Few shows in television history have the scope of Adult Swim’s Rick and Morty. For one thing, most shows take place only on our planet. And then, even if they involve space exploration, it’s usually only in our dimension (Star Trek, Battlestar Galactica). Meanwhile, shows that do take place throughout time, dimension, and space (Doctor Who) tend to deal in universes that recognizably resemble ours.

Lucky for us, in this dimension, Rick and Morty exists. Not only do the Sanchez/Smith family’s high jinks extend beyond our planet and dimension, the show switches its standard timeline halfway through season one. This allows us to glimpse into the ways life is both radically and subtly different within alternate realities. We also come to learn that Rick and Morty themselves exist in just about every possible reality — but that this is the only universe in which Rick actually cares about Morty. So perhaps this really is the best of all possible worlds. (Then again, at least in some of those other realities, Beth and Jerry are happy …)

Rick and Morty juggles so many universes that keeping track of them is a fool’s errand … but we attempted it anyway. Ahead, Vulture’s comprehensive list of every universe we know of in the world of Rick and Morty.

Note: These are only alternate realities, timelines, and dimensions, not other planets that exist within “our” reality. Also bear in mind that the show uses universe, world, and reality fairly interchangeably (we tried to stay faithful to whichever term the show used), but it uses timeline to refer to realities that were created when definitive decisions were made that created that reality (i.e., Beth not getting an abortion, Rick pressing the wrong button and causing the Ionic Defibulizer to explode).
