Researchers at Texas A&M University have developed a tiny device called a metajet that uses light refraction to steer in multiple directions simultaneously, potentially enabling directional control of light sails for interstellar travel. The silicon metasurface, measuring 0.01 millimeters across, demonstrated both levitation and horizontal movement when struck by a laser in water and could eventually be adapted for space propulsion or biomedical drug delivery applications.
