Hey everyone, first post here :) A while ago on another forum someone said that entanglement occurs in all reference frames (so is not subject to relativity of simultaneity). How is this possible? If two electrons are entangled and change spin (for example) how can these two events occur regardless of reference frame? Thanks for clearing this out (and sorry that I don't put this in the relativity or quantum physics board but I couldn't choose between the two. All of the best! S.
