TED: How humanity can reach the stars | Philip Lubin

The video discusses the potential for interstellar travel using light propulsion. It explains how phased arrays of lasers can propel small spacecraft to significant fractions of the speed of light, enabling exploration of nearby stars like Proxima Centauri. The technology relies on advancements in photonics, similar to those used in high-speed internet. The video also covers the economic and technological challenges of making this feasible, as well as the potential for remote sensing and exploration of exoplanets. The transformative impact of finding life on other planets is highlighted.
