The truth is, there are no alternate realities. At least not the way Penny describes them. Maybe an infinite multiverse is born from every action, whether it’s two atoms colliding or two people. Maybe reality is constantly fluctuating around us, but our senses aren’t equipped to detect those quantum variations. Maybe that’s what our senses are, an ungainly organic sieve through which the chaos of existence is filtered into something manageable enough that you can get out of bed in the morning . Maybe the totality of what we perceive with our senses is as clumsy a portrait of reality as a child’s chalk drawing on a sidewalk compared to the face of the woman you’re already falling in love with lying next to you in a mess of sheets and blankets, her lips still pursed as they pull away from your mouth.
