We normally think that only objects with mass can exert force, yet sunlight can move spacecraft, push microscopic particles, and even exert pressure on everything it touches. The secret lies in one of the most surprising discoveries in physics: light doesn't need mass to carry momentum. In this video, we explore how photons transfer momentum, why light exerts radiation pressure, how solar sails can travel through space without fuel, and what Einstein's theory of relativity reveals about the relationship between energy, mass, and momentum. If photons have no mass, how can they physically move something? The answer challenges our everyday understanding of force and motion.
