Just jumping in here to have anons take a look at this.
So this is a Los Alamos Document I found on Through the Looking Glass with Phase Conjugation
The cover picture to the PDF is as shown. A little strange and it definitely goes down the Rabbit hole. If we have an Physics Anons who can tell us if this is about looking backward and forward in time using some type of technology it would be helpful.

And then I have noticed people mentioning Prometheus and I found this some type of Fission technology site.
