For as long as science has studied sound, waves have been understood as forces that push—dispersing energy outward from their source. Now, researchers have demonstrated that carefully shaped acoustic beams can reverse this intuition entirely, pulling solid objects toward the source rather than away from it. Working with glass spheres positioned nearly ten centimeters from a transducer, the team achieved what had long eluded the field: a practical, material-agnostic acoustic tractor beam capable of acting on objects far larger than the sound's own wavelength. In doing so, they have quietly expa
