Initially derived from quantum physics, entanglement occurs when existents of different kinds share spatial and temporal micro- or macro- proximity in such a way that they cannot be described independently. This occurs regardless of whether their spatial proximity is one of milimetres or megametres, and/or temporal proximity one of minutes or millennia.

In critical theorist and physicist Karen Barad’s interpretation, entanglement is also the absence of any fixed dividing lines between ‘past’, ‘present’, ‘future’, ‘here’, ‘now’, ‘cause’, and ‘effect’.
