A “tractor beam” is a science-fiction term that refers to a device capable of pulling in distant objects without any physical contact.
As any true Star Wars fan could tell you, the Death Star was equipped with hundreds of tractor beam generators that were used to seize and capture ships like Han Solo’s Millennium Falcon. But even those who are not quite geeky enough to get those references will still be amazed to know that scientists have now created a real-life sonic tractor beam that can be used to hold, move, and even rotate small objects completely without touch.
