Scientists engineered a synthetic metamaterial to direct mechanical waves along a specific path, which adds an innovative layer of control to 4D reality, otherwise known as the synthetic dimension.
Everyday life involves the three dimensions or 3D — along an X, Y, and Z axis, or up and down, left and right, and forward and back. But, in recent years scientists like Guoliang Huang, the Huber and Helen Croft Chair in Engineering at the University of Missouri, have explored a “fourth dimension” (4D), or synthetic dimension, as an extension of our current physical reality.
