It may still be a few years away from practical use, but scientists have created a real tractor beam, like the ones featured in the "Star Trek" TV series and movies.Simply put, this technology utilizes a beam of light to attract objects, according to the University of St. Andrews in Scotland. In "Star Trek," tractor beams were often used to pull spaceships and other objects closer to the focal point of the light source attached to another ship.
