynamics!
Can you unpack your argument against Bohm? Why does a real guide-wave require multiple worlds?
