Entanglement is a fascinating, mysterious, thing in physics. Entangled particles can be galaxies apart, yet they change each other’s states instantaneously, in spite of the fact that a signal between them might take millennia to arrive. You can think of entangled particles as those twins who simultaneously pick up the phone to call each other, if you can imagine the twins always picking up the phone at the same time.
Entanglement is a wonderful mystery. My characters live in that wonderful mystery. I think we all feel like we’re entangled with many things, some of which we understand, some of which we don’t.
