Extremely Low Frequency (ELF) Waves

Extremely Low Frequency (ELF) waves are 3-300 Hz electromagnetic signals whose ability to penetrate water made them the primary U.S. Navy communication channel for submerged nuclear submarines and a research focus in Soviet psychotronic weapons programs.

Extremely Low Frequency (ELF) Waves are electromagnetic waves with frequencies between 3 and 300 Hz. They are known for their ability to penetrate water and earth, making them useful for communication with deeply submerged submarines.1

In the context of Parapsychology, ELF waves were hypothesized as a possible carrier for ESP and Telepathy. Andrija Puharich and Jack Hammond conducted experiments using a Faraday Cage to test this theory, as Faraday cages do not block ELF waves. The idea was that if psychic abilities were not degraded inside the cage, it might suggest a connection to ELF waves.1

The U.S. Navy also invested significantly in ELF research for submarine communication. The alleged Soviet "rabbit experiment," where a mother rabbit's brain activity was said to correlate with the death of her kits on a submerged submarine, further fueled speculation about ELF waves as a medium for psychic information transfer.1
