Interstellar travel
TopicHeard in 2 episodes across 2 shows since Jul 2026
Interstellar travel is the hypothetical travel of crewed or uncrewed spacecraft between star systems. Due to the vast distances between the Solar System and nearby stars, it remains extremely difficult and is not practicable with current propulsion technologies. Various theoretical concepts, such as generation ships, warp drives, and laser sails, have been proposed to overcome these immense distances.
