Another way in which MWI is falsifiable is that it would be proven wrong if those Chinese physicists were able to show a speed limit on the spooky action at a distance. MWI says that there is no such speed limit, since there is no spooky action at a distance. Additionally, there are collapse theories that are much easier to test than consciousness-based ones. By "much easier", I still mean fantastically difficult, but should the day come that one of these collapse theories is proven correct, then MWI will clearly have been falsified.
