The multiverse of Apple TV Plus’ Dark Matter is about to get bigger as the show heads into its second season. Apple announced on Friday that Dark Matter, Blake Crouch’s adaptation of his own 2016 novel about a physicist who gets sucked into multiple alternate realities, has been renewed for a new batch of episodes.

In a statement about the renewal, Crouch thanked the city of Chicago (where the series is set and was filmed) and described how “in the process of writing and filming season one, we discovered that there’s so much more story to tell.”

Especially with more seasons of shows like Severance and Silo on the way, the renewal is yet another sign of Apple really leaning into science fiction for its streaming platform. Though Dark Matter’s first season covered a significant amount of the book’s plot, the show introduced a number of original plot points that opened up possibilities for new stories down the line. Apple has yet to announce a projected premiere date for season 2, but the entire first season is available to stream now.
