After the briefest of teases at the start of the year, Fox is ready to show Cosmos: Possible Worlds in earnest. The network has released an initial trailer that suggests Possible Worlds will follow the basic formula of the reborn series' first season while covering some decidedly different ground. As the name implies, there's a focus on extraterrestrial exploration and seemingly fantastical ideas. What would alien life be like, Neil deGrasse Tyson asks, and what are we doing to venture beyond Earth? There's even talk of exploring "paradoxical realities."
