““I was reading a book about the cosmos recently,” he says, and then he looks around and goes, “Hold on, trust me, this relates.” The crowd laughs again. “And I was reading about different theories about the universe. I was really taken with this one theory that states that everything that is possible happens. That means that when you flip a quarter, it doesn’t come down heads or tails. It comes up heads and tails. Every time you flip a coin and it comes up heads, you are merely in the universe where the coin came up heads. There is another version of you out there, created the second the quarter flipped, who saw it come up tails. This is happening every second of every day. The world is splitting further and further into an infinite number of parallel universes where everything that could happen is happening. This is completely plausible, by the way. It’s a legitimate interpretation of quantum mechanics. It’s entirely possible that every time we make a decision, there is a version of us out there somewhere who made a different choice. An infinite number of versions of ourselves are living out the consequences of every single possibility in our lives. What I’m getting at here is that I know there may be universes out there where I made different choices that led me somewhere else, led me to someone else.” He looks at Gabby. “And my heart breaks for every single version of me that didn’t end up with you.””
