CIA's Alleged 'Ghost Murmur' Technology Raises Questions on Heartbeat Detection
Recent reports have emerged about a technology called 'Ghost Murmur,' allegedly used by the CIA to detect the electromagnetic signature of a human heartbeat from long distances. This claim surfaced following the rescue of an American Airman in Iran, where officials stated the pilot remained 'invisible to the enemy, but not to the CIA.' The technology is said to detect heartbeats using magnetocardiography, a technique that measures the magnetic field produced by the heart's electrical activity. However, experts have expressed skepticism, noting that the heart's magnetic signal is extremely weak and typically detectable only within centimeters of the body. The reports suggest that 'Ghost Murmur' might employ nitrogen-vacancy center magnetometry, a newer method using synthetic diamonds to detect magnetic fields. Despite the intriguing claims, the technology's ability to detect heartbeats from miles away remains unverified and inconsistent with known physics.
