The video explores the hypothesis that cosmic rays influenced the development of chirality in biological molecules on early Earth. Cosmic rays, which are high-energy particles from the sun, interact with the Earth's atmosphere, creating cascades of particles. These interactions may have led to an evolutionary preference for one type of chirality in organic molecules like DNA and RNA, resulting in the dominance of a single handedness in biological life.
