Honestly if a scientist from Washington came to the character and told them what happened the characters would just shrug and say ‘Oh… okay…’ it wouldn’t change their lives at all… and…
I know… but it’s a crazy sci-fi thing that would make the story all that much weirder.
That seems like a very J.K. Rowling thing to do. It couldn’t be less important to the story and the lives of these characters.
Maybe years after it’s all over I’ll just casually mention it in an interview.
