Faster-than-light equipment

Faster than light experiment. View of professor Gunter Nimtz and the equipment he used to send information faster than light. Nimtz works at the University of Cologne, Germany. His experiments involved transmitting microwaves through a tunnel at superluminal speeds. In Nimtz experiments, microwaves carrying Mozart's 40th symphony moved through the tunnel 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
