Greatest Unsolved Mystery of the World

The Tao's Hum

 In the small town of Taos, New Mexico, there is a certain buzz often heard on the horizon that can be compared to the sound of a distant diesel engine. Although it can be heard by the naked ear, various sound detection devices are not able to pick it up. This is known as the Taos Hum and up to this day, no one still knows how this sound is being created.
