Spaceships pushed by LIGHT – the future of space travel?

The video explores the concept of light sails, which are propelled by photons in space. It explains how photons, despite having no mass, can transfer momentum to light sails, allowing them to accelerate. The video discusses the mechanics of light sails, including the importance of reflectivity and momentum transfer. It highlights real-world applications, such as Japan's Ikaros and NASA's NanoSail-D, and emphasizes the advantages of light sails, including low cost and sustainability. The video concludes by noting the potential of light sails to revolutionize space exploration.
