Channel description
An epic exploration of possibilities. Join Peter and explore science-based hypothetical worlds across space, technology, Earth, and prehistoric history. Each episode begins with a simple “what if” question and follows real scientific theory, physics, biology, and astronomy to see where those ideas could lead.
Travel from deep space and alien planets to future technology and ancient life on Earth, and discover how small changes in science or history could reshape life, civilization, and the universe. It’s a blend of science education, imagination, and real research that helps you see our world, and the cosmos, from a fresh perspective.
