Roey Tzezana: Could human civilization spread across the whole galaxy?

Could human civilization eventually spread across the whole Milky Way galaxy? Could we move beyond our small, blue planet to establish colonies in the multitude of star systems out there? These questions are pretty daunting, but their (theoretical) answers were actually put forth decades ago. Roey Tzezana describes the conceptual von Neumann machine. [Directed by Eoin Duffy, narrated by Addison Anderson, music by Wesley Slover].
