Only the universe in the light cone becoming entangled seems the most intuitively correct, and I don't see that this poses a problem... (I would say that it spreads at maximally the speed of light, and slower under some circumstances)
I dislike the "splitting of universes" analogy of MWI...
Here would be my analysis in MWI (which is probably flawed - so I would appreciate any help in understanding):
The photons A and B are entangled.
At Ta = 100 observer at A measures the photon, becomes entangled with A and B
At Tb = 100 observer at B measures the photon, becomes entangled with A...
Alright, I'm not very familiar with information space (so please correct me if I misinterpret something), but I don't see how this resolves the paradox.
Is the proposition that the information on the result of the measurement has always existed, and the two measurements independently retrieve...
A lovely attempt, but not likely to get anywhere... on the positive side, if it did, you'd probably get a Nobel prize.
But yes, there is a theorem that says you can't use entanglement to send information: there is no way to learn anything about the polarization of the measurement...
I think in this situation there is nothing at all being transferred (at least nothing usable). But you're right in that something (which is not information) can be "sent" using entanglement. Combined with a classical channel, this is quantum teleportation...
There's nothing to prevent knowledge about something far away appearing instantly. (sock example)
There is no information transfer: Information transfer require B be able to send some sort of message to A, which he can't. A will instantly know something, but B has no control over what that is...
I'm not sure it's reasonable to talk about the original universe. Why should one of them be original? If I were to take, say, a colony of bacteria and split it in half, which is the original colony? (bad analogy, but you get the idea)
I would say they are both equivalently original.
Me too...
You know the "infinite number of states" are just superpositions of two states, yes?
It can't, it is in TWO states at the same time, it is ONE of an infinite number of superpositions.
Just imagine theta written out in binary. It is an infinitely long binary string. You can store whatever you...
Yet as you say, there are no implications: as you've shown above, the position vectors are not affect by anything "quantumy", so whether or not they are fundamentally constant, they appear to be at least practically constant.
I would guess mini-you would measure position in this space in much...
Interesting... if we do not assume the consistency of space... the implications are fascinating.
Alright, I thought you had additional implications here.
But a direct measurement relies on nothing external to be made, correct?
Which you consider a problem, because if they have physical...
I think we have to conclude that "space" and "position" exist without theory and without measurement. I would find it more disturbing if the unit vector were somehow changed by QM.
How exactly do you mean they are akin to classical observables?
By direct measurement you mean some hypothetical...
