This makes for an interesting question: How do you test stuff like this?
It seems dangerous. What exactly breaks when you go back too far? Just the local area? Can I launch a time turner into space with a suitable automatic device and watch from a safe distance? Is having an observer involved relevant (more likely with magic than quantum mechanics)? Would testing with wizard or house elf participants be unethical? Is the anthropic principle relevant?
