Hi.
New member to this Physics forum and not a physicist, although have an interest in physics from a layman's position.
I saw a series of threads on a Twitter discussion posted about a year ago concerning Brian Cox and some other physicists concerning a statement made by Cox that the Pauli Exclusion principle work over macro distances, so that when an electron is excited in one part of the universe, all other electrons in the universe change their energy state, even if that change is at an imperceptible level. The argument was about whether there was a misunderstanding of the PEP, in that it should only work within a single atom or atoms in proximity so that there is an exchange of information between the two. One side states this is the case, the other side states that the PEP is valid even over vast distances.
Does anyone know what the current understanding of this issue is?
Many thanks
