> According to the Many World's idea, a Mach-Zehnder interferometer (or a quantum bomb tester) works the way it does because a world splits when the laws of physics allow it to change in two different ways, for example passing through a half silvered mirror AND being reflected by a half silvered mirror. Normally after a small change the difference only becomes larger, however if an experimenter is clever and very careful he can make a very tiny change that only exists for a very short time and then arrange things so that the two worlds become identical again, and thus merge back together. So in that merged world there are indications the photon went through the half silver mirror AND indications the photon was reflected by the half silver mirror. However no which-path information remains in the final merged world.<br>

> Some might object to what I say and insist that the branches were never fully separate worlds if they can still interfere, they were just different components of the same wavefunction. But if Many Worlds is correct then EVERYTHING is part of the same "Universal Wave Function", which is just another name for the multiverse.<br>
