What if the thoughts you believe are yours were never yours to begin with? In this video, inspired by Carl Sagan's philosophy of cosmos and consciousness, we explore 5 scientific walls that dismantle the idea of free will and personal thought.
From Benjamin Libet's landmark neuroscience experiment — showing your brain decides before you do — to the 300-million-year evolutionary code running silently inside you, to the mirror neurons that make your emotions a reflection of everyone around you: this is the science of the mind you were never taught.
Carl Sagan said we are a way for the cosmos to know itself. This video is about what that actually means — for your thoughts, your identity, and your place in the universe.
