Superluminal transmission. View of a technician sending information faster than light (superluminal transmission). This experiment was performed by professor Gunter Nimtz at Cologne University, Germany. His experiments involved transmitting microwaves through a tunnel at superluminal speed. In the experiments, microwaves carrying Mozart's 40th symphony moved at 4.7 times the speed of light. He explained this using the tunnelling effect, a quantum mechanical phenomenon in which particles travel "through" an energy barrier instead of having to go over it. Nimtz says his results obey relativity, as the front waves still travelled at the speed of light.
