TRACTORBEAM

Tractor beam

A tractor beam is a device with the ability to attract one object to another from a distance. The term was coined by E. E. Smith in his novel Spacehounds of IPC . Since the 1990s, technology and research has laboured to make it a reality, and have had some success on a microscopic level. Another method to realize tractor beams is based on the use of biaxial birefringent media. Less commonly, a similar beam that repels is called a pressor beam or repulsor beam. Gravity impulse and gravity propulsion beams are traditionally areas of research from fringe physics that coincide with the concepts of tractor and repulsor beams.
