Cosmos - Characters & Cast

Tyson's motivation, both stated and demonstrated, is to ignite curiosity and share the power and wonder of the scientific perspective with the widest possible audience. He aims to bridge the gap between the scientific community and the general public, demonstrating why science is not just a subject in school but is essential to our survival, our culture, and our deepest sense of self. He seeks to empower viewers with knowledge and inspire the next generation of 'searchers.'

As the host, Neil deGrasse Tyson's role is not one of dramatic change, but of guiding the audience on a journey of intellectual and emotional discovery. He begins as the inheritor of Carl Sagan's legacy, standing on the same cliffs where the original series began. Throughout A Spacetime Odyssey, he is the enthusiastic and clear-eyed teacher, breaking down complex ideas. In Possible Worlds, his tone evolves slightly, becoming more urgent and hopeful as he presents visions of humanity's future, solidifying his role as a passionate advocate for a scientifically literate and aspirational society.
