No, maybe you're the one who is wrong. Some scientists say there are multiple worlds like our own existing congruently with changes - big or small. It's a sort of multi-dimension theory that says anything that's possible exists, it just might not exist in our current world at this current time.

Maybe you and our Masamune switched places because of the spring?
