So somewhere in the world of something that's moving really fast, it appeared to them that the knight moved first then the bishop, while here on earth, the bishop moved first then the knight.
As the consequence of the knight moved first the king castle, the consequence of bishop moved first the queen check. So, if it turned out that the king castled, then we on earth should adhere to the reality that actually "knight moved first"... or should we?
Is this how multiverses were formed?
