Sitting outside a Starbucks sipping his decaf latte, physicist Dr. Walter Dubois is doing equations on his laptop. He is working on the nature of subatomic particles existing within multiple dimensions. It is an extension of the Schrödinger Cat thought experiment, where a cat can be both alive and dead according to the universe outside the box the cat is contained in. Suddenly, a 1965 Ford Galaxy jumps the curb striking the doctor. Walter Dubois is dead, at least he is dead in this Starbucks, in this universe.
