  1. @MetraMan09 But all branches are created at the same time.

  2. ​@MetraMan09 No, it's just basic quantum physics. Imagine you do the double slit experiment, and the electron either moves through the left slit (|Left⟩) or through the right slit (|Right⟩). So now it's in a superposition of left and right (√2(|Left⟩ + |Right⟩)). So there are basically two parallel worlds now, we can see. One where the electron went left and one where it went right. They both start to exist when the electron has to decide, which slit to take. So at the same time. And when you measure the electron after it turns into a superposition, you and the world get entangled with the state of the electron you measure, with both of the worlds, on of them being the world you recognize, which would be the point in time, when you measure the electron in both worlds, so the same time. Or is there a good reason, why this should be different?

  3. @MetraMan09 I even repeated in my explanation, that both worlds are created in the same time...

  4. ​@MetraMan09 So that's where the misunderstanding comes from. I was talking about branches created when one branch sub-branches. You won't find yourself in the one, which sub-branches the fastest, because all sub-branches are createt at the same time.

  5. On the other hand, every branch is the fastest then.

  6. @MetraMan09 Right, but I have the same distance to the place, where the measurement takes place in both branches. And if you talk about multiple branches, whose wave functions reach you at a different time: You won't end up in the branch of the first wave function, that reaches you, the second wave function also exists in that branch. Or they are both entangled, in this case, the second wave function might not be a superposition anymore, and no branching will take place.
