The Listening Stones of GCHQ
‘The Listening Stones’ at GCHQ in Cheltenham are a set of 9 large glacial granite boulders, worked and lettered individually on the theme of communication, and covered with code, ciphers, etc. It is interesting to note that the Negen Stones of Staines were also 9 in number (Negen is nine in Saxon).
The Stone Tape theory is a paranormal hypothesis that was proposed in the 1970s as a possible explanation for ghosts. It speculates that inanimate materials can absorb some form of energy from living beings; the hypothesis speculates that this “recording” happens especially during moments of high tension, such as murder, or during intense moments of someone’s life. This stored energy can be released, resulting in a display of the recorded activity. According to this hypothesis, ghosts are not spirits but simply non-interactive recordings similar to a movie.Paranormal investigators commonly consider such phenomena as residual hauntings.
