The original question was: All matter originated from a single point, does that mean all matter is entangled? The degree you usually hear about are “maximally entangled states”, but basically everything is a little entangled. Not because of the big bang, but because every-day interactions generate and break a little entanglement all the time. Just to be over-precise, when we say that things are entangled what we really mean is that some of their properties are entangled. Even less exciting, if you (personally) are the thing that’s entangled, your experience is entirely ordinary; the thing you’re entangled with will always be in a single state (from your point of view).
