How do you know you're a person who has lived your life, rather than a just-formed brain full of artificial memories, momentarily hallucinating a reality that doesn't actually exist? That may sound absurd, but it's kept several generations of top cosmologists up at night. They call it: the Boltzmann brain paradox. Fabio Pacucci explores this mind-numbing thought experiment. [Directed by Skirmanta Jakaitė, Art Shot, narrated by Addison Anderson, music by Salil Bhayani, cAMP Studio].
