Giant Killer B, would a dice or an object in a drawer, as they exist on a much larger scale than the quantum scale, behave as you say they do? And. if we have this box in our universe, wouldn't five other boxes need to exist in these parallel universes? What if only one person in a parallel universe opens up the box? What if five people open up their boxes? The number on the dice in the sixth box would not be determined by a quantum probability, its number would already have been determined beforehand.

Would this be an example of quantum entanglement or quantum determinism?

FlyingAngel, Hmm...a two-sided mirror...I think both sides would reflect a parallel universe if this were in fact what's going on.

What I was thinking of was, if we *could* look through the back of a one-sided mirror, would we see the person looking at the mirror *and* his reflection looking back at him, reversed? Just a thought experiment. Maybe this is what someone in a parallel universe would see.

Its not the size of an object that determines if it behaves quantum mechanically its if information leaked from it is reaching you. However because larger objects leak more information its rare, under normal circumstances, that a macroscopic object sat before you will behave quantum mechanically. In physics information and heat energy are the same thing. So to make a macroscopic object behave quantum mechanically they have to cool it down to near absolute zero or find some other way of preventing heat leaked from it reaching you.

To answer your question about the magic box only one of them exists. Its the contents inside that are behaving as a real probability and therefore quantum mechanically. If an observer opens its lid then information leaks out into the universe. An observer receiving this information sees one outcome not the weird state of all outcomes co-existing at the same time (this is because gaining information on a probability collapses the probability).

If such information is prevented from reaching another observer then they could come along for their turn, open the lid, and stand a 5/6 chance of seeing a different outcome for the dice. Thats called a schrodinger cat paradox and means reality is unique to the information being gained by each individual. Or in more simple terms pretend everyone is sat in a virtual reality booth like in the film the Matrix experiencing their own version of reality.

Quantum Entanglement is when you have a real probability that links two or more objects (we'll take two and call them A and B ). If you measure the probability at A you also collapse it for B because its a single probability linking both objects. The outcome of the probability at A then determines the outcome of the probability at B. This is done faster than the speed of light regardless of distance between the two objects and is called quantum teleportation.

Photons are normally waves not particles and a wave is the same thing as a real probability. There isnt a parallel universe behind the mirror but the photon itself is in the weird state of multiple co-existing outcomes. All energy behaves like that under normal circumstances.

It sounds like you're trying to figure out how to access different dimensions but unfortunately you dont reach them through a mirror. Probabilities are best thought of as a little part of the multiverse and you may well be able to select the probabilities outcome. The experiments havent been done so I'm speculating below -

Engineer - He walks down the street and perceives his version of reality around him

Doctor - She walks down the street and perceieves a completely different reality because shes aware of different information.

Suicider - This unfortunate soul walks down the street and pereives their own reality too because they're only aware of negative information.

Trancer - The person in a trance has a closed down reality (tunnel vision) where they receive limited information.

What you perceive when you look out of your eyes determines how the little part of the multiverse collapses. Awareness of different information, by managing your own perceptions, collapses it in a different way.
