CIA's 'Ghost Murmur' Tech Can Hear Your Heartbeat From 40 Miles Away

In a recent episode of the Joe Rogan Experience, a startling claim emerged: the CIA has developed technology capable of detecting a person's heartbeat from 40 miles away. Dubbed 'Ghost Murmur,' the system reportedly uses advanced laser vibrometry to measure minute vibrations on surfaces—such as windows or walls—caused by sound waves from a heartbeat. This technique, often associated with spycraft, raises profound privacy concerns. While the existence of such capabilities has been speculated for years, this mention brings it back into the public eye. The episode underscores the ever-expanding frontier of surveillance technology.
