Mirror Universe?

recently been reading about how some scientists believe they've found evidence that the Big Bang created 2 universes where Physics are the exact opposite....

Up is Down, Down is Up, Left is Right, Right is left....Time runs forward is our universe, time would run backward in The Mirror universe.

The more I read about their finding, research and Theories, I'm starting to feel that Is what Nolan's new movie is going to be about and explains why we are seeing Time running backwards in the some the action sequences....

thoughts?
