If neutrinos are going back in time (which is only one possible explanation) then you might be able to create some pretty fancy things like Paradox Buttons that cannot be pressed and so won’t be and so you can make “wishes” that the universe must satisfy… or the universe can stop you from making the button in the first place. There’s a Yudkowsky video about this which he calls the Grandma Extraction Problem. Starts at the 19th minute.
Please ignore the rationality problems caused by hoping for the universe to be structured in some preferred way.
What wrong with hoping for the structure of the universe to be one way rather than another? I do it all the time.
