According to the theory of "brain in a jar", the possibility that everything we know is virtual is infinitely close to 100%, which is similar to the code in programming that goes back to a certain node, and the code at any node can be considered as an independent program, which seems to be understood as an independent universe at any point in time. I believe that there is a "result", and there is a "cause", which seems to be the same truth in quantum mechanics
