Remote Viewing refers to the attempt to gather information about a distant or unseen target using paranormal means or extra-sensory perception. The CIA, MI6, MI5, NSA, Mossad and many other intelligence agencies have taught agents to learn remote viewing for years.
Remote viewing was popularized in the 1990s, following the declassification of documents related to the Stargate Project, a 20 million dollar research program sponsored by the U.S. Federal Government to determine any potential military application of psychic phenomena. They also experimented with a project known as MK Ultra using LSD on unsuspecting participants.
Remote viewing, like other forms of extra-sensory perception, is generally considered as pseudoscience due to the need to overcome fundamental ideas about causality, time, and other principles currently held by the scientific community, and the lack of a positive theory that explains the outcomes.
