Sound, as we know it, relies on a medium to propagate. Typically, it travels through particles in a medium, such as air or water, by causing them to vibrate. This fundamental principle has led to the common belief that sound cannot exist in the vacuum of space, where there is an absence of particles for sound waves to interact with.
Scientists from the University of Jyväskylä in Finland have successfully “tunneled” sound through a vacuum via an electromagnetic effect.
Researchers were able to transmit, or "tunnel," sound waves across small distances between two crystals in a vacuum.
Given the right circumstances, it is possible for sound to travel through a perfect vacuum.
