Owl37400 and Tenson you could very well be correct. It is possable that the cable is aware of which way it is connected. From what I was taught at university there have been several experiments that show just this. It has been observed in 'youngs slit experiment' when using an extremely low power light source (one photon per second) that a diffraction pattern is formed. This would logically prove a consciousness of each other by seperate particles of light. These are separated by time and space yet know where the other has gone previously and alter there course accordingly to form the light and dark banding. The hypothesis that was put forward to me as a possable scientific explanation was that there was an unknown field or wave acting in another dimension (unknown medium) which enabled a physical interaction between the two particles. The question I asked myself was 'Does this prove a living intelligance exists in everything or can it be explained illogically by science? (which is an oxymoron in grammar alone).
