Last year’s Stranger Things was notable for many reasons. Like Steven Spielberg and Stephen King before it, it managed to put relatable kids in real jeopardy in the darkest of situations. Between it being a love letter to the ‘80s, and all-around solid storytelling, it was a show that clicked with a whole lot of people, and went on to enter the pop culture zeitgeist in a big way.

Of course, if you’ve seen Stranger Things, you know that one aspect that plays a big role in the plot is the Upside Down. In the show, the Upside Down is a dark, morbid alternate universe where Will is trapped, and where the Demomgorgon lives. But what is the Upside Down from a scientific perspective?

In promotion of his new show, Bill Nye Saves the World, Bill Nye explained the theory of the multiverse.

The idea is simple enough to explain, and is undoubtedly the subject of many a stoner conversation. With every decision that is made, a new universe is created. So where you may have turned left in this universe, in an alternate universe, you turned right. Expound that idea on a global scale, and you have a general idea of how even the smallest of decisions can shape the world, and that these decisions pile up to create completely different universes. Obviously, the Upside Down seems to be the result of some pretty bad, dark decisions.

Of course, the theory of the multiverse isn’t exclusive to Stranger Things. Comic book fans are undoubtedly familiar with this theory, as it plays a huge role in the continuity (or lack thereof) in the stories. Additionally, the theory played a huge role in His Dark Materials, a book series from Philip Pullman that began with The Golden Compass. In that first book, we were led to believe that the plot existed in some strange version of the past, only to find out in book two, The Subtle Knife, that it took place in a present alternate universe.
