Optical Propulsion

Optical propulsion uses powerful light—often from lasers—to generate thrust in spacecraft or other objects. When the laser beam hits a target (such as a reflective surface or sail), it transfers energy and momentum, pushing the object forward. Unlike traditional fuel-powered engines, optical propulsion has no moving parts and can potentially achieve very high speeds over time. This technology leverages the momentum of photons, which have no mass but carry energy, to propel objects through space efficiently and quietly, making it a promising approach for future space exploration and rapid transport across vast distances.
