You could slip into a parallel universe and never notice. In fact this could be happening 400 billion times a second.

Love the way "universe" doesn't mean everything anymore. They keep pushing it with "multi-verse", "theory-of-everything"....

In my universe, universe means everything and "parallel universe" is a terrible term.

Which leads me to doubt the whole theory.
