"Think of the universe as a deck of cards, began the explanation. "Now, if you shuffle that deck, there's just so many orderings that can happen. If you shuffle that deck enough times, the orders will have to repeat. Similarly, with an infinite universe and only a finite number of complexions of matter, the way in which matter arranges itself has to repeat."

Did you get that?

I knew I'd be lost at the deck of cards metaphor since I've managed War and GoFish, but can't seem to get how to count points when playing Gin Rummy. 

But what did perk my interest, listening to NPR one morning last week, was the concept of parallel universes.

So, seeking a better explanation of this, I went to Wikipedia, the arbiter of unfounded, undocumented information. Multiverse, as they called it, was incomprehensible too. 

Okay, okay, I thought. I can rise to the occasion, I'll keep searching.

While I still find it beyond my ability to grasp, this particular quote struck me as enough to satisfy my lack of interest to pursue this further. " A strange discovery by quantum Physicists means that an object you see in front of you may simultaneously exist in a parallel universe–a multi state condition that has scientists theorizing that teleportation and time travel may be much more than just the plaything of science fiction writers."  

Think about it, Peggy Sue Got Married, Back To the Future I, II, III and IV, Time And Again, all are possible. And wouldn't you, given the opportunity do it differently, make different choices, perhaps have not eaten that third helping of cake? 

I would.
