“He said that in quantum physics every alternative possibility happens simultaneously. All at once. In the same place. Quantum superposition....Every universe exists over every other universe. Like a million pictures on tracing paper, all with slight variations within the same frame. The many-worlds interpretation of quantum physics suggests there are an infinite number of divergent parallel universes. Every moment of your life you enter a new universe. With every decision you make. And traditionally it was thought that there could be no communication or transference between those worlds, even though they happen in the same space, even though they happen literally millimetres away from us.”
