Photon propulsion

Photon propulsion is a method of spacecraft propulsion that uses light particles, called photons, to create thrust. When light is emitted from a source, such as a laser, it carries momentum. As photons leave the spacecraft, they push the craft in the opposite direction, similar to how a balloon moves when air escapes. This technique can potentially allow for efficient travel in space, as it doesn't require traditional fuels and can be powered by solar energy. While still largely experimental, it offers a promising avenue for future space exploration.
