Ok I have my imagination running wild now. I am thinking of a sci fi story with mirror galaxies, solar systems, planets, and maybe even mirror people and mirror me. Hmm, who is that guy in the mirror, my dark side? Lol

Anyhow, my imaginations apart, I think this is a really cool hypothesis. And I was also able to understand most of it. One question came in mind regarding detection though. Say if electromagnetism has exactly same properties as mirror electromagnetism and strong force and mirror strong force, what does it mean for the detector. Say one in a billion event is caused by a mirror electron in LUX would we be able to tell it apart? Why or why not?
