The notion of living in a parallel universe is one of the strangest ideas in all of science, it emerged by complete accident from bizarre experiments and at first scientists resisted their findings but it wasn’t until a maverick in the field would force them to take it seriously.

The idea is that we are living in a bubble and you are just one of an infinite number versions of yourself, there could be many different variants of our reality out there. It can be an unsettling notion but in this film we examine the science and though a number of interviews with experts in the area we come to better understand what it all means.
