Netflix's new sci-fi series 3 Body Problem is a new take on an age-old question in speculative fiction: What would happen if humans made contact with aliens? Adapted from Liu Cixin's award-winnng Remembrance of Earth's Past book trilogy, the eight-episode series crosses time and space to depict the start of a centuries-long humanitarian conflict with the San-Ti, an extraterrestrial species on its way to Earth to take refuge from the inevitable demise of their own planet. 3 Body Problem's first season covers the human race's discovery of the San-Ti (which takes place decades after the aliens first communicated with one lone scientist) and early efforts to ensure our survival once they arrive, setting up an intricate, layered plot that will hopefully play out over many future seasons. It also introduces viewers to a heap of new scientific terms, both real and fictional, as preparations for the upcoming war play out across the globe. For anyone wondering where everything stands by the end of season 1, here's our breakdown of the 3 Body Problem season 1 ending, including every plot thread the finale sets up for a possible 3 Body Problem season 2.
