What is déjà vu physics?
It turns out that we can actually induce forms of déjà vu in subjects in experiments. So there is a theory that says that déjà vu simply elicits fragments of memories that we have stored in our brain, memories that can be elicited by moving into an environment that resembles something that we've already experienced.
