Why rabbits and doorways
To be clear rabbits and movable walkways are representing photon polarization and movable doorways represent polarizers with changeable orientation. For facilitation of visualization of the coming together of polarizer and wave component of a photon and what will occur. For some people the analogy will be helpful for others an unnecessary layer of abstraction.
Rabbits and doorways. The basic apparatus
Set up similar to the doorways used in the paper called 'The unspooky violation of Bell's inequalities', but a suitable size for rabbits. Rectangular doorways are fixed into movable walls, allowing the door to be rotated. Rabbits are set moving in opposite directions, along fenced pathway to door from central point. A pair of rabbits are used in this way for each test. A movable barricade behind each rabbit, (or assistant's hand) can be used to prevent rabbits retracing path back to center.
Rabbits in space
Existential rabbit and existential doorway have an absolute orientation. Which is their unmeasured and unknown spatial orientation relation to all other existing things in the environment. How it appears to, the observation product generated by, an astronaut observer is a relative viewpoint.
(How can absolute orientation relate to, what is considered by mainstream physics, a point-like photon particle? There is a wave component associated with a photon that can account for wave like behavior. That wave can have an absolute orientation.)
What is important for a rabbit getting through a doorway is the relation between their absolute orientation, (rabbit-door), upon meeting. Non simultaneity for different observers is irrelevant to the coming together of existing things unseen in uni-temporal absolute space.
Imagine now the pathway the rabbits are on is fully rotate-able independent of the doorways.
Lets say this is a blind test and the result noting experimenter doesn't know anything about the rabbits being used. He only hears a noise such as a beep as a sensor in the floor is activated, or jingle bells being rung as rabbit passes by them upon entering the room beyond the doorway. Representing only knowing the outcome of particle test, and not the condition of the particle before testing.
A practicality, an attractive stimulus beyond doorway should encourage passing through. Eg. food or other rabbits.
Passes doorway, yes or no, is a score-like result added to model of the universe. It is not appearance of an existential rabbit in the universe. Likewise the particle test results are new, but they happen because of the relation of existential particle and apparatus. The particle is not becoming existentially real because of the result.
Preparation of rabbits
Rabbits can be prepared to be a correlated (test outcome0 pair.
In which case their walkways are level with each other. Meaning the rabbits approach the door at the same angle of approach. eg. Flat horizontal floors and vertical doors, or orientations giving the same relation relative to each other, allow both rabbits prepared have same orientations pass through. If both of the rabbits orientation is at 90 degrees to vertical because of a tilted walkway both will be stopped by the vertical doors.
The rabbits can be prepared as an anti correlated 9test outcome) pair.
In which case their walkways are at 90 degrees relative to each other. A pair of rabbits prepared to be anti-correlated will both pass though 90 degree difference in orientation doors, if their own rabbit orientation if sufficiently aligned. Either going through means the other goes through. Both fail to pass through if their own orientation is sufficiently misaligned. Either not going through means the other does not go through.
