(Phys.org) —A trio of researchers with the University of Tokyo in Japan has expanded the science of sound wave levitation by adding more speakers and controlling the focal point of the waves that are created. In so doing, as they describe in their paper they've uploaded to the preprint server arXiv, they have created a means for levitating and moving objects in three dimensional space.
