Dr. Lavling smiled.

“In ways. Remember that Schrödinger created his experiment to show that the consequences of quantum theory when applied to the macro world seemed ridiculous. But there are two different ways of looking at it. The first is that it is only the human mind that tells us that things need to be one way or the other. Why can’t the Universe be in some undefined, at least to us, state? But then, what about other Universes?

So at all points and at all time there is a possibility that the Universe is forking off to other Universes.
